Installation
Read and understand the installation, operation, and maintenance instructions thoroughly
before installing or servicing this equipment .
Design
To ensure a safe, properly designed heating system, a layout should be developed for the correct placement
of the infrared heater(s) .
Aside from safety factors such as clearances to combustibles (see Chart 1 .5 on page 8), consideration should
also be given to factors such as the environment (e .g ., cold/drafty, average, protected), heat coverage (sq . ft .)
needed, heater centers, the distance behind a person or work station(s), etc . Also, the effective infrared
surface temperature of a person or object may be diminished with wind above 5 mph . Wind barrier(s) may be
required . Most importantly, clearances to combustibles must always be maintained! Refer to hazards on page
7 .
When positioning the heaters, keep in mind the location of combustible materials, lights, sprinkler heads,
overhead doors, storage areas with stacked materials, gas and electrical lines, parked vehicles, cranes, etc .
Refer to page 6 for minimum clearances to verify that a safe installation exists .
This installation manual, along with national, state, provincial, and local codes, addresses these issues . It is
critical that you read, understand, and follow all guidelines and instructions . Always inspect and evaluate the
mounting conditions, application, and wiring .
When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes, etc .)
can evaporate and/or degrade . This may result in odors or fumes being emitted into the environment . To
correct this problem, clean the area and/or introduce additional ventilation . Heaters installed and serviced in
accordance with the installation manual do not emit foul odors into the environment .
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater to avoid an
inadvertent discharge . This distance may exceed the published clearances to combustibles . Certain
applications may require the use of high temperature sprinkler heads or relocation of the heaters .
Fire sprinkler systems containing propylene glycol, antifreeze, or other potentially flammable substances
shall not be used in conjunction with this heater without careful consideration for, and avoidance of,
inadvertent discharge hazards . For further information consult applicable NFPA codes . Always observe
applicable state and local codes .
