STACKING HEIGHT
•
In locations used for the storage of combustible materials, signs shall be posted to specify the maximum permissible
stacking height to maintain required clearances from the heater to combustibles. (ANSI Z233.1/NFPA 54)
•
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room temperature.
Building materials with low heat tolerance (such as plastic, vinyl siding, canvas, tri-ply, etc.) may be subject to
degradation at lower temperatures. It is the responsibility of the installer to assure that adjacent materials are
protected from degradation (ANSI Z83.19).
•
It is recommended more distance than the minimum clearance be maintained above the unit whether or not the
construction is combustible to 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” (5cm) between the roof or ceiling and the non-combustible
baffle. Allow at least 12” (31cm) between the non-combustible baffle and the top of the heater.

Unit Weight and Allowable Mounting Angle
Before installing the unit, check the supporting structure to determine that it has suf-
ficient load-carrying capacity to support the
weight.
Mounting angle must be within the tolerance allowed.
