A floor furnace has a minimum distance restriction from the nearest wall. What is that distance?

The minimum distance restriction for a floor furnace from the nearest wall is 6 inches. This requirement is established to ensure proper airflow around the furnace, prevent overheating of surrounding structures, and maintain safe operation. Adequate clearance allows enough space for any needed maintenance or service and ensures that the heat from the furnace can circulate effectively throughout the room.

Following the International Mechanical Code, this clearance distance is critical for safety and efficiency, and adhering to it helps to avoid potential fire hazards or malfunctioning of the heater. Keeping the specified distance also assists in maintaining the warranty and compliance with applicable building codes.
