monoxide poisoning resemble the u, with head-
aches, dizziness, or nausea. If you have these signs,
the replace may not be working properly. Get
fresh air at once! Have replace serviced. Some
people are more affected by carbon monoxide than
others. These include pregnant women, people with
heart or lung disease or anemia, those under the
inuence of alcohol, and those at high altitudes.

pane/LP gases are odorless. An odor-making agent
is added to the gas. The odor helps you detect a gas
leak. However, the odor added to the gas can fade.
Gas may be present even though no odor exists.
Make certain you read and understand all warnings.
Keep this manual for reference. It is your guide to
safe and proper operation of this replace.

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 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.

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 fol-
lowing 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.

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.

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. Di-
rect-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: 35,840 Btu/Hr (maximum the space
can support)
40,000 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 maxi-
mum 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 adjoin-
ing 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 Ventila-
tion Air From Outdoors, page 8.
C. Install a lower Btu/Hr replace, 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.

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 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 per hour
(4.8 m3 per kw) of the aggregate input rating of
all appliances installed in that space. Rooms com-
municating directly with the space in which the
appliances are installed*, through openings not
furnished with doors, are considered a part of the
unconned space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation grills
between them.

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.

This fresh air would come from an adjoining un-
conned space. When ventilating to an adjoining
unconned space, you must provide two perma-
nent 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 5). Follow the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, Section 5.3, 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 permanent 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,
Section 5.3, 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 thermostat-
controlled power vent. Heated air entering the attic
will activate the power vent.

IMPORTANT: Vent-free replaces add moisture to
the air. Although this is benecial, installing replace
in rooms without enough ventilation air may cause
mildew to form from too much moisture. See Air for
Combustion and Ventilation, page 6.
Note: Your replace is designed to be used in zero
clearance installations. Wall or framing material can be
placed directly against any exterior surface on the rear,
sides, or top of your replace, except where standoff
spacers are integrally attached. If standoff spacers are
attached to your replace, these spacers can be placed
directly against wall or framing materials.
Note: When installing replace directly on carpet-
ing, tile or other combustible material, other than
wood ooring, the replace shall be installed on a
metal or wood panel extending the full width and
depth of the replace.
Use the dimensions shown for rough openings to
create the easiest installation (see Built-In Fire-
place Installation, page 10).

Use the correct gas type (natural or propane/LP)
for your unit. If your gas supply is not correct, do
not install replace. Call dealer where you bought
replace for proper type replace.

This makes the front of replace ush with wall.
An optional brass trim kit accessory is available
(see Accessories, page 38). Brass trim will extend
past sides of replace approximately 1/2". This
will cover the rough edges of the wall opening.
If installing a built-in mantel above the replace,
you must follow the clearances shown in Figure 11,
page 12. Follow the instructions below to install
the replace in this manner.
Actual Framing
Height 26" 26 7/8"
Front Width 26 3/4" 26 7/8"
Depth 14 1/4" 15 1/4"
1. Frame in rough opening. Use dimensions
shown in Figure 7 for the rough opening. If
installing in a corner, use dimensions shown in
Figure 8 for the rough opening. The height is
26 7/8" which is the same as the wall opening
above.
2. If installing GA3450TA blower accessory, do
so at this time. Follow instructions included
with blower accessory.
Note: If not installing blower accessory, you
may wish to run electrical wiring to your
replace for future blower installation (see
