the outside, on black pipe. They may be located by examining the inside of the female ends as shown
in Figure 31.
Notes:
(a) Twist-lock procedure: four (4) indentations, located on the female end of the pipes and fittings, are
designed to slide straight onto the male ends of adjacent pipes and fittings, by orienting the four pipe
indentations so they match and slide into the four entry slots on the male end.
(b) Horizontal runs of vent pipe must be supported every 36” (915mm). Wall straps are available for this
purpose, also when running horizontal pipe minimum clearances to combustibles must be maintained;
2” (51mm) at top, 1½” (38mm) at sides, 1½” (38mm) at bottom.
3. With the pipe attached to the stove in the correct location,
mark the wall for a 10” (25.4cm) x 10” (25.4 cm) square hole
(refer to Figure 32). The center of the square hole should
match the center line of the horizontal pipe. Cut and frame the
10” (25.4cm) x 10” (25.4cm) hole in the exterior wall where
the vent will be terminated. Refer to Figure 23 and Table 7. If
the wall being penetrated is constructed of non-combustible
material i.e. masonry or concrete, a 7” (17.8cm) hole is
acceptable.
4. Position the horizontal vent termination in the center of the
10” (25.4cm) x 10” (25.4cm) hole, and attach to the exterior
wall with the four screws provided. Before attaching the vent
termination to the exterior wall, run a bead of non-hardening
mastic around the edges, so as to make a seal between the
termination and the wall. The arrow on the vent termination
should be pointing up, insure that the proper clearances to
combustible materials are maintained.
5. Before connecting the horizontal run of the vent pipe to the
vent termination, slide the black decorative wall thimble cover over the vent pipe.
6. Slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the
cap assembly. It is important that the vent pipe extend into the vent cap a sufficient distance with a
minimum of 1¼” (3.2cm) overlap. Secure the connection between the vent cap pipe and the vent cap

by attaching the two sheet
metal straps extending from
the vent cap assembly into
the outer wall of the vent
pipe. Use the two sheet
metal screws provided
to connect the straps to
the vent pipe. Bend any
remaining portion of the
sheet metal straps back
towards the vent cap, so
the decorative wall thimble
will conceal it (see left
image in Figure 33).
