A gas piping installation covered by NFPA 54 includes all fixed piping from where to where?

From the gas meter to the appliance
From the main supply to the utility service
From the outlet of the meter set to the appliance
From the 1st stage regulator to the gas meter

The correct answer is: From the outlet of the meter set to the appliance

The correct choice states that a gas piping installation covered by NFPA 54 includes all fixed piping from the outlet of the meter set to the appliance. This definition aligns with the scope of NFPA 54, which is the National Fuel Gas Code. The reason this option is correct is that NFPA 54 specifically addresses the safety standards for the installation of gas piping systems, which includes requirements for materials, design, and installation procedures. The term "outlet of the meter set" refers to the point where the gas is released for distribution through the fixed piping system, and the code focuses on the piping that transports this gas to a final point, which is the appliance. This coverage ensures that the gas is safely handled up to the appliance that ultimately uses it, thereby reducing risks associated with gas leaks or malfunctions. The emphasis on fixed piping means that any parts of the system intended for transport and not for utility service or internal appliance fittings are considered under this standard. Other potential answers may refer to stages or components of gas supply systems that do not directly fall under the jurisdiction of NFPA 54 regarding fixed piping installations.
