2.0 Installation • Design
Read and understand, the installation, operating and maintenance instructions thoroughly
before installing or servicing this equipment.
Only trained, qualified gas installation and service personnel may install or service 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 clearance to combustibles (see
Chart 1.1 on page 5), you should take also into consideration the environment (e.g., cold/drafty, average,
protected), heat coverage (sq. ft.) needed, heater centers, the distance behind a person or work station(s)
and exhaust path. 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, clearance to
combustibles
must always be maintained! Refer to hazards on page 4.
This installation manual, along with national, state, provincial and local codes, address these issues. It is
critical that you read, understand and follow all guidelines and instructions. Always inspect and evaluate
the mounting conditions, space for exhaust, gas supply and wiring.
Perimeter mounting of infrared heaters provides the most effective distribution of heat. The recommended
spacing between the heaters is shown in Chart 2.1. Add additional heaters in the center of the space
when heaters are spaced farther than the recommended distance (see Figure 2.1 ).
When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes, etc.)
can evaporate. 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. This
distance may exceed the published clearance to combustibles. Certain applications will require the use
of high temperature sprinkler heads or relocation of the heaters.
Sprinkler systems containing propylene glycol or other flammable substances are not to be used in
conjunction with this heater without careful consideration for and avoidance of potential fire or explosion
hazards. For further information consult NFPA 13. Always observe applicable state and local codes.
This heater cannot be used in a building with an uninsulated roof or condensation problems can occur.
