Step 4.
Position the horizontal vent termination in the center of the 10" x 10" (25.4cm x 25.4cm) square hole and run a bead of non-hardening
mastic around its outside edges, so as to make a seal between it and the wall, attach termination cap to the exterior wall with the four
wood screws provided. The arrow on the vent cap should be pointing up (
Fig. 7
)

NOTES:
(
1) The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types
of sidings.
(2) Termination Cap HHW2 (HTI Part #841-0670) is highly recommended on a building with vinyl siding, as the vinyl siding
standoff is built in. The pilot hole will be 2 inches closer to the bottom of the square than the top. Using a framing square,
draw a 14" x 14" square around the pilot hole.
See Fig. 8-A
.
(
NOTE:
If you are installing Termination Cap HHW2, the pipe
will be off center on the flashing). Ensure that proper clearances to combustible materials are maintained.
If you are using
Simpson Dura-vent termination cap #985 on a building with vinyl siding, a vinyl siding standoff (Simpson Dura-vent
Part #950), should be installed between the vent cap and the exterior wall (
Fig. 8-B
). Attach the vinyl siding standoff to
the horizontal vent termination. The vinyl siding standoff prevents excessive heat from possibly melting the vinyl siding
material. Vent terminal shall not be recessed into a wall or siding. Remove siding from behind area of standoff.
Step 5.
Slide the stove and vent assembly towards the wall,
carefully inserting the vent pipe into the vent cap assembly.
It is important that the vent pipe extend into the vent cap
a sufficient distance so as to result in a minimum pipe
overlap of 11⁄4” (32mm). Secure the connection between
the vent pipe and the vent cap by attaching the two sheet
metal strips extending from the vent cap assembly into
the outer wall of the vent pipe. Use the two sheet metal
screws provided to connect the strips to the pipe section
(
Fig. 9).
FIG. 9
Note:
The attachment from the vent pipe to the vent cap
must be sealed with silicone. Venting terminals shall not
be recessed into a wall or siding.
