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.
SECTION II
ZERO CLEARANCE INSTALLATION

Page 7

FIREPLACE CLEARANCES
The fireplace may be placed directly on a combustible
floor, against a combustible wall at marked clearances, 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 standoffs
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"right side, 7” left side.
2. Ceiling Clearances: The ceiling height should
not be less than 42" from the top of the fireplace
opening.
INSTALLING THE FIREBOX
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.
LOCAL BUILDING CODES SHOULD BE CONSULTED IN ALL CASES AS
TO THE PARTICULAR REQUIREMENTS CONCERNING THE
INSTALLATION OF FACTORY BUILT FIREPLACES. Select the location
for the fireplace by taking into consideration the factors previously
outlined in the “Choosing the Location.” See page 6.
Framing the Firebox
The width of the framed opening must be 31 7/8". The height of the
framed opening must be 32 3/16". 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.

FINISHING YOUR FIREPLACE
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. 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.
CLEARANCES
To ensure a safe installation, the following
must be carefully observed.
1. Sidewall Clearances: Clearances from
the side of the fireplace opening to any
adjacent combustible wall should not be less
than 7"right side, 7” left side. See Figure 4.
2. Ceiling Clearances: The ceiling height
should not be less than 42" from the top of the
fireplace opening.
3. Mantel Clearances: We have provided 3
different situations to position your mantel.

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 pro-
visions are 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.
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.
Page 14

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: 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 16.
B. Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 17.
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.
WARNING: YOU MUST PROVIDE ADDITIONAL VENTILATION AIR IN A
CONFINED SPACE
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).
WARNING
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
Page 16

FIGURE 8
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 APPLIANCE MUST HAVE FRESH AIR FOR PROPER OPERATION. IF NOT,
POOR FUEL COMBUSTION COULD RESULT. READ THE FOLLOWING

GAS CONNECTION
Check gas type. Use only the type of gas indicated on the valve rating plate. If the gas type listed on
the plate is not your type of gas supply, DO NOT INSTALL. Contact your dealer for proper model.
Always use an external regulator for all LP heaters to reduce the supply tank pressure to a maximum
of 13" W.C. This is in addition to the regulator furnished with the heater.
WARNING: CONNECTION DIRECTLY TO AN UNREGULATED LP TANK CAN
CAUSE AN EXPLOSION.
The normal gas connection is 3/8" N.P.T. made at the left side (facing the front of the appliance) of
the appliance. If a right side connection is desired, the connecting pipe may be led under the rear of
the burner base to terminate at the right side for connection to the inlet of the valve.
NOTE: The connecting pipe must be internally tinned copper tubing for use with natural gas. Test
for leaks using a solution of soap and water after completing the connection. DO NOT USE OPEN
FLAME.
NOTE: “If the factory-built fireplace has no gas access hole(s) provided, an access hole of 1.5 inch
(37.5mm) diameter or less may be drilled through the lower sides or bottom of the fire box in a proper
workmanlike manner. This access hole must be plugged with non-combustible insulation after the gas supply
line has been installed.”
WARNING: Installation and repairs should be performed by a qualified service person. The appli-
ance should be inspected before use and at least annually by a professional service person. More fre-
quent cleaning may be required due to excessive lint from carpeting, bedding material, etc. It is im-
perative that control compartments, burners and circulating air passageways of the appliance be kept
clean.
