OPERATING PRECAUTIONS
This is a oil/kerosene, direct-fired, forced air heater. Its 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 efficiency, 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 flow. Therefore, the heater
must not be revised, modified or operated with parts removed or missing.
Likewise, safety systems must not be circumvented or modified 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.
