FIREPLACE INSTALLATION
NOTICE: This fireplace is in- tended for use as supplemental heat. Use this fireplace along with your primary heating system. Do not install this fireplace as your primary heat source. If you have a central heating system, you may run system's circulating blower while using fireplace. This will help circulate the heat through- out the house. In the event of a power outage, you can use this fireplace as a heat source.
WARNING: A qualified ser- vice person must install fireplace. Follow all local codes.
CAUTION: This fireplace cre- ates warm air currents. These cur- rents move heat to wall surfaces next to fireplace. Installing fire- place next to vinyl or cloth wall coverings or operating fireplace where impurities (such as to- bacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may discolor walls.
Note: Your fireplace 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 fireplace, except where standoff spacers are integrally attached. If standoff spacers are attached to your fireplace, these spacers can be placed directly against wall or framing material. See framing details on page 4.
