b) Horizontal runs of vent must be sup-
portedeverythreefeet. Wall straps are
available for this purpose.
5) Mark the wall for a 10" x 10" square hole.
Thecenterofthesquareholeshouldlineup
with the centerline of the horizontal pipe.
Cutandframethe10inchsquareholeinthe
exterior wall where the vent 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)
diameter (7-1/2"(191mm) dia. for flex) hole
is acceptable. See Horizontal Termination
diagram on page 14.
Note: With Dura-Vent, the minimum
height is achieved by installing a
90oelbow directly to the flue adapt-
er.
Note:
a) Thehorizontalrunofventmustbelevel,
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,
andmustnotbe blocked or obstructed.
For External Vent Terminal Locations,
see diagram on page 9.
c) Snorkel Terminations:
Forinstallationsrequiringaverticalrise
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
standardHorizontalTermination.NEV-
ER install the snorkel upside down.
*As specified in CGA B149 Installation Code.
Local codes or regulations may require differ-
ent clearances.

Below Grade Snorkel Installation
If the Snorkel Termination must be in-
stalled below grade, i.e. basement ap-
plication, proper drainage must be pro-
vided to prevent water from entering
theSnorkelTermination.RefertoDura-
Vent Installation instructions for de-
tails. 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" clear-
ances to combustible materials are main-
tained (Dia. 3). Install the termination cap.
AstroCapTM or Dura-Vent Horizontal Ter-
mination Cap may be used.

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 at-
tached. 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
andtheelectrical(junctionblockisontheleft
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.
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
fastenit to the framingusingnailsor 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-lockprocedure:Fourindentations,
locatedon thefemaleendsofpipesand

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,

ly together, then twist-lock one section
clockwise approximately one-quarter
turn, until the two sections are fully
locked. The female locking lugs will not
bevisible from the outside,on theBlack
Pipe or fittings. They may be located by
examiningtheinsideofthefemaleends.
Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature sili-
cone sealant to outer pipe on eve-
ry 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 stand-
off 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
WallThimble(Part#620-926)overthevent
pipe.
8) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
