4. Slip the wall cover over the interior end of the horizontal
pipe and install into the zero clearance sleeve. Seal the
joint inside the wall plate if needed to keep cold air from
being drawn into the home.
5. Install the vent terminal, Figure 3.21. Guide the inner and
outer vent termination collars into the adjacent pipes.
Double check that the vent pipes overlap the collars by 2".
Fasten the termination to the outside wall with the screws
provided, and caulk the joint with weatherproof sealant.
6. Use wall straps to support vertical pipe runs at 8' (2.4 m)
intervals.
Horizontal Installation
Step 1 - Set the gas appliance in its desired location. Check
to determine if wall studs or roof rafters are in the way once
the venting system is attached. If this is the case, you may
want to adjust the location of the appliance.
Step 2 - DirectVent Pro pipe, SLP pipe and fittings are
designed with special twist-lock connections. To connect
the venting system to the appliance flue outlet, a twist-lock
appliance adaptor is built into the appliance at the factory.
Assemble the desired combinations of black pipe sections
and elbows to the appliance adapter with pipe seams
oriented towards the wall or floor, as much out of view as
possible, Figure 3.23.
Figure 3.23
NOTES:
1. Twist-lock procedure: Line up locking lugs on male and
female ends of pipe sections. Insert the male end of pipe
into the female end until the locking lugs are covered.
Twist the female end clockwise an eighth of a turn to lock
sections together, Figure 3.24. Screws are not required
to secure the joint, but are acceptable provided they do
not penetrate the inner wall of the vent pipe.

2. Horizontal vent runs of vent pipe must be supported to
prevent any downward sags. Horizontal pipe sections
should be supported at least every 5' (1.5 m). Wall straps
can be used for this purpose. Alternatively, plumbers
tape or other suitable noncombustible material can be
used to support the vent pipe.
3. DirectVent Pro and SLP venting requires no sealant.
Step 3 - With the appliance adapter and pipe section
attached, slide the stove into its correct location. Mark the
wall for a square hole that measures 10" x 10" (254 x 254
mm). The centerline of the pipe should line up with the center
of the square hole, Figure 3.25. Cut and frame the square
hole in the exterior wall where the vent will be terminated. If
the wall being penetrated is constructed of noncombustible
material only, i.e. masonry block, brick or concrete only, a
hole with zero clearance is acceptable.

NOTES:
1. The horizontal run of venting must be level, or have a
1/4" (6 mm) rise for every 1' (305 mm) of run toward
the termination. Never allow the vent to run downward.
A downward slope can trap heat and become a possible
fire hazard.
