PLANNING  
Plan where you will install the firebox. This will  
save time and money later when you install  
the firebox. Before installation, consider the  
following:  
Internal wall installation provides a  
discreet viewing option between two  
adjacent rooms or within an added wall  
to subdivide an oversize room.  
1. Where the firebox will be located.Allow for  
wall and ceiling clearances (see Installa-  
tion Clearances, page 9).  
2. Everything needed to complete installation.  
3. This model CANNOT be installed in a  
bedroom or bathroom.  
4. Proper air for combustion and ventilation.  
5. Consider a location where heat output  
would not be affected by drafts, air condi-  
tion ducts, windows or doors.  
6. A location that minimizes modifications  
on existing framing will make installation  
easier.  
Projected installations can extend any  
distance into the room. A projection may  
be ideal as a partition between two oth-

AiR FOR COMBUSTiON AND VENTiLATiON  
Unusually Tight Construction  
WARNING: This heater shall  
not be installed in a room or  
space unless the required vol-  
ume of indoor combustion air  
is provided by the method de-  
scribed in the National Fuel Gas  
Code,ANSI Z223.1/NFPA54, the  
International Fuel Gas Code, or  
applicablelocalcodes.Readthe  
following instructions to insure  
proper fresh air for this and  
other fuel-burning appliances  
in your home.  
The air that leaks around doors and windows  
may provide enough fresh air for combustion  
and ventilation. However, in buildings of un-  
usually tight construction, you must provide  
additional fresh air.  
Unusually tight construction is defined as  
construction where:  
a. walls and ceilings exposed to the out-  
side atmosphere have a continuous  
water vapor retarder with a rating of one  
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 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.  
Today’s homes are built more energy efficient  
than ever. New materials, increased insulation  
and new construction methods help reduce  
heat loss in homes. Home owners weather  
strip and caulk around windows and doors  
to keep the cold air out and the warm air in.  
During heating months, home owners want  
their homes as airtight as possible.  
If your home meets all of the three criteria  
above, you must provide additional fresh  
air. See Ventilation Air From Outdoors,  
page 8.  
While it is good to make your home energy  
efficient, your home needs to breathe. Fresh  
air must enter your home. All fuel-burning ap-  
pliances need fresh air for proper combustion  
and ventilation.  
If your home does not meet all of the three  
criteria above, proceed to Determining  
Fresh-Air Flow for Firebox Location,  
page 7.  
Exhaustfans, fireboxes, clothesdryersandfuel  
burning appliances draw air from the house to  
operate. You must provide adequate fresh air  
for these appliances. This will insure proper  
venting of vented fuel-burning appliances.  
Confined and Unconfined Space  
The National Fuel Gas Code ANS Z223.1/  
NFPA54 defines a confined space as a space  
whose volume is less than 50 cubic feet per  
1,000 Btu/hr (4.8 m3 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/hr (4.8 m3 per kw) of the ag-  
gregate 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 un-  
confined space.  
PROVIDING ADEQUATE  
VENTILATION  
The following are excerpts from National  
Fuel Gas Code ANS Z223.1/NFPA 54,Air for  
Combustion and Ventilation.  
All spaces in homes fall into one of the three  
following ventilation classifications:  
1. Unusually Tight Construction  
2. Unconfined Space  
3. Confined Space  
This heater shall not be installed in a confined  
space or unusually tight construction unless  
provisions are provided for adequate combus-  
tion and ventilation air.  
The information on pages 6 through 8 will help  
you classify your space and provide adequate  
ventilation.  
* Adjoining rooms are communicating only if  
there are doorless passageways or ventilation  
grills between them.

Unconfined Space  
_______ Btu/Hr (maximum the space can  
support)  
Use this work sheet to determine if you have  
a confined or unconfined space.  
_______ Btu/Hr (actual amount of Btu/Hr  
used)  
Space: Includes the room in which you will  
install heater plus any adjoining rooms with  
doorless passageways or ventilation grills  
between the rooms.  
Example: 63,360 Btu/Hr (maximum the  
space can support)  
79,000 Btu/Hr (actual amount of  
Btu/Hr used)  
1. Determine the volume of the space (length  
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.  
Your options are as follows:  
x width x height).  
Length x Width x Height =__________cu. ft.

Example: Space size 22 ft. (length) x 18 ft.  
(width) x 8 ft. (ceiling height) = 3168 cu. ft.  
(volume of space)  
A. Rework work sheet, 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 8.  
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. Multiply the space volume by 20 to determine  
the maximum Btu/Hr the space can sup-  
port.  
B. Vent room directly to the outdoors. See  
Ventilation Air from Outdoors, page 8.  
C. Install a lower Btu/Hr gas log heater, if  
lower Btu/Hr size makes room uncon-  
fined.

mum Btu/Hr the space can support)  
Example: 3168 cu. ft. (volume of space) x 20  
= 63,360 (maximum Btu/Hr the space can  
support)  
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.

