This heater model must be mounted with minimum clearances between the combus-

tion surface and combustibles. The stated clearance to combustibles represents a

surface temperature of 90°F (50°C) above room temperature. Building materials with

a low heat tolerance (such as plastic, 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.
Locate the heater with respect to building construction and equipment so to provide

sufficient clearance and accessibility for servicing and cleaning.

WARNING

Single or multi-heater placement must be such that continuous

operation of the heater or heaters will not cause combustible

materials or materials in storage to attain a temperature in excess

of 150°F (66°C). See Hazard Levels, page 2.

WARNING

Under no circumstances should this heater be installed in

a combustible atmosphere or in a location where the heater

controls can be subjected to ambient temperatures in excess of

150°F (66°C). See Hazard Levels, page 2.

It is recommended that more distance than the minimum clearance be maintained

above the unit whether or not the construction is combustible. This will reduce and/or

eliminate hot spots and possible staining of painted ceiling surfaces. If the unit must

be close to the roof or ceiling, interpose a non-combustible baffle (twice the size of the

reflector) between the unit and the roof or ceiling. Allow at least 2" (52mm) between the

roof or ceiling and the non-combustible baffle. Allow at least 12" (305mm) between the

non-combustible baffle and the top of the heater.
To assure clearances to combustibles are maintained, signs

must be posted specify-

ing the maximum stacking height of material under and near the heater.
