What is the minimum height above any portion of a building that a single-wall metal pipe vent must terminate within 10 feet horizontally?

• A. 18 inches
• B. 20 inches
• C. 24 inches
• D. 30 inches

Answer: (C)

The correct answer is a minimum height of 24 inches above any portion of a building that a single-wall metal pipe vent must terminate within 10 feet horizontally. This requirement is established to ensure proper venting and to mitigate the risk of gas backdrafting into the building. By maintaining this height, it helps to prevent any exhaust gases from being trapped or re-entering the structure, which could pose safety hazards to the occupants. Additionally, proper termination height protects the vent from being obstructed by structural elements, ensuring efficient operation of the venting system. The requirement for a height of 24 inches aligns with standard safety practices and building codes, which are designed to promote safety in gas venting applications. Proper venting is crucial for the effective operation of appliances and to reduce the risks associated with gas leakage or accumulation.
