WARNINGS

IMPORTANT: Read this owner’s manual carefully and
completely before trying to assemble, operate, or ser-
vice this heater. Improper use of this heater can cause
serious injury or death from burns, fire, explosion,
electrical shock, and carbon monoxide poisoning.

 DANGER: Carbon monoxide poisoning may lead

to death!

 WARNING: Any change to this heater or its

controls can be dangerous.

1.

This appliance is only for use with the type of gas indicated on
the rating plate. This appliance is not convertible for use with
other gases.

2.

Do not place propane/LP supply tank(s) inside any structure.
Locate propane/LP supply tank(s) outdoors.

3.

This heater shall not be installed in a bedroom or bathroom.

Do not place clothing or other flammable material on
or near the appliance. Never place any objects on the
heater.

Surface of heater becomes very hot when running
heater. Keep children and adults away from hot sur-
face to avoid burns or clothing ignition. Heater will
remain hot for a time after shutdown. Allow surface to
cool before touching.

Carefully supervise young children when they are in
the same room with heater.

Make sure grill guard is in place before running
heater.

Keep the appliance area clear and free from combus-
tible materials, gasoline and other flammable vapors
and liquids.

 WARNING: Do not use any accessory not ap-

proved for use with this heater.

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, 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

fuel gases. Fuel gases are odorless. An odor-making agent are added
to fuel gases. The odor helps you detect a fuel gas leak. However,
the odor added to fuel gas can fade. Fuel 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.

Due to high temperatures, the appliance should be
located out of traffic and away from furniture and
draperies.
