WARNING ICON

G 001

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

: Natural gas is odorless. An odor-making agent is added to natural gas.

The odor helps you detect a natural gas leak. However, the odor added to natural gas
can fade. Natural gas may be present even though no odor exists.

Make certain you read and understand all warnings. Keep this manual for reference.
It is your guide to safe and proper operation of this heater.
