Safety Labels and Locations • Clearance to Combustibles
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 your series tube heater and
configuration must be maintained. Refer to Chart 1.1 on the following page to determine the required
distances for your model.
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.
