WHEN INSTALLED INDOORS FOR COMFORT OR SPACE HEAT
Also refer to "Outdoor" definition and requirements on page 16

And refer to Indoor Ventilation Requirements Section 14

WARNING
Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire
or explosion and result in property damage, injury or death. Do not use, store or locate flamma-
ble or explosive objects, liquids or vapors in proximity of the heater.
The clearance to combustible material represents the minimum dis-
tance that must be maintained between the outer heater surface and
a nearby surface. The stated clearance to combustibles represents a
surface temperature of 90F° [50C°] above room temperature.
It is the installer's responsibility to ensure that building materials
with a low heat tolerance which may degrade at lower temperatures
are protected to prevent degradation. Examples of low heat toler-
ance materials include vinyl siding, fabrics, some plastics, filmy ma-
terials, etc.
In locations used for the storage of combustible materials, signs must be posted to specify the
maximum permissible stacking height to maintain the required clearances from the heater to
the combustibles. Such signs must either be posted adjacent to the heater thermostats or in
the absence of such thermostats in a conspicuous location.
In addition to stored or stationary material, consideration must also be given to moveable ob-
jects such as cranes, vehicles, and overhead doors, and structural objects such as electrical
and gas lines, electrical fixtures, and sprinkler heads.
Heaters must be located an appropriate distance from sprinkler heads. This distance may be
greater than the certified clearance to combustibles. Check the temperature rating of the sprin-
kler heads and locate heaters at a safe distance - in some instances the sprinkler heads may
need to be replaced by higher temperature heads.
It is beyond the scope of these instructions to consider all conditions that may be encountered.
Consult local authorities such as the Fire Marshall, insurance carrier, or safety authorities if you
are uncertain as to the safety or applicability of the proposed installation.
Refer to Figure 3 and Table 3 NEXT PAGE for the mounting requirements and certified
clearances to combustibles for indoor installation. Also refer to ventilation requirements for
indoor installations on page 19.
WARNING
of combustion to escape from the heater to atmosphere when installed outdoors, or to me-
chanical exhaust withdrawal when installed indoors. Also refer to "Outdoor" and "Indoor" defi-
nitions and requirements on page 11.
Do not allow the products of combustion to accumulate in any space or enclosure.
Clearance to Combustibles
DO NOT INSTALL THIS APPLIANCE IN A RECESS, ALCOVE,
OR ENCLOSURE.
Adequate free space must be provided to allow the products
