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 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 And Propane/LP Gas: Natural and
Propane/LP gas 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.
WARNING: Do not use a
blower insert, heat exchanger
insert or any accessory not ap-
proved for use with this log set.
WARNING: Do not allow fans
to blow directly into the heater.
Avoid any drafts that alter burner
flame pattern including ceiling
fans. Altered burner patterns
can cause sooting.
WARNING: Any change to
this heater or its controls can
be dangerous.
