13 AMERICAN GAS ASSOCIATION ANTITRUST COMPLIANCE GUIDELINES Introduction The American Gas Association and its member companies are committed to full compliance with all laws and regulations, and to maintaining the highest ethical standards in the way we conduct our operations and activities. Our commitment includes strict compliance with federal and state antitrust laws, which are designed to protect this country s free competitive economy. Responsibility for Antitrust Compliance Compliance with the antitrust laws is a serious business. Antitrust violations may result in heavy fines for corporations, and in fines and even imprisonment for individuals. While the General Counsel s Office provides guidance on antitrust matters, you bear the ultimate responsibility for assuring that your actions and the actions of any of those under your direction comply with the antitrust laws. Antitrust Guidelines In all AGA operations and activities, you must avoid any discussions or conduct that might violate the antitrust laws or even raise an appearance of impropriety. The following guidelines will help you do that: Do consult counsel about any documents that touch on sensitive antitrust subjects such as pricing, market allocations, refusals to deal with any company, and the like. Do consult with counsel on any non-routine correspondence that requests an AGA member company to participate in projects or programs, submit data for such activities, or otherwise join other member companies in AGA actions. Do use an agenda and take accurate minutes at every meeting. Have counsel review the agenda and minutes before they are put into final form and circulated and request counsel to attend meetings where sensitive antitrust subjects may arise. Do provide these guidelines to all meeting participants. 3 Do not, without prior review by counsel, have discussions with other member companies about: your company s prices for products, assets or services, or prices charged by your competitors costs, discounts, terms of sale, profit margins or anything else that might affect those prices the resale prices your customers should charge for products or assets you sell them allocating markets, customers, territories products or assets with your competitors limiting production whether or not to deal with any other company any competitively sensitive information concerning your own company or a competitor s. Do not stay at a meeting, or any other gathering, if those kinds of discussions are taking place. Do not discuss any other sensitive antitrust subjects (such as price discrimination, reciprocal dealing, or exclusive dealing agreements) without first consulting counsel. Do not create any documents or other records that might be misinterpreted to suggest that AGA condones or is involved in anticompetitive behavior. We re Here to Help Whenever you have any question about whether particular AGA activities might raise antitrust concerns, contact the General Counsel s Office, Ph: (202) ; GCO@aga.org, or your legal counsel. American Gas Association Office of General Counsel Issued: December 1997 Revised: December 2008

14 Fire Alarms and Exits In the event of an emergency, hotel guests will be notified via alarm and/or loudspeaker whether the hotel should be evacuated. Please make yourself aware of the closet emergency exit.

41 ASC Z223 NFPA 54 COMMITTEE ON NATIONAL FUEL GAS CODE Minutes ASC Z223 / NFPA 54 National Fuel Gas Code Committee Hilton Palm Springs Resort Palm Springs, CA October 16-18, Call to Order, Self-Introductions & Attendance: Chair, Tom Crane, called the meeting to order and members and guests introduced themselves. (Attachment A). 2. Adoption of Agenda: The agenda was approved as distributed. 3. Announcements: Participants were made aware of the fire alarms/exits and the AGA antitrust guidelines. 4. Membership Review: a. ASC Z223 Committee Updates The membership roster and interest category balance was reviewed. Mr. Franklin Switzer s new member ballot was conducted and approved. The committee is in balance in accordance with its operating procedures. b. NFPA 54 Committee Updates The membership roster was reviewed. The NFPA Standards Council is responsible for maintaining committee balance and was noted that it is in balance. 5. Approval of Committee Meeting Minutes: The November 2011 full committee and October 2012 Advisory Panel minutes were approved as distributed. 6. Future Meeting Schedule & Need for Advisory Panel Meetings: a. The proposed 2013 & 2014 meeting schedule was reviewed without changes (Attachment B). A motion was made and approved to recommend that the June 2013 meeting be held in Portland, ME. b. The committee discussed the future need for advisory panel meetings to screen public input in light of a decline in received input. The committee consensus is that the advisory panel meetings are useful by providing initial review and recommendations. The panel meetings should be held for the next revision cycle. 7. NFPA Revised Process Presentation: Denise Beach provided an overview of the revised NFPA process. 8. CSST Discussion: a. AHRI Research Presentation: AHRI has contracted with GTI as their main contractor for the CSST bonding research. GTI provided a presentation on the current research project scope and initial results. Previously, Phase I research conducted under the National Fire Protection Foundation was completed. Phase 2 test objectives will address the NFPA Standards Council decision and the Phase I report findings. The primary focus will be on bonding effectiveness. A simulation model was developed and its validation is to be included. Testing simulates near lightning strikes and bonding performance. The goal is to complete the original scope of work by the end of /08/13

42 ASC Z223 NFPA 54 COMMITTEE ON NATIONAL FUEL GAS CODE b. Committee Discussions: The NFPA 54 CSST Task Group met to consider the GTI presentation preliminary findings. They provided the following discussion item for full committee consideration: The findings indicate a need to limit the jumper length to perhaps 100 ft. The findings indicate that the code s current 6 gauge bonding jumper is adequate. Individual Committee member points: A benchmark may be needed, perhaps copper tubing bonded through the appliance grounding means. Then an equivalent level of protection could be determined for CSST. The research does not point to a maximum length, only 100 ft as a simulation. There is concern that the research may not have answered all of the NFPA Standards Council questions raised in their initial finding. The researchers realize that their work is not complete. Additional data is needed prior to setting any code requirements. What is safe enough? The NFGC has never been a lightning code and now finds itself addressing lighting. The researchers reported that the jacket was removed to test for arching. Neither the simulations nor the tests include the jacket s influence on bonding and no conclusions to its effectiveness are made. Responding to the NFPA Standards Council concerns is critical and the research must provide the technical basis for those answers. NFPA has fire data for gas related lightning incidents that cover all piping materials and appliance connectors. There is no evidence that the data trend after CSST became widely used has changed. While CSST is the subject of this research the committee may wish to consider all gas piping systems and connectors. Canadian and European codes all require 6 gauge wire direct bonding. GTI is a valid laboratory and their research should be considered adequate to address Standards Council concerns. Benchmarking CSST with copper and or steel may not be necessary. There is more evidence of CSST failures than copper (another thin wall piping material). The Phase I report laid out a research plan which did not include the need to test other piping materials. The research in finally being provided to the committee which will provide a good basis to identify parameters for code revisions. It appears the first step would be for the committee to start with some limits on bonding length. c. Code Requirements and Possible Revisions: The committee reviewed the public input logs regarding CSST. A committee input was created to address current research findings to solicit public comments and input. There is some concern that additional research is necessary to demonstrate that the energy level simulated, and the test, represents a reasonable input level to judge acceptability. Industry is encouraged to provide justification that the level represents a reasonable expectation for survivability. 4/08/13

43 ASC Z223 NFPA 54 COMMITTEE ON NATIONAL FUEL GAS CODE Staff recommended that the ballot be held until 1/18/13 so it would include a written report. 9. Consideration of Public Input and Committee Input: The committee reviewed and took action on public input considering the advisory panel recommendations. First revision draft changes and Committee Input was approved for letter ballot. 10. New Business: A Bio Gas Task Group was formed to determine if the scope of the NFGC could be expanded to include piping systems and equipment designed for use with bio-gases. The NFGC Task Group members are Swiecicki (Chair), Caudle, Gress, and Holmes. NFPA staff will solicit additional members from appropriate NFPA technical committees and other standards organizations. 11. Adjourn: With business completed, the committee adjourned on October 18 th at 12:07 p.m. 4/08/13

53 National Fire Protection Association Report Page 1 of 95 5/13/2013 Public Comment No. 64-NFPA [ Global Input ] L ASTM D2513 change in title and date change from -09 to -12. Additional Proposed Changes File Name Volgstadt_Public_Comment_re_PA11_and_D2513_NFPA_54-15_Proposal..pdf Description Approved Original Comment Statement of Problem and Substantiation for Public Comment The problem is that the proposed revision to NFPA removes the use of PA11 piping, a piping system which is permitted in the 2012 edition. This situation can be rectified by a retaining reference to D and correcting the title to Standard Specification for Thermoplastic Gas Piping, Tubing and Fittings. The better resolution is to reference D and add reference to F2945 Standard Specification for PA11 gas Piping, Tubing and Fittings and editorially changing any PA11 references in the Code to the PA11 standard, namely F2945.

