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,
people 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 gas.
The odor helps you detect a gas leak. How-
ever, the odor added to gas can fade. 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.

 DANGER: Carbon monoxide

poisoning may lead to death!

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.

 WARNINGS

 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.

If you smell gas
• shut off gas supply
• do not try to light any appliance
• do not touch any electrical switch; do

not use any phone in your building.

• immediately call your gas supplier

from a neighbor’s phone. Follow the
gas supplier’s instructions

• if you cannot reach your gas supplier,

call the fire department

 WARNING: Do not use a

blower insert, heat exchanger
insert, or other accessory not
approved for use with this heater.

4.

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

5.

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 Air For Combustion
and Ventilation,
 pages 5 through 7.

6.

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.

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.

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.

10. To prevent the creation of soot, follow

the instructions in Cleaning and Main-
tenance, 
page 19.

11. Turn off and unplug heater and let cool

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

12. Operating heater above elevations of

4,500 feet could cause pilot outage.

13. To prevent performance problems, do

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

 WARNING: Do not allow fans

to blow directly into the heater.
Avoid any drafts that alter burner
flame patterns. Ceiling fans can
create drafts that alter burner
flame patterns. Altered burner
patterns can cause sooting.

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

Carefully supervise young chil-
dren when they are in same room
with heater.

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

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

Surface of heater becomes very
hot when running heater. Keep
children and adults away from
hot surfaces to avoid burns or
clothing ignition. Fireplace will
remain hot for a time after shut-
down. Allow surfaces to cool be-
fore touching.

Make sure screen is in place be-
fore running heater.
