INSTALLATION
The Model FP-BR10-ZC Vent-Free gas fireplace may be installed in any
room in a Residential home or an After-Market* Manufactured Home.
(Exception: This appliance may not be installed in a bathroom.)
* (After Market: Completion of sale, not for the purpose of resale from the manufacturer).
For After-Market Manufactured Home installation, check with state and 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.
NOTE: See page 14 for “Producing Adequate Ventilation”.
CHOOSING THE LOCATION FOR YOUR FIREPLACE:
Figure 1 shows some of the many ways your fireplace may be installed. Consider the traffic pattern in
your room and the location of doors and windows. Moving air from ceiling fans, open doors, and hot air
grills may cause the flames to soot. If a disturbance is found that affects the flames, it must be
eliminated by turning off the ceiling fan, closing the door, or closing or moving the hot air register. A
corner location may be best where space is limited.
Your fireplace weighs no more than some of your fine furniture. If the fireplace is located near a load
bearing wall, additional supports to the foundation will not be necessary. HEAVY FACINGS, SUCH
AS BRICK, STONE, ETC., MAY REQUIRE ADDITIONAL FOUNDATION SUPPORT.
NOTE: If this appliance is installed directly on carpeting, tile or other combustible material, other
than wood flooring, the appliance shall be installed on a metal or wood panel extending the full
width and depth of the appliance.
GAS LINES
The gas supply line and electrical supply must
be installed before framing in the fireplace by
a licensed installer.
DRAFTS
Do not locate the fireplace in high traffic areas
or areas exposed to high drafts and winds.
Locate the fireplace away from furniture and
draperies.

This list of specific instructions will help you make certain that
every installation operation is performed correctly. Complete the
installation steps in the sequence shown. STATE AND LOCAL
BUILDING CODES SHOULD BE CONSULTED IN ALL
CASES AS TO THE PARTICULAR REQUIREMENTS
CONCERNING THE INSTALLATION OF A FACTORY
BUILT FIREPLACES. Select the location for the fireplace by
taking into consideration the factors previously outlined in the
“Choosing the Location.” See page 5.
Framing the Firebox
The width of the framed opening must be 26 1/8". The height of
the framed opening must be 25 1/8". The entire fireplace can be
elevated above the floor to achieve a raised hearth effect. This can
be done by adding a small platform to achieve the desired height.
NOTE: The wiring for the lower blower must be installed during
the framing stage. The nailing flanges on both sides were designed
to allow the installation of 1/2" wallboard or plywood flush with
the face of the fireplace.
When the framing is inside, the outside wall will be insulated. If
the framing or chase is outside, thin insulation should be used in the
framing on the back, sides, and top. The bottom should be
insulated with a hard insulating board. This will prevent cold from
going into the chase through the fireplace to the living space.
Install the Firebox
Install the firebox into the framed opening by placing it directly in
front of the opening and sliding it into the proper position.
Level the Firebox
Check the level of the firebox on the top edge of the fireplace face.
Shim if necessary.
Secure the Firebox
Secure the fireplace to the framing. The nailing flanges on the
firebox will make securing the firebox to the frame quick and easy.
Use appropriate size nails or screws to secure the firebox.
FIREPLACE CLEARANCES
The fireplace may be placed directly on a combustible floor, against
a combustible wall at marked clear-ances, or on a raised wooden
platform.
If the fireplace is to be installed on a raised wooden platform, the
platform must be a continuous level surface. The fireplace must be
secured in place so it cannot shift positions. The nailing flanges on
the sides of the firebox make securing it to the framing easy. They
were designed to allow the installation of 1/2" wallboard or plywood
flush with the face of the fireplace.
Only the header (see Figure 2) may rest on the stand-offs on top of
the firebox.
When the firebox is installed over carpeting, (vinyl) tile,or any
combustible material other than wood flooring, it must be
installed on a metal or wood panel extending its full width and
depth. Alternatively, the carpeting, (vinyl) tile, etc. may be
removed beneath the fireplace before installing.
COMBUSTIBLE MATERIALS MUST NOT BE
INSTALLED OVER OR TOUCH ANY BLACK
PAINTED SURFACE. DO NOT BLOCK HEAT
CIRCULATING AIR OUTLETS. DOING SO MAY
RESULT IN POTENTIAL FIRE HAZARDS.
1. Sidewall Clearances: Clearances from the side of the
fireplace opening to any adjacent combustible wall should
not be less than 7".
2. Ceiling Clearances: The ceiling height should
not be less than 42" from the top of the fireplace
opening.

