The minimum termination height for a single-wall metal pipe vent above the highest point it passes through a roof is established by building codes and safety regulations to ensure proper ventilation and to prevent the escape of harmful gases into living spaces. A termination height of 2 feet is required to ensure that any fumes and gases are expelled safely away from the building structure. This height also helps to maintain clear airflow and reduces the chances of backdraft, where exhaust gases could potentially enter the building instead of being expelled.

The regulations are designed with safety in mind, taking into account factors such as nearby structures, roof pitches, and wind effects that can influence the dispersal of exhaust gases. A minimum of 2 feet ensures adequate clearance, providing a safe distance for the venting of combustion gases and contributing to effective venting performance.
