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.

Gas water heater* ___________ Btu/Hr

Gas furnace ___________ Btu/Hr

Vented gas heater ___________ Btu/Hr

Gas replace logs ___________ Btu/Hr

Other gas appliances* + __________ Btu/Hr

* Do not include direct-vent gas appliances. Di-

rect-vent draws combustion air from the outdoors

and vents to the outdoors.

Example:

_______

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.

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).

INSTALLATION

Built-in installation of this fireplace involves

installing replace into a framed-in enclosure.

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.

Extension Cord

Use extension cord if needed. The cord must

have a three-prong, grounding plug and a three-

hole receptacle. Make sure cord is in good shape.

It must be heavy enough to carry the current

needed. An undersized cord will cause a drop in

line voltage. This will result in loss of power and

overheating. Use a No. 16 AWG cord for lengths

less than 50 feet.

Installation must include an equipment shutoff

valve, union, and plugged 1/8" NPT tap. Locate

NPT tap within reach for test gauge hook up. NPT

tap must be upstream from heater (see Figure 22).

IMPORTANT: Install equipment shutoff valve

in an accessible location. The equipment shutoff

valve is for turning on or shutting off the gas to

the appliance.

Check your building codes for any special re-

quirements for locating equipment shutoff valve

to replaces.

Apply pipe joint sealant lightly to male NPT

threads. This will prevent excess sealant from

going into pipe. Excess sealant in pipe could result

in clogged replace valves.

incoming gas pressure. You must reduce incoming gas

pressure to between 11" and 14" of water. If you do

not reduce incoming gas pressure, replace regulator

We recommend that you install a sediment trap in

supply line as shown in Figure 22, page 16. Locate

sediment trap where it is within reach for cleaning.

Install in piping system between fuel supply and

heater. Locate sediment trap where trapped mat-

ter is not likely to freeze. A sediment trap traps

moisture and contaminants. This keeps them from

going into replace controls. If sediment trap is

not installed or is installed wrong, replace may

not run properly.

The primary air inlet holes allow the proper amount

of air to mix with the gas. This provides a clean

burning ame. Keep these holes clear of dust, dirt,

lint, and pet hair. Clean these air inlet holes prior to

each heating season. Blocked air holes will create

soot. We recommend that you clean the unit every

three months during operation and have replace

inspected yearly by a qualied service person.

We also recommend that you keep the burner

tube and pilot assembly clean and free of dust and

dirt. To clean these parts we recommend using

compressed air no greater than 30 PSI. Your local

computer store, hardware store, or home center

may carry compressed air in a can. You can use a

vacuum cleaner in the blow position. If using com-

pressed air in a can, please follow the directions on

the can. If you don’t follow directions on the can,

you could damage the pilot assembly.

1. Shut off the unit, including the pilot. Allow

the unit to cool for at least thirty minutes.

2. Inspect burner, pilot, and primary air inlet

holes on injector holder for dust and dirt (see

Figure 49).

3. Blow air through the ports/slots and holes in

the burner.

4. Check the injector holder located at the end

of the burner tube again. Remove any large

particles of dust, dirt, lint, or pet hair with a

soft cloth or vacuum cleaner nozzle.

5. Blow air into the primary air holes on the

injector holder.

6.

In case any large clumps of dust have now been

pushed into the burner repeat steps 3 and 4.

Clean the pilot assembly also. A yellow tip on the

pilot ame indicates dust and dirt in the pilot as-

sembly. There is a small pilot air inlet hole about

2" from where the pilot ame comes out of the

pilot assembly (see Figures 50 or 51 depending on

model). With the unit off, lightly blow air through

the air inlet hole. You may blow through a drinking

straw if compressed air is not available.
