Model Gas Installation Codes and Standards

Fact Sheet

Model Gas Installation Codes and Standards


Most states, municipalities and government agencies adopt one of three available model gas installation codes to help judge the acceptability of gas installations, including gas piping, combustion air, venting systems and appliance location and installation. These model gas codes are developed by national consensus code-writing organizations. The three model codes currently available for adoption include:


Model Fuel Gas Code Consensus Code Development Organization

International Fuel Gas Code

International Code Council, American Gas Association

National Fuel Gas Code

American Gas Association, National Fire Protection Association

Uniform Mechanical/
Plumbing Code

International Association of Plumbing & Mechanical Officials, National Fire Protection Association

In addition, nationally recognized standards for energy conservation, indoor ventilation and appliances are developed by consensus standard-writing organizations. These standards can affect gas installations and are used by the building design community or adopted by governmental entities. Three of the influential standard-writing organizations and their standards include the following:

Standard Consensus Standard Development Organization

ASHRAE 90.1, Commercial Building Energy Conservation
ASHRAE 62.1, Building Ventilation

The American Society of Heating, Refrigeration and Air Conditioning Engineers

International Energy Conservation Code

International Code Council

ANSI Z21/83, Appliance Standards

CSA International

AGA Viewpoint

Technically sound and nationally consistent model codes and standards help ensure that gas installations are a safe and viable option for consumers. AGA s Building Energy Codes and Standards (BECS) Committee continuously monitors the model building codes and standards, submitting proposals and challenges to the various code and standard developing groups. These efforts ensure that the codes and standards remain technically sound and consistent across the nation.
