HE Series Infrared Gas Heater Installation and Operation Manual
Clearance to Combustibles
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 the 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 117F° (65C°) 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 tolerance
materials include vinyl siding, fabrics, some plastics, filmy materi-
als, etc.
IMPORTANT:
A peel and stick sign is included with this heater to specify the required clear-
ances from the heater to any combustible materials or vehicle. The sign must be posted
either adjacent to the heater thermostat or in the absence of such thermostat in a
conspicuous location.
In addition to stored or stationary material, consideration must also be
given to moveable objects such as vehicles and overhead doors, and structural objects such as
shelving, sprinkler heads, electrical and gas lines, and electrical fixtures.
Do not store any combustible materials or install shelving or other projections within the
“ Clearance to Combustibles ” box - see Figure 1 and Table 1 on the next pages.
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 1 and Table 1 in this manual, and/or the rating label affixed to the burner
housing for the certified clearances to combustibles for the heater
.
