What is the minimum clearance requirement for gas wall furnaces from door swings?

The minimum clearance requirement for gas wall furnaces from door swings is 12 inches. This regulation ensures adequate space for both safety and functionality. Having a 12-inch clearance helps prevent any interference with the operation of the furnace, allows for easy access for maintenance, and minimizes the risks of a door impacting the furnace or its exhaust. Adequate clearance is vital to facilitate proper air circulation and maintain the efficiency of the furnace, as well as ensuring that heat exchange is unobstructed. This regulation reflects standard safety practices in building codes, which are designed to protect both the equipment and the occupants of a building.
