IMPORTANT SAFETY INFORMATION
INSTALLER
Please leave these instructions with the owner.
Please retain these instructions for future reference
OWNER
IMPORTANT
Read these instructions carefully before installing or trying to operate this vent-free gas heater.
• 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 drafts that alter burner flame
patterns.
• Do not use a blower insert, heat exchanger insert or other accessory, not approved for
WARNING
1. Due to high temperatures, the heater 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 heater
4. Do not place clothing or other flammable material near the fireplace when the heater is in use.
5. Any safety screen or guard removed for servicing, must be replaced prior to operating the
heater.
6. Installation and repair should be done by a qualified service person.
7. To prevent malfunction and/or sooting, an
unvented gas heater should be cleaned at least
annually by a professional service person. More
frequent cleaning may be required due to excessive lint from carpeting, etc. It is imperative
that control compartments, 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.
use with this heater where applicable.
9. The installation must conform with local codes or,
in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.l.
10. This unit complies with ANSI Z21.11.2a-1997
Unvented Heaters and also complies with ANSI
Z21.60-1991 Decorative Vented Appliances for
Solid Fuel Burning Fireplaces. State and local
codes may only allow operation of this appliance
in a vented configuration. Check your state or local codes. For vented operation, see "Vented Instructions" in this manual.
11. Do not install the heaters in a bathroom or bedroom.
12. Correct installation of the ceramic fiber logs,
proper location of the heater an annual cleaning
are necessary to avoid potential problems with
sooting. Sooting, resulting from improper installation or operation, can settle on surfaces outside
the fireplace. See log placement instructions for
proper installation.
13. 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.
14. This is an unvented gas-fired heater. It uses air
(oxygen) from the room in which it is installed.
Provisions for adequate combustion and ventilation air must be provided. Refer to installation
guidelines.

IMPORTANT SAFETY INFORMATION
15. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors and
liquids.
16. Unvented gas heaters are a supplemental zone
heater. They are not intended to be a primary heating appliance. Water vapor produced by an
unvented heater can create moisture problems in a
home when operated for extended periods of time.
17. 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 of f during
the initial operation of the appliance; possibly causing headaches or eye or lung irritation. This is a
normal and temporary occurrence.
The initial break-in operation should last 2-3 hours
with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to
allow odors to dissipate. Any odors remaining after this initial break-in period will be slight and will
disappear with continued use.
23. Never burn solid fuels in a fireplace where a
unvented room heater is installed.
24. Always have a fireplace screen in place when the
appliance is in operation and , unless other provisions for combustion air are provided, the screen
shall have an opening(s) for induction of combustion air.
This appliance may be installed in an
aftermarket, permantly located, manufactured
(mobile) home, where not prohibited by local
codes.
This appliance is only for use with the type of
gas indicated on the rating plate. This appliance is not convertible for use with other gases.
18. Input ratings are shown in BTU per hour and are
for elevations up to 2,000 feet. For elevations above
2,000 feet, input ratings should be reduced 4 percent for each 1,000 feet above sea level. Refer to
the National Fuel Gas Code.
19. The heater and its individual shutoff valv e must be
disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of 1/2 psig (3.5 kPa).
20. The heater must be isolated from the gas supply
piping system by closing its individual manual
shutoff valv e during any pressure testing of the gas
supply piping system at test pressures equal to or
less than 1/2 psig (3.5 kPa).
21. Do not use this room heater if any part has been
under water. Immediately call a qualified service
technician to inspect the room heater and to replace
any part of the control system and any gas control
which has been under water.
22. This appliance must not be used with glass doors
in the closed position. This can lead to pilot outages and severe sooting outside the fireplace.

GENERAL INSTALLATION INFORMATION
Pilot - The gas log heater is fitted with a specially designed safety pilot light which senses the
amount of oxygen available in the room and shuts the gas log heater off if the oxygen
level be gins to drop below a satisfactory le vel. The pilot can only be relit when adequate
fresh air is available.

CODES
Adhere to all local codes, or in their absence, the latest edition of THE NATIONAL FUEL GAS
CODE ANSI Z223.1 or NFPA54 which can be obtained from:

This heater shall not be installed in a confined space or unusually tight construction unless provisions
are provided for adequate combustion and ventilation air.
The National Fuel Gas Code ANSI Z223.1 defines a confined space as a space whose volume is less
than 50 cubic feet per 1,000 Btu per hour (4.8m
3
per kw) of the aggregate input rating of all appliances
installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet
per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that
space. Rooms communicating directly with the space in which the appliances are installed, through
openings not furnished with doors, are considered a part of the unconfined space.
Unusually tight construction is defined as construction where:
a) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with
a rating of 1 perm (6 x 10
-11
kg per-pa-sec-m2) or less with openings gasketed or sealed, and
b) Weather stripping has been added on openable windows and doors, and
c) Caulking or sealant are applied to areas such as joints around windows and door frames, between
sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

The following formula can be used to determine the maximum heater rating per the definition of unconfined space:
Btu/Hr =
(L1 + L2)FT x (W)FT x (H)FT
x 1000

Example: Refer to Figur e 1, tw o (2) connecting rooms with an open area between, with the following

If there was a door between the two rooms the calculation would be based only on the room with the
heater:
If the area in which the heater may be operated is smaller than that defined as
an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described
in the National Fuel Gas Code, ANSI Z223.1, Section 5.3 or applicable local
codes.
