FUNCTION AND OPERATING PARAMETERS
This is a forced air heater meaning that a blower or fan pushes the air through the
heater. Proper combustion depends upon the air flow.
Therefore, the heater must not be modified or operated with parts removed or
missing. Likewise, safety systems must not be circumvented or modified in order to
operate the heater.
This heater is intended for drying and the warming of commercial/industrial buildings
where adequate ventilation is provided.
This heater is not intended;
•It must be operated as prescribed in the operating manual.
•It is not intended to be used for domestic use or for the heating of habitable
areas.
•It is not intended to be used to reach and maintain a certain level of human
thermal comfort within an enclosed space in which the heater is situated.
•It is not intended to be used in enclosed areas with restricted ventilation.
•It is not for use in areas with high levels of fluctuating drafts.

SAFETY SYMBOLS
Please read all of the safety and operating instructions carefully before using this
product. The following safety symbols may be found on the product.
Even though this heater operates very close to 100 percent combustion efficiency, it
still produces small amounts of carbon monoxide.
•Carbon Monoxide (CO) is toxic.
•Pregnant women, persons with a heart or lung condition, anemia or under
the influence of alcohol, or those at high altitude, are more likely to be
effected by Carbon Monoxide.
•CO can build up in a confined space and failure to provide adequate
ventilation can be fatal.
The early symptoms of asphyxiation caused by inadequate ventilation are:
•headache•nausea
•dizziness•dry mouth or sore throat
