Side Wall Termination Assembly
1. Locate the vent opening on the wall. Refer to Figure 5,
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 openings must be framed
as shown in Figure 22.

(Simpson Dura-Vent Components)
1.
Install the Restrictor Plate:
Consult Page 9 to determine
whether the restrictor plate is needed. If so, place the
restrictor plate into the inner flue collar. (Figure 16)
2.
Discard the inner starter pipe
shipped with the logset.
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. (Figure 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. (Figure 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.
