Step 1. Determine the desired location of the fireplace.
Check to ensure that wall studs or roof rafters
are not in the way when the venting system is
attached. If this is the case, you may want to
adjust the location of the stove.
Step 2. Simpson Dura-Vent pipe is designed with special
twist-lock connections. To connect the venting
system to the stove flue outlet, a twist-lock
adapter is built into the stove at the factory.
Remember to include wall thickness in minimum
clearances when figuring the measurements for
your installation needs.
HORIZONTAL INSTALLATION
NOTE:
1. Horizontal sections require a 1/4" (6mm) rise
for every 1’ (305mm) of horizontal travel. Never
allow the vent to run downward. This could
cause high temperatures and may present the
possibility of a fire.
2. Exterior Vent Diameter = 6 5/8" (177mm);
3. Inner Vent Diameter = 4" (101mm)
4. Horizontal sections require noncombustible
support every 3' (914mm) , e.g. plumbing tape.
5. The location of the horizontal vent termination on
an exterior wall must meet all local and national
building codes, and must not be easily blocked
or obstructed, see page 19.
6. For installations requiring a vertical rise on the
exterior of the building, 14" (356mm) and 36"
(914mm) tall snorkel terminations are available.
Follow the same installation procedures as
used for standard horizontal terminations.
If the snorkel termination must be installed
below grade (i.e. basement application), proper
drainage must be provided to prevent water
from entering the snorkel termination. Do not
backfill around snorkel termination.

MALE LOCKING LUGS
FIG. 5
FIG. 6
Note: Twist-lock procedure: Four indentations, located on
the female ends of 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 ends, see Fig.5 below.
Push the pipe sections completely together, then twist-lock
one section clockwise approximately one-quarter turn, until the
two sections are fully locked. The female locking lugs will not
be visible from the outside, on the pipe or fittings. They may be
located by examining the inside of the female ends.
Step 3. With any vertical pipe required for your installation,
and the 45° elbow attached to the flue outlet,
measure the distance from the base of the ZC
appliance to the center of the 45° elbow, adding
1/4" rise for every 1' of horizontal venting, as
referenced in Note 1, below. Measure this height
at the correct wall location for your installation,
maintaining minimum clearance to combustibles,
and mark the wall for a 10" x 10" (254mm x 254mm)
square hole. The center of the square hole should
line up with the centerline of the horizontal pipe,
as shown in Figure 7. Cut and frame the hole in
the exterior wall where the vent will be terminated.
If the wall being penetrated is constructed of
noncombustible material, i.e. masonry block
or concrete, a 7" (178mm) diameter hole is
acceptable.
