4.0) MINIMUM CLEARANCES TO COMBUSTIBLES
Minimum clearances to combustibles shall be measured from the outer surfaces as shown in the following
diagram:

MINIMUM CLEARANCES TO COMBUSTIBLES
Side Above Below End Front Rear
LRDL15/25 510mm 450mm 1220mm 510mm 610mm 305mm
LRDL30/35/40/45 760mm 610mm 2285mm 610mm 760mm 380mm
▲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 50ºC 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,
NFPA54 requires that the installer must post signs that will “specify the maximum per missible 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 50 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 instal
ler’s responsibility to assure that adjacent materials are
protected from degradation.
