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 V ent 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 adaptor 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) T
wist-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" 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. W all straps are available
for this purpose.
5) Mark the wall for a 10" x 10" square hole. T he
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.
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.
c) Snorkel Terminations:
For installations requiring a vertical rise on
the exterior of the building, 14-inch and 36-
inch tall Snorkel T erminations are available,
as well as the standard Riser Vent. Follow
the same installation procedures as used
for standard Horizontal T ermination. NEVER
install the snorkel upside down.
Note: Riser Vent is
only for use in above
grade terminations.
Diagram 3a
*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.
Diagram 4
NOTE: For Snorkel terminations
ABOVE grade installations,
follow national or local code
requirements.
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.
The four wood screws provided should be
replaced with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
