Unit Installation with Horizontal Termination
Install the vent system according to the manufac-
turer'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 fittings are designed with
special twist-lock connections to connect 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 system.
3) Put a bead of Mill-Pac inside the outer section
of the adapter and 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: For best results and optimum perfor-
mance with each approved venting system, it is
highly recommended to apply "Mill-Pac" sealant
(supplied) to every inner pipe connection. Failure
to do so may result in drafting or performance
issues not covered under warranty.
b) Horizontal runs of vent must be 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
flex) 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 fire.
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 as shown in Dia. 2 & 2a are available.
Follow the same installation procedures as
used for standard Horizontal Termination.
NEVER install the snorkel upside down.

*As specified in CGA B149 Installation Code.
Local codes or regulations may require different
clearances.

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-Vent Installation
instructions for details. Do not attempt to enclose
the Snorkel within the wall, or any other type of
enclosure. See Diagram 2b.

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
Dura-Vent Horizontal Termination Cap may be
used.
The four wood screws provided should be
replaced with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
Diagram 3
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.
