CAREFULLY REVIEW THE INSTRUCTIONS SUPPLIED WITH
THE DECORATIVE TYPE UNVENTED ROOM HEATER FOR
THE MINIMUM FIREPLACE SIZE REQUIREMENT.
FOR YOUR SAFETY: Do not store or use gasoline
or other flammable vapors or liquids in the vicinity
of this or any other appliance.
DO NOT INSTALL THE APPLIANCE IN THIS FIREBOX, UN-
LESS THIS FIREBOX MEETS THE MINIMUM DIMENSIONS
REQUIRED FOR THE INSTALLATIONS.
FOR YOUR SAFETY: What to do if you smell gas:
This is an unvented gas-fired heater. It uses air
(oxygen) from the room in which it is installed.
Provisions for adequate combustion and ventila-
tion air must be provided. Refer to Combustion
and Ventilation Air Section, Page 3.
• DO NOT light any appliance.
• DO NOT touch any electrical switches.
• DO NOT use any phone in your building.
• Immediately call your gas supplier from a
neighbor’s phone.
Due to high temperatures, the appliance should be located out
of traffic and away from furniture or draperies.
Follow your gas suppliers instructions.
• If your gas supplier cannot be reached, call the
fire department.
Do not place clothing or other materials on or near this appli-
ance.
Installation and service must be performed by a
qualified installer, service agency or the gas sup-
plier.
IMPORTANT: READ AND UNDERSTAND THESE INSTRUCTIONS
COMPLETELY BEFORE INSTALLING YOUR UNVENTED ROOM
HEATERS.
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 im-
mediately. Have the Unvented Gas Heater
serviced as it may not be operating correctly.
• Ensure that the heater is clean when operat-
ing.Excessivedustaccumulationontheburner
and logs will increase the amount of carbon
monoxide formation and could lead to carbon
monoxide poisoning and death.
Use the following equations to determine if
you have a confined or unconfined space.
1. Determine the volume of space — ft 3.
Length x Width x Height = _____ ft 3
(Includeadjoiningroomswithdoorlesspas-
sageways or ventilation grills between
rooms.)
CODES
• Duetohightemperatures, thefireboxshould
belocatedoutoftrafficandawayfromfurniture
and draperies.
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 The American National Standards Insti-
tute, Inc. (1430 Broadway, New York, NY,
10018) or National Fire Protection Association,
Inc. (Batterymarch Park, Quincy, MA, 02269).
Example: 24' (L) x 16' (W) x 8' (H) = 3072
ft 3
• Children and adults should be alerted to the
hazard of high surface temperature and should
stay away to avoid burns or clothing ignition.
2. Divide the volume of space by 50 ft 3 to
determine the maximum BTU/Hr the space
can support.
• Young children should be carefully super-
vised when they are in the same room with the
heater.

Heaters installed in these appliances shall not
be installed in a confined space. Heaters
installed in these appliances may be located
in unusually tight construction provided the
space is unconfined, or if confined, is pro-
vided with two permanent openings commu-
nicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 1992, Section
5.3). Generally 50 ft 3 per 1,000 BTU input of
all operating appliances in the space.
• Do not place clothing or other flammable
material on or near the heater.
Example: 3072 ft 3 / 50 ft 3 = 61.44
or 61,440 BTU/Hr the space can support.
• Any safety screen or guard removed for
servicing the firebox must be replaced and/or
closed prior to operating the heater.
3. Add the BTU/Hr of all the fuel burning appli-
ances in the space.
• Installation and repair should be done by a
qualified service person. The heater should be
inspected before use and 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
importantthatcontrolcompartments, burners
and circulating air passageways of the heater
be kept clean.

The National Fuel Gas Code defines a confined
space as a space whose volume is less than
50 ft 3 per 1,000 BTU/Hr (4.8 m3 per kw) of the
aggregate input rating of all appliances in-
stalled in that space and an unconfined space
as a space whose volume is not less than 50 ft 3

* Do not include direct-vent gas appliances.
Direct-vent is sealed combustion and draws
combustion air from the outdoors.
• Do not install the firebox in a sleeping room
or bathroom.

The space in the above example is a confined
space because the actual BTU/Hr used is more
than the maximum BTU/Hr the space can sup-
port. You must provide additional fresh air.
• Do not use this heater if any part has been
under water. Immediately call a qualified ser-
vice technician to inspect the heater and to
replace any part of the control system and any
gas control which has been under water.

could prevent the heater from operating reli-
ably.

It is recommended that the ¹⁄₂" gas line enter
the side of the firebox. Connect the gas line
before the firebox is enclosed in the finished
wall. The gas knockout is determined by an
indentation located at the bottom and slightly
offcenterinthesiderefractories. THEKNOCK-
OUT IS ALWAYS REMOVED FROM INSIDE
THE FIREBOX. If removal is attempted from
the outer wrapper, side-refractory damage
may occur. With a medium-sized hammer,
lightly tap the surface of the indentation. The
refractory material is very thin in this area and
is easily removed. Once a small hole has been
made, continuetappinguntilyouhavereached
sufficient diameter for the gas line to fit
through. The entire knockout does not have
to be removed.
Consult installation and operating instructions
for the model of unvented room heater to be
installed.
If your mantel profile is unsafe, you may either:
•
•
Raise the mantel to an acceptable height, or
Remove the mantel.
Checking Gas Connections: Test all gas joints
from the gas meter to the gas heater regulator
for leaks using soap and water solution after
completing connection. DO NOT USE AN OPEN
FLAME.
Floor clearance: These fireplaces may sit
directly on a combustible surface.
ASSEMBLY STEPS
Note: Illustrations shown in this manual re-
flect “typical” installations with nominal di-
mensions and are for design and framing
reference only. Actual installations may vary
due to individual design preferences. How-
ever, always maintain minimum clearances to
combustible materials and do not violate any
specific installation requirements. Refer to the
Framing Specifications Figures on page 8.

The firebox may be installed directly on a com-

appropriate height. Do not place firebox on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, ply-
wood, particle board, metal or other hard sur-
faces which extend the full width and depth of
the enclosure. Be sure firebox rests on a solid
continuous floor or platform with appropriate
framing for support and so that no cold air can
enter room from under the firebox.

and refer to Figures 12, 13 and 14.
Step3.Replacethescrewspreviouslyremoved.
Step 4. Tighten side screws. Make sure the
canopy is level and secure.

Step 3. With the motor shield removed, place
the blower in the unit with the power cord up
and slide to the back of the unit until the motor
is behind the rear support.
Blower Kit
Circulating Models Only
If you are installing one of the blower kits,
Models FBK-100 or FBK 200, follow Steps 1
through 5, and see the installation instructions
provided with the kit for electrical wiring re-
quirements (see Figure 11 ). The firebox must
be connected to main power supply at time of
installation if a forced air kit is to be installed
later. The electrical connections must be made
before the firebox is framed and enclosed in the
finished walls.
Step 4. Rotate the blower 90 degrees, so that
the discharge is up.
Figure 9
Step 5. Move left side of blower around until it
is in the proper position and bend the retaining
tabs in the bottom of the unit up into the slots
on the blower.
Note: The nailing flange and the area directly
behind the nailing flange is exempt from the
clearances described on the firebox clearance
label.

Step 5. To safely operate the heater with con-
sideration of the mantel clearances the canopy
must be installed.
This appliance must be electrically grounded in
accordance with local codes or, in the absence
of local codes, the national electrical code,
ANSI/NFPA 70 - (Latest Edition).
