INSTALLER

AVOID EQUIPMENT FAILURE

THIS 10 FT. TUBE IS THE

COMBUSTION CHAMBER.

The combustion chamber utilizes either 409 stainless, titanium alloy or aluminized steel -

depending on the model number of your heater.

THIS TUBE MUST BE THE FIRST TUBE

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 model tube heater and conﬁguration must be maintained. Refer to Chart 1.1 below to determine the required distances for your model.

The stated clearance to combustibles represents a surface temperature of 90°F (32°C) 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.
