SAFETY

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 oth-
ers. 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.
