™
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, persons
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.
