Operating & Safety Precautions; Operating Instructions - DeWalt DXH70KTFRHC Instruction Manual

Operating Precautions
This is a kerosene, direct-fired, radiant 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 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.
Safety Precautions
THIS IS A HEATING APPLIANCE. DO NOT ATTEMPT TO WARM OR COOK
FOOD ON THIS HEATER.

openings as marked for each additional heater.
6. Always keep combustibles, like paper and wood at least 8 ft. from the heater
outlet and 3' from the top, sides and inlet. Locate 8 ft. from canvas or plastic
coverings and secure them to prevent flapping movement.
7. Caution: Due to the high surface and exhaust temperatures, adults and children
must observe clearances to avoid burns or clothing ignition. Do Not Touch. Keep
children, clothing, and combustible away.
