INSTALLATION
Continued
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 materials.
Use the dimensions shown for rough openings
to create the easiest installation (see Built-In
Fireplace Installation, pages 9 and 10).
IMPORTANT:
Vent-free heaters add mois-
ture 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 Com-
bustion and Ventilation, pages 4 through 6.
IMPORTANT:
Make sure the fireplace is
level. If fireplace is not level, log set will not
work properly.
CHECK GAS TYPE

not natural gas, do not install fireplace. Call
dealer where you bought fireplace for proper
type fireplace.

vice person must install fireplace.
