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 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 Flue pipe and fittings are designed with
special twist-lock connections to connect the
flueing 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-Flue Direct Flue GS system.
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 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 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 fittings. They may be located by
examining the inside of the female ends.
Note: Apply sealant "Mill-Pac" to inner pipe
and high temperature silicone sealant
to outer pipe on every twist-lock joint.
b) Horizontal runs of flue must be supported
every three feet. Wall straps are available
for this purpose.
5) Mark the wall for a 10" (254mm) x 10" (254mm)
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 constructed
of non-combustible material, i.e. masonry
block or concrete, a 7"(178mm) diameter (7-
1/2"(191mm) dia. for flex) hole is acceptable.
Note:
a) The horizontal run of flue must be level, or
have a 1/4" (6.3mm) rise for every 1 foot
(0.3m) 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 termina-
tion 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
10.
c) Snorkel Terminations:
For installations requiring a vertical rise on
the exterior of the building, see Diagram 2.
Follow the same installation procedures as
used for standard Horizontal Termination.
6) The arrow on the flue cap should be point-
ing up. Insure that the 1-1/2" clearances to
combustible materials are maintained. 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 cov-
ered wall, a vinyl siding standoff or
furring strips must be used to ensure that the ter-
mination is not recessed into the siding.
7) Before connecting the horizontal run of flue pipe
to the flue termination, slide the Wall Thimble
(Part # 620-926) over the flue pipe.
installation
8) Slide the appliance and flue assembly towards
the wall carefully inserting the flue
pipe into the flue cap assembly. It is important
that the flue pipe extends into the flue cap suf-
ficient distance so as to result in a minimum
pipe overlap of 1-1/4" (32mm). Secure the
connection between the flue pipe and the flue
cap 3 sheet metal screws.
9) Install wall thimble in the center of the 10"
(254mm) square and attach with wood screws
(Diagram 3).

*As specified in CGA B149 Installation Code.
Local codes or regulations may require different
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 entering the Snorkel
Termination. Refer to Dura-Flue Installation
instructions for details. Do not attempt to
enclose the Snorkel within the wall, or any
other type of enclosure.
