Unit Installation With Hori-
zontal 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 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.
Notes:
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, 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.

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.
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) dia. (7-1/2"(191mm)
dia. for flex) hole is acceptable.
Note: With Dura-Vent, the minimum height is
achieved by installing a 90
o
the rigid pipe adaptor.
Notes:
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 Exterior Vent
Termination Location.
c) Snorkel Terminations:
For installations requiring a vertical rise on
the exterior of the building, 14-inch and 36-
inch tall Snorkel Terminations are available,
as well as the standard Riser Vent. Follow
the same installation procedures as used
for standard Horizontal Termination. NEVER
install the snorkel upside down.

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.
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.
