PRODUCT FEATURES

SAFETY PILOT

This fireplace has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/pilot is a required feature for vent-tree room fireplaces. The ODS/pilot shuts off the fireplace if there is not enough fresh air.

PIEZO IGNITION SYSTEM

This fireplace has a piezo ignitor. This system requires no matches,

batteries, or other sources to light fireplace.

THERMOSTATIC HEAT CONTROL FOR THERMOSTAT-CONTROLLED MODELS

Thermostat-Controlled models have a thermostat sensing bulb and a control valve. The thermostat will automatically modulate the heat output to maintain a consistent room temperature. This results in greater fireplace comfort. This can also result in lower gas hills.

UNPACKING

AIR FOR COMBUSTION AND VENTILATION

Providing Adequate Ventilation

Determining Fresh-Air Flow for Fireplace Location

AIR FOR COMBUSTION AND VENTILATION

WARNING: This fireplace shall not be installed in

a confined space or unusually tight construction

unless provisions are provided for adequate com- bustion and ventilation air. Read the following in- structions to insure proper fresh air for this and other fuel-burning appliances in your home.

Today's homes are built more energy efficient than ever. Nev mate-

rials,

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 antight

as possible.

While it is good to make your home energy efficient

your

home needs to breathe. Fresh air must enter your borne. All fuel-burning appliances need fresh air for proper combustion and ventilation.

Exhaust fans, fireplaces, 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.

PROVIDING ADEQUATE VENTILATION

The following

are excerpts from

National Fuel Gas Code, ANSI

21223. I/NEPA 54. Section 5.3, Air for Combustion and Ventilation.

All

spaces in homes fall

iron

one of he throe

following ventilation

classifications:

Unusually Tight Construction

Unconfined Space

Confined Space

The information on pages 6 through S

ill help you classify your

space and provide adequate ventilation.

Unusually Tight Construction

c. caulking or sealants are applied to areas such as

joints around window and door frames, between sole

plates and floors, between wall-ceiling joints, between

wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.

If your home meets all of these three criteria, you must provide additional fresh air. See

Ventilation Air

From Outdoors,

page

If your home does not meet all of the three criteria above, proceed to

Determining Fresh-Air Flow For Fireplace

Location,

below.

Confined and Unconfined Space

The National Fuel Gus Code. ANSI Z223.1/NEPA 54

defines a

confined space as

a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 in' per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 in per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconfined space.

Adjoining rooms

are communicating only

if there are doorless

passaged\ ays or ventilation grills between them.

FIREPLACE CLEARANCES

WARNING: Maintain the minimum clearances shown in Figure 7. If you can, provide greater clear- ances from floor, ceiling, and joining wall.

NOTICE: If you install the fireplace in a bedroom (Thermostat-Controlled Models only), some building codes require that the fireplace/mantel system be

secured to (or within) a wall. You can position fire-

place in an optional cabinet or corner mantel. You can also recess fireplace into the wall.

If your fireplace is to be used with an optional mantel, the installation instructions included with your mantel shows an ESA approved method of attaching the l'ireplace/mantel system to a wall.

IMPORTANT:

Only use optional cabinet or corner mantels

specified in this manual. Purchase the optional mantel from your

dealer (see

any electrical source at this time.

Install fireplace electrical outlet and connect wiring to outlet before connecting to electrical source. The fireplace electrical outlet is included with the GA3450T

blower accessory. Only use the fireplace electrical outlet supplied with

the GA34507 blower accessory.

Note:

A qualified installer should make all electrical connections.

Install gas piping to fireplace location. This installation includes all approved flexible gas line (if allowed by local codes) after the equipment shutoff valve. The flexible gas line must be the last itern installed on the gas piping.

If you have not assembled firebox, follow instmetions on page 5.
