Horizontal Installation - Vermont Castings Intrepid INDVRCB Homeowner's Installation And Operating Manual

4. Slip the wall cover over the interior end of the hori-
zontal 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. (Fig. 22) 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 4'
(1219 mm) 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 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 fac-
tory. 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. (Fig. 24)
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. (Fig. 25)
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 sec-
tions should be supported at least every 4' (1.2 m).
Wall straps can be used for this purpose. Alternative-
ly, plumbers tape or other suitable noncombustible
material can be used to support the vent pipe.
3. DirectVent Pro venting requires no sealant.
Step 3. With the appliance adapter and pipe section at-
tached, 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. (Fig. 26) Cut and frame
the square hole in the exterior wall where the vent will
be terminated. If the wall being penetrated is con-
structed 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.
