Combustible Items Include:
 Wood
 Paper
 Fabric
 Chemicals
 Wall or roof insulation
Moving Objects Include:
 Overhead doors
 Vehicles on lifts
 Cranes
 Hoists
 Car wash equipment
When installing the infra-red heater system, the minimum clearances to combustibles must be maintained.
These distances are shown in Chart below and on the heater. If you are unsure of the potential hazards,
consult your local fire marshal, fire insurance carrier or other qualified authorities on the installation of gas
fired infra-red heaters for approval of the proposed installation. Install the warnings card supplied with each
heater and complete the blank spaces using the clearances from combustibles table below. See Section 21
for a printed copy of the warnings card.
Minimum clearances shall be measured from the outer surfaces as shown below:

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.
