Clearances to Combustibles
Placement of explosive objects, flammable objects, liquids, and vapours close to the heater
may result in explosion, fire, property damage, serious injury, or death. Do not store, or use,
explosive objects, liquids, and vapour 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.
The outside surfaces of the heater are hot during operation and after operation. If contact is
made, permanent skin damage may occur. Do not move, handle, or service the unit during
operation or while hot.
Signs shall be posted specifying the maximum permissible stacking height in order to
maintain clearances to combustibles.
Hazards Include:
For maximum safety the building must be evaluated for hazards before installing the heater system.
Examples include, but are not limited to:
• Gas and electrical lines
• Combustible and explosive materials
• Chemical storage areas
• Areas of high chemical fume concentrations
• Provisions for accessibility to the heater
• Adequate clearances around air openings
• Vehicle parking areas
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 indicated surface 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
When installing the infrared heater system, the minimum clearances to combustibles must be maintained.
These distances are shown in Chart 1.1 and on page 6. If you are unsure of the potential hazards, consult
your local fire marshal, fire insurance carrier, or other qualified authorities on the installation of infrared
heaters for approval of the proposed installation.