54 National Fire Protection Association Report Page 2 of 95 5/13/2013 Public Comment No. 66-NFPA [ Global Input ] 5.9 Overpressure Protection Where required. Where the serving gas supplier delivers gas at a pressure greater than 2 psi for piping systems serving appliances designed to operate at a gas pressure of 14 in. wc or less, overpressure protection devices shall be installed. Piping systems serving equipment designed to operate at inlet pressures greater than 14 in. wc shall be equipped with overpressure protection devices as required by the applicable equipment construction and/or installation codes and standards for the connected equipment Pressure limitation requirements Where piping systems are required to be equipped with overpressure protection devices by paragraph each overpressure protection device shall be adjusted to limit the gas pressure to each connected appliance to 2 psi or less upon a wide-open failure of the primary line pressure regulator Each overpressure protection device installed to meet the requirements of this section shall be capable of limiting the pressure to its connected appliances as required by this section independently of any other pressure control equipment in the piping system Each gas piping system for which an overpressure protection device is required by this section shall be designed and installed so that a failure of the primary pressure control device(s) is detectable Each pressure relief valve shall be designed to maintain downstream pressure at or below the limits specified in paragraph at a gas flow rate equal to or greater than that supplied to it by a regulator failed wide open at the regulator s design operating inlet pressure. Type your content here... Additional Proposed Changes File Name Description Approved NFGC_Comment_5.9.docx original comment Statement of Problem and Substantiation for Public Comment These proposed provisions of CI 59 are not clear and should be further developed appears to exempt most residential gas systems since the normal pressure of the gas supplied is around 14 inches water column. However the gas pressure upstream of the point of delivery is often significantly higher. The issue is not whether the supply delivers gas at more than 2psi; rather it is can the pressure of the gas being delivered ever exceed 2 psi. What is the purpose of ? This provision would require the pressure relief valve to maintain the gas flow rate at all pressure above normal up tp 2 psi.. If an appliance is designed to operate at 14 inched wc and the pressure relief valve is acting such that the gas pressure is 1.75 psi the flow rate is not the major concern. While this may not be the intent, this provision implies that it is expected that the appliance will continue to operate in the example described above.

57 National Fire Protection Association Report Page 6 of 95 5/13/2013 Public Comment No. 69-NFPA [ Global Input ] * CSST. CSST gas piping systems shall be bonded to the electrical service grounding electrode system The bonding jumper shall connect to a metallic pipe or fitting between downstream of the point of delivery and the first downstream CSST fitting The bonding jumper shall not be smaller than 6 AWG copper wire or equivalent. Gas piping systems that contain one or more segments of CSST shall be bonded in accordance with this section The length of the jumper between the connection to the gas piping system and a grounding electrode system shall be as short as practical, but shall not exceed 150 ft (45.6 m) 75 ft. (22.9 m). Any additional electrodes shall be bonded to the electrical service grounding electrode system Where a gas piping manifold is installed, it shall also be bonded to the electrical service grounding electrode system. Additional Proposed Changes File Name Description Approved NFGC_Comment_Form_ pdf original comment Statement of Problem and Substantiation for Public Comment The results of the research being done for the GTI Phase II CSST bonding research project demonstrate that CSST bonding is effective as long as the bonding clamp is located anywhere between the point of delivery and the appliance(s) shut-off valve. The results also indicate that shorter bonding conductors will reduce the level of imposed energy on the CSST as well as reduce the residence time of the energy imposed on the CSST. The recommended 150-ft length is well within the conditions used in this research for demonstrating that bonding is effective. The results from the research also indicate that the incremental improvement in bonding effectiveness by installing multiple bonding connections is so minor such that it does not support the special requirement, , for piping manifolds.

An A commercial, industrial, or institutional appliance needing a chimney capable of withstanding a continuous flue gas temperature not exceeding 1000 F (538 C). Statement of Problem and Substantiation for Public Comment As a representative of the GOT Committee, I can report that the GOT committee is against this change. The GOT Committee's work has been to create general and consistent definitions of the same term throughout the NFPA system of documents, therefore we do not advocate the deletion of an extracted definition in favor of creating a unique definition. At the same time, the Committee acknowledges that the change to the definition that was agreed on by the NFPA 54 Committee creates a more generic definition. The 54 Committee may want to submit a proposal to the NFPA 211 Committee and recommend they change their definition and extract it from NFPA 54.

Where the gas supply design pressure in piping systems located indoors exceeds 2 psi (14 kpa) and line pressure regulators are installed to reduce the serve appliances designed to operate with a gas supply pressure to of 14 in. w.c. (3.4 kpa) or less, all of the following shall apply: (1) Regulators shall be provided with factory-installed overpressure protection devices. (2) Overpressure protection devices shall limit the pressure downstream of the line pressure regulator to 2 psi (14 kpa) in the event of failure of the line pressure regulator. Statement of Problem and Substantiation for Public Comment Remove "design', which add ambiguity to the requirement. The other language added claries that the requirement speaks to those appliance that are not rated for pressures higher than 14"WC. If it does, then this requirement applies to gas engines, boilers, and industrial equipment that are designed to handle pressure above 14"WC. The unintended consequence is that 2 PSI would be the maximum permitted pressure to the appliance. For gas engines, boilers, and industrial equipment, this would be design restrictive.

81 National Fire Protection Association Report Page 37 of 95 5/13/2013 Public Comment No. 35-NFPA [ New Section after 5.13 ] TITLE OF NEW CONTENT EFV Minimum Supply Pressure New Section & Type your content here... TITLE OF NEW CONTENT 5.13 Excess Flow Valve(s) General. Where automatic excess flow valves are installed, they shall be listed for the application and shall be sized and installed in accordance with the manufacturers' instructions Minimum Supply Pressure. Where one or more excess flow valves are installed in a piping system or appliance connection, the minimum pressure at the inlet of each appliance downstream from the excess flow valve or valves shall be 5.5 in. w.c. for natural gas and 11 in. w.c. for LP gas. The pressure shall be measured with all appliances downstream of the excess flow valve or valves operating at their full input rate. Statement of Problem and Substantiation for Public Comment The code currently contains minimum coverage for the installation of excess flow valves (EFV). The current coverage requires the installer to follow manufacturer s installation instructions for their selection and installation. Since an EFV will have a higher pressure loss than typically installed piping components, the code will need to help ensure that the piping system will have the required capacity to meet the inputs of the connected appliances. AGA is proposing a simplified approach to help ensure that gas piping systems incorporating an EFV are properly designed. The proposed approach allows the continued use of the code s piping sizing tables without the need to add equivalent lengths to take into account the EFV s pressure loss. This helps avoid confusion regarding sizing of piping. To address these installations, a minimum inlet pressure to the appliance would be specified. The proposal s minimum inlet pressure is the minimum pressures specified by most appliance manufactures in their installation instructions. These minimum inlet pressures help ensure proper appliance operation. While the code currently requires that appliances be provided with sufficient pressure for their operation, this requirement does not anticipate low abnormal operating pressures that may be present on extremely low pressure delivery systems during a peak heating period.

87 National Fire Protection Association Report Page 44 of 95 5/13/2013 Public Comment No. 71-NFPA [ Section No ] Piping Through Foundation Wall. Underground piping, where installed through the outer foundation or basement wall of a building, shall be encased in a protective sleeve or protected by an approved device or method. The space between the gas piping and the sleeve and between the sleeve and the wall shall be sealed to prevent entry of gas and water. shall be brought above finished ground level before entering a building and shall be installed in accordance with Section Additional Proposed Changes File Name Swiecicki_P_I_15-7_1_5.pdf Description Approved Cover Sheet Statement of Problem and Substantiation for Public Comment This proposal will establish consistency between the National Fuel Gas Code and the International Fuel Gas Code. The International Fuel Gas Code was changed in 2009 to prohibit the penetration of gas piping through a foundation wall below ground level. The reasons for this are: 1. Fuel gas tends to follow the path of least resistance, which often is the trench in which the gas piping is laid. 2. Heaving soil may have an adverse effect on a caulked sleeve, causing it to loosen and permit any leaking gas to penetrate the building. By allowing gas piping to enter the building only above grade, the potential for leaking gas from a below-grade gas leak to enter the building by migrating through the entry of the piping void in the foundation wall will be eliminated.

