NOTE:
The clearance to combustible materials noted above must be maintained at all times and the
same clearance distances must be adhered to from any other materials that may be damaged by
temperatures 90
o
F above the ambient temperature. It is the installer’s responsibility to ensure that
building materials with a low heat tolerance (such as plastic, vinyl siding, canvas, tri-ply etc.) which may
degrade at lower temperatures are protected to prevent degradation. Clearances to combustibles are
posted on the reflector near the control end of the heater.
Fire sprinkler heads must be located at an appropriate distance from the heater. This
distance may exceed the published clearance to combustibles. Certain applications will require the use of
high temperature sprinkler heads or relocation of the heaters.
Sprinkler systems containing propylene glycol or other flammable substances are not to be used in
conjunction with this heater without careful consideration for and avoidance of potential fire or explosion
hazards. For further information consult NFPA 13. Always observe applicable state and local codes.

INSTALLER
In locations used for storage of combustible materials where they may be stacked below the heater,
NFPA 54 requires 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. It is important to provide warnings to alert individuals of potential hazards
and safety actions. Posted signs should state the hazards for the particular application and be legible
to building occupants.
