The American Gas Association (AGA) supports both the 2002 National Fuel Gas Code (NFGC) and the 2003 International Fuel Gas Code (IFGC). Both codes are technically complete, up-to-date, and contain consistent coverage. Both will provide installers and code officials with the necessary provisions to help ensure the safe installation and inspection of gas equipment. AGA has compiled a detailed side by side comparison between the IFGC and the NFGC. This comparison is provided in PDF format.
