volt ignition system. The fireplace in-
cludes a manual variable blower and an

dard factory setup is for natural gas. See

10. You must keep control compartments,

burners, and circulating air passages

needed due to excessive lint and dust
from carpeting, bedding material, pet
hair, etc. Turn off the gas valve and pi-
lot light before cleaning fireplace.

11. Have venting system inspected annu-

ally by a qualified service person. If

ance for servicing and proper operation.

peting, vinyl tile, or any combustible ma-
terial other than wood. The fireplace must

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

 WARNING: Any change to

this fireplace or its controls can
be dangerous.

 WARNINGS

 DANGER: Carbon monoxide

poisoning may lead to death!

This fireplace is a vented product. This
fireplace will not produce any gas leakage
into your home if properly installed. This
fireplace must be properly installed by a
qualified service person. The glass door
must be properly seated and sealed. If this
unit is not properly installed by a qualified
service person with glass door properly
seated and sealed, gas leakage can occur.

Carbon Monoxide Poisoning:

 Early signs

of carbon monoxide poisoning resemble the
flu, with headaches, dizziness, or nausea. If
you have these signs, the fireplace may not
have been installed properly. Get fresh air
at once!
 Have fireplace inspected and ser-
viced by a qualified service person. Some
people are more affected by carbon monox-
ide 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 and natural gas are both
odorless. An odor-making agent is added to
each of these gases. The odor helps you
detect a gas leak. However, the odor added
to these gases 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 fireplace.
