LOCATING
FIREBOX
PLANNING
Plan where you will install the firebox. This
will save time and money later when you
install the firebox. Before installation, con-
sider the following:
1. Where the firebox will be located. Al-
low for wall and ceiling clearances (see
Installation Clearances, page 7).
2. Everything needed to complete instal-
lation.
3. These models CANNOT be installed
in a bedroom or bathroom.
4. Proper air for combustion and ventila-
tion (see below).
AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This firebox shall
not be installed ina confined space
or unusually tight construction
unless provisions are provided
foradequate combustion and ven-
tilation air. Reed the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Today's homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
help reduce heat loss inhomes. 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
efficient, your home needs to breathe. Fresh
air most enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaust fans, fireboxes, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following _re excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-
tion 5.3, 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
The information on pages 4 through 6 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and win-
dows 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
defined as construction where:
a. walls and ceilings exposed to
the outside atmosphere have
a continuous water vapor
retarder with a rating of one
perm (6x10"11kg per pa-sec-m=)
or less with openings
gasketed or sealed and
b. weather stripping has been
added on opeaable windows
and doors and
c. caulldng or sealants are applied
to areas such as joints around
window and door frames, be-
tween sole plates and floors, be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tionsfor 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 6.
If your home does not meet all of the
three criteria above, proceed to
Determining Fresh-Air Flow For
Fireplace Location, page 5.
Confined and Unconfined Space
The National Fuel Gas Code (ANS Z2123.1,
1992 Section 5.3) defines a confined 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
unconfined space asa 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
unconfined space.
This firebox shall not be installed in a con-
fined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
*Adjoining rooms are communicating only
ifthere are doorless passageways or ventila-
tion grills between them.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install firebox 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. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.
(volume of space) + 50 cu. ft. = (Maximum Btu/Hr the space can support)
Example: 3168 cu. ft. (volume of space) .'-50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free firebox Btu/Hr
Gas water heater* Btu/Hr Example:
Gas furnace Btu/Hr Gas water heater 40,000 Btu/Hr
Vented gas heater Btu/Hr Vent-free firebox with log heater + 39,000 Btu/Hr
Gas firebox logs Btu/Hr Total 79,000 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.
4. Compare the tnaximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
Btu/l-lr (maximum the space can support)
Btu/Hr (actual amount of Btu/Hr used)
Example: 63,300 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 confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.
Yon 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 unconfined space, remove door to adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.
C. Install a lower Btu/Hr fireplace, if lower Btu/I-Ir size makes room unconfined.
"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.
I
_lb WARNING: Ifthe area In which the firebox end gas log heater may be operated is smeller than that defined as I
an unconfined space or If the building Is of unusually tight construction, provide adequate combustion and I
ventilation air by one of the methods described in the National Fuel Gas Code, ANS Z223.1, 1992, Section 5.3 or
eppllceble local codes.

Ventilation Air From Inside
Building
This fresh air would come from an adjoining
unconfined space. When ventilating to an
adjoining unconfined space, you must pro-
vide two permanent openings: one within
12" of the ceiling and one within 12" of the
floor on the wall connecting the two spaces
(see options 1and 2, Figure 4). You can also
remove door into adjoining room (see op-
tion 3, Figure 4), Follow the National Fuel
Gas Code NFPA 54/ANS Z223.1, Section
5.3, Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
WARNING: Rework work-
sheet, adding the space of the
adjoining unconfined space. The
combined spaces must have
enough fresh air to supply all
appliances In both spaces.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two per-
manent 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 attics and crawl spaces.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.
