How high must an appliance be installed in a private garage if it does not meet the code exception?

In a private garage, the installation height of appliances is dictated by safety standards aimed at ensuring that potentially hazardous appliances are not easily damaged or tampered with, especially by vehicles. If an appliance does not meet specific code exceptions, it must be installed at a height of at least 6 feet above the floor. This requirement is primarily designed to prevent accidental contact with the appliance, minimize the risk of fuel spillage, and ensure safety in an environment that may have moving vehicles. The 6-foot height ensures that the appliance is out of reach of potential hazards while accommodating typical vehicle heights in garages. Understanding this specific requirement is crucial for compliance and safety in HVAC installations.
