What is the minimum height to install a furnace in a repair garage?

The minimum height for installing a furnace in a repair garage is specified to ensure safety and proper clearance for maintenance and operations. It is crucial to maintain a certain distance between the furnace and the floor to prevent potential damage from spills or debris that may occur in a garage environment. By installing the furnace at a height of at least 54 inches, it minimizes the risks associated with flammable materials, allows for improved airflow, and ensures that the unit can be accessed safely for inspections and repairs. This height aligns with safety codes and regulations relevant to gas-fueled appliances in non-residential settings like repair garages, effectively addressing both operational safety and code compliance.