92 Part I: Construction 1.10 Installer Training The manufacturer shall establish and maintain an installer training program and a database of installers who have completed the manufacturer's training requirements. An identification card shall be supplied to each installer who has completed the manufacturer's training requirements, and a record of the installer s contact data shall be maintained in the database. The identification card shall include the following information: CSST manufacturer s name and telephone number CSST product(s)/brand(s) covered by training Unique serial number for the identification card (recorded in database) Installer s name and the date of training or card issuance (recorded in database), and Statement that the named installer has completed the manufacturer s training program to install [insert manufacturer s name or brand] CSST RATIONALE: Training of installers is a manufacturer-based requirement, and therefore it transcends any other installer qualifications imposed by the country, state or local jurisdiction such as licensing, education or apprenticeship. CSST systems have unique features, including fitting attachments proprietary to each manufacturer, which are not interchangeable between brands. The requirement has been modified and moved to the body of the Standard and not in Exhibit B since training is required whether the installer is US-based or Canada-based. The training requirement was modified to create auditable action items for the certifying agency such as a database and a training program. 1.2 Materials For tubing which includes a nonmetallic coating or covering, the coating shall comply with the international color designation of yellow. A jacket or covering applied to the tubing shall be either yellow or black, and marked in a contrasting color. RATIONALE: To recognize alternate color jackets that are currently available in the marketplace consistent with other commercial gas-piping products. Part II: Performance 2.15 Arc Resistant Jacket or Covering System (Optional) General

93 Unless otherwise specified, all testing shall be performed in accordance with the general requirements of ANSI LC-1 and as stipulated in Part II Performance Tubing which has an arc resistant jacket or covering system as an alternate direct-bonding means (henceforth referred to as the "jacket") shall comply with the following tests Unless otherwise specified, the jacket shall comply with the following tests with the tubing, jacket, and fitting(s) assembled as a final installation and in accordance with the manufacturer's instructions Testing shall be performed on samples of tubing sizes ½-inch and 1-inch in diameter. Each test sample shall be at least three feet in length or as specified within the Method of Test Resistance of Jacket Material To Extreme Environment(s) Resistance of Jacket Assembly to Extreme Temperature Cycles Test specimens of the jacket material shall be prepared (based on the fabrication technique used to apply the jacket) and subjected to exposure to low temperature in accordance and compliance with ASTM D for Brittleness Temperature of Plastics and Elastomers by Impact. The manufacturer shall present a test report from an accredited testing laboratory to the listing agency including a statement on the minimum embrittlement temperature Resistance of Jacket Assembly to Corrosion The tubing, jacket and fitting assembly (assembled per the manufacturer s instructions) shall be subjected to the Standard Practice for Operating Salt Spray (Fog) Apparatus, ASTM B117-97, for not less than 96 hours without evidence of pitting, flaking, cracking or signs of corrosive attack in accordance with Part 1.2.5, and then shall be subsequently subjected to and pass Part Electrical Tests. Two samples of each size shall be prepared and subjected to the prescribed test. Products that do not incorporate a metallic layer or component as part of the jacket are not required to be tested to The manufacturer shall present a test report from an accredited testing laboratory to the listing agency and deliver the test samples to the laboratory performing the Electrical Tests. CSA Group - 2 -

94 Electrical Tests Robustness Against Arcing (Indirect Lightning) Tubing, jacket and fitting assemblies shall withstand electrical arcing, in accordance with the following method of test without perforation of the tubing and without leakage in excess of that specified in Part 2.2, Leakage. The test samples subjected to the salt spray exposure (if applicable) in Part Resistance of Jacket Assembly to Corrosion shall be used in the testing. Other samples shall be used if no samples are required to be subjected to salt spray exposure in Part Testing shall be performed by an accredited lightning testing laboratory acceptable to the listing agency. Method of Test For arc robustness determination, a electrical waveform (Current vs. Time) shall be utilized. (NOTE: Additional testing intended to address a wider range of possible transient sources and behaviors may be considered, but this has not been included in the prescribed Method of Test.) The waveform is defined by its rise-time to peak current and fall-time to 50 percent of peak amplitude. The selected waveform is 10µs x1000µs. Generator Calibration: An electrical test generator and appropriate measurement equipment shall be assembled to generate the waveform under consideration and to record generator output. (See Figure 1 for schematic.) The generator assembly shall utilize an electrode of ¼ in diameter attached to the output of the generator (i.e. live terminal). The test sample is grounded to the generator with a minimum AWG 6 copper conductor or equivalently sized braided strap. The test sample shall be supported in such a manner to prevent arcing or conduction from the test sample to adjacent equipment. A length of copper pipe is installed as the test sample, with a 1/8 in gap between the copper pipe and the generator electrode. The generator is charged to the desired level, and discharged through the electrode to the copper pipe (via an arc) and then to ground. Arc attachment to the tubing shall be verified. Arc attachment to nearby equipment or to end connections on the copper tubing invalidates this test run. The recorded generator output is verified against the desired waveform. Adjustments to the generator assembly are made and re-tested until the generator output matches the desired waveform output. Testing: The test sample is installed with the electrode placed over a straight portion of the sample, with a 1/8 in gap between the exterior of the jacket and the generator electrode. (Refer to Figure 1) The generator is charged to the desired level, and discharged through the electrode to the test assembly (via arc) and to ground. Arc attachment to CSA Group - 3 -

95 the tubing shall be verified. Arc attachment to nearby equipment or to end connections on the tubing invalidates this test run. Figure 1 Experimental Set-Up for Arc Resistance Test The recorded generator output is verified against the desired waveform. Peak current and coulombs transferred (the integral of the waveform) are recorded. The jacket is removed from the site of the arc termination allowing a visual inspection of the exposed tubing. The tubing must show no puncture of the stainless steel tubing. The test assembly must withstand a minimum of 4.5 Coulombs without leakage as defined by Part 2.2 Leakage Resistance to Installation Damage Tubing and jacket assemblies shall withstand damage from friction/wear in a simulated drag-zone installation without excessive damage to the jacket in accordance with the following method of test. Method of Test Three individual simulated joists/ studs (spaced 16-inches on-center) made from solid, dimensional lumber (2 x 6 min) are mounted in a framework as shown in Figure 2. The drag-zone apparatus can be table or floor mounted. A routing hole shall be drilled through each joist in a 3-in off-set pattern as shown in Figure 2. Each routing hole shall be ½-inch greater in diameter than the outside diameter of the jacketed tubing specimen. The routing holes shall be drilled with a standard hole-cutter/drill bit and no post-drilling cleaning or dressing of the holes shall be permitted. No metal fasteners CSA Group - 4 -

96 shall be installed within the drag zone. The test apparatus shall be solidly secured to the table/floor to prevent movement or shaking of the assembly during the pull tests. Two test specimens of each size, each consisting of a 15-ft length of tubing, shall be prepared. Each test specimen shall be snaked through the three offset holes before starting the test. The length of tubing is then pulled, by hand, through the drag zone until the end of the test specimen exits the last member. The rate of pull should be approximately 1 to 2 feet per second. Figure 2 Set-Up for Tubing Wear Test Upon completion of the pull test, the tubing and jacket shall be inspected for physical damage. Any tearing or ripping of the jacket exposing the underlying stainless steel tubing indicates non-compliance with this requirement. RATIONALE: Some CSST products have been developed that use a coating or covering system to provide an alternate means of direct-bonding. If such a coating is provided as part of the CSST system, the added tests address the durability and integrity of the coating. The performance requirements and acceptance criteria represent minimally acceptable values that have been developed by independent sources. The International Code Council Evaluation Services have developed such testing methods and listing criteria (LC1024 Listing Criteria for CSST Utilizing a Protective Jacket) that are being used to list current products. The proposed test methods are similar to testing widely used in the lightning analysis industry and have been recommended by independent lightning experts. Exhibit B: Items Unique to United States CSA Group - 5 -

