Operating Precautions
This is a kerosene, direct-red, forced air heater. It’s intended use is primarily
temporary heating of buildings under construction, alteration or repair.
Direct-Fired means that all of the combustion products enter the heated space.
Even though this heater operates very close to 100 percent combustion
efciency, it still produces small amounts of carbon monoxide. Carbon
monoxide (called CO) is toxic. CO can build up in a heated space and failure to
provide adequate ventilation could result in death. The symptoms of inadequate
ventilation are:
• headache
• dizziness
• burning eyes and nose
• nausea
• dry mouth or sore throat
Be sure to follow advice about ventilation in the Safety Precautions section.
Forced Air means that a blower or fan pushes the air through the heater. Proper
combustion depends upon this air ow; therefore, the heater must not be
revised, modied or operated with parts removed or missing. Likewise, safety
systems must not be circumvented or modied in order to operate the heater.
When the heater is to be operated in the presence of other people the user is
responsible for properly acquainting those present with the safety precautions
and instructions, and of the hazards involved.
