WARNING
!
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 or vapor in the vicinity of the heater.
Clearance to combustibles is defined as the minimum distance that must exist between the tube surface,
or reflector, and any combustible items (see Figure 1.1). It also pertains to the distance that must be
maintained from moving objects around the tube heater. When installing the tube heater system, clearances
to combustibles for the Series tube heater and configuration must be maintained.

•
Clearance to Combustibles
The stated clearance to combustibles represents a surface temperature of 90ºF (32ºC) above room
temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas,
tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to
assure that adjacent materials are protected from degradation.
*
Heaters mounted on an angle between 0° to 45° must maintain clearances posted for 0° or 45°; whichever is greater.
