Final Finishing
Noncombustible materials such as brick and tile can be
extended over the face of the unit (Do not cover the
glass door or grilles) If a Trim Kit is to be installed,
brick and tile will have to be installed flush with the side
of this appliance.
Framing and Finishing
Check fireplace to make sure it is lev-
elled and properly positioned.

secure it firmly in place, remove the nailing flanges
from the hearth and install at the sides of the fire-
place as shown in Figure 3.
3. Screw through the slotted holes in the drywall strip
and into pre-drilled holes in fireplace side. Measure
from face of fireplace to the face of the drywall strip
to confirm the final depth.
