PLANNING
Plan where you will install the rebox. This will
save time and money later when you install
the rebox. Before installation, consider the
following:
1. Where the rebox 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 condition ducts, windows or doors.
6. A location that minimizes modications
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-
LOCATING FIREBOX
erwise common areas when added to an
existing, nished wall (see Figure 2).
Internal wall installation provides a
discreet viewing option between two
adjacent rooms or within an added wall
to subdivide an oversize room.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
not be installed in a room or
space unless the required volume of indoor combustion air
is provided by the method described in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, the
International Fuel Gas Code, or
applicable local codes. Read the
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
Today’s homes are built more energy efcient
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.
While it is good to make your home energy
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning appliances need fresh air for proper combustion
and ventilation.
Exhaust fans, reboxes, clothes dryers and fuel
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.
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 classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 6 through 8 will help
you classify your space and provide adequate
ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of unusually tight construction, you must provide
additional fresh air.
Unusually tight construction is dened 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
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 oors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical and gas lines
and at other openings.
If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 8.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Firebox Location,
page 7.
Conned and Unconned Space
The National Fuel Gas Code ANS Z223.1/
NFPA 54 denes a conned 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 unconned 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 unconned space.
This heater shall not be installed in a conned
space or unusually tight construction unless
provisions are provided for adequate combustion and ventilation air.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.

DETERMINING FRESH-AIR FLOW
FOR FIREBOX LOCATION
Determining if You Have a Conned or
Unconned Space
Use this work sheet to determine if you have
a conned or unconned space.
Space: Includes the room in which you will
install heater plus any 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: Space size 22 ft. (length) x 18 ft.
(width) x 8 ft. (ceiling height) = 3168 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. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
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)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Gas water heater* __________ Btu/Hr
Gas furnace __________ Btu/Hr
Vented gas heater __________ Btu/Hr
Gas replace logs __________ Btu/Hr
Other gas appliances* + _________ Btu/Hr
Total = _________ Btu/Hr
* Do not include direct-vent gas appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
Example:
Gas water heater __________ Btu/Hr
Gas rebox logs + _________ Btu/Hr
Total = _________ Btu/Hr
40,000
39,000
79,000
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: 63,360 Btu/Hr (max imum t he
space can support)
79,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above example is a conned
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:
A. Rework work sheet, adding the space
of an adjoining room. If the extra space
provides an unconned space, remove
door to adjoining room or add ventilation
grills between rooms. See Ventilation Air
from Inside Building, page 8.
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 unconned.
If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the
space is an unconned space. You will need
no additional fresh air ventilation.
WARNING: If the area in which
the heater may be operated does
not meet the required volume for
indoor combustion air, combustion and ventilation air shall be
provided by one of the methods
described in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54,
the International Fuel Gas Code,
or applicable local codes.

Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor 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.
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 oor. 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.
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.

CAUTION: Log heaters in-
stalled in this rebox create warm
air currents. These currents move
heat to wall surfaces next to rebox. Installing rebox next to vinyl
or cloth wall coverings or operating rebox where impurities (such
as, but not limited to, tobacco
smoke, aromatic candles, cleaning uids, oil or kerosene lamps,
etc.) in the air exist, may discolor
walls or cause odors.
IMPORTANT: Vent-free gas log heaters add
moisture to the air. Although this is benecial,
installing rebox in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See Air for Combustion
and Ventilation, page 6.
IMPORTANT: Make sure the rebox is level.
If rebox is not level, log set will not work
properly.
Note: Your Vanguard rebox is designed to
be used in zero clearance installations. Wall
or framing material can be placed against any
exterior surface on the rear, sides or top of
your rebox, except where standoff spacers
are integrally attached. If standoff spacers
are attached to your rebox, these spacers
can be placed directly against wall or fram-
ing materials.
Use dimensions shown for rough openings to
create the easiest installation (see Built-In or
Internal Wall Firebox Installation, page 9).

Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in rebox, you must meet the minimum allowable
clearance between mantel shelf and top of
rebox 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.
CAUTION: Do not allow the
vent-free gas log heater to touch
or extend beyond the rebox
screen.
If your installation does not meet the above
minimum clearances in Figure 7, you must:
• raise the mantel to an acceptable height,
OR
• remove the mantel.
BUILT-IN OR INTERNAL WALL
FIREBOX INSTALLATION

INSTALLATION
Continued
Prepare incoming black iron gas line with
Teon tape or pipe joint compound (check with
local codes as to the use of Teon tape). Compounds 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.
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 exible gas line is used,
take care not to kink the connector.
WARNING: All gas piping
and connections must be tested
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.
DO NOT USE OPEN FLAME FOR
LEAK TESTING AND DO NOT
OPERATE ANY APPLIANCE IF
A LEAK IS DETECTED.
GAS SUPPLY TESTING
Note: This section is intended as a guide for
qualied technicians installing gas to this
vent-free rebox.
CAUTION: Do not connect
vent-free heater before pressure
testing gas piping. Damage to
gas valve may result and an un-
safe condition may be caused.
The appliance and its’ individual shutoff valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at test pressures in excess of 1/2
psig (3.5 kPa).
The appliance must be isolated from the gas
supply piping system by closing manual 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).
HARD-WIRING FIREBOX
Model FBPS and FGPN can be hard-wired
to the duplex outlet located inside the rebox
bottom if desired. This allows the blower ac-
cessory to be plugged into the duplex outlet.
NOTICE: A qualied electrician
must connect electrical wiring to
duplex outlet for built-in installation. Follow all local codes. In
absence of local codes follow
The National Electric Code ANS/
NFPA 70.
ELECTRICAL INSTALLATION
A model GA3500A blower system assembly
is available for use with the FBPS and FGPN
(-LS) vent-free rebox as an optional accessory. This blower is designed to be installed
on either side of the FBPS and FGPN(-LS)
rebox, when provisions for a 120 VAC supply 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 rebox
using the green grounding wire.

OPERATING GUIDELINES AND MAINTENANCE
INSTRUCTIONS
When lit for the rst time, a vent-free log
heater will emit a slight odor for about an hour
or two. This is a normal occurrence which is
due to the “curing” of the logs and the “burn-in”
of internal paints and lubricants used in the
manufacturing process.
Keep control compartments, logs, burners
and areas surrounding the logs clean by
vacuuming or brushing at least twice a year.
Temporary removal of the log set may ease
the cleaning of the burner and pilot assembly.
In cleaning, take care not to alter the settings
on the pilot assembly. See the operating
instructions supplied with your vent-free log
heater for additional cleaning instructions.
WARNING: Logs can be very
hot! Allow logs to cool before
handling.
IMPORTANT: Turn off the gas supply at the
external shutoff valve before servicing appliance. Any safety screen or guard removed for
servicing must be replaced prior to operating
the appliance.
www.fmiproducts.com
Installation and repair should be done by a
qualied person. The appliance 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, pet hair, etc. It is imperative
that the control compartments, burners and
circulating air passageways of the appliance
be kept clean.
WARNING: Children and
adults should be alerted to the
hazards of high surface temperatures and to stay away to avoid
burns or clothing ignition. Young
children should be carefully
supervised when they are in the
same room as the appliance.
For lighting and operating t his vent-free
rebox, please refer to the vent-free gas logs
manufacturer’s instruction manual.
