monoxide poisoning resemble the u, with head-

aches, dizziness or nausea. If you have these signs,

the heater 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 efficient

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.

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)

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: 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 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 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)

56,000 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.

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 4). 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.

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 re-

place in rooms without enough ventilation air may

cause mildew to form from too much moisture. See

Air for Combustion and Ventilation, page 6.

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.

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 27). 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 12,

page 12. Follow the instructions below to install

the replace in this manner. 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.
