9) Install wall thimble in the center of the 11"
(279mm) square and attach with wood
screws (Diagram 7).

6) The arrow on the vent cap should be
pointing up. Insure that the 1-1/4"(32mm)
clearances to combustible materials are
maintained (Diagram 5). Install the termina-
tion cap.
Note: If installing termination on a siding
covered wall, a vinyl siding stand-
off or furring strips must be used
to ensure that the termination is
not recessed into the siding.
The four wood screws provided should be
replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
7) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
Wall Thimble (Part # 1247) over the vent
pipe.
8) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
pipe into the vent cap assembly. It is impor-
tant that the vent pipe extends into the vent
cap sufficient distance so as to result in a
minimum pipe overlap of 1-1/4 inches
(32mm). Secure the connection between
the vent pipe and the vent cap by attaching
the two sheet metal strips extending from
the vent cap assembly into the outer wall of
the vent pipe. Use the two sheet metal
screws provided to connect the strips to
the pipe section. See Diagram 6.
INSTALLATION
HORIZONTAL
INSTALLATIONS
Install the vent system according to the manu-
facturer's instructions included with the com-
ponents.
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 fittings are designed
with special twist-lock connections to con-
nect the venting system to the appliance
flue 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. Install the adaptor
after the unit is set in its desired location
otherwise the unit will not fit through the
36-5/8" (930mm) high frame opening.
3) Put a bead of silicone inside the outer
section of the adapter and a bead of Stove
Mate on the inner collar. Slip the adapter
over the existing inner and outer flue collar
and fasten to the outer collar only with the
3 supplied screws (drilling pilot holes will
make this easier). Level the fireplace 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 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.
Diagram 1
They may be located by examining the
inside of the female ends.
Note: Apply sealant "Mill-Pac" to inner
pipe and high temp silicone seal-
ant to outer pipe on every twist-
lock joint.
b) Horizontal runs of vent must be sup-
ported every 3 feet (0.9meter). Wall
straps are available for this purpose.
5) Mark the wall for a 11" x 11" (279mm x
279mm) square hole. The center of the
square hole should line up with the center-
line of the horizontal pipe. Cut and frame the
11 inch (279mm) 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 8" (203mm) diameter
hole is acceptable.
Diagram 2
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 fire.
b) The location of the horizontal vent ter-
mination 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 11.
