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, people with
heart or lung disease or anemia, those under the influence of alcohol, and those at high
altitudes.

: 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.
