3. Attach vent pipe assembly to the
burner system. Set stove in front of its
permanent location to ensure
minimum clearances. Mark the wall
for a 10" square hole (for
noncombustible material such as
masonry block or concrete, a 7 ½"
diameter hole is acceptable). See
Figure 21. The center of the hole
should line up with the center line of
the horizontal rigid vent pipe. Cut a
10" x 10" (254mm x 254mm) square
hole through combustible exterior
wall (7 ½" [190mm] diameter hole if
noncombustible). Frame as necessary.
4. Apply a bead of non-hardening
mastic around the outside edge of
the vent cap. Position the vent cap
in the center of the 7 ½" or 10" hole
on the exterior wall with the “up”
on the vent cap facing up. Ensure
proper clearance of 1" to
combustibles is maintained. Attach
the vent cap with four wood screws
supplied (see Figure 22). Note:
Replace the wood screws with
appropriate fasteners for stucco,
brick, concrete, or other types of
siding.
For vinyl siding, stucco, or wood
exterior use vinyl siding standoffs
between vent cap and exterior wall.
The vinyl siding standoff prevents
excessive heat from melting the
vinyl siding material. Bolt the vent
cap to the standoff. Apply non-
hardening mastic around outside
edge of the standoff instead of the
vent cap assembly. Use wood
screws provided to attach the
standoff. See Figure 23.
5. Slide the wall thimble over the vent
pipe before connecting the
horizontal run to the vent cap (see
Figure 24).
6. Carefully move the stove with vent
assembly attached toward the wall
and insert the vent pipe into the
horizontal termination. The pipe
overlap should be a minimum of
1 ¼". Apply silicone to the outer
pipe connection. Fasten all vent
connections with screws provided.
7. Slide the wall thimble against the
interior wall surface and attach with
screws provided (see Figure 24).
WARNING: Do not recess vent
termination into any wall. This will
cause a fire hazard.
