SAFETY INFORMATION
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.
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, people with heart or lung disease or anemia, those under the
influence of alcohol, and those at high altitudes.
Natural Gas:
Natural gas is odorless. An odor-making agent is
added to the gas. The odor helps you detect a gas leak. However, the
odor added to the gas can fade. Gas may be present even though no
odor exists.

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