Dura-Vent
Horizontal Terminations
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.
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 installed on
the unit at the factory. Assemble the desired
combination of pipe and elbows to the appliance
adaptor with pipe seams oriented towards the
wall or ceiling, as much out of view as possible.
The final positioning of the pipe and 90
assembly is determined by the mounting
orientation of the adaptor on the stove and
twist-locked 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 (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 vent-
ing system, it is highly recommended
elbow
o
to apply "Mill-Pac" sealant (supplied)
to every inner pipe connection. Fail-
ure 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.
3. With the pipe attached to the stove, slide the
stove into its correct location, and mark the
wall for a 10" x 10" (inside dimensions) square
hole. The center of the square hole should line
up with the centerline of the horizontal pipe, as
shown in diagram 2. 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" diameter hole
is acceptable.

Note:
a) The horizontal run of vent should 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
instructions in the "External 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 as shown in
Dia. 3 are available, as well as the standard
Riser Vent, see Dia. 3a. Follow the same
installation procedures as used for standard
Horizontal Termination. NEVER install the
snorkel upside down.
*Dia 3, 3a & 4: As specified
in CGA B149 Installation
Code. Local codes or
regulations may re-
quire different clear-
ances.

NOTE: For Snorkel terminations in ABOVE
grade installations, follow national or local
code requirements.
