The 2009 International Fuel Gas Code addresses the design and installation of fuel gas systems and gas-fired appliances through requirements that emphasize performance. It is fully compatible with the requirements of other codes in the International Codes Series.
Topics covered include gas piping installations, chimneys and vents, gaseous hydrogen systems, and specific appliances, such as forced-air warm-air furnaces, vented gas fireplaces, vented wall furnaces, floor furnaces, duct furnaces, clothes dryers, sauna heaters, pool and spa heaters, air-conditioning equipment, refrigerators, water heaters, illuminating appliances, engine and gas turbine-powered equipment, cooking appliances, both vented and unvented room heaters, and more.
New to the 2009 International Fuel Gas Code:
- In new Section 310.1.1, bonding requirements were added that specifically pertain to CSST piping systems. The bonding requirements are intended to reduce the chance of damage to the piping from lightning induced electrical energy.
- Section 505.11 was revised in an attempt to eliminate the problem
created by appliance/hood interlock arrangements that shut off the
gas supply to appliances equipped with standing pilot ignition systems.
- To prevent the entry of combustion products into a building, new
Section 503.16 requires all vents that penetrate an exterior wall to be permanently sealed around the penetration.
- New Section 411.3 addresses the special installations involving
infrared radiant tube heaters and so called "flexible" gas appliance connectors. The heater installation instructions require a specific connector configuration.
- The maximum length of clothes dryer exhaust ducts has increased to 35 feet and the deduction for the equivalent length of fittings is tied to the type of fitting design and turning radius.
- New Section 630.3 requires special ventilation in any space in which unvented infrared heaters are installed.
- Section 304.4 was reworded to make it quite clear that makeup air must be provided to any space in which exhaust fans, kitchen hoods and/or clothes dryers are capable of depressurizing the space and interfering with the function of appliance vents and chimneys.
- The revisions to Section 407.2 make it clear that all materials and devices used to hang or otherwise support gas piping must be constructed of metal.
