How high must a single-wall metal pipe terminate above a structure within 10 feet horizontally?

• A. 12 inches
• B. 20 inches
• C. 24 inches
• D. 30 inches

Answer: (C)

The requirement for a single-wall metal pipe terminating above a structure within a specific horizontal distance is grounded in safety regulations aimed at preventing the accumulation of harmful gases and ensuring adequate venting. A termination height of 24 inches above the structure is specified to create sufficient clearance that allows for effective dispersion of gases and smoke away from the building. This height helps mitigate the risk of hazardous fumes entering the structure or affecting neighboring areas, maintaining a safe environment for occupants. When a pipe is too low, it may not effectively divert exhaust gases upward and away, especially in varying weather conditions, such as strong winds that could push gases downwards. Therefore, having a minimum height of 24 inches ensures compliance with safety standards, providing an added layer of protection for both the structure and its occupants.
