Building material with a low heat tolerance (such

as plastics, vinyl siding, canvas, tri-ply, etc.)

may be subject to degradation at lower tempera-

tures.

It is the installer’s responsibility to assure that

adjacent materials are protected from

degradation.

1.3 Clearance to Combustibles.

Minimum clearance to combustibles are shown

in Figure 2. Refer to table 1 below.

IMPORTANT:

The stated clearance to combustibles

represents a surface temperature of 90°F

(50° C) above room temperature.

WARNING:

Minimum clearance from the heater must be maintained from vehicles parked below heater.

In all situations, clearances to combustibles must be maintained. Signs should be posted in

storage areas to specify maximum stacking height to maintain required clearance to

combustibles. Such signs must either be posted adjacent to the heater thermostats or in the

absence of such thermostats in a conspicuous location.

Refer to mounting clearance tables.
