1� Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the
way when the venting system is attached. If this is the case, you may want to adjust the location of
the appliance.
2�
Direct vent pipe and fittings are designed with special twist-lock connections. Assemble the desired
combination of black pipe and elbows to the appliance adapter with pipe seams oriented towards the
wall or floor, as much out of view as possible.
Note:
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 25). 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 25. 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 26).
7� Slide the decorative wall
thimble up to the wall surface
and attach with the screws
provided. Apply decorative
brass or chrome trim if
desired (see right image in
Figure 26).
