WARNINGS
IMPORTANT: Read this owner’s manual carefully and
completely before trying to assemble, operate, or ser-
vice this heater. Improper use of this heater can cause
serious injury or death from burns, fire, explosion,
electrical shock, and carbon monoxide poisoning.
DANGER: Carbon monoxide poisoning may lead
to death!
Carbon Monoxide Poisoning:
Early signs of carbon monoxide
poisoning resemble the flu, with headaches, dizziness, or nausea. If
you have these signs, the heater may not be working properly. Get
fresh air at once! Have heater serviced. Some people are more
affected by carbon monoxide than others. These include pregnant
women, persons with heart or lung disease or anemia, those under
the influence of alcohol, and those at high altitudes.
Natural and Propane/LP Gas:
Natural and propane/LP gases are
fuel gases. Fuel gases are odorless. An odor-making agent is added
to fuel gases. The odor helps you detect a fuel gas leak. However,
the odor added to fuel gas can fade. Fuel gas may be present even
though no odor exists.

manual for reference. It is your guide to safe and proper operation
of this heater.