97 B.1 The installation shall be done by a qualified installer, who has passed the manufacturer s certification/training program. RATIONALE: Training of installers is a manufacturer-based requirement, and therefore it transcends any other installer qualifications imposed by the country, state or local jurisdiction such as licensing, education or apprenticeship. CSST systems have unique features, including fitting attachments proprietary to each manufacturer, which are not interchangeable between brands. The requirement has been modified and moved to the body of the Standard and not in Exhibit B since training is required whether the installer is US-based or Canada-based. The training requirement was modified to create auditable action items for the certifying agency such as a database and a training program. CSA Group - 6 -

98 National Fire Protection Association Report Page 48 of 95 5/13/2013 Comment Related to PI 44 The use of a CSST product with a protective, arc-resistant jacket is an alternate method of protection against electrical arcing damage caused by high voltage transient events such as a nearby lightning strike. An arcresistant jacket does not rely on direct bonding to the grounding electrode system to provide a low-impedance pathway to reduce or eliminate damage from electrical arcing. Instead, the protective jacket acts as a resistor and is designed to locally absorb and dissipate the arcing energy over a short length of the jacket. The jacket, in essence, disrupts the focus of the arc and reduces the energy level below the threshold value that can cause a perforation of the tubing wall. This dynamic action is equally effective compared to the current CSST bonding method regardless of the bonding conductor size or length. The protection against arcing is provided uniformly throughout the piping system. Protection is not affected by close proximity to other metallic systems that may not be similarly bonded, and is not dependent on the quality of the grounding electrode or its connection to ground. Although arc-resistant CSST products are tested and listed in accordance with an ICC Listing Criteria (LC1024 or LC1027), the over-riding ANSI LC-l consensus standard is in the [mal stages of being updated to include new performance requirements for arcresistant jackets. Addendum C to ANSI LC-l (attached) includes performance tests to demonstrate the viability of these jackets to resist arcing damage, withstand exposure to extreme environmental conditions and to verify jacket toughness. The testing criteria are based on existing test methods from other certifying organizations/methods which have undergone public vetting with no objections. The ANSI certification process is nearly complete and is expected before the end of PowerCET was requested to re-run the same piping system simulations utilized in the GTI Phase II research project to compare the effectiveness of the arc-resistant CSST against yellow CSST as well as copper tubing. All appropriate adjustments were made based on the electrical properties of arc-resistant jacket and copper tubing. The results from these new simulations indicate that arcresistant CSST is far less likely to be damaged from a lightning induced arc compared to yellow CSST and copper tubing. The attached figure depicts the arc-charge and duration curves for these materials, and supports approval of the proposal to permit these arc-resistant CSST products as an alternative method to direct bonding. CSST with arc-resistant jacket has been commercially installed since 2004, and at the present time, three different (black-jacketed) products are commercially available. Currently, at least 12 states permit the installation of the arc-resistant CSST without the need for additional bonding. Given that both conventional (yellow) and advanced (black) CSST products will continue to be commercially available, both methods of electrical protection of CSST systems should be recognized and permitted within the Code.

99 National Fire Protection Association Report Page 50 of 95 5/13/2013 Public Comment No. 20-NFPA [ Sections , ] Sections , Test pressure shall be measured with a manometer or with a pressure measuring device designed and calibrated to read, record, or indicate a pressure loss due to leakage during the pressure test period. The source of pressure shall be isolated before the pressure tests are made. Mechanical gauges used to measure test pressures shall have a range such that the highest end of the scale is not greater than 5 times the test pressure The test pressure to be used shall be no less than times the proposed maximum working pressure, but not less than 3 psi (20 kpa), irrespective of design pressure. Where the test pressure exceeds 125 psi (862 kpa), the test pressure shall not exceed a value that produces a hoop stress in the piping greater than 50 percent of the specified minimum yield strength of the pipe Low pressure gas piping systems and/or a section of piping, shall be retested where the existing delivery pressure is increased above 2 psig Medium pressure gas piping systems shall be retested in accordance with section when the existing delivery pressure is increased. Statement of Problem and Substantiation for Public Comment Larger commercial and industrial customers many times request the serving gas utilitiy to increase delivery pressures to their piping systems to accommodate additional equipement and increased demand. Increasing the line pressure is an economical alternative to prevent the need to re-size (increase) existing houselines and significant cost to owners. Currently the NFGC is slient regarnding this issue of what to do customers request an increase of pressure to existing gas houselines...guidance is needed.

100 National Fire Protection Association Report Page 52 of 95 5/13/2013 Public Comment No. 24-NFPA [ Section No ] * Existing Appliances. Where building envelope components of existing buildings are replaced or altered, the existing appliance installations shall be inspected to verify compliance with the provisions of Section 9.3 and Chapter 12. Where the appliance installations do not comply with Section 9.3 and Chapter 12, they shall be altered as necessary to be in compliance with such. Statement of Problem and Substantiation for Public Comment There are multiple problems with this proposed language. First of all, it is in the wrong code. The people who would need to see this section won't be looking in the NFGC if they aren't doing work on fuel gas systems or appliances in the first place. This language would need to be in the building code and point to this code. The requirements of the proposed section is also extremely restrictive. It would require appliance installations to be inspected and brought up to current code even if minimal work is done on the exterior of the home, because there is no minimum amount of work before this requirement applies. This could lead to a homeowner being required to have costly work done to update the appliance venting and adding combustion air openings when a few siding boards are replaced or an insert unit is installed in a single window. Finally, since the term 'building envelope' is not defined, it could mean anything from the air/thermal barrier to the weather resistive barrier--which could include the roof over an unconditioned attic. This could lead to a homeowner being required to update the appliance venting and adding combustion air openings when the shingles are replaced.

101 National Fire Protection Association Report Page 53 of 95 5/13/2013 Public Comment No. 40-NFPA [ Section No ] * Existing Appliances. Where building envelope components of existing buildings are replaced an existing appliance is located within the conditioned space of an existing building envelope and where a building envelope component is replaced or altered, the existing the appliance installations shall be inspected to verify compliance with the provisions of Section 9.3 and Chapter 12. Where the appliance installations do not comply with Section 9.3 and Chapter 12, they shall be altered as necessary to be in compliance with such. Exception: Roofing material replacements. Statement of Problem and Substantiation for Public Comment The proposed requirement may be too broad. For example, a simple reroofing project that would not impact combustion air supplies would unnecessarily trigger the combustion air and venting checks. The new revised text and exception would permit certain building envelope changes without triggering the verification.

102 National Fire Protection Association Report Page 54 of 95 5/13/2013 Public Comment No. 46-NFPA [ Section No ] * Existing Appliances. Where building envelope components of existing buildings are replaced or altered, the existing appliance installations shall be inspected to verify compliance with the provisions of Section 9.3 and Chapter 12. Where the appliance installations do not comply with Section 9.3 and Chapter 12, they shall be altered as necessary to be in compliance with such. Statement of Problem and Substantiation for Public Comment While the intent of the change has merit, it is unenforceable. Changes to the building envelope components are not done be gas installers, and not permitted by a gas official. If new windows are installed in a home, how will the window installer know that the air for combustion must be checked and that the venting system may have to be modified.

