Read the following instructions 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. New materials, increased insulation, and new construction methods help reduce heat loss in homes.
AIR FOR COMBUSTION AND VENTILATION Continued DETERMINING AIR FLOW FOR FIREPLACE LOCATION Determining if You Have a Confined or Unconfined Space Use this work sheet to determine if you have a confined or unconfined space. Space: Includes the room in which you will install fireplace plus any adjoining rooms with doorless passageways or ventilation grills between the rooms. 1. Determine the volume of the space (length x width x height). Length x Width x Height = ___________________ cu. ft.
AIR FOR COMBUSTION AND VENTILATION Continued WARNING ICON G 001 WARNING If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3. VENTILATION AIR Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space.
INSTALLING NOTICE A qualified service person must install fireplace. Follow all local codes.

INSTALLING Continued ASSEMBLING AND ATTACHING OPTIONAL BRASS TRIM (Included with Mantel Accessory) IMPORTANT: If you are recessing the firebox in a wall, do not attach brass trim at this time. See page 13. Note: The instructions below show assembling and attaching brass trim to fireplace. 1. Remove packaging from three pieces of brass trim. 2. Locate four brass screws, two adjusting plates with set screws, and two shims in the hardware packet. 3. Align shim under adjusting plate as shown in Figure 6. 4.
INSTALLING INSTALLATION CLEARANCES Continued WARNING ICON G 001 WARNING Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling, and adjoining wall. Carefully follow the instructions below. This will ensure safe installation. Minimum Wall and Ceiling Clearances (see Figure 8) A. Clearances from the side of the fireplace opening to any combustible wall should not be less than 16 inches for a cabinet mantel or 12 inches for a corner installation. B.
INSTALLING Continued 3. Install gas piping to fireplace location. This installation includes an approved flexible gas line (if allowed by local codes) after the manual shutoff valve. The flexible gas line must be the last item installed on the gas piping. See Installing Gas Piping to Fireplace Location, page 15. 4. Place hearth base accessory against wall at installation location. Cut an access hole in hearth top to run flexible gas line to fireplace (see Figure 9).
INSTALLING Continued 9. Attach flexible gas line to fireplace gas regulator. See Connecting Fireplace to Gas Supply, page 17. 10.If blower is installed, route blower electrical cord through access holes in either side of fireplace. Note: Bushing may be moved if necessary. Plug electrical cord into electrical outlet. 11.Carefully insert fireplace into cabinet mantel. Be careful not to scratch or damage hearth base, cabinet mantel, or any laminate trim on hearth base.
