Where gas piping is installed in conduit that terminates outdoors, how many inches must the conduit extend outside the building?

• A. 2 inches
• B. 3 inches
• C. 4 inches
• D. 5 inches

Answer: (C)

The correct answer, which states that the conduit must extend outside the building by 4 inches, is based on the safety and building code regulations that govern gas piping installations. This requirement is designed to ensure that any moisture or condensation that may accumulate in the conduit cannot enter the building and affect the integrity of the gas piping system. The 4-inch minimum extension is sufficient to create a reliable barrier against the elements, helping to prevent potential leaks or corrosion that could occur if the conduit were to terminate flush with the building exterior. Such specifications are critical in maintaining the safety and efficiency of gas systems, as they help to safeguard against hazards caused by gas leaks or the infiltration of water into the piping system. Ensuring adherence to this guideline is particularly important in regions that experience varying weather conditions, which can affect the durability and safety of the gas piping infrastructure.
