CLEARANCE TO COMBUSTIBLES FOR SPACE HEATING AND BROODER INSTALLATION

WARNING: I
n all situations, clearances to combustibles must be maintained. Minimum clearance
from heater must be maintained from vehicles parked below heater. The posting of signs may be
required in storage areas referring to clearances to combustibles to the heater and/or limiting the
stacking height of stored Items near the heater specifying a maximum height. Clearances are not for use
in four (4) sided enclosures. Certain materials or items, when stored under the heater, will be subjected
to radiant heat and could be seriously damaged.
WARNING
: The stated clearance to combustibles represents a surface temperature of 90°F (32°C)
above room temperature. Building material with 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. When in doubt, check heat tolerance of
building material(s) with their manufacturer.