Laboratory equipment burners (Bunsen ) burners used, Teclu, Meker, or similar) with inputs of 12,000 btu or less, used in laboratories and educational facilities shall be permitted to be connected to the gas supply by an unlisted hose. File Name Description Approved NFGC_Comment_9.6.3.pdf Original Comment Statement of Problem and Substantiation for Public Comment The connection method described in Section 9.6.1(7) leaves room for interpretation even though it cites Section In-shot burners, used in some space heating appliances could be considered Injection burners. This provision is not intended to allow unlisted hose to be used to connect gas-fired equipment to the gas supply. The suggested limit to the input capacity is an arbitrary value, but at some level of energy input, even in a laboratory, the fuel connection to the burner should be more substantial than a rubber hose. Without a limit burners with inputs in the tens or hundreds of thousands could be connected with a rubber hose. Bunsen is but one type of burner utilized in laboratories.

111 National Fire Protection Association Report Page 63 of 95 5/13/2013 In the proposed version, NFPA 54 skirts its purpose and responsibility for providing clear guidance to appliance and venting manufacturers as well as code inforcement officials in regards to venting an ever growing portion of the residential heating and warm water preparation market. Responsibility as well as liability for "venting" is solely delegated to the appliance manufacturer. While appliance manufacturers do extensive performance testing on their equipment and in conjunction, some safety testing on the "plastic piping used for venting" NFPA 54, ), many safety tests required for any other venting material or venting system are not performed. Installation intructions provided for plastic pipe used for venting can and do vary from one appliance manufacturer to the other. Any venting system listed to UL 1738, the established standard for "Venting Systems for Gas Burning Appliances" however, delivers a product to the appliance manufacturer, the trade and the end user that has been thoroughly safety tested, has vetted and approved installation instructions and is labelled for easy identification. The responsibility for delivering a safe and reliable venting system to the industry is placed with the venting manufacturer, where it belongs. In this context, and need to be elininated from the current proposed version of NFPA 54.

114 National Fire Protection Association Report Page 66 of 95 5/13/2013 It is paramount for any equipment used in all types of construction to be designed, constructed, tested and listed for said use. Safety is at the crux of this request. Currently, venting of category IV appliances only requires basic operational testing of said venting material. Generally these materials being approved by the manufacturer are PVC, CPVC, Polypropylene and Stainless Steel. PVC and CPVC have never been designed nor tested as combustion gas vents. Furthermore, the largest manufacturers of PVC and CPVC specifically denote that their product has never been tested or designed as a combustion gas vent and vehemently discourage their use as such via official statements. Essentially, the current wording and structuring of sections and allow for this use of unlisted combustion gas vent material. Through the above proposed corrective action the committee can close a glaring loophole in the National Fuel Gas Code which can jeopardize the safety of any individuals within a contained structure in which a category IV appliance is running. We have safety standards for construction materials covering from residential, commercial, industrial, and institutional buildings. These standards have been designed and crafted to ensure that the integrity of products will not fail during all aspects of construction and use. Why, then, would we not apply the same safety precautions in testing, listing and use to venting of combustion gasses? It is incomprehensible to imagine the allowable use of a specific material as a combustion gas vent when the respective manufacturer of the material does not recommend, test or approve of its use as a combustion gas vent. If a device carrying odorless, toxic gasses does not need to be listed to a safety standard, then why have safety standards or codes at all?

129 National Fire Protection Association Report Page 79 of 95 5/13/2013 Public Comment No. 18-NFPA [ Section No. B.4.1 ] B.4.1 The Longest Length Method. This sizing method is conservative in its approach by applying the maximum operating conditions in the system as the norm for the system and by setting the length of pipe used to size any given part of the piping system to the maximum value. To determine the size of each section of gas piping in a system within the range of the capacity tables, proceed as follows (also see sample calculations included in this annex): (1) Divide the piping system into appropriate segments consistent with the presence of tees, branch lines, and main runs. For each segment, determine the gas load (assuming all appliances operate simultaneously) and its overall length. An allowance (in equivalent length of pipe) as determined from Table B.3.2 should be considered for piping segments that include four or more fittings. (2) Determine the gas demand of each appliance to be attached to the piping system. Where Table 6.2(a) through Table 6.2(x) are to be used to select the piping size, calculate the gas demand in terms of cubic feet per hour for each piping system outlet. Where Table 6.3(a) through Table 6.3(m) are to be used to select the piping size, calculate the gas demand in terms of thousands of Btu per hour for each piping system outlet. (3) Where the piping system is for use with other than undiluted LP-Gases, determine the design system pressure, the allowable loss in pressure (pressure drop), and specific gravity of the gas to be used in the piping system. (4) Determine the length of piping from the point of delivery to the most remote outlet in the building/piping system. (5) In the appropriate capacity table, select the row showing the measured length or the next longer length if the table does not give the exact length. This length is the only length used in determining the size of any section of gas piping. If the gravity factor is to be applied, the values in the selected row of the table are multiplied by the appropriate multiplier from Table B.3.4. (6) Use this horizontal row to locate ALL gas demand figures for this particular system of piping. (7) Starting at the most remote outlet, find the gas demand for that outlet in the horizontal row just selected. If the exact figure of demand is not shown, choose the next larger figure left in the row. (8) Opposite this demand figure, in the first row at the top, the correct size of gas piping will be found. (9) Proceed in a similar manner for each outlet and each section of gas piping. For each section of piping, determine the total gas demand supplied by that section.

130 National Fire Protection Association Report Page 80 of 95 5/13/2013 When a large number of piping components (such as elbows, tees, and valves) are installed in a pipe run, additional pressure loss can be accounted for by the use of equivalent lengths. Pressure loss across any piping component can be equated to the pressure drop through a length of pipe. The equivalent length of a combination of only four elbows/tees can result in a jump to the next larger length row, resulting in a significant reduction in capacity. The equivalent lengths in feet shown in Table B.3.2 have been computed on a basis that the inside diameter corresponds to that of Schedule 40 (standard weight) steel pipe, which is close enough for most purposes involving other schedules of pipe. Where a more specific solution for equivalent length is desired, this can be made by multiplying the actual inside diameter of the pipe in inches by n/12, or the actual inside diameter in feet by n. N can be read from the table heading. The equivalent length values can be used with reasonable accuracy for copper or brass copper alloy fittings and bends, although the resistance per foot of copper or brass pipe is less than that of steel. For copper or brass copper alloy valves, however, the equivalent length of pipe should be taken as 45 percent longer than the values in the table, which are for steel pipe.

131 National Fire Protection Association Report Page 81 of 95 5/13/2013 Public Comment No. 70-NFPA [ Section No. C.3 ] C.3 Leak Check Not Using a Meter. This test can be done using one of the following methods: (1) For Any Gas System. To an appropriate checkpoint, attach a manometer or pressure gauge between the inlet to the piping system and the first regulator in the piping system, momentarily turn on the gas supply, and observe the gauging device for pressure drop with the gas supply shut off. No discernible drop in pressure should occur during a period of 3 minutes. (2) For Gas Systems Using Undiluted LP-Gas System Preparation for Propane. A leak check performed on an LP-Gas system being placed back in service can be performed by using one of the following methods: (a) (b) By inserting Insert a pressure gauge between the container gas shutoff valve and the first-stage regulator or integral two-stage regulator in the system, admitting full container pressure to the system and then closing the container shutoff valve. Enough gas should then be released from the system to lower the pressure gauge reading by 10 psi (69 kpa). The system should then be allowed to stand for 3 minutes without showing an increase or a decrease in the pressure gauge reading. Insert a gauge/regulator test assembly between the container gas shutoff valve and first-stage regulator or integral two-stage regulator in the system. If a gauge/regulator test assembly with an inches water column gauge is inserted, follow the test requirements in (c) below; if a gauge/ regulator test assembly with a 30 psi gauge is inserted follow the test requirements in (d). (3) For systems with an integral two-stage, one or more secondstage, or one or more line pressure regulators serving appliances that receive gas at pressures of 1 2 psi (3.5 kpa) or less, by inserting insert a water manometer or pressure inches water column gauge into the system downstream of the final system stage regulator, pressurizing the system with either fuel gas or air to a test pressure of 9 in. w.c. ± 1 2 in. w.c. (2.2 kpa ± 0.1 kpa), and observing the device for a pressure change. If fuel gas is used as a pressure source, it is necessary to pressurize the system to full operating pressure, close the container service valve, and then release enough gas from the system through a range burner valve or other suitable means to drop the system pressure to 9 in. w.c. ± 1 2 in. w.c. (2.2 kpa ± 0.1 kpa). This ensures that all regulators in the system upstream of the test point are unlocked and that a leak anywhere in the system is communicated to the gauging device. The gauging device should indicate no loss or gain of pressure for a period of 3 minutes.

