Description
Master the complexities of fuel gas safety with the NFPA 54, National Fuel Gas Code Handbook, 2021 Edition. While the standard code provides the “rules,” this essential handbook explains the “how” and “why” behind them. It is the premier resource for engineers, contractors, plumbers, and inspectors who need to ensure the safe design, installation, and operation of fuel gas piping and equipment.
The 2021 Handbook combines the complete code text with expert commentary, providing a narrative interpretation that helps you avoid errors and apply requirements correctly. This edition includes significant technical updates, such as new electrical isolation requirements for underground metallic piping and standardized venting rules for pressure control devices. With over 200 full-color photos, graphics, and calculation worksheets, this handbook transforms complex regulations into clear, actionable guidelines.
Key Updates in the 2021 Edition:
-
Dielectric Fittings: New requirements for installing dielectric fittings at building penetrations to electrically isolate underground metallic piping for corrosion protection.
-
Venting Standardization: Uniform requirements for venting pressure control devices like line pressure regulators and limit controls.
-
Point of Delivery: A new definition in Chapter 3 to clarify where the serving utility’s responsibility ends and the premises wiring begins.
-
Vent Terminal Clearances: Revised through-the-wall clearances to align with ANSI appliance standards and common installation scenarios.
-
Visual Aids: Hundreds of photos, charts, and “At a Glance” tables to streamline piping design and appliance installation.
