U39 ULTIMATE Direct Vent Freestanding Gas Stove
INSTALLATION
Note: if the centerline cannot be met,
the adjustable sections will have to
be cut.
e) Cut the 2 ft. or 4 ft. section of rigid pipe
to length. Ensure that the pipe length
when cut will seat onto both the starter
collar and the 90
o
elbow. Crimped
section of rigid pipe seats into the
90
o
elbow. Only cut the uncrimped
side of pipe.
Dismantle all pipe sections including vent
terminal.
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
(stainless steel).
4) Attach the adjustable pipe section to the vent
terminal using Mill-Pac and attach with 3 of
the #8 x 1/2" screws (stainless steel).
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. 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" 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) and the
2 ft. or 4 ft. pipe section (crimp end up) over
the 4" dia. fl ex liner.
12) Slide the trim collar over the adjustable pipe
sections to cover the joint of the telescopic
section.
13) Install the spring spacers onto the pipe
sections.
14) Secure the 4" dia. fl ex 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).
15) Attach the pipe section onto the starter
collar by sealing with Mill-Pac and/or high
temperature silicone and securing with 3 of
the #8 x 1/2" (black) screws. 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
temperature silicone and securing with 3
of the #8 x 1/2" screws (black).
17) Slide the adjustable pipe section onto the 90
o
elbow. 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.
NOTE: For best results and optimum perfor-
mance with each approved venting system,
it is highly recommended to apply “Mill-Pac”
sealant (supplied) to every inner pipe connec-
tion. Failure to do so may result in drafting
or performance issues not covered under
warranty. Silicone (red RTV) is optional.
Note: To make the installation more
aesthetically pleasing, we recommend
framing out a square that the
cap can be mounted
on.
Note: I f 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
installation refer to the Dura-Vent
Termination instructions.
5) Slide the partially connected 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.
Note: The pipe seam should be facing
down.
