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

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.

Length x Width x Height =__________cu. ft.

(volume of space)

Example: Space size 16 ft. (length) x 14 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-

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.

INSTALLATION ITEMS

Before installing replace, make sure you have

the items listed below.

• external regulator (supplied by installer, for

propane/LP units only)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection*

• ground joint union

• sediment trap

• tee joint

• pipe wrench

* A CSA design-certied equipment shutoff valve

with 1/8" NPT tap is an acceptable alternative to

test gauge connection. Purchase the optional CSA

design-certied equipment shutoff valve from your

dealer. See Accessories, page 38.

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

Accessories, page 38). Use only approved

three-wire electrical wiring.
