Horizontal Installation�
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 24). 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 20 and Table 3. 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 25).
