SAFETY
INFORMATION

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, persons
with heart or lung disease or anemia, those
under the influence of alcohol, and those at
high altitudes.

Propane/LP Gas:

 Propane/LP gas is odor-

less. An odor-making agent is added to
propane/LP gas. The odor helps you detect
a propane/LP leak. However, the odor added
to propane/LP gas can fade. Propane/LP 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.

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

4.

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

5.

Always run non-thermostat heater with
plaque control knob in a locked posi-
tion. Never set control knob between
locked positions. Poor combustion and
higher levels of carbon monoxide may
result.

6.

This heater needs fresh, outside air ven-
tilation to run properly. This heater has
an Oxygen Depletion Sensing (ODS)
safety shutoff system. The ODS shuts
down the heater if not enough fresh air
is available. See Fresh Air for Combus-
tion and Ventilation,
 pages 4 through 6.

7.

Keep all air openings in front and bot-
tom of heater clear and free of debris.
This will insure enough air for proper
combustion.

8.

If heater shuts off, do not relight until
you provide fresh, outside air. If heater
keeps shutting off, have it serviced.

9.

Do not run heater
• where flammable liquids or vapors

are used or stored

• under dusty conditions

10. Before using furniture polish, wax, car-

pet cleaner, or similar products, turn
heater off. If heated, the vapors from
these products may create a white pow-
der residue within burner box or on
adjacent walls or furniture.

11. Do not use heater if any part has been

under water. Immediately call a quali-
fied service technician to inspect the
room heater and to replace any part of
the control system and any gas control
which has been under water.

12. Turn off and unplug heater and let cool

before servicing. Only a qualified service
person should service and repair heater.

13. Operating heater above elevations of

4,500 feet could cause pilot outage.

14. To prevent performance problems, do

not use propane/LP fuel tank of less
than 100 lbs. capacity.

 WARNINGS

poisoning may lead to death!

 WARNING: Any change to this

heater or its controls can be

flammable material on or near
the appliance. Never place any
objects on the heater.

clothing ignition. Heater will re-
main hot for a time after shut-
down. Allow surface to cool be-
fore touching.

dren when they are in the same
room with heater.

Make sure grill guard is in place

appliance should be located out
of traffic and away from furniture
and draperies.
