INSTALLATION

HORIZONTAL INSTALLATIONS
Diagram 1
b) Horizontal runs of vent must be sup-
ported every three feet. Wall straps are
available for this purpose.
5) Mark the wall for a 10" x 10" square hole.
The center of the square hole should line
up with the centerline of the horizontal pipe.
Cut and frame the 10 inch square hole in
the exterior wall where the vent will be
terminated. If the wall being penetrated is
constructed of non-combustible material,
i.e. masonry block or concrete, a 7"(178mm)
diameter (7-1/2"(191mm) dia. for fl ex) hole
is acceptable.
Note:
a) The horizontal run of vent must be level,
or have a 1/4 inch rise for every 1 foot
of run towards the termination. Never
allow the vent to run downward. This
could cause high temperatures and
may present the possibility of a fi re.
b) The location of the horizontal vent termi-
nation on an exterior wall must meet all
local and national building codes, and
must not be blocked or obstructed. For
External Vent Terminal Locations, see
diagram on page 9.
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 instal-
lation procedures as used for standard
Horizontal Termination. NEVER install
the snorkel upside down.
*As specifi ed in CGA B149 Installation Code.
Local codes or regulations may require differ-
ent clearances.

Below Grade Snorkel Installation
If the Snorkel Termination must be
installed below grade, i.e. basement
application, proper drainage must be
provided to prevent water from enter-
ing the Snorkel Termination. Refer to
Dura-Vent Installation instructions for
details. Do not attempt to enclose the
Snorkel within the wall, or any other type
of enclosure.
6) The arrow on the vent cap should
be pointing up. Insure that the 1-1/2"
clearances to combustible materials are
maintained (Dia. 3). Install the termination
cap. AstroCap
TM
or Dura-Vent Horizontal
Termination Cap may be used.
Diagram 2a
Install the vent system according to the
manufacturer's instructions included with the
components.
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. Rough in
the gas preferably on the right side of the
unit and the electrical (junction block is on
the left side) on the left.
2) Direct Vent pipe and fi ttings are designed
with special twist-lock connections to con-
nect the venting system to the appliance
fl ue outlet. A twist-lock appliance adaptor
is an available option that must be used in
conjunction with the Simpson Dura-Vent
Direct Vent GS system.
3) Put a bead of silicone inside the outer sec-
tion of the adapter and a bead of Stove
Mate on the inner collar. Slip the adapter
over the existing inner and outer fl ue collar
and fasten to the outer collar only with the
3 supplied screws (drilling pilot holes will
make this easier). Level the fi replace and
fasten it to the framing using nails or screws
through the nailing strips.
4) Assemble the desired combination of pipe
and elbows to the appliance adaptor and
twist-lock for a solid connection.
Note:
a) Twist-lock procedure: Four indentations,
located on the female ends of pipes and
fi ttings, are designed to slide straight
onto the male ends of adjacent pipes
and fi ttings, by orienting the four pipe
indentations so they match and slide
in to the four entry slots on the male
ends, Dia. 1. Push the pipe sections
completely together, then twist-lock
one section clockwise approximately
one-quarter turn, until the two sections
are fully locked. The female locking lugs
will not be visible from the outside, on
the Black Pipe or fi ttings. They may be
located by examining the inside of the
female ends.
Note: Apply sealant "Mill-Pac" to inner pipe
and high temperature silicone seal-
ant to outer pipe on every twist-lock
joint.
The four wood screws provided should
be replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
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.
7) Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble (Part # 620-926) over the vent
pipe.
8) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
