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 combustion and ventilation air. 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 FRESH-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 IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostatcontrolled power vent. Heated air entering the attic will activate the power vent.
INSTALLATION Fireplace Clearances Continued IMPORTANT: Vent-free fireplaces add moisture to the air. Although this is beneficial, installing fireplace in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, page 7. Note: Your fireplace is designed to be used in zero clearance installations.
INSTALLATION Continued Minimum Clearances For Side Combustible Material, Side Wall and Ceiling A. Clearances from the side of the fireplace cabinet to any combustible material and wall should follow diagram in Figure 6. Example: The face of a mantel, bookshelf, etc. is made of combustible material and protrudes 3 1/2" from the wall. This combustible material must be 4" from the side of the fireplace opening (see Figure 6). B.
INSTALLATION Continued 3. Install gas piping to fireplace location. This installation includes an approved flexible gas line (if allowed by local codes) after the equipment shutoff valve. The flexible gas line must be the last item installed on the gas piping. 4. If you have not assembled firebox, follow instructions on page 6. 5. Carefully set fireplace in front of rough opening with back of fireplace inside wall opening. 6. Attach flexible gas line to fireplace gas regulator.
