Second Revision No. 3-NFPA 31-2015 [ Section No. 10.5.1 ] 10.5.1* Oil burners, other than oil stoves with integral tanks, shall be provided with some means for manually stopping the flow of oil to the burner. 10.5.1.1 Such device or devices shall be placed in a readily accessible location at a safe distance from the burner. 10.5.1.2 For electrically powered appliances, the requirement of 10.5.1 shall be accomplished by an identified switch in the burner supply circuit, placed outside of and adjacent to the entrance to the room where the appliance is located. 10.5.1.3 For appliances that are not electrically powered, an identifiable valve in the oil supply line, operable from a location that can be reached without passing near the burner, shall be used. Submittal Date: Mon Apr 06 14:06:14 EDT 2015 Second Revision No. 3 implements the text of Input No. 36 as proposed in the First Draft Report, along with the following amendments: (1) In 10.5.1, the reference to oil stoves has been deleted because these units are obsolete and no longer manufactured. (2) In 10.5.1, the reference to "flow of oil" has been deleted because it is the burner, and not just the flow of oil, that needs to be shut. (3) In 10.5.1.1, the reference to safe distance has been deleted because 10.5.1.2 and 10.5.1.3 define the required separation distance.
Second Revision No. 4-NFPA 31-2015 [ Section No. 10.5.2 ] 10.5.2 An electrical service disconnect switch, arranged to stop and start the oil burner, shall be installed at the appliance and shall be located so that it is within easy reach of the service technician for control of the oil burner while observing the flame. 10.5.2.1 A single duplex electrical receptacle shall be permitted to be installed at the same location, wired in parallel with the electrical service disconnect. Submittal Date: Mon Apr 06 14:20:51 EDT 2015 Second Revision No. 4 implements the text of Input No. 36 as proposed in the First Draft Report, along with addition of new 10.5.2.1 which provides for a duplex receptacle for use by the service technician.
Second Revision No. 5-NFPA 31-2015 [ Section No. 10.5.6 ] 10.5.6 A water heater shall be provided with a water pressure, and temperature, and vacuum- relief devices device. Submittal Date: Wed Apr 08 11:47:55 EDT 2015 Second Revision No. 5 implements the text of Input No. 36 as proposed in the First Draft Report. Amendments made to 10.5.6 recognize currently-used combination relief devices. Vacuum relief devices are no longer considered necessary.
Second Revision No. 1-NFPA 31-2015 [ Section No. A.5.2.1.1 ] A.5.2.1.1 One method of testing is as follows: (1) Close fireplace dampers and fireplace door doors, and close all exterior doors and windows in the building, and close all interior doors in the building. (2) Turn on building air exhaust systems, including clothes dryers, range hoods, bathroom exhausts, and mechanical ventilation and forced-air heating or cooling system blowers and operate them at their highest speed setting. Do not operate a whole-house cooling exhaust fan. (3) Operate the burner in the smallest oil heating appliance first, and then other appliances in order of increasing capacity. Measure and record the flue draft and over-fire draft of each appliance, and check for flue gas spillage. (4) Check that the flue draft and over-fire draft are at a level that is required by the oil heating equipment manufacturer as specified in the installation and operating manuals for the appliance. Over-fire draft in oil appliances are usually negative 0.01 to negative 0.02 in. of water column. (5) Return doors, windows, exhaust fans, fireplace dampers, and all fossil fuel burning appliances to their previous conditions of use. The oil heating equipment installer shall take action as needed to correct excessive depressurization of the appliance combustion air zone and return the flue draft of over-fire draft to the requirements of the oil heat equipment manufacturer and/or oil burner manufacturer. Notify the homeowner, building owner, or occupant if combustion air zone depressurization impacts the operation of the oil heating equipment and all actions and modifications that were required allow the flue draft and over-fire draft to the level required by the oil heating equipment manufacturer. The oil heating equipment installer should take action as needed to correct excessive depressurization of the appliance combustion air zone and return the flue draft and over-fire draft to the requirements of the oil heat equipment manufacturer. Submittal Date: Mon Apr 06 13:54:04 EDT 2015 Second Revision No. 1 (which is a Comment to First Revision No. 25) effects the following changes: (1) Replacement of the word "shall" with the word "should", because Annex text is not mandatory. (2) Deletion of redundant text. (3) Correction of transcription errors to improve understanding of the text. In addition, the last paragraph has been deleted, because NFPA 31 is an installation standard. The text of the last paragraph might give the impression that adverse conditions do not need to be
addressed, when, logically, this would be a part of the installation process.
Second Revision No. 2-NFPA 31-2015 [ Section No. A.5.2.3 ] A.5.2.3 Remedial actions to correct excessive negative pressure in the combustion air zone might include the following: (1) Air boots for oil burners to supply outdoor air directly to the burner (2) Air-in-a-can to supply outdoor air into the boiler/furnace room (3) Dedicated make-up air for kitchen exhausts (4) Blocked vent safety shut-offs off devices (5) Make-up air into furnace return ducts with barometric damper (6) Warning labels on whole house fans Submittal Date: Mon Apr 06 14:04:50 EDT 2015 This Second Revision (which is a Comment to First Revision No. 25) is an editorial correction.
