Clearances
⚠ DANGER ⚠
• 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).
• 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).
⚠ CAUTION ⚠
• 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 ensure
that adjacent materials are protected from degradation (ANSI Z83.19).
• 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.
•
Locate the heater with respect to building construction and equipment so to provide sufficient clearance and
accessibility for servicing and cleaning .
•
This heater model must be mounted with minimum clearances between the combustion surface and combustibles .
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room temperature .
•
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 inches (52 mm) between the roof or ceiling and the non-
combustible baffle . Allow at least 12 inches (305 mm) between the non-combustible baffle and the top of the heater .
•
In locations used for the storage of combustible materials, ensure that signs are posted to specify the maximum
permissible stacking height to maintain required clearances from the heater to combustibles (ANSI Z233 .1/NFPA 54) .
