3.0 Installation • Design Considerations and Prechecks

3.0 Installation

WARNING

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.

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 wind barriers required? The effective infrared surface temperature of a person or object may be diminished with wind/drafts above 5 mph.

• 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 to avoid an inadvertent discharge. This distance may exceed the published clearance to combustibles. Certain applications may require the use of high temperature sprinkler heads or the relocation of the heaters.

CAUTION

Fire sprinkler systems containing propylene glycol, antifreeze or other potentially ﬂammable substances shall not to 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.

3.0 Installation • Design Considerations

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. The heaters themselves, when installed and serviced in accordance with the installation manual, do not emit foul odors into the environment.

Design Scenario:

A tube heater system is being installed in a 90’ (L) x 50’ (W) x 14’ (H) space. Two overhead doors are located at one end and an equipment storage area on one side. The calculated heat load is 400,000 BTU/h.
