2.0 Installation •Design
Read and understand the installation, operating, 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 1.2 on page 6), consideration
should also be given to factors such as the environment (e.g., cold/drafty, average, protected), heat
coverage (sq. ft.) needed, heater centers, and the distance behind a person or work station(s). Also,
theeective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 5.
When positioning the heaters, keep in mind the location(s) of combustible materials, lights, sprinkler
heads, overhead doors, storage area 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ammable
substances shall not be used in conjunction with this heater without careful consideration for, and
avoidance of, inadvertent discharge hazards. For further information consult NFPA 13. Always
observe applicable state and local codes.
