12 12 of /3/ :03 PM Public Input No. 32-NFPA 13D-2016 [ New Section after ] TITLE OF NEW CONTENT Press-Connect Fitting- A permanent mechanical connection for joining copper tubing, steel and stainless steel pipe utilizing elastomeric seal or an elastomeric seal and corrosion-resistant grip ring or rings. Fitting connections are made with a pressing tool and jaws or rings approved by the fitting manufacturer for use in accordance with the product listing. Currently there is no definition for Press-Connect fittings in NFPA 13D. The term Press-Connect Fitting is used in both the IAPMO and ICC codes. The wide use of Mechanical type fittings has created the need to identify fittings such as Press-Connect and provide definitions to prevent confusion between mechanical fitting types and to help identify the correct standards these fittings are required to be listed to. This definition is proposed to prevent confusion within the industry and aligns definitions for these type fittings. This definition will also help to prevent incorrect terminology in the industry such as referring to Press-Connect fittings as Propress which we have all commonly seen. As the Manufacturer of Propress we do like that our brand name is the name used by those in the industry when referring to Press-Connect fittings, but we do want the industry to have the correct terminology of the fittings to avoid any confusion between manufactured products.

Refernce to Press-Connect within the code. Submitter Full Name: Mark Fasel Organization: Viega Llc Submittal Date: Thu Jun 02 11:57:06 EDT 2016 Resolution: Connection methods are either included in tables listing pipe and fittings that do not require specific listings, or are covered by a manufacturers specific listings. No other connection methods are defined in the standard and the task group doesn t believe there is a need to add this definition either.

13 13 of /3/ :03 PM Public Input No. 45-NFPA 13D-2016 [ New Section after ] Sprinklers having a temperature rating of 250 F to 300 F (121 C to 149 C) shall be classified as high temperature-rated sprinklers. High temperature-rated sprinklers are called out in (4) and as such should be defined in the same manner as ordinary and intermediate temperature-rated sprinklers are. Submitter Full Name: Melisa Rodriguez Organization: Uponor Submittal Date: Thu Jun 23 09:20:50 EDT 2016 Resolution: FR-3-NFPA 13D-2016 Agree with submitter. First draft revision created.

14 14 of /3/ :03 PM Public Input No. 77-NFPA 13D-2016 [ Section No. 4.4 ] 4.4 Smoke Alarms. Smoke When provided, smoke alarms shall be provided installed in accordance with NFPA D does not govern the requirements for the installation of smoke alarms. A local alarm is a foundational and critical element to the 13D standard, and this provision is retained adequately in section 7.6, which requires a waterflow alarm in systems installed in homes without smoke alarms installed in accordance with NFPA 72. Submitter Full Name: Chase Browning Organization: Medford Fire Rescue, Medford Oregon Submittal Date: Tue Jun 28 23:41:44 EDT 2016 Resolution: It was decided to delete this requirement in it's entirety.

15 15 of /3/ :03 PM Public Input No. 56-NFPA 13D-2016 [ Section No ] Tanks, expansion tanks, gauges, pumps, hangers, waterflow detection devices, and valves shall not be required to be listed. Based on independent testing, some unlisted hangers used on NFPA 13D sprinkler systems have caused the sprinkler system to catastrophically fail during a fire scenario. A specific example of an unlisted hanger that has been witnessed to fail is the talon clamp with nail. This hanger clamp has a lower melting point than the required sprinkler head activation temperature and actually caused an entire section of the system piping to collapse, rendering the sprinkler system ineffective. If listed hangers are required, this potential hazard can be avoided with little impact to the overall system cost, in keeping with the intent of the standard to provide affordable protection from fire for residents of one- and two-family dwellings. Submitter Full Name: Tony Fleming Organization: Metropolitan Fire Protection Submittal Date: Mon Jun 27 20:57:35 EDT 2016 Resolution: FR-47-NFPA 13D-2016 Two new components were added to this section, and the multiple items put into list form, starting with the water source. The water supply pipe and fittings only need to meet the standards of the local plumbing code in accordance with 5.3. Connections between a tank and pump are typically a non-listed hose or flexible connection. The 5' limitation was included to prevent having a long distance between the tank and pump. Statement: Based on independent testing, some unlisted hangers used on NFPA 13D sprinkler systems have caused the sprinkler system to catastrophically fail during a fire scenario. A specific example of an unlisted hanger that has been witnessed to fail is the talon clamp with nail.

When making connections to copper tube in these types of systems using fittings that are not specifically listed they must be brazed. Section allows the use of specifically listed products so Copper Press Connect fittings (and any other type of fittings/connections) are permitted to be used as long as they are specifically listed for that use.

26 26 of /3/ :03 PM Public Input No. 23-NFPA 13D-2016 [ Section No ] Joints for the connection of copper tube for wet pipe systems and antifreeze systems shall be solder joints, press-connect or be brazed. Currently only soldered or brazed joints are allowed for joining copper per this section The addition of press-connect will eliminate the confusion for allowable copper pipe joining as press-connect fittings are the most widely used joints outside of brazed or soldered joints. Section allows other types of fittings to be used where listed for sprinkler systems but there is a need to identify press-connect fittings within the body of the code as their use is now very familiar with building officials, designers and installers and it will help to clarify terminology when referring to these fittings as Press-Connect and not Propress or Sharkbite names which are commonly used to describe Press-Connect and Push Fit style fittings. By adding this terminology it will eliminate confusion of the name of the fitting type.

35 35 of /3/ :03 PM Public Input No. 90-NFPA 13D-2016 [ New Section after ] TITLE OF NEW CONTENT Type your content here... (5) Sprinklers in closets containing ventless clothes dryers shall be of the intermediate-temperature classification or higher. Ventless clothes dryers placed within closets have the potential to raise ceiling temperatures above 100 F (38 C) for sustained periods of time, potentially weakening the operating mechanisms of ordinary temperature rated fire sprinklers over months or years of use, leading to inadvertent operations. While ventless clothes dryers have been used in Europe for many years, they are fairly new to the North American market, where vented clothes dryers have been the norm. More expensive than vented dryers, they generally incorporate condensers in a two-loop system to first heat some incoming air, allowing it to absorb moisture from the damp clothes, then continually condense the heated moist air to release the water before recirculating the resulting dry air within the clothes dryer. Unlike vented dryers, where moist heated air is exhausted to the building exterior, these devices capture the water to a drain or pan, while the heat from the condensing cycle is exhausted into the immediate area. The condensers in combination machines that both wash and dry the clothes are generally water-cooled, such that quantities of cold water are used to condense the moisture evaporated from the clothes during the drying cycle, and pumped away through the drain line. But the standalone dryer units are air-cooled, using the ambient air as a heat sink. While this heat can be dissipated in a large laundry room, it can be expected to raise the temperatures within a laundry closet to levels unacceptable for ordinary temperature rated sprinklers. All standalone ventless dryers in the market are reportedly of this type.

(FIGURE 2) Reasoning: The point of the allowance is to find a distance far enough away from an obstruction to clear the bottom of the obstruction and provide fire protection below it. On flat ceilings the B distance is static. In sloped applications the B distance changes each time you arrive at a new A distance. The equation does not work unless you already have the sprinkler in position. In Figure 2, the B distance is static and the designer or installer can arrive at a distance without first needing to know where the sprinkler is.
