A critical safety factor to consider before installation is the clearances to combustibles. 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:
Moving Objects:
• Wood
• Chemicals
• Overhead doors
• Hoists
• Paper
• Wall or roof insulation
• Vehicle lifts
• Car wash equipment
• Fabric
• Cranes
Hazards:
For maximum safety the building must be evaluated for hazards before installing the heater system. 
Examples include, but are not limited to:
Children and adults should be alerted to the hazards for high surface temperatures and should stay away 
to avoid burns or clothing ignition.
Young children should be carefully supervised when they are in the same space as the heater. 
Clothing or other flammable materials should not be hung from the heater, or placed on or near the heater. 
Any guard or other protective device removed for servicing the heater must be replaced prior to operating 
the heater. 
Installation and repair should be done by a qualified service person. The heater should be inspected 
before use and at least annually by a qualified service person. More frequent cleaning may be required as 
necessary. It is imperative that the control compartment, air passage ways and burner of the heater are 
kept clean.

Placement of explosive objects, flammable objects, liquids and vapors close 
to the heater may result in explosion, fire, property damage, serious injury or 
death. Do not store, or use, explosive objects, liquids and vapor in the vicinity 
of the heater.
Failure to comply with the published clearances to combustibles could result in personal injury, death and/
or property damage.
In locations used for the storage of combustible materials, signs must be posted to specify 
the maximum permissible stacking height to maintain the required clearances from the 
heater to the combustibles. Signs must either be posted adjacent to the heater thermostats 
or in the absence of such thermostats, in a conspicuous location.
