MINIMUM CLEARANCES TO COMBUSTIBLES

Minimum clearances to combustibles shall be measured from the outer surfaces as shown in the following
diagram:
Fig. 2

Table 1

ADU25, ADL25
ADU30-45, ADL30-45
▲WARNING: Certain materials or objects, when stored under the heater, will be subjected to radiant heat and
could be seriously damaged. Observe the Minimum Clearances to Combustibles listed in the manual and on the
heater at all times.
NOTE:
1. The clearances specified above must be maintained to combustibles and other materials that may be
damaged by temperatures 32ºC above ambient temperature. Clearances to combustibles are posted on the
control box. In areas used for storage of combustible materials where they may be stacked below the heater, It
is recommended that the installer must post signs that will "specify the maximum permissible stacking height to
maintain the required clearances from the heater to combustibles." Space-Ray recommends posting these signs
adjacent to the heater thermostat or other suitable location that will provide enhanced visibility.
2. The stated clearance to combustibles represents a surface temperature of 32 ºC above room temperature.
Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to
degradation at lower temperatures. It is the installer's responsibility to assure that adjacent materials are
protected from degradation.
