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.

Natural Gas:

 Natural gas is odorless. An

odor-making agent is added to natural gas.
The odor helps you detect a natural gas leak.
However, the odor added to natural gas can
fade. Natural 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.

3.

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

4.

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

5.

This heater needs fresh, outside air ven-
tilation to run properly. This heater has
an Oxygen Depletion Sensor (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.

6.

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

7.

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

8.

Do not run heater
• where flammable liquids or vapors

are used or stored

• under dusty conditions

9.

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.

10. 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.

11. Turn off and unplug heater and let cool

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

12. Operating heater above elevations of

4,500 feet could cause pilot outage.
