propane/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.

warnings. Keep this manual for reference. It

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. Dur-

ing 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 ap-

pliances 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, Air for

Combustion and Ventilation.

All spaces in homes fall into one of the three

following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space

The information on pages 5 through 7 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 un-

usually tight construction, you must provide

additional fresh air.

Example: Space size 20 ft. (length) x 16 ft.

(width) x 8 ft. (ceiling height) = 2,560 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. Multiply the space volume by 20 to determine

the maximum Btu/Hr the space can support.

________ (volume of space) x 20 = (Maxi-

mum Btu/Hr the space can support)

Example: 2,560 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 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.

Direct-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: 51,200 Btu/Hr (maximum the

space can support)

73,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the example is a conned 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

unconned space, remove door to adjoining

room or add ventilation grills between rooms.

See Ventilation Air From Inside Building.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors page 8.

C. Install a lower Btu/Hr replace, if lower Btu/Hr

size makes room unconned.

This fresh air would come from an adjoining

unconned space. When ventilating to an

adjoining unconned space, you must provide

two permanent 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 3). You can also remove door

into adjoining room (see option 3, Figure 3).

Note: Your replace is designed to be used

in zero clearance installations. Wall or fram-

ing 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.

Use the dimensions shown for rough openings

to create the easiest installation. See Built-In

Fireplace Installation, page 11.

IMPORTANT: Vent-free heaters 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 Ventila-

tion, page 6.

IMPORTANT: Make sure the fireplace is

level. If replace is not level, log set will not

work properly.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation

grills or ducts. You must provide two perma-

nent 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, 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 thermo-

stat-controlled power vent. Heated air entering

the attic will activate the power vent.

INSTALLATION

Continued

2. When installing blower, install a properly

grounded, 120 volt three-prong electrical

outlet at replace location if an outlet is not

there. If possible, locate outlet so cabinet

mantel will cover it when installed (see

Figure 9).

3. Install gas piping to replace location. This

installation includes an approved exible

gas line (if allowed by local codes) after

the equipment shutoff valve. The exible

gas line must be the last item installed on

the gas piping. See Installing Gas Piping

to Fireplace Location, page 13.

4. Place hearth base accessory against wall at

installation location. Cut an access hole in

hearth top to run exible gas line to replace

(see Figure 9). Make sure to locate access

hole so cabinet mantel will cover it when

installed.

Note: You can secure base to oor using

wood screws. Countersink screw heads

and putty over.

5. Route exible gas line through access

hole in hearth base.

6. Center cabinet mantel on hearth base (see

Figure 10, page 11). Make sure mantel is

ush against wall.

7. Break off nailing anges (see Figure 11,

page 11) with hammer or pliers.

8. Place cardboard or other protective mate-

rial on top of hearth base. Carefully set

replace on protective material, with back

of replace inside mantel opening.

9. Attach exible gas line from replace gas

regulator to gas supply. See Connecting

Fireplace to Gas Supply, page 14.
