AIR FOR COMBUSTION AND VENTILATION
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
-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.
Conned and Unconned Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA 54 denes a conned 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 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 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 unconned space.
* 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.
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 fuelburning 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 ne eds to breathe. Fresh
air must enter your home. All fuel-burning appliances need fresh air for proper combustion
and ventilation.
Exhaust fans, replaces, 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, ANSI 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 8 through 10 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.

126770-01A 9
AIR FOR COMBUSTION AND VENTILATION
Continued
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) = 3,168 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: 3,168 cu. ft. (volume of space) x 20 =
63,360 (maximum Btu/Hr space can support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Vent-free replace _________ 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 appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
Example:
Gas water heater _________ Btu/Hr
Vent-free replace _________ Btu/Hr
Total = _________ Btu/Hr
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 example is a conned 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
unconned space, remove door to adjoining
room or add ventilation grills between rooms.
See Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 10.
C. Install a lower Btu/Hr replace, 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
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 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.

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.
WARNING: A qualied ser-
vice person must install rebox.
Follow all local codes.
WARNING: Never install
rebox
• in a bedroom or bathroom*
• in a recreational vehicle
• where curtains, furniture,
clothing, or other ammable
objects are less than 36" from

4, page 11
• in high trafc areas
• in windy or drafty areas
* Unless installed log set is rated at 10,000
Btu/Hr or less, 6,000 for bathrooms
CAUTION: Log heaters
installed 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.
INSTALLATION
NOTICE: The rebox identication label (including model number, serial number, clearances,
etc.) is located on a chain under
the bottom refractory.
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, page 8.
IMPORTANT: Make sure the rebox is level.
If rebox is not level, log set will not work
properly.
Note: Your 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, top or bottom 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 framing materials. Use the dimensions shown for rough
opening to create the easiest installation.

1. Moisten brick surface with damp sponge
or spray bottle just prior to application.
When bricks are wet, any excess grout
mixture on bricks will easily wipe off.
2. In a heavy duty mixing bucket, add equal
parts cement and sand. Add enough water
and mix together well using a power drill
with mixing wand attachment to a yogurt
like consistency. Not adding enough water
can lead to grout falling out after burning.
3. The overall length of piping bag should be
about 16". If the bag is longer than 16",
cut it down to size by removing end with
larger opening. This will make the bag
easier to handle.
4. Put grout mixture into piping bag making
sure the smaller opening is downward and
over a moist towel to avoid spilling. Place
a wet towel over the bucket making sure it
is directly on the surface of grout mixture.
This will keep the mixture moist and it will
not dry out before use.
5. Grout all joints where two rebrick walls
come together.
6. Using a trowel, remove excess grout mixture by moving trowel in the direction of
the joint. Grout mixture in the joint should
now be ush with brick surface. If not
enough grout is applied into each space,
grout may fall out after burning.
7. Using a joint striker, smooth out grout line.
Allow 72 hours before
operating replace.
