SAFETY
INFORMATION

 DANGER: Carbon monoxide

poisoning may lead to death!

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 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.

 WARNINGS

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.

Before installing in a solid fuel burn-
ing fireplace, the chimney flue and fire-
box must be cleaned of soot, creosote,
ashes, and loose paint by a qualified
chimney cleaner. Creosote will ignite
if highly heated.  Inspect chimney flue
for damage. If damaged, operate heater
with flue damper closed.

5.

If fireplace has glass doors, never op-
erate this heater with glass doors closed.
If you operate heater with doors closed,
heat buildup inside fireplace will cause
glass to burst. Also if fireplace open-
ing has vents at the bottom, you must
open the vents before operating heater.

6.

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

Note

: During ini-

tial operation, slight smoking may
occur due to log curing and heater
burning manufacturing residues.

7.

To prevent the creation of soot, follow
the instructions in Cleaning and Main-
tenance
, page 17.

8.

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.

9.

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 18 through 20.

10. Do not run heater

• where flammable liquids or vapors

are used or stored

• under dusty conditions

11. Do not use this heater to cook food or

burn paper or other objects.

12. 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.

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

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

 WARNING: Any change to

this heater or its controls can be
dangerous.

 WARNING: Do not allow fans

to blow directly into the fireplace.
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.

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

Carefully supervise young chil-
dren when they are in the room
with heater. When using the hand-
held remote accessory, keep se-
lector switch in the OFF position
to prevent children from turning
on burners with remote.

You must operate this heater with
a fireplace screen in place. Make
sure fireplace screen is closed
before running heater.

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