INSTALLATION
UNIT INSTALLATION WITH HORIZONTAL TERMINATION
Install the vent 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 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 system.
3. Put a bead of silicone inside the outer section
of the adapter and a bead of Fireplace 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, 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 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
28
supported 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 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"(191mm) dia. for fl ex) hole
is acceptable.
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.
See "Exterior Vent Terminal 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
and the Riser Vent
Dia. 2 & 2a are available. Follow the
same installation procedures as used
for standard Horizontal Termination.
NEVER install the snorkel upside down.

*As specifi ed in CGA B149 Installation Code.
Local codes or regulations may require different
clearances.
Diagram 2a
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 Snorkel Installation instructions for
details. 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"
clearances to combustible materials are
maintained (Dia. 3.. Install the termination
cap. AstroCap
Horizontal Termination Caps may be used.
The four wood screws provided should
be replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
as shown in
sidings.
Note: If installing termination on a siding
covered wall, a vinyl siding standoff
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
Wall Thimble (Part # 620-926. over the vent
pipe.
