SAFETY
INFORMATION

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.

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 work-
ing properly. Get fresh air at once! Have
heater serviced. Some people are more af-
fected by carbon monoxide than others. These
include pregnant women, people with heart or
lung disease or anemia, those under the influ-
ence of alcohol, and those at high altitudes.

Natural Gas:

 Natural gas is 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.

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.

WARNING ICON

G 001

 WARNINGS

 DANGER: Carbon monoxide

poisoning may lead to death!

6.

Do not add extra logs or ornaments
such as pine cones, vermiculite, or rock
wool. Using these added items can
cause sooting.

7.

This log heater is designed to be smoke-
less. If logs ever appear to smoke, turn
off heater and call a qualified service
person. 

Note:

 During initial operation,

slight smoking could occur due to log
curing and heater burning manufactur-
ing residues.

8.

To prevent the creation of soot, follow
the instructions in Cleaning and Main-
tenance, page
 15.

9.

Before using furniture polish, wax, car-
pet cleaners, 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. 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 4 through 6. If
heater keeps shutting off, see Trouble-
shooting,
 pages 16 through 18.

11. Do not run heater

• where flammable liquids or vapors

are used or stored

• under dusty conditions

12. Do not use this stove to cook food or

burn paper or other objects.

13. Do not use heater if any part has been

exposed to or under water. Immediately
call a qualified service technician to in-
spect the room heater and to replace any
part of the control system and any gas
control which has been under water.

14. Do not operate heater if any log is bro-

ken. Do not operate heater if a log is
chipped (dime-sized or larger).

15. Turn heater off and let cool before ser-

vicing. Only a qualified service person
should service and repair heater.

16. Operating heater above elevations of

4,500 feet could cause pilot outage.

 WARNING: Any change to

this heater or its controls can be
dangerous.

 WARNING: Do not allow fans

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

 WARNING: Do not use a

blower insert, heat exchanger
insert or other accessory not ap-
proved 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 heater.

Stove becomes very hot when
