Installation

WARNING
Read and understand, the installation, operating and maintenance instructions thoroughly before installing or servicing this equipment.

Design
To ensure a safe, properly designed heating system, a layout should be developed for the correct placement of the infrared heater(s). Aside from safety factors such as clearance to combustibles (see Chart 1.1 on page 6), you should also take into consideration the environment (e.g., cold/drafty, average, protected), heat coverage (sq. ft.) needed, heater centres, the distance behind a person or work station(s). Also, the effective infrared 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 5. When positioning the heaters, keep in mind combustible materials, lights, sprinkler heads, overhead doors, storage areas with stacked materials, gas and electrical lines, parked vehicles, cranes, etc. Refer to Page 6 for minimum clearance to verify that a safe installation exists.  This installation manual, along with national, state, provincial and local codes, addresses these issues. It is critical that you read, understand and follow all guidelines and instructions. Always inspect and evaluate the mounting conditions, application, and wiring. When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehyde, etc.) can evaporate and/or degrade. This may result in odours or fumes being emitted into the environment. To correct this problem, clean the area and/or introduce additional ventilation. Heaters installed and serviced per the installation manual do not emit foul odours into the environment.

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 relocation of the heaters.

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