NFPA 54, National Fuel Gas Code Handbook, 2021 Edition
The NFPA 54 Handbook 2021 edition pairs the complete National Fuel Gas Code text with expert commentary that explains the reasoning behind each rule, not just the rule itself. Engineers, contractors, plumbers and inspectors use it to work through the design, installation and operation of fuel gas piping and equipment.
The 2021 handbook includes over 200 full color photos, graphics and calculation worksheets alongside the code text, and it carries several technical updates from the base 2021 code.
This listing is the 2021 edition of the handbook. NFPA now lists a 2027 edition of NFPA 54, so check which year your jurisdiction, contract or exam cites before you order.
