It is suggested that you wear work gloves and safety glasses to protect your hands and eyes when
installing your fireplace. NOTE: Authorities having jurisdiction (i.e. building inspectors, fire marshals, etc.)
should be consulted before installation to determine the need to obtain a permit.
These fireboxes are approved as universal fireboxes and can be paired with any ANSI Z21.11.2
approved vent free gas log set. The vent free log manufacturer’s instructions, including their
required dimensional clearances for firebox size, must be followed.
Refer to the manual that is packed with the log set for operating instructions.
General Installation Information
In planning the installation for the appliance it is necessary to determine where the unit is to be installed
and whether optional accessories are desired. Gas supply piping should also be planned. The following
steps represent the normal sequence of installation. Each installation is unique, however, and might
require a different sequence.
1. Position firebox prior to framing or into prepared framing.
2. Plumb gas line. (Gas connections should only be performed by an experienced,
licensed/certified tradesman).
3. Install vent-free gas log heater per the instructions provided with the vent-free gas log heater.
4. Complete finish wall material, surround and optional hearth extension to your individual taste.

Safety Information
IMPORTANT
Read these instructions carefully before
installing or trying to operate a vent-free gas heater in
this firebox.
• 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.
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.
4. Do not place clothing or other flammable material 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.
7. To prevent malfunction and/or sooting, an unvented
gas heater should be cleaned before use at least
annually by a professional service person.
More frequent cleaning may be required due to
excessive lint from carpeting, bedding material,
etc. It is imperative that control compartments,
burners and circulating air passages be kept clean.
10. This unit complies with ANSI Z21.91.2001 ventless
firebox enclosures for gas-fired unvented
decorative room heaters.
11. Do not install heater in a bathroom or bedroom.
12. Correct installation of the logs, proper location of
the heater, and 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. Candles, incense oil lamps, etc.
produce combustion byproducts including soot.
Vent-free appliances will not filter or clean soot
produced these types of products. In addition, the
smoke and/or aromatics (scents) may be reburnt
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.
15. 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.
16. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors
and liquids.
17. Unvented gas heaters are a supplemental zone
heater. They are not intended to be a primary
heating appliance.
18. 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.
CARBON MONOXIDE POISONING: Early signs of
8.
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
Gas Code, ANSI Z223.1/NFPA54.

Safety Information
19. 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.
The initial break-in operation should last two to
three 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 continual use.
20. 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% for each 1,000 feet above sea level. Refer to
the National Fuel Gas Code.
21. The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
systems during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5kPa).
22. The appliance must be isolated from the gas
supply piping system by closing its equipment
shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 kPa).
23. 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.
24. Never burn solid fuels in a fireplace where an
unvented room heater is installed.
25. Always have a fireplace screen n 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.
26. Do not fill spaces around the firebox with
insulation or other materials. These spaces must
be maintained to prevent the firebox from coming
in contact with combustible materials.
