PRODUCT FEATURES
OPERATION
This rebox is designed for use with approved
ANS Z21.11.2 decorative type unvented room
heaters. (Physical size limitations apply. Refer
to minimum rebox requirements supplied
with log heater.) The maximum size log this
rebox will accept is: width of 32", depth of
19" and a height of 17".
This rebox requires no outside venting or
chimney making installation easy and inex-
pensive. When used without the blower, the
rebox requires no electricity making it ideal
for emergency backup heat.
BLOWER ACCESSORY
The FBPS, FGPN and FGPN-LS rebox will
accept the GA3500A accessory. The variable
blower allows you to select the fan speed
you desire. The blower circulates heated air
from the rebox into the room. Use of blower
is optional.
BRICK LINER

LOCATING FIREBOX
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 condi-
tion ducts, windows or doors.
6. A location that minimizes modications
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-
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.

www.fmiproducts.com 105163-01E6
AIR FOR COMBUSTION AND VENTILATION
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/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 efcient
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
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances 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 classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned 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 un-
usually tight construction, you must provide
additional fresh air.
Unusually tight construction is dened 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 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.
Conned and Unconned Space
The National Fuel Gas Code ANS Z223.1/
NFPA 54 denes a conned 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 unconned 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-
conned space.
This heater shall not be installed in a conned
space or unusually tight construction unless
provisions are provided for adequate combus-
tion 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 Conned or
Unconned Space
Use this work sheet to determine if you have
a conned or unconned 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 sup-
port.
________ (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
AIR FOR COMBUSTION AND VENTILATION
Continued
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 (maximum the
space can support)
79,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above example is a conned
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 unconned 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 uncon-
ned.
If the actual Btu/Hr used is less than the
maximum Btu/Hr the space can support, the
space is an unconned space. You will need
no additional fresh air ventilation.
WARNING:Ifthe area in which
the heater may be operated does
not meet the required volume for
indoor combustion air, combus-
tion 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
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned 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 perma-
nent 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.
NOTICE: This rebox in com-
bination with unvented log
sets are intended for use as
supplemental heat. Use along
with your primary heating
system. Do not install them as
your primary heat source. If you
have a central heating system,
you may run system’s circulat-
ing blower while using heater.
This will help circulate the heat
throughout the house. In the
event of a power outage, you
can use unvented logs as your
primary heat source.
WARNING: A qualied ser-
vice person must install rebox.
Follow all local codes.
WARNING: Never install the
rebox
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture,
clothing or other ammable
objects are less than 42" from
the front, top or sides of the
rebox
• in high trafc areas
• in windy or drafty areas

www.fmiproducts.com
105163-01E 9
CAUTION: Log heaters in-
stalled in this rebox create warm
air currents. These currents move
heat to wall surfaces next to re-
box. Installing rebox next to vinyl
or cloth wall coverings or operat-
ing rebox where impurities (such
as, but not limited to, tobacco
smoke, aromatic candles, clean-
ing 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 benecial,
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).
INSTALLATION CLEARANCES
WARNING: Maintain the
minimum clearances. If you can,
provide greater clearances from
oor, ceiling and adjoining wall.

BUILT-IN OR INTERNAL WALL
FIREBOX INSTALLATION
Built-in installation of this rebox involves
installing rebox into a framed-in enclosure.
This makes the front of rebox ush with wall.
If installing a mantel above the rebox, you
must follow the clearances shown in Figure
7. Follow the instructions below to install the
rebox 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 rst and the unit
be placed in position. After sliding the unit
into place, the anges may be nailed to
the framing before applying the wallboard
to the exterior framing.
2. If the vent-free rebox is to be installed
directly on carpeting, tile (other than ce-
ramic) or any combustible material other
than wood ooring; the vent-free rebox
must be installed upon a metal or wood
panel extending the full width and depth
of the vent-free rebox.
