SAFETY
INFORMATION
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 work-
ing properly. Get fresh air at once! Have
heater serviced. Some people are more af-
fected by carbon monoxide than others. These
include pregnant women, people with heart or
lung disease or anemia, those under the influ-
ence 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.

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