INSTALLATION
DURA-VENT VENTING
COMPONENTS
The Simpson Dura-Vent Direct Vent System
offers a complete line of component parts for
installation of both horizontal and vertical instal-
lation. Many items are offered in decorative
black, as well as galvanized finish. The galva-
nized pipe and fittings are used for concealed
locations such as attics or where corrosion is
a factor, such as above the roof line. Decora-
tive brass trim kits are available for both wall
thimbles and ceiling support boxes.

HORIZONTAL
INSTALLATIONS
1)
Set the unit in its desired location. Check to
determine if wall studs or roof rafters are
in the way when the venting system is
attached. If this is the case, you may want
to adjust the location of the unit.
2)
Direct Vent pipe and fittings
are designed with special
twist-lock connections to
connect the venting sys-
tem to the appliance flue
outlet. A twist-lock appli-
ance adapter is installed
on the unit at the factory.
Assemble the
desired combi-
nation of pipe
and elbows to
the appliance
adapter with
pipe seams
oriented to-
b)
Horizontal runs of vent must be sup-
ported every three feet. Wall straps are
available for this purpose.
c) Snorkel Terminations:
For installations requiring a vertical rise
on the exterior of the building, 14-inch
and 36-inch tall Snorkel Terminations
and the Riser Vent as shown in Dia. 2
& 2a are available. Follow the same
installation procedures as used for
standard Horizontal Termination. NEV-
ER install the snorkel upside down.

You will require the following components with
your new Direct Vent Freestanding Gas Stove.
Please review your product to make sure you
have everything you need. In the event that you
are missing any part, contact your dealer.
Note: These are the minimum pieces
required. Other parts may be re-
quired for your particular installa-
tion. See above for a list of vent
parts.
If installing termination on a siding covered wall,
a vinyl siding standoff or furring strips can be
used in order to ensure that the termination is
not recessed into siding.
The vinyl siding standoff is required for walls
with vinyl siding.
Minimum components for a Dura-Vent
Horizontal Installation:
A) Dura-Vent Horizontal Termination Kit
B) Wall Thimble (required for combustible
walls)
Minimum components for a Dura-Vent
Vertical Termination:
D) Dura-Vent Vertical Termination Kit. See
above for pipe lengths.
wards the wall or ceiling, as much out of
view as possible. The final positioning of
the pipe and 90
o
elbow assembly is deter-
mined by the mounting orientation of the
adapter on the stove and twist-locked for
a solid connection.
Note:
a)
Twist-lock procedure: Four indenta-
tions, 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 in to the four entry slots on the
male ends (diagram 1). Push the pipe
sections completely together, then
twist-lock one section clockwise ap-
proximately one-quarter turn, until the
two sections are fully locked. The fe-
male locking lugs will not be visible from
the outside on the Black Pipe or fittings.
They may be located by examining the
inside of the female ends. Apply seal-
ant "Mill-Pac" to inner pipe and high
temp silicone sealant to outer pipe on
every twist-lock joint.
