INSTALLATION
3) Attach the 4" dia. flex liner to the vent
terminal ensuring that the flex overlaps the
collar of the vent terminal by a minimum of
1-3/8"(35mm). Use Mill-Pac to seal and
secure with 3 of the #8 x 1/2" screws
(stainless steel).
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).
Hint: Apply the sealant (Mill-Pac and/or high
temperature silicone) to the outer pipe before
connecting the inner pipe.
Note: The pipe
s e a m
should be
f a c i n g
down.
Note: To make the installation more aes-
thetically pleasing, we recom-
mend framing out a square that
the cap can be mounted on.
Note: If installing ter-
mination on a
siding covered
wall, a vinyl sid-
ing standoff or
f u r r i n g s t r i p s
must be used to
ensure that the
termination is
not recessed into the siding. For
vinyl siding standoff installation
refer to the Dura-Vent Termina-
tion instructions.

5) Slide the partially connected pipe and vent
terminal assembly through the wall thim-
bles (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 o elbow (crimp end up), the 45
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 elbow onto the starter collar
by sealing with Mill-Pac and/or high tem-
perature 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 tempera-
ture silicone and securing with 3 of the #8
x 1/2" screws (black). Pipe seams should
be facing the wall.

16) Attach the 90 elbow onto the pipe section
by sealing with Mill-Pac and/or high tem-
perature silicone and securing with 3 of the
#8 x 1/2" screws (black).
17) Slide the adjustable pipe section onto the
o
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
the #8 x 1/2" screws (black). Pipe seams
facing down.
18) Install the trim collar over the starter collar
and secure with a #8 x 1/2" screw (black).
If the pipe needs to be touched up, use only
Stove Brite High Temperature Metallic Black
Stove Paint.
NOTE: All inner joints must be sealed
with Mill-Pac. All outer joints may
be sealed with high temperature
silicone.
