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

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.
