Only the 2002 NFPA 54 helps you work smarter! Utilized by designers, installers, and inspectors nationwide, this invaluable resource serves to improve productivity and reduce accidents. The 2002 edition has been updated to reflect new developments in construction materials, methods, and procedures. In addition, the document also includes an updated and expanded Appliance Input Table that includes more appliances than ever before. Approx. 152 pp.
Major changes and revisions in this edition that need to be recognized and applied to future jobs 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 house
The addition of a new branch length method for pipe sizing that allows for smaller pipe size in branches and can be useful where lengths vary
Recognition of the new flammable vapor ignition-resistant water heaters that can be installed directly on garage floors rather than on an 18-inch elevation
Revised venting provisions that clarify procedures for corrugated liners and vent offsets
Reformatted pipe sizing and venting tables that ensure consistency and ease of use
