Design Considerations and Prechecks
Placement of infrared heaters is influenced by many factors. Aside from safety factors, considerations
such as the number of heaters 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, 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 burner control box, tubes, vents, and combustion air intake ducts. Inspect and evaluate the
mounting conditions, vent locations, gas supply, and wiring.
CNG maintenance facilities have special design requirements regarding mounting heights, ventilation,
and other factors. It is important to follow the guidelines in this manual, as well as all local, state, and
federal guidelines. NFPA 30A, NFPA 52, and all other applicable standards should also be consulted.
Contact the factory for more information.
When designing an infrared radiant heating system, consider the following:
• Has the building’s heat loss been evaluated?
• Does the design meet the needs of the space?
• Have recommended mounting heights been observed?
• Have all clearances to combustibles situations been observed?
• Is the supply (burner) end of the heater located where more heat is required?
• Is it best to offset the heaters and/or rotate the reflectors towards the heat zone?
• Are extra guards, side shields, ‘U’ or ‘L’ reflector covers required?
• Does the heater require outside fresh air for combustion?
• Is the environment harsh or contaminated (requiring outside air for combustion)?
•
Are chemicals or vapors a concern (requiring outside air for combustion or additional
ventilation)?
IMPORTANT:
Fire sprinkler heads must be located at an appropriate distance from the heater. This
distance may exceed the published clearances 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.
The effective infrared surface temperature of a person or object may be diminished with wind velocities
above 5 mph. The use of adequate wind barrier(s) may be required.
