WASHINGTON, DC — New and revised provisions regarding the sizing and installation of gas piping, combustion air in tightly constructed homes, and appliance installation are among the features of the 2002 National Fuel Gas Code, which was recently approved by the American National Standards Institute (ANSI).

According to the American Gas Association (AGA), local natural gas utilities and officials of federal, state, and local governments use the National Fuel Gas Code (NFGC) to judge the acceptability of fuel-gas installation. AGA also says that other widely accepted model codes also extract many NFGC provisions, and appliance manufacturers reference it as part of their design-certified installation instructions.

The 2002 National Fuel Gas Code contains major technical revisions that provide new options and requirements on how gas pipe is to be sized and installed, and on how combustion air is to be provided in tightly constructed homes. Other technical changes appear throughout the code in areas such as venting (mechanical drafting systems and corrugated vent connectors).

The recent revisions will also be discussed during a workshop held in Chicago on Nov. 14-15, 2002. The event is co-sponsored by AGA and the National Fire Protection Association (NFPA). For more information on the workshop or to register, visit www.aga.org (website).
