Description
NFPA 31: Standard for the Installation of Oil-Burning Equipment, 2020 Edition
Heating equipment that burns liquid fuel has to go in to a written standard, and NFPA 31 is that standard. The NFPA 31 2020 edition covers the design, construction and installation of boilers, space heaters and air heating appliances fired by oil. It is published by the National Fire Protection Association as a trade paperback.
Authorities Having Jurisdiction and commercial insurance underwriters work from these rules when they assess a building, whether that is an industrial plant, an office block or multi-family housing. Installers who want a job signed off on the first visit read the same pages.
Which fuels it applies to
The scope runs from light fuels such as kerosene and diesel through standard No. 2 heating oil to the heavier No. 4 grades. Safe handling boundaries differ by grade, and the standard states them for each.
Where the appliance is allowed to sit
Placement takes up a large part of the text. Floor furnaces, boilers, duct heaters, attic systems and central heating appliances each carry their own structural installation constraints, and the clearances are not interchangeable between them.
Venting, exhaust and used oil
- Chimney connectors, vent caps and type L exhaust venting materials.
- Rules for used oil heating units, covering legal reuse, venting and storage.