132 National Fire Protection Association Report Page 82 of 95 5/13/2013 (4) By inserting a When testing a system that has a first-stage regulator, or an integral two-stage regulator, insert a 30 psi (207 kpa) pressure gauge on the downstream side of the first-stage regulator or at the intermediate pressure tap of an integral twostage regulator, admitting normal operating pressure to the system and then closing the container valve. Enough pressure gas should be released from the system to lower the pressure gauge reading by 5 a minimum of 2 psi ( kpa) so that the first-stage regulator is unlocked. The system should be allowed to stand for 3 minutes without showing an increase or a decrease in pressure gauge reading. (5) Insert a gauge/regulator test assembly on the downstream side of the first stage regulator or at the intermediate pressure tap of an integral two stage regulator. If a gauge/regulator test assembly, with an inches water column gauge is inserted, follow the test requirements in (c)above; if a gauge/regulator test assembly with a 30 psi gauge is inserted follow the test requirements in (d) above.

133 National Fire Protection Association Report Page 83 of 95 5/13/2013 In C.3 (2) (b) and (e), the proposal incorporates language to cover leak checking of systems utilizing a gauge/regulator test assembly with a low pressure regulator and an inches water column gauge or a test assembly with a high pressure regulator and a 30 psi gauge as part of the test assembly. The proposal refers the reader to the type of test that should be conducted when utilizing whichever type of test assembly is installed. The addition of gauge/regulator test assemblies in C.3(2)(b) and (e) is to recognize new tools that are available and being used by bobtail drivers and service personnel. The gauge/regulator test assembly incorporates a pressure regulator that is part of the test assembly and is at the inlet to the pressure gauge. The regulator controls the pressure to the gauge when the tank service valve is opened to pressurize the system. With the system pressurized, the service valve is closed and gas pressure is released from the test assembly, dropping the gauge reading and unlocking the test assembly regulator as well as any regulators upstream of the test connection. After this is accomplished, the test gauge will now read the system pressure, allowing the leak check to be conducted. In C.3 (2) (c), there are systems that utilize a number of second-stage regulators supplied from one first-stage regulator and 2 psi systems may use a number of line pressure regulators supplied from one first-stage and a 2 psi regulator. The requirement in the test protocol is to insure regulators upstream of the selected checkpoint are unlocked. If there are piping systems with regulators in parallel within the piping system and there is a leak in the parallel line, the new provisions would insure that the parallel regulator would not lockup and the leak would be detected. If there is no leak in the parallel line, the parallel regulator would lockup as expected and that is acceptable. This change specifically addresses the need for a clarification of the testing required when there is more than one second stage regulator and the procedure to ensure the regulators are unlocked during the test. Paragraph C.3 (2) (d) adds testing information for 5 psi first-stage regulators which are utilized in many of the northern States where container pressures can drop to 10 psi. The 2 psi minimum pressure reduction will insure that the first stage regulator, 5 or 10 psi outlet setting is unlocked when the leak check is performed.

In an evaluation of an existing appliance such as a water heater it is unlikely that the flue will be cold. Additionally, it is likely that such appliances will often have on-times of less than 5 minutes in a cycle. Field experience suggests that appliances that spill after 2 minutes are likely to spill after 5 minutes. The 2 minute requirement is therefore more consistent with existing appliance applications and saves time without substantially impacting the failure rate.

An example would be a large kitchen exhaust in a home in which the combustion appliance is located in a basement, and in which the door between the first floor and the basement is tight-fitting. When the door is closed the kitchen exhaust may not be able to pull much air from the basement, but when it is open it is then able to pull excessive air from the basement and cause spillage. This must be evaluated in order to cover the range of common causes of spillage. This must be done separately from turning on all fans which exhaust air because the position of this door may cause either negative or positive pressure impacts.

140 National Fire Protection Association Report Page 94 of 95 5/13/2013 Public Comment No. 42-NFPA [ Section No. G.1 ] G.1 General. The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in a safe condition for continuing use. This procedure is intended for central furnace and boiler installations, and might not be applicable to all installations. This procedure should be performed prior to any attempt to modify the appliance or the installation. If it is determined a condition that could result in unsafe operation exists, shut off the appliance and advise the owner of the unsafe condition. The following steps should be followed in making the safety inspection: (1) Conduct a test for gas leakage. (2) Visually inspect the venting system for proper size and horizontal pitch, and determine that there is no blockage, restriction, leakage, corrosion, or other deficiencies that could cause an unsafe condition. (3) Shut off all gas to the appliance, and shut off any other fuel gas burning appliance within the same room. Use the shutoff valve in the supply line to each appliance. (4) Inspect burners and crossovers for blockage and corrosion. (5) Furnace Installations: Inspect the heat exchanger for cracks, openings, or excessive corrosion. (6) Boiler Installations: Inspect for evidence of water or combustion product leaks. (7) Close all building doors and windows and all doors between the space in which the appliance is located and other spaces of the building that can be closed. Turn on any clothes dryers. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers. If, after completing Steps 8 through 13, it is believed sufficient combustion air is not available, refer to Section 9.3 of this code. (8) Place the appliance being inspected in operation. Follow the lighting instructions. Adjust the thermostat so the appliance operates continuously. (9) Determine that the pilot, where provided, is burning properly and that the main burner ignition is satisfactory by interrupting and re-establishing the electrical supply to the appliance in any convenient manner. If the appliance is equipped with a continuous pilot, test all pilot safety devices to determine whether it is operating properly by extinguishing the pilot when the main burner is off and determining, after 3 minutes, that the main burner gas does not flow upon a call for heat. If the appliance is not provided with a pilot, test for proper operation of the ignition system in accordance with the appliance manufacturer s lighting and operating instructions. (10) Visually determine that the main burner gas is burning properly (i.e., no floating, lifting, or flashback). Adjust the primary air shutters as required. If the appliance is equipped with high and low flame controls or flame modulation, check for proper main burner operation at low flame. (11) Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle or smoke.

141 National Fire Protection Association Report Page 95 of 95 5/13/2013 (12) Turn on all other fuel gas burning appliances within the same room so they operate at their full inputs. Follow lighting instructions for each appliance. (13) Repeat Steps 10 and 11 on the appliance being inspected. (14) Return doors, windows, exhaust fans, fireplace dampers, and any other fuel gas burning appliance to their previous conditions of use. (15) Furnace Installations: Check both the limit control and the fan control for proper operation. Limit control operation can be checked by blocking the circulating air inlet or temporarily disconnecting the electrical supply to the blower motor and determining that the limit control acts to shut off the main burner gas. (16) Boiler Installations: Verify that the water pumps are in operating condition. Test low-water cutoffs, automatic feed controls, pressure and temperature limit controls, and relief valves in accordance with the manufacturer s recommendations to determine that they are in operating condition.

