Install the Vent Adapter Pipe
(Simpson Dura-Vent Components)
1. Install the Restrictor Plate. Consult the ‘Vent Run
Specifications’ on Page 8 to determine whether the
restrictor plate is needed. If so, put the restrictor
plate in place within 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 verti-
cal seam to the rear, and insert the crimped end of
the outer pipe into the flue collar. Fasten with three
sheet metal screws provided.

Side Wall Termination Assembly
1. Locate the vent opening on the wall. Refer to Fig-
ure 5, Page 6, 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. Com-
bustible wall openings must be framed as shown in
Figure 22.
