How high must burners on equipment installed in garages be above the floor?

Burners on equipment installed in garages must be elevated at least 18 inches above the floor to ensure safety. This height requirement is critical for preventing the ignition of flammable vapors that may accumulate near the ground, such as those emitted from gasoline or other substances commonly found in garage environments.

When burners are positioned at this height, there is a significantly reduced risk that flames or heat from the burner could ignite these vapors, thereby minimizing the chances of fire hazards. This standard is generally based on safety regulations and codes designed to protect individuals and property, emphasizing the importance of considering hazardous environments when installing gas-burning appliances.
