Improper use of this fireplace
can cause serious injury or death
from burns, fire, explosion,
electrical shock, and carbon
monoxide poisoning.
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 fireplace may not
be working properly. Get fresh air at once!
Have fireplace 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 and Propane/LP Gas:
Natural and
propane/LP gases are 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.
