NFPA 31: Standard for the Installation of Oil-Burning Equipment
NFPA 31: 燃油设备安装标准
1.1 Scope.
1.1.1 This standard shall apply to the installation of stationary oil-burning equipment and appliances, including but not limited to industrial-, commercial-, and residential-type steam, hot water, or warm air heating plants; domestic-type range burners and space heaters; and portable oil-burning equipment.
1.1.2 This standard shall also apply to all accessory equipment and control systems, whether electric, thermostatic, or mechanical, and all electrical wiring connected to oil-fired equipment.
1.1.3 This standard shall also apply to the installation of oil storage and supply systems connected to oil-fired equipment and appliances.
1.1.4 This standard shall also apply to those multi-fueled appliances in which fuel oil is one of the optional fuels.
1.1.5* This standard shall not apply to internal combustion engines, oil lamps, or portable devices not specifically covered in this standard. (See Chapter 11 for portable devices that are covered in this standard.)
The 2011 NFPA 31 now covers all liquid fuels -- not just petroleum-based oils -- that are approved for use in oil-burning appliances, such as boilers, air heaters, and water heaters.
Updated to reflect industry developments, the 2011 NFPA 31: Standard for the Installation of Oil-Burning Equipment is the new industry benchmark for correct installation of liquid fuel-burning appliances in industrial, commercial, and residential occupancies.
Substantive changes and improvements in the 2011 edition include:
· Expanded section on acceptable fuels for liquid fuel-burning appliances now includes biodiesel blends, biofuels, and recycled lubrication oil, in addition to No. 2 fuel oil.
· Specifications for minimum thickness for different diameters of steel pipe vent connectors
· Major revisions to Chapter 7, Liquid Fuel Tanks, to consolidate requirements for fill and vent openings; conform to leak testing and inspection requirements of NFPA 30; and address removal of fuel oil tanks from service, with a provision to allow keeping the tank on site to allow for future use
· Major technical and editorial revisions to Chapter 8: Heating Fuel Piping Systems, including consolidation of vent piping requirements into one section; consolidation of piping requirements for cross-connected tanks; consolidation of requirements for special piping arrangements; and specific requirements for proper use of audible tank fill alarms (tank vent whistles)
This widely-used Standard important working tool for anyone involved with the design or installation of liquid fuel-burning appliances and their fuel supply. (Softbound, 58 pp., 2011)
