WARNING: Any change to this heater or its

patterns. Ceiling fans can create drafts that alter
burner flame patterns. Altered burner patterns can
cause sooting.

exchanger insert, or other accessory not approved
for use with this heater.
Due to high temperatures, the appliance should be
located out of traffic and away from furniture and
draperies.
Do not place clothing or other flammable material on
or near the appliance. Never place any objects on the

Surface of heater becomes very hot when running

Carbon Monoxide Poisoning: Early signs of carbon monoxide
poisoning resemble the flu, with headaches, dizziness, or nausea.

Get fresh air at once! Have heater serviced. Some people are
more affected by carbon monoxide than others. 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.

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