Assembly steps f
Wall Installation on an Interior Partition Wall):
1. An unobstructed wall pass-through is required
to allow for a safe installation of the fireplace
vent components. This will necessitate removal
of a portion of the interior wall covering (e.g.
sheetrock or plaster and lath), on both sides of
the partition wall and any adjacent internal wall
materials (like insulation).

1. The fireplace mounting plate is attached to th
wall structure using four ¼” X 1½”
and large diameter washers that are provided
with the fireplace. It is important to use the
included hardware as the full weight of the
fireplace is supported by the mounting plate.
Drill a 5/32” diameter pilot hole at each of
mounting hole locations marked using the
template. The pilot holes should be the full
depth of the lag bolts. Be sure that there is so
wood at each mounting location. If not,
