Product Details

The National Fuel Gas Code is the industry standard that designers, installers, and inspectors nationwide rely on to improve productivity and reduce accidents. And this new edition has been updated to reflect the most recent developments in construction materials, methods, and procedures.

Only the 2002 NFPA 54 recognizes today's technologies and construction practices to help you work smarter!

Major changes and revisions that will affect how you do your job include...

• Totally new treatment of the combustion air requirement that eliminates the concept of "unusually tight construction" and provides a definitive calculation method using the actual air exchange of the houseThe addition of a new branch length method for pipe sizing that allows for smaller pipe size in branches and can be useful where lengths varyRecognition of the new flammable vapor ignition-resistant water heaters that can be installed directly on garage floors rather than on an 18-inch elevationRevised venting provisions that clarify procedures for corrugated liners and vent offsetsReformatted pipe sizing and venting tables that ensure consistency and ease of use
• An updated and expanded Appliance Input Table that includes more appliances than ever before
