LOCATING FIREBOX
AIR FOR COMBUSTION AND VENTILATION
Providing Adequate Ventilation
LOCATING FIREBOX
Plan where you will install the firebox. This will save time and
money later when you install the firebox. Before installation,
consider the following:
1. Where the firebox will be located. Allow for wall and ceiling
clearances (see Installation Clearances, page 6).
2. Everything needed to complete installation.
3. Thesemodels CANNOT beinstalled in abedroomor bathroom.
4. Proper air for combustion and ventilation (see below).
Today’s homes are built more energy efficient than ever. New materi-
als, increased insulation, and new construction methods help reduce
heat loss in homes. Home owners weather strip and caulk around
windowsanddoorstokeepthecoldairoutandthe warm air in. During
heatingmonths,home owners wanttheirhomesas airtight aspossible.
While it is good to make your home energy efficient, your home
needs to breathe. Fresh air must enter your home. All fuel-burning
appliances need fresh air for proper combustion and ventilation.
Exhaustfans,fireboxes,clothesdryers,andfuelburningappliances
drawairfromthehousetooperate.Youmustprovideadequatefresh
air for these appliances. This will insure proper venting of vented
fuel-burning appliances.
AIR FOR COMBUSTION AND
VENTILATION
WARNING: This firebox shall not be installed in a
confined space or unusually tight construction un-
less provisions are provided for adequate combus-
tion and ventilation air. Read the following instruc-
tionstoinsureproperfreshairforthisandotherfuel-
burning appliances in your home.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code ANSI
Z223.1/NFPA 54, Section 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 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 defined as construction
where:
a. walls and ceilings exposedto the outside atmosphere
have a continuous water vapor retarder with a rating
of one perm (6x10-11 kg per pa-sec-m2) or less with
openings gasketed or sealed and
b. weather stripping has been added on openable win-
dows and doors and
c. caulking or sealants are applied to areas such as
joints around window and door frames, between sole
platesandfloors,betweenwall-ceilingjoints,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 6.
If your home does not meet all of the three criteria above,
proceed to Determining Fresh-Air Flow For Firebox Loca-
tion , page 5.
Confined Space and Unconfined Space
The National Fuel Gas Code ANSI Z223.1/NFPA 54 defines a
confined space as a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m3per kw) of the aggregate input rating
of all appliances installed in that space and an unconfined space as
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper
hour (4.8 m3per 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
furnishedwithdoors,areconsideredapartof the unconfined space.
* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.
PRODUCT FEATURES
OPERATION
This firebox is designed to accept unvented decorative gas logs. It
requiresnooutsideventingorchimneymakinginstallationeasyand
inexpensive. When used without the blower the firebox requires no
electricity making it ideal for emergency backup heat.
BLOWER ACCESSORY
The CGFB32CA firebox will accept the GA3750 accessory. The
variable blower allows you to select the fan speed you desire. The
blower circulates heated air from the firebox into the room. Use of
blower is optional.

DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space
Usethis worksheetto determineif youhavea confinedor unconfinedspace.
Space:Includestheroominwhichyouwillinstallheaterplusanyadjoining
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 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling
height) = 2560 cu. ft. (volume of space)
Ifadditional ventilationtoadjoiningroomis suppliedwith grillsoropen-
ings, 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 = (Maximum Btu/Hr the space
can support)
Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum
Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater _____________ Btu/Hr
Gas water heater* _____________ Btu/Hr
Gas furnace _____________ Btu/Hr
Vented gas heater _____________ Btu/Hr
Gas fireplace logs _____________ Btu/Hr
Other gas appliances* + _____________ Btu/Hr
Total = _____________ Btu/Hr
* Do not include direct-vent gas appliances. Direct-vent draws com-
bustion air from the outdoors and vents to the outdoors.
Example:
Gas water heater _____________ Btu/Hr
Vent-free heater + _____________ 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: 51,200 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. 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 unconfined space, remove door to adjoining
roomor addventilation grillsbetweenrooms. SeeVentila tion AirF rom
InsideBuilding below.
B. Vent room directly to the outdoors. See Ventila tion Air F rom Out-
doors, page 6.
C. InstallalowerBtu/Hrheater,if lower Btu/Hr 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.

This fresh air would come from an adjoining unconfined space.
When ventilating to an adjoining unconfined space, you must
provide 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 1 and 2, Figure 4). You can also remove door into
adjoining room (see option 3, Figure 4). Follow the National Fuel
