What is the minimum distance in inches that a vented wall furnace should be kept from a door swing?

The minimum distance that a vented wall furnace should be kept from a door swing is 12 inches. This requirement is based on safety regulations intended to ensure that the furnace does not interfere with the operation of the door or pose a hazard to occupants. By maintaining this distance, it prevents the risk of accidental contact between the door and the furnace, which could lead to damage to either or create a safety issue, such as blocking the escape route in case of an emergency.

The guideline of 12 inches helps ensure proper airflow around the furnace and allows for adequate access for maintenance and servicing. Additionally, this spacing is also meant to comply with certain building codes, which are designed to protect not just the immediate area around heating appliances but also the overall safety of the living environment.
