Appliance and equipment vent terminals must be located such that doors cannot swing within how many inches horizontally of the vent terminals?

Appliance and equipment vent terminals are critical for proper ventilation and the safe operation of gas appliances. The requirement that these terminals be located a specified distance away from doors is primarily to prevent any interference with the venting process and to avoid hazardous situations.

The correct distance of 12 inches ensures that any potential exhaust or gases being expelled from the vent terminal do not interact with doors swinging open. This positioning minimizes the risk of backdrafts or the possibility of exhaust gases entering building spaces via the doors. This is particularly important in residential and commercial environments to maintain air quality and ensure safety.

By adhering to the 12-inch requirement, the risk of any blockage or unintended airflow patterns created by swinging doors is significantly reduced. The standards set forth in the IMC aim to protect occupants by ensuring safe and efficient ventilation practices.
