SAFETY
INFORMATION
DANGER: Carbon monoxide
poisoning may lead to death!
Carbon Monoxide Poisoning:
Early
signs of carbon monoxide poisoning re-
semble 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.
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.

the instructions in Cleaning and Main-
tenance, page 19.
10. Do not allow fans to blow directly into

ter burner flame patterns. Ceiling fans
can create drafts that alter burner flame
patterns. Altered burner patterns can
cause sooting.
