OWNER
Please retain these instructions for future reference.
1. Due to high temperatures, the appliance should be
located out of traffic and away from furniture and
draperies.
2. Children and adults should be alerted to the hazard
of high surface temperature and should stay away
to avoid burns or clothing ignition.
3. Young children should be carefully supervised when
they are in the same room with the appliance.

on or near the appliance.
5. Any safety screen or guard removed for servicing
an appliance, must be replaced prior to operating
the heater.
6. Installation and repair should be done by a qualified
service person. To prevent malfunction and/or soot-
ing, an unvented fireplace should be cleaned before
use and at least annually by a professional service
person. More frequent cleaning may be required
due to excessive lint from carpeting, bedding mate-
rials, etc. It is imperative that control compartments,
burners and circulating air passageways be kept
clean.
7. WARNING! Any change to this heater or its controls
can be dangerous.
8. Unvented fireplaces are a supplemental zone
heater. They are not intended to be the primary
heating appliance.
9.
CARBON MONOXIDE POISONING:
Early signs of
carbon monoxide poisoning are similar to the flu with
headaches, dizziness and/or nausea. If you have these
signs, obtain fresh air immediately. Have the heater
serviced as it may not be operating properly.
10. The installation must conform with local codes or, in
the absence of local codes, with the
National Fuel
Gas Code, ANSI Z223.l/NFPA54.
11. This unit complies with ANSI Z21.11.2:19
Unvented
Heaters
.
12. Do not install the heaters in a bathroom or bedroom.
13. Proper location of the heater, and annual cleaning are
necessary to avoid potential problems with sooting.
Sooting, resulting from improper installation or opera-
tion, can settle on surfaces outside the fireplace.
14. Avoid any drafts that alter burner flame patterns. Do not
allow fans to blow directly into fireplace. Do not place
a blower inside burn area of firebox. Ceiling fans may
create drafts that alter burner flame patterns. Sooting
and improper burning will occur.
15.
Caution:
Candles, incense, oil lamps, etc. produce
combustion byproducts including soot. Vent-free
appliances will not filter or clean soot produced by
these types of products. In addition, the smoke and/or
aromatics (scents) may be re-burned in the vent-free
appliance which can produce odors. It is recommended
to minimize the use of candles, incense, etc. while the
vent-free appliance is in operation.
16. This is an unvented fireplace. It uses air (oxygen) from
the room in which it is installed. Provisions for adequate
combustion and ventilation air must be provided. Refer
to
Page 8.
17. This heater shall not be installed in a room or space
unless the required volume of indoor combustion air is
provided by the method described in the
National Fuel
Gas Code, ANSI Z223.1/NFPA 54
, the
International
Fuel Gas Code
or applicable local codes.
18. Keep room area clear and free from combustible mate-
rials, gasoline and other flammable vapors and liquids.
19. Unvented fireplaces emit moisture into the living area.
In most homes of average construction, this does not
pose a problem. In houses of extremely tight con-
struction, additional mechanical ventilation is recom-
mended.
20. During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain
oils, films or bonding agents. These chemicals are not
harmful but may produce annoying smoke and smells
