Clearances
Units must be installed so that the clearances listed in Table 5 are provided for with regards to combustion air space,
inspection, and service and for proper spacing from combustible construction. Clearance to combustibles is defined
as the minimum distance from the heater to a surface or object for which it is necessary to ensure that a surface
temperature of 90°F (50°C) above the surrounding ambient temperature is not exceeded. Refer to the dimensions
listed in Table 4 and shown in Figure 2 when determining clearances to combustibles.
