IMpORTANT SAFETY INFORMATION

INSTALLER
Please leave these instructions with the appliance.
Any change to this heater or its controls can be dangerous.
Improper installation or use of the heater can cause serious injury or death from
fire, burns, explosion or carbon monoxide poisoning.
Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter
burner flame patterns.
Do not use a blower insert, heat exchanger insert or other accessory, not
approved for use with this heater where applicable.
1. Due to high temperatures, the firebox should be
located out of traffic and away from furniture and
draperies.
. 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 firebox.
4. Do not place clothing or other flammable material
near the fireplace when the firebox is in use.
5. Any safety screen or guard removed for servicing,
must be replaced prior to operating a heater within
the firebox.
6. Installation and repair should be done by a qualified
service person.
7. To prevent malfunction and/or sooting, an unvented
gas heater/firebox should be cleaned at least annu-
ally by a professional service person. More frequent
cleaning may be required due to excessive lint from
carpeting, etc. It is imperative that control compart-
ments, burners and circulating air passageways be
kept clean.
8. 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.
9. The installation must conform with local codes or, in
the absence of local codes, with the National Fuel Gas
Code, ANSI Z3.l/NFPA54.
10. This unit complies with ANSI Z1.91 ventless firebox
enclosures for gas-fired unvented decorative room
heaters.

OWNER
Please retain these instructions for future reference.
13. Correct installation of the ceramic fiber logs, proper
location of the heater, and annual cleaning are neces-
sary to avoid potential problems with sooting. Sooting,
resulting from improper installation or operation, can
settle on surfaces outside the fireplace. See log place-
ment instructions for proper installation.
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 appli-
ances will not filter or clean soot produced by these
types of products. In addition, the smoke and/or aro-
matics (scents) may be reburnt in the vent-free appli-
ance which can produce odors. It is recommended to
minimize the use of candles, incense, etc. while the
vent-free appliance is in operation.
16. An unvented gas-fired heater uses air (oxygen) from
the room in which it is installed. Provisions for adequate
combustion and ventilation air must be provided. See
installation guidelines.
17. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors and
liquids.
18. Unvented gas heaters are a supplemental zone heater.
They are not intended to be a primary heating appli-
ance.
19. Unvented gas heaters emit moisture into the living
area. In most homes of average construction, this
does not pose a problem. In houses of extremely
tight construction, additional mechanical ventilation is
recommended.
0. 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
as they are burned off during the initial operation of the
appliance; possibly causing headaches, or eye or lung
irritation. This is a normal and temporary occurrence.
