4) Attach the adjustable pipe section to the vent
terminal using Mill-Pac and/or high temperature
silicone and attach with 3 of the #8 x 1/2" screws
(stainless steel).
NOTE: For best results and optimum performance
with each approved venting system, it is
highly recommended to apply "Mill-Pac"
sealant (supplied) to every inner pipe
connection. Failure to do so may result
in drafting or performance issues not
covered under warranty. Silicone (red
RTV) is optional.
Note: The pipe seam should be facing down.
Note: To make the installation more aestheti-
cally pleasing, we recommend framing
out a square that the cap can be mounted
on.
Note: If installing termination on a siding
covered wall, a vinyl siding standoff or
furring strips must be used to ensure that
the termination is not recessed into the
siding. For vinyl siding standoff instal-
lation refer to the Dura-Vent Termination
instructions.

5) Slide the partially con-
nected pipe and vent
terminal assembly through
the wall thimbles (from the
exterior into the interior)
and secure the cap to the
exterior wall with 4 of the
supplied screws (#8 x 1-1/2" drill point, stainless
steel). Note: pilot holes will need to be drilled
through the wall thimble on all 4 corners.
Note: The four screws provided for the vent
cap should be replaced with appropriate
fasteners for stucco, brick, concrete, or
other types of sidings.
6) A bead of non-hardening mastic should be run
around both the termination and vinyl siding
standoff to prevent water from entering and
to make a tight seal between the cap and the
standoff.
7) Stretch the 4" dia. flex liner out fully and get a
trial fit of the liner onto the 4" dia. starter collar.
8) Cut the 4" dia. flex liner to the desired size.
Hint: leave an extra 12" to 16" of length, this
will make the final assembly easier to work with.
9) Secure the 4" dia. flex liner to the 4" adapter
with Mill-Pac and 3 of the #8 x 1/2" screws
(stainless steel).
10) Slide the decorative Thimble Cover over the
pipe sections and secure with 4 screws (#8 x
1-1/2" drill point, black) to the wall.
11) Slide the 90
elbow (crimp end up), the 45
o
elbow and the 4 ft. pipe section (crimp end up)
over the 4" dia. flex liner.
12) Install the spring spacers onto the pipe sections.
13) Secure the 4" dia. flex liner with adapter onto
the stove collar. Put a bead of Mill-Pac around
the appliance adapter and secure with 3 screws
(#8 x 1/2, stainless steel).
14) Attach the 45
sealing with Mill-Pac and/or high temperature
silicone and securing with 3 of the #8 x 1/2"
(black) screws.
15) Attach the pipe section to the 45
sealing with Mill-Pac and/or high temperature
silicone and securing with 3 of the #8 x 1/2"
screws (black). Pipe seams should be facing
the wall.
16) Attach the 90
sealing with Mill-Pac and/or high temperature
silicone and securing with 3 of the #8 x 1/2"
screws (black).
17) Slide the adjustable pipe section onto the 90
elbow. Slide the trim collar over the adjustable
pipe sections to cover the joint of the telescopic
section.) The flex may have to be compressed
back in order for the adjustable pipe to properly
mate to the elbow. Seal with Mill-Pac and/or
high temperature silicone and secure with 3 of
