SAFETY WARNINGS CONTINUED

⚠️WARNING! Risk of indoor air pollution.
The products described in this manual are propane direct-fired, forced air heaters. Propane forced air heaters are primarily intended for use for temporary heating of buildings under construction, alteration or repair. Direct-fired means that all of the combustion products of the heater enter the heated space. This appliance is rated at 98% combustion efficiency, but does produce small amounts of carbon monoxide.
⚠️DANGER! Carbon monoxide poisoning may lead to death.
Carbon monoxide is toxic. Humans can only tolerate small amounts of carbon monoxide, so precautions must be taken to provide proper ventilation. Failure to provide proper ventilation in accordance with the following instructions can result in death.
People with breathing problems should consult a physician before using this heater. Early signs of carbon monoxide poisoning resemble the flu. Symptoms of improper ventilation/carbon monoxide poisoning are headache, dizziness, nausea, dry mouth, sore throat and burning of nose and eyes.
If you experience any of these symptoms, get fresh air at once. Have your heater serviced and check for proper ventilation. Some people are affected by carbon monoxide more than others. These include pregnant women, those with heart or lung problems, anemia or those under the influence of alcohol or at high altitudes.
For outdoor use. Indoor use permitted only for temporary heating of adequately ventilated buildings or structures under construction, alteration or repair. Provide at least a three square foot opening of outside air for every 100,000 BTU/HR heater rating. Refer to Ventilation on page 6 for instructions.

OPERATION

PROPANE SUPPLY
PROPANE
This heater is not supplied with a propane cylinder. Use only an approved propane cylinder.
LP CHARACTERISTICS

Flammable, explosive under pressure, heavier than air and pools in low areas.
