2.0Installation

!WARNING

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 infra-red heater(s). Aside from safety factors such as clearance to combustibles (see Chart 1.1 on page 5), you should take 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 infra-red 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 infra-red 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 futher than the recommended distance (see Figure 2.1 ).

!CAUTION

This heater cannot be used in a building with an uninsulated roof or condensation problems can occur.

Factory recommended mounting heights (see Chart 2.2) are listed as a guideline. If infra-red heaters are mounted too low or too high, they may result in discomfort or lack of heat. The factory generally recommends observing the recommended mounting heights to optimize comfort conditions. However, certain applications such as spot heating, freeze protection, outdoor patio heating or very high ceilings may result in the heaters being mounted outside of the recommended mounting heights.

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.

Potentially flammable substances, such as Propylene Glycol or antifreeze solutions, are not to be used in conjunction with this heater.

For further information consult NFPA 13. Always observe applicable state and local codes.