Ventilation Air From Outdoors  
VENTILATION AIR  
Provide extra fresh air by using ventilation  
grills or ducts. You must provide two perma-  
nent openings: one within 12" of the ceiling  
and one within 12" of the floor. Connect these  
items directly to the outdoors or spaces open  
to the outdoors. These spaces include at-  
tics and crawl spaces. Follow the National  
Fuel Gas Code ANS Z223.1/NFPA 54 Air for  
Combustion and Ventilation for required size  
of ventilation grills or ducts.  
Ventilation Air From Inside Building  
This fresh air would come from an adjoining  
unconfined space. When ventilating to an  
adjoining unconfined 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 option  
1, Figure 3). You can also remove door into  
adjoining room (see option 2, Figure 3). Fol-  
low the National Fuel Gas Code ANS Z223.1/  
NFPA 54 Air for Combustion and Ventilation  
for required size of ventilation grills or ducts.  
IMPORTANT: Do not provide openings for  
inlet or outlet air into attic if attic has a thermo-  
stat-controlled power vent. Heated air entering  
the attic will activate the power vent.

Mantel Clearances for Built-In  
Installation  
BUILT-IN OR INTERNAL WALL  
FIREBOx INSTALLATION  
If placing custom mantel above built-in fire-  
box, you must meet the minimum allowable  
clearance between mantel shelf and top of  
firebox opening shown in Figure 7. These are  
the minimum allowable mantel clearances  
for a safe installation. Use larger clearances  
wherever possible to minimize the heating of  
objects and materials placed on the mantel.  
Built-in installation of this firebox involves  
installing firebox into a framed-in enclosure.  
This makes the front of firebox flush with wall.  
If installing a mantel above the firebox, you  
must follow the clearances shown in Figure  
7. Follow the instructions below to install the  
firebox in this manner.  
1. Frame in rough opening. The firebox  
framing should be constructed of 2 x 4  
lumber or heavier. Construct framing  
using dimensions shown in Figure 8 and  
9, page 11. It is recommended that the  
framing be constructed first and the unit  
be placed in position.After sliding the unit  
into place, the flanges may be nailed to  
the framing before applying the wallboard  
to the exterior framing.  
CAUTION: Do not allow the  
vent-freegaslogheatertotouch  
or extend beyond the firebox  
screen.  
If your installation does not meet the above  
minimum clearances in Figure 7, you must:  
• raise the mantel to an acceptable height,  
OR  
2. If the vent-free firebox is to be installed  
directly on carpeting, tile (other than ce-  
ramic) or any combustible material other  
than wood flooring; the vent-free firebox  
must be installed upon a metal or wood  
panel extending the full width and depth  
of the vent-free firebox.

Teflon tape or pipe joint compound (check with  
local codes as to the use of Teflon tape). Com-  
pounds used on threaded joints of gas piping  
shall be resistant to the action of propane/LP  
and should be applied lightly to ensure excess  
sealant does not enter the gas line.  
Model FBPS and FGPN can be hard-wired  
to the duplex outlet located inside the firebox  
bottom if desired. This allows the blower ac-  
cessory to be plugged into the duplex outlet.  
NOTICE: A qualified electrician  
mustconnectelectricalwiringto  
duplex outlet for built-in instal-  
lation. Follow all local codes. In  
absence of local codes follow  
TheNationalElectricCodeANS/  
NFPA 70.  
Complete your gas installation by connecting  
the incoming gas line to the appliance regula-  
tor. Secure all joints tightly with wrench but do  
not overtighten. If a flexible gas line is used,  
take care not to kink the connector.  
WARNING: All gas piping  
andconnectionsmustbetested  
for leaks after the installation is  
completed. After ensuring that  
the manual shutoff gas valve is  
open, apply a soap and water  
solution to all connections and  
joints. If bubbles appear, leaks  
can be detected and corrected.

A LEAK IS DETECTED.  
ELECTRICAL INSTALLATION  
A model GA3500A blower system assembly  
is available for use with the FBPS and FGPN  
(-LS) vent-free firebox as an optional acces-  
sory. This blower is designed to be installed  
on either side of the FBPS and FGPN(-LS)  
firebox, when provisions for a 120 VAC sup-  
ply connection are made at either end of the  
cabinet. Use of a blower system other than  
those manufactured by FMI PRODUCTS, LLC  
voids the warranty.  
Electrical connections are made within the  
receptacle with wires that are routed through  
the bushing provided (see Figure 15). The re-  
ceptacle may be relocated to either side, when  
necessary. However, the cover plate must be  
replaced over the unused access point. Be  
certain to properly ground the vent-free firebox  
using the green grounding wire.
