INSTALLATION
3) Attach the 4" dia. fl ex liner to the vent
terminal ensuring that the fl ex 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 (stain-
less 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).
NOTE: For best results and optimum per-
formance 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 aes-
thetically pleasing, we recommend
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
Termination 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 ap-
propriate 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 enter-
ing and to make a tight seal between the
cap and the standoff.
7) Stretch the 4" dia. fl ex liner out fully and get
a trial fi t of the liner onto the 4" dia. starter
collar.
8) Cut the 4" dia. fl ex liner to the desired size.
Hint: leave an extra 12" to 16" of length, this
will make the fi nal assembly easier to work
with.
9) Secure the 4" dia. fl ex liner to the 4" adaptor
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
elbow and the 4 ft. pipe section (crimp end
up) over the 4" dia. fl ex liner.
12) Install the spring spacers onto the pipe
sections.
13) Secure the 4" dia. fl ex liner with adaptor
onto the stove collar. Put a bead of Mill-Pac
around the appliance adaptor 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
o
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
90
o
elbow. Slide the trim collar over the
adjustable pipe sections to cover the joint
of the telescopic section.) The fl ex 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.
