PRODUCT FEATURES
OPERATION
This rebox is designed for use with approved
ANSI Z21.11.2 decorative type unvented room
heaters. (Physical size limitations apply. Refer
to minimum rebox requirements supplied
with log heater.) It requires no outside vent-
ing or chimney making installation easy and
inexpensive. When used without the blower,
the rebox requires no electricity making it
ideal for emergency backup heat.
BLOWER ACCESSORY
The circulating models will accept either a ro-
tary type fan (model BK) or the triple radial fan
blower system (model BK3) accessories. The
blower circulates heated air from the rebox
into the room. Use of blower is optional.
REFRACTORY BRICK LINER
Your rebox may feature a concrete refrac-
tory brick liner. As with all concrete liners,
this liner may develop slight cracks when
exposed to heat. These cracks will not affect
the performance of the replace or vent-free
gas logs.
OPTIONAL FIBER AND PORCELAIN
LINERS
For a vintage look, the ber panels give a
old masonry brick look and are light weight
and easy to install. For a modern look, the
porcelain panels accessory have a black
sleek nish that reects the glow of the ame.
OPTIONAL OUTSIDE AIR KIT
The optional AK4 and AK4F air kit provides
additional outdoor air to improve burner ef-
ciency and reduce build-up of condensation
in the living space. Follow the instructions
included with the air kit.
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 11).
2. Everything needed to complete installation.
3. These models CANNOT be installed in a
bedroom unless the maximum BTU rating
of the installed vent-free log set is less
than 10,000 Btu/Hr.
4. Proper air for combustion and ventilation
(page 8).

AIR FOR COMBUSTION AND 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 10.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Firebox Location,
page 9.
Conned and Unconned Space
The National Fuel Gas Code, ANSI 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 per hour (4.8 m3 per kw) of the ag-
gregate 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 per hour (4.8 m3 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 un-
conned space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
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 appli-
ances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National Fuel
Gas Code, ANSI 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 page 8 through 10 will help
you classify your space and provide adequate
ventilation.

DETERMINING FRESH-AIR FLOW
FOR HEATER 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 deter-
mine 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 appli-
ances in the space.
Vent-free heater _______ Btu/Hr
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 appli-
ances. Direct-vent draws combustion
air from the outdoors and vents to the
outdoors.
Example:
Gas water heater _________ Btu/Hr
Vent-free heater +________ Btu/Hr
Total =________ Btu/Hr
AIR FOR COMBUSTION AND VENTILATION
Continued
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 worksheet, 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 10.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 10.
C. Install a lower Btu/Hr 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: If the 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 options
1 and 2, Figure 4). You can also remove door
into adjoining room (see option 3, Figure 4).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
AIR FOR COMBUSTION AND VENTILATION
Figure 5 - Ventilation Air from Outdoors
Figure 4 - Ventilation Air from Inside
Building
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 attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI 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.
