Installation
Improper installation, adjustment, alteration, service or maintenance can cause
property damage, serious injury or death.
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 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 burner control box, tubes, vents and combustion air intake ducts. Inspect and evaluate the mounting
conditions, vent locations, gas supply and wiring.
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 clearance 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)?
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.
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 the 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 hazards. For
further information, consult NFPA 13.