142 AGA supports the rewrite of Annex G and offers the following revisions (highlighted in yellow). Annex G Recommended Procedure for Safety Inspection of an Existing Appliance Installation This annex is not a part of the requirements of this code but is included for informational purposes only. G.1 General. The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in a safe condition for continued use. Where a gas supplier performs an inspection their written procedures should be followed. G.1.1 Application. This procedure is intended for existing residential installations of a furnace, boiler, room heater, water heater, cooking appliance, fireplace appliance and clothes dryer. This procedure should be performed prior to any attempt to modify the appliance, the installation, and building envelope. G.1.2 Weatherization Programs. Before a building envelope is to be modified as part of a weatherization program, the existing appliance installation should be inspected in accordance with these procedures. After all unsafe conditions are repaired, and immediately after the weatherization is complete, the appliance inspections in G.5.2 are to be repeated. G.1.3 Inspection Procedure. The safety of the building occupant and inspector are to be determined as the first step as described in G.2. Only after the ambient environment is found to be safe should inspections of gas piping and appliances be undertaken. It is recommended that all inspections described in G.3, G.4, and G.6, where the appliance is in the off mode, be completed and any unsafe conditions repaired or corrected before proceeding continuing with inspections of an operating appliance described in G.5 and G.6. G.1.4 Manufacturer Instructions. Where available, the manufacturer s installation and operating instructions for the installed appliances should be used as part of these inspection procedures to determine if it is installed correctly and is operating properly. G.1.5 Detectors Instruments. The inspection procedures include measuring for fuel gas and carbon monoxide (CO) and will require the use of combustible gas detector (CGD) and CO detector. It is recommended that both types of detectors be listed. Prior to any inspection the detectors should be calibrated or tested in accordance with the manufacturer s instructions. In addition, it is recommended that the detectors have the following minimum specifications. a. Gas Detector: The CGD should be capable of indicating the presence of the type of fuel gas for which it is to be used (e.g. natural gas or propane). The combustible gas detector should be capable of the following: PPM: Numeric display with a parts per million (ppm) scale from 1 percent to 900 ppm in 1 ppm increments. LEL: Numeric display with a percent lower explosible limit (% LEL) scale from 0 percent to 100 percent in 1 percent increments. Audio: An audio sound feature to locate leaks. b. CO Detector: The CO detector should be capable of the following functions and have a numeric display scale as follows: PPM: For measuring ambient room and appliance emissions a display scale in parts per million (ppm) from 0 to 1,000 ppm in 1 ppm increments. Alarm: A sound alarm function where hazardous levels of ambient CO is found (see G.2 for alarm levels) Air Free: Capable of converting CO measurements to an air free level in ppm. G.2 Occupant and Inspector Safety. The inspector prior to entering a building should have both a combustible gas detector (CGD) and CO detector turned on, calibrated, and operating. Immediately upon entering the building, a sample of the ambient atmosphere should be taken. Based on CGD and CO detector readings the inspector should take the following actions: (1) The CO detector indicates a carbon monoxide level of 70 ppm or greater 1. The inspector should immediately notify the occupant of the need for themselves and any building occupant to evacuate; the inspector shall immediately evacuate and call 911. (2) Where the CO detector indicates a reading between 30 ppm and 70 ppm 1. The inspector should advise the occupant that high CO levels have been found and recommend that all possible sources of CO should be turned off immediately and windows and doors opened. Where it appears that the source of CO is a permanently installed appliance, advise the occupant to keep the appliance off and have the appliance serviced by a qualified servicing agent. 1 U.S. Consumer Product Safety Commission, Responding to Residential Carbon Monoxide Incidents, Guidelines For Fire and Other Emergency Response Personnel, Approved 7/23/02

143 (3) Where CO detector indicates CO below 30 ppm 1 the inspection can proceed continue. (4) The CGD indicates a combustible gas level of 20% % LEL or greater. The inspector should immediately notify the occupant of the need for themselves and any building occupant to evacuate; the inspector shall immediately evacuate and call 911. (5) The CGD indicates a combustible gas level below 20% LEL the inspection can proceed continue. If during the inspection process it is determined a condition exists that could result in unsafe appliance operation, shut off the appliance and advise the owner of the unsafe condition. Where a gas leak is found that may result in an unsafe condition, advise the owner of the unsafe condition and call the gas supplier to turn off the gas supply. The inspector should not continue a safety inspection on an operating appliance, venting system, and piping system until repairs have been made. G.3 Gas Piping and Connection Inspections (1) Leak Checks. Conduct a test for gas leakage using either a non-corrosive leak detection solution or a CGD confirmed with a leak detection solution. The preferred method for leak checking is by use of gas leak detection solution applied to all joints. This method provides a reliable visual indication of significant leaks. The use of a CGD in its audio sensing mode can quickly locate suspect leaks but may be overly sensitive indicating insignificant and false leaks. All suspect leaks found through the use of a CGD should be confirmed using a leak detection solution. Where gas leakage is confirmed, the owner should be notified that repairs must be made. The inspection should include the following components: a. All gas piping fittings located within the appliance space. b. Appliance connector fittings. c. Appliance gas valve/regulator housing and connections. (2) Appliance Connector. Verify that the appliance connection type is compliant with Section 9.6 of the National Fuel Gas Code. Inspect flexible appliance connections to determine if they are free of cracks, corrosion and signs of damage. Verify that there are no uncoated brass connectors. Where connectors are determined to be unsafe or where an uncoated brass connector is found, the appliance shutoff valve should be placed in the off position and the owner notified that the connector must be replaced. (3) Piping Suport Support. Inspect piping to determine that it is adequately supported, that there is no undue stress on the piping, and if there are any improperly capped pipe openings. (4) Bonding. Verify that the electrical bonding of gas piping is compliant with Section 7.13 of the National Fuel Gas Code. G.4 Inspections to be preformed performed with the Appliance Not Operating. The following safety inspection procedures are performed on appliances that are not operating. These inspections are applicable to all appliance installations. (1) Preparing for Inspection. Shut off all gas and electrical power to the appliances located in the same room being inspected. For gas supply use the shutoff valve in the supply line or at the manifold serving each appliance. For electrical power place the circuit breaker in the off position or remove the fuse that serves each appliance. A lock type device or tag should be installed on each gas shutoff valve and at the electrical panel to indicate that the service has been shut off for inspection purposes. (2) Vent System Size and Installation. Verify that the existing venting system size and installation is are compliant with Chapters of the National Fuel Gas Code. The size and installation of venting systems for other than natural draft and ccategory I appliances should be in compliance with the manufacturer s installation instructions. Inspect the venting system to determine that it is free of blockage, restriction, leakage, corrosion, and other deficiencies that could cause an unsafe condition. Inspect masonry chimneys to determine if they are lined. Inspect plastic venting systems to determine that it is free of sagging and it is sloped in an upward direction to the outdoor vent termination. (3) Combustion Air Supply. Inspect provisions for combustion air as follows: a. Non-Direct Vent Appliances. Determine that non-direct vent appliance installations are compliant with the combustion air requirements in Section 9.3 of the National Fuel Gas Code. Inspect any interior and exterior combustion air openings and any connected combustion air ducts to determine that there is no blockage, restriction, corrosion or damage. Inspect to determine if horizontal combustion air ducts are sloped in an upward direction towards the air supply source. b. Direct Vent Appliances. Verify that the combustion air supply ducts and pipes are securely fastened to direct vent appliance and determine that there is are no separations, blockage, restriction, corrosion or other damage. Determine that the combustion air source is located in the outdoors or to areas that freely communicate to the outdoors.

