What code governs the installation of fuel gas piping in residential buildings?

The governance of fuel gas piping installation in residential buildings is primarily under the National Fuel Gas Code, which is identified as NFPA 54 / ANSI Z223.1. This code provides the essential standards for the safe installation and operation of fuel gas piping systems. It ensures proper design, materials, and procedures to prevent hazards associated with gas leaks, combustion, and other potential risks.

The National Fuel Gas Code outlines critical aspects, including sizing of gas piping systems, pressure regulation, and safety measures that must be adhered to during the installation and maintenance of these systems. This is crucial for ensuring the safety and efficiency of gas appliances and installations within residential settings.

Other codes listed, such as the International Plumbing Code, Uniform Mechanical Code, and Building Energy Code, cover different aspects of building systems but do not specifically address the unique requirements for fuel gas piping. Instead, they focus on plumbing systems, mechanical systems, and energy conservation, respectively. Thus, while they contribute to overall building safety and efficiency, they are not the primary authority governing fuel gas installations.