There is a wide variety of finishing material available
for your fireplace from formal wall treatments with
marble and mantels, to rustic wood paneling, stone or
brick. Non-Combustible materials used in this
installation such as slate, tile, marble, etc. must be at
least 1/2" thick.
IT IS IMPORTANT THAT THE BLACK FACE OF
THE FIREPLACE NOT BE COVERED WITH
ANY TYPE OF COMBUSTIBLE MATERIAL.
Non-combustible facing materials such as marble, brick,
or ceramic tile may overlap the black face of the
fireplace up to the opening on either side of the
fireplace. Seal all joints between the black fireplace face
and the wall covering with a heat-resistant material such
as rock wool insulation or mortar. Be sure to use high
temperature adhesive or mortar when anchoring brick,
stone, or tile to the face of the fireplace.
CLEARANCES
To ensure a safe installation, the following must be
carefully observed.
1. Sidewall Clearances: Clearances from the right or
left side of the fireplace opening to any adjacent
combustible wall should not be less than 7", facing the
unit.
2. Ceiling Clearances: The ceiling height should not
be less than 42" from the top of the fireplace opening.
Check to see whether man-made brick and stone are
made of non combustible materials before using them
on the face of the fireplace. Some of these products
contain combustible materials. Combustible wall
coverings such as paneling or wallboard may not
overlap the black face of the fireplace. The space
between the wall covering and the fireplace should be
sealed with a heat resistant material such as rock wool
insulation or mortar.
NOTE: An “L” shaped steel lintel must be installed
across the top of the firebox opening where facing
materials such as brick or stone is used on the face of
the firebox. It acts as a support/firestop. It should be
attached to the face of the fireplace with screws and
sealed to the fireplace with a heat-resistant sealer.
3. Mantel Clearances: We have provided 4 different
situations to position your mantel. See Figure 5.
4. Floor Clearances: No clearance is required if the
appliance is installed per these instructions.

Page 13

PRODUCING ADEQUATE
VENTILATION
This section is for residential or manufactured (mobile) installation
“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/NFPA 54 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 (4.8m 3 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.
“WARNING: 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/
NFPA 54, SECTION 5.3 OR APPLICABLE LOCAL CODES.”
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;
b) Weather stripping has been added on openable windows and doors, and
c) Caulking or sealants are applied to areas such as joints around window 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.
NOTE: SOME AREAS IN THE UNITED STATES HAVE HIGHER REQUIREMENTS
FOR CUBIC FEET PER 1000 BTU/ HOUR INPUT. (EX. CINCINNATI, OHIO CODES
REQUIRE 70 CUBIC FEET). CHECK YOUR LOCAL CODE BEFORE
INSTALLATION.
Page 14

DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
DETERMINE IF YOU HAVE A CONFINED OR UNCONFINED SPACE
Use this worksheet to determine if you have confined or unconfined space.
SPACE: Includes the room in which you will install heater plus adjoining rooms with
doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space (length x width x height).
Length x Width x Height =_________cu.ft.(volume of space)
EXAMPLE: 20 ft.(Length) x 16 ft.(Width) x 8 ft.(ceiling Height)=
2560 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills or openings, add the
volume of these rooms to the total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the maximum BTU/Hr the
space can support.
_________(volume of space)/50 cu. ft. =maximum BTU/Hr the space can support)
EXAMPLE: 2560 cu. ft. (volume of space /50 cu. Ft .= 51.2 or
51200 (maximum BTU/Hr the space can support)
3. Add the BTU/Hr of all fuel burning appliances in the space.
Vent-free heater _______________BTU/Hr
Gas water heater* _______________BTU/Hr
Gas furnace _______________BTU/Hr
Vented gas heater _______________BTU/Hr
Gas fireplace logs _______________BTU/Hr
Other gas appliances* + _______________BTU/Hr
Total = _______________BTU/Hr
Example: Gas water heater 40000 BTU/Hr
Vent-free heater + 18000 BTU/Hr
Total = 58000 BTU/Hr
*Does not include direct-vent gas appliances. Direct-vent draws combustion air
from the outdoors and vents to the outdoors.
4. Compare the maximum BTU/Hr the space can support with the actual amount of BTU/Hr
used.
____________BTU/Hr (maximum the space can support)
____________BTU/Hr (actual amount of BTU/Hr used)
Example: 51200 BTU/Hr (maximum the space can support)
58000 BTU/Hr (actual amount of BTU/Hr used)
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 support. You must provide additional fresh
air. Your options are as follows:
Page 15

VENTILATION AIR
VENTILATION AIR FROM INSIDE BUILDING
This fresh air would come from an adjoining unconfined space. When venting to an adjoining space,
you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the
floor on the wall connecting the two spaces. (See Options 1 and 2, Figure 7.) You can also remove door
into adjoining room. (See Option 3, Figure 7.)
WA R N I N G
REWORK WORKSHEET, ADDING THE SPACE OF THE ADJOINING UNCONFINED
SPACE. THE COMBINED SPACES MUST HAVE ENOUGH FRESH AIR TO SUPPLY ALL
APPLIANCES IN BOTH SPACES.
NOTE: Each opening shall have a minimum free area of 1 square inch per 1000 BTU’s per hour of the
total input ratings of all gas utilization equipment in the confined space, but not less than 100 square
inches.
Figure 7 Ventilation Air From Inside Building
A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an
unconfined space, remove door to adjoining room or add ventilation grills between rooms. See
“Ventilation Air From Inside Building”, page 21.
B. Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 22.
C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes room unconfined.
If the actual BTU/Hr used is less than the maximum BTU/Hr the space can support, the
space is an unconfined space. You will need no additional fresh air ventilation.
WA R N I N G : YOU MUST PROVIDE ADDITIONAL VENTILATION AIR IN A
CONFINED SPACE
Page 16

VENTILATION AIR FROM OUTDOORS
Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent
openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items
directly to the outdoors. These spaces include attics and crawl spaces. Follow the National
Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, “Air For Combustion and Ventilation” for
required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet air into attic if attic has a thermostat-
controlled power vent. Heated air entering the attic will activate the power unit.
WARNING
THIS HEATER MUST HAVE FRESH AIR FOR PROPER OPERATION. IF NOT,
POOR FUEL COMBUSTION COULD RESULT. READ THE FOLLOWING