144 c. Unvented Appliances. Verify that the total input of all unvented room heaters and gas-fired refrigerators installed in the same room or rooms that freely communicate with each other does not exceed 20 Btu/hr/ft3. (4) Flooded Appliances. Inspect the appliance for signs that the appliance may have been damaged by flooding. Signs of flooding include a visible water submerge line on the appliance housing, excessive surface or component rust, deposited debris on internal components, and mildewlike odor. Inform the owner that all flood-damaged plumbing, heating, cooling and electrical appliances and related systems should be replaced. (5) Flammable Vapors. Inspect the room/space where the appliance is installed to determine if the area is free of the storage of gasoline or any flammable products such as oil-based solvents, varnishes or adhesives. Where the appliance is installed where flammable products will be stored or used, such as a garage, verify that the appliances burner is a minimum of 18 above the floor unless the appliance is listed as flammable vapor ignition resistant. (6) Clearances to Combustibles. Inspect the immediate location where the appliance is installed to determine if the area is free of rags, paper or other combustibles. Verify that the appliance and venting system is compliant with clearances to combustible building components in Section of the National Fuel Gas Code. (7) Appliance Components. Inspect internal components by removing access panels or other components for the following: a. Inspect burners and crossovers for blockage and corrosion. The presence of soot, debris, and signs of excessive heating may indicate incomplete combustion due to blockage or improper burner adjustments. c. Metallic and non-metallic hoses for signs of cracks, splitting, corrosion, and lose connections. d. Signs of improper or incomplete repairs e. Modifications that override controls and safety systems f. Electrical wiring for loose connections; cracks, missing or worn electrical insulation; and indications of excessive heat or electrical shorting. Appliances requiring an external electrical supply should be inspected for proper electrical connection in accordance with the National Electric Code. (8) Placing Appliances Back in Operation. Return all inspected appliances and systems to their preexisting state by reinstalling any removed access panels and components. Turn on the gas supply and electricity to each appliance found in safe condition. Proceed to the operating inspections in G.5 through G.6. G.5 Inspections to be performed with the Appliance Operating. The following safety inspection procedures are to be performed on appliances that are operating where there are no unsafe conditions or corrective repairs have been completed. G.5.1 General Appliance Operation. (1) Initial Startup. Adjust the thermostat or other control device to start the appliance. Verify that the appliance starts up normally and is operating properly. Determine that the pilot(s), where provided, is burning properly and that the main burner ignition is satisfactory, by interrupting and re-establishing the electrical supply to the appliance in any convenient manner. If the appliance is equipped with a continuous pilot(s), test all pilot safety device(s) to determine whether it is operating properly by extinguishing the pilot(s) when the main burner(s) is off and determining, after 3 minutes, that the main burner gas does not flow upon a call for heat. If the appliance is not provided with a pilot(s), test for proper operation of the ignition system in accordance with the appliance manufacturer's lighting and operating instructions. (2) Flame Appearance. Visually inspect the flame appearance for proper color and appearance. Visually determine that the main burner gas is burning properly (i.e., no floating, lifting, or flashback). Adjust the primary air shutter as required. If the appliance is equipped with high and low flame controlling or flame modulation, check for proper main burner operation at low flame. (3) Appliance Shutdown. Adjust the thermostat or other control device to shutdown the appliance. Verify that the appliance shuts off properly. G.5.2 Test for Combustion Air and Vent Drafting for Natural Draft and Category I Appliances. Combustion air and vent draft procedures are for natural draft and category I appliances equipped with a draft hood and connected to a natural draft venting system. (1) Preparing for Inspection. Close all building doors and windows and all doors between the space in which the appliance is located and other spaces of the building that can be closed. Turn on any clothes dryer. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers and any fireplace doors.

145 (2) Placing the Appliance in Operation. Place the appliance being inspected in operation. Adjust the thermostat or control so the appliance will operate continuously. (3) Spillage Test. Verify that all appliances located within the same room are in their standby mode and ready for operation. Follow lighting instructions for each appliance as necessary. Test for spillage at the draft hood relief opening as follows: a. After 5 minutes of main burner operation check for spillage using smoke. b. Immediately after the first check turn on all other fuel gas burning appliances within the same room so they will operate at their full inputs and repeat the spillage test. c. Shut down all appliances to their standby mode and wait for 15 minutes. d. Repeat the spillage test steps a through c on each appliance being inspected. (4) Return doors, windows, exhaust fans, fireplace dampers, and any other fuel gas burning appliance to their previous conditions of use. (5) If, after completing the spillage test it is believed sufficient combustion air is not available, the owner should be notified that an alternative combustion air source is needed in accordance with Section 9.3 of the National Fuel Gas Code. Where it is believed that the venting system does not provide adequate natural draft, the owner should be notified that alternative vent sizing, design or configuration is needed in accordance with Chapter 11 and 12 of the National Fuel Gas Code. G.6 Appliance-Specific Inspections. The following appliance-specific inspections are to be performed as part of a complete inspection. These inspections are performed either with the appliance in the off or standby mode (indicated by OFF ) or on an appliance that is operating (indicated by ON ). The CO measurements are to be undertaken only after the appliance is determined to be properly venting. The CO detector should be capable of calculating CO emissions in ppm air free. (1) Forced Air Furnaces: a. OFF. Verify that an air filter is installed and that it is not excessively blocked with dust. b. OFF. Inspect visible portions of the furnace combustion chamber for cracks, ruptures, holes, and corrosion. A heat exchanger leakage test should be conducted. c. ON. Verify both the limit control and the fan control for proper operation. Limit control operation can be checked by blocking the circulating air inlet or temporarily disconnecting the electrical supply to the blower motor and determining that the limit control acts to shut off the main burner gas. d. ON. Verify that the blower compartment door is properly installed and can be properly resecured if opened. Verify that the blower compartment door safety switch operates properly. e. ON. Check for flame disturbance before and after blower comes on which may indicate heat exchanger leaks. f. ON. Measure the CO in the vent after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6. (2) Boilers: a. OFF and ON. Inspect for evidence of water leaks around boiler and connected piping. b. ON. Verify that the water pumps are in operating condition. Test low water cutoffs, automatic feed controls, pressure and temperature limit controls, and relief valves in accordance with the manufacturer's recommendations to determine that they are in operating condition. c. ON. Measure the CO in the vent after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6. (3) Water Heaters: a. OFF. Verify that the pressure temperature relief valve is in operating condition. Water in the heater should be at operating temperature. b. OFF. Verify that inspection covers, glass, and gaskets are intact and in place on a flammable vapor ignition resistant (FVIR) type water heater. c. ON. Verify that the thermostat is set in accordance with the manufacuturer s manufacturer s operating instrucitons instructions and measure the water temperature at the closest tub or sink that it is no greater than 120ºF. d. OFF. Where required by the local building code in earthquake prone locations, inspect that the water heater is secured to the wall studs in two locations (high and low) using appropriate metal strapping and bolts. e. ON. Measure the CO in the vent after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6. (4) Cooking Appliances a. OFF. Inspect oven cavity and range-top exhaust vent for blockage with aluminum foil or other materials.

146 b. OFF. Inspect cook top is free from a build-up of grease. c. ON. Measure the CO in above each burner and at the oven exhaust vents after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6. (5) Vented Room Heaters a. OFF. For built-in wall heaters and furnaces inspect that the burner compartment is free of lint and debris. b. OFF. Inspect that furnishings and combustible building components are not blocking the heater. a. ON. Measure the CO in the vent after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6. (6) Vent-Free Heaters a. OFF. Verify that the heater input is a maximum of 40,000 Btu input, but not more than 10,000 Btu where installed in a bedroom, and 6,000 Btu where installed in a bathroom. b. OFF. Inspect the ceramic logs provided with gas log type vent free heaters that they are properly located and aligned. c. OFF. Inspect the heater that it is free of excess lint build-up and debris. c. OFF. Verify that the oxygen depletion system has not been altered or bypassed. d. ON. Verify that the main burner shutdowns within 3 minutes by extinguishing the pilot light. The test is meant to simulate the operation of the oxygen depletion system (ODS). e. ON. Measure the CO after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6. (7) Gas Log Sets and Gas Fireplaces a. OFF. For gas logs installed in wood burning fireplaces equipped with a damper verify that the fireplace damper is in a fixed open position. b. ON. Measure the CO in the firebox (logs sets installed in wood burning fireplaces or in the vent (gas fireplace) after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6. (8) Gas Clothes Dryer a. OFF. Where installed in a closet, verify that a source of make-up air is provided and inspect that any make-up air openings, louvers, and ducts are free of blockage. b. OFF. Inspect for excess amounts of lint around the dryer and on dryer components. Inspect that there is a lint trap properly installed and it does not have holes or tears. Vertiy that it is clean condidtion. c. OFF. Inspect visible portions of the moisture exhaust duct and connections for loose fittings and connections, blockage, and signs of corrision. Vertify that the duct termination is not blocked and that it terminates in an outdoor location. Verify that only approved metal vent ducting material is installed (plastic and vinyl materials are not approved for gas dryers). d. ON. Verify mechanical components including drum and blower for proper operation. e. ON. Operate the clothes dryer and vertify that exhuast system is intact and exhaust is exiting the termination. f. ON. Measure the CO in at the exhaust duct or termination after 5 minutes of main burner operation. The CO should not exceed threshold in Table G.6.
