The stated clearance to combustibles represents a surface temperature of 90 degree
Fahrenheit (32 degrees Celsius) above room temperature. Building material with a low
heat tolerance may be subject to degradation of lower temperatures. It is the installer’s
responsibility to assure that adjacent material are not subject to degradation.
A warning statement that an overhead heater should be installed so that the minimum
clearances marked on the heater will be maintained from vehicles parked below the
heater.
Minimum clearances (inches) from combustibles measured from radiant surface.
Clearances are reduced by 1/3, 15 ft (4.6 meters) from the burner on EZM models.
For installation at elevations above 2000 ft (610m), the appliance shall be de-rated 4
percent for each 1000 ft (305m) of elevation above sea level.
