HORIZONTAL
TERMINATIONS
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 connect 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. Install the adaptor after the unit is
set in its desired location otherwise the unit
will not fi t 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 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.
(Diagram 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: For best results and optimum
performance with each approved venting
system, it is highly recommended to apply
"Mill-Pac" sealant (supplied) to every in-
ner pipe connection. Failure to do so may
result in drafting or performance issues not
covered under warranty. Silicone (red RTV)
is optional.

b) Horizontal runs of vent must be
supported every 3 feet (0.9meter). Wall
straps are available for this purpose.
5) Mark the wall for a 10" x 10" (254mm x
254mm) square hole. The center of the
square hole should line up with the center-
line of the horizontal pipe. Cut and frame the
10 inch (254mm) 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" (190mm) for fl ex) 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 fi re.
b) The location of the horizontal vent
termination 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 in the "Exterior
Vent Termination Locations" section.
c) Snorkel Terminations:
For installations requiring a vertical rise
on the exterior of the building, 14-inch
and 36-inch tall Snorkel Terminations
(diagram 3 & 4) are available, as well
as the standard Riser Vent, diagram 3a.
Follow the same installation procedures
as used for standard Horizontal
Termination. NEVER install the snorkel
upside down.
NOTE: For Snorkel terminations in ABOVE
grade installations, follow national or
local code requirements.
INSTALLATION
*Diagrams 3, 3a & 4: As
specifi ed in CGA B149
Installation Code. Local
codes or regulations
may require different
clearances.
Diagram 3
Note: Riser Vent
is only for use
in above grade
terminations.
Below Grade 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 Diagram 4.
Do not attempt to
enclose the Snorkel
within the wall, or
any other type of
enclosure.
