3.0 Installation • Design Considerations and Prechecks

Design Considerations and Prechecks

Placement of infrared heaters is inﬂuenced by many factors. Aside from safety factors, considerations

such as the number of heater or vent elbows that are allowed, maximum vent lengths, ducting of

combustion air and combining exhaust vents are a few examples. All installation manuals, along with

national, state, provincial and local codes, address these issues. It is critical that you read, understand

and follow all guidelines and instructions.

To ensure a properly designed heating system, a layout should be developed for the correct placement of

the heating appliance, vents and combustion air intake ducts. Inspect and evaluate the mounting

conditions, vent locations, gas supply and wiring. Refer to Chart 3.1 on page 11 for the recommended

mounting heights and coverages for the model being installed.

The effective infrared surface temperature of a person or object may be diminished with wind above 5

mph. The use of adequate wind barrier(s) may be required.

NOTE: 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 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 as posted on the heater. Certain

applications may 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.
