1. Install the Restrictor Plate. Consult Page 9 to deter-
mine whether the restrictor plate is needed. If so, place
the restrictor plate into the inner flue collar. (Fig. 16)
2. Discard the inner starter pipe shipped with the log-
set. Using the starter pipe assembly listed on Page 7,
slide the inner section out to allow access.
• Run a bead of sealant around the bottom end of the
starter pipe and attach the assembly to the stove using
three 1/4-20 x 3/8" Phillips screws provided in the parts
bag. (Fig. 20)
3. Install the Outer Adapter Pipe. Apply a 1/4" bead of
cement around the outside surface, about one inch
from the crimped end. (Fig. 21) Orient the vertical
seam to the rear, and insert the crimped end of the
outer pipe into the flue collar. Fasten with three sheet
metal screws provided.

1. Locate the vent opening on the wall. Refer to Figure 5,
Page 7, to determine the opening centerline. It may be
necessary to first position the stove and measure to
find the hole location. Depending on whether the wall
is made of combustible materials, cut the opening to
the size shown in Figure 22. Combustible wall open-
ings must be framed as shown in Figure 22.
