DURA-VENT HORIZONTAL
TERMINATIONS
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 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 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 indenta-
tions, 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, 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 fittings. They may be
located by examining the inside of the
female ends.
Diagram 1
NOTE: For best results and optimum perfor-
mance with each approved venting system, it is
highly recommended to apply "Mill-Pac" seal-
ant (supplied) to every inner pipe connection.
Failure to do so may result in drafting or per-
formance 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 ex-
terior 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) dia. (when
using ridid pipe) hole is acceptable.
Note: With Dura-Vent,
the minimum height is
achieved by installing
a
9 0

o
directly to the
flue adaptor.
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 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.
For External Vent Terminal Locations,
see the "Exterior Vent Termination
Locations" section.

Note: Riser Vent
is only for use
in above grade
terminations.

*Diagrams 3 & 4: As specified in CGA B149
Installation Code. Local codes or regulations
may require different clearances.
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.

6) The arrow on the vent cap should be
pointing up. Insure that the 1-1/2" clearances to
combustible materials are maintained (Diagram
4). Install the termination cap.
