INSTALLATION
HORIZONTAL
INSTALLATIONS
Install the flue 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 flueing system is at-
tached. If this is the case, you may want to
adjust the location of the unit. Rough in the
gas.
2) Direct Flue pipe and fittings are designed
with special twist-lock connections to con-
nect the flueing system to the appliance flue
outlet. A twist-lock appliance adaptor is an
available option that must be used in con-
junction with the Simpson Dura-Vent Direct
Vent GS system.
3) Put a bead of silicone inside the outer section
of the adapter and a bead of Mill Pac on the
inner collar. Slip the adapter over the exist-
ing 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 indentations,
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 inden-
tations so they match and slide in to the
four entry slots on the male ends, Dia-
Diagram 1
b) Horizontal runs of flue 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 flue will be termi-
nated. If the wall being penetrated is con-
structed of non-combustible material, i.e.
masonry block or concrete, a 7"(178mm)
dia. (7-1/2"(191mm) dia. for flex) hole is
acceptable.
Note: With Dura-Vent, the minimum height
is achieved by installing a 45 o elbow di-
rectly to the flue adaptor.

Note:
a) The horizontal run of flue must be level,
or have a 1/4 inch rise for every 1 foot
of run towards the termination. Never
allow the flue to run downward. This
could cause high temperatures and
may present the possibility of a fire.
b) The location of the horizontal flue termi-
nation on an exterior wall must meet all
local and national building codes, and
must not be blocked or obstructed. For
External Flue Terminal Locations, see
diagram on page 12.
6) The arrow on the flue cap should be
pointing up. Insure that the 1-1/2" clear-
ances to combustible materials are main-
tained (Diagram 3 on page 16). Install the
termination cap.
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 stand-
off or furring strips must be used
Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature sili-
cone sealant to outer pipe on eve-
ry twist-lock joint.

gram 1. Push the pipe sections com-
pletely 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 fittings. They may be
located by examining the inside of the
female ends.

minimum of 5 feet total vertical and maximum 12 feet total horizontal.
Please note minimum 1 foot between 90 o elbows is required.
