Form #43219000
May 2021
A critical safety factor to consider before installation is the clearances to combustible materials. Clearance to
combustibles is defined as the minimum distance you must have between the infrared surface, or reflector,
and the combustible item. Considerations must also be made for moving objects around the infrared heater.
The following is a partial list of items to maintain clearances from:
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 19
for a printed copy of the warnings card.
Minimum clearances shall be measured from the outer surfaces as shown below:
