With the pipe attached to the stove, slide the
stove into its correct location, and mark the
wall for a 241mm x 241mm (inside dimen-
sions) square hole. The center of the square
hole should line up with the centerline of
the horizontal pipe, as shown in diagram
3. Cut and frame the 241mm square hole
in the exterior wall where the fl ue will be
terminated. If the wall being penetrated is
constructed of non-combustible material,
i.e. masonry block or concrete, a 178mm
diameter hole is acceptable.

Direct Vent pipe and fi ttings
are designed with special
twist-lock connections to
connect the fl ueing sys-
tem to the appliance fl ue
outlet. A twist-lock appli-
ance adapter is installed
on the unit at the factory.
Assemble the
desired combi-
nation of pipe

You will require the following components with
your new Direct Vent Freestanding Gas Stove.
Please review your product to make sure you
have everything you need. In the event that you
are missing any part, contact your dealer.
Note: These are the minimum pieces re-
quired. Other parts may be required
for your particular installation. See
above for a list of fl ue parts.
If installing termination on a siding covered wall,
a vinyl siding standoff or furring strips can be
used in order to ensure that the termination is
not recessed into siding.
The vinyl siding standoff is required for walls
with vinyl siding.
Minimum components for a Dura-Vent
Horizontal Installation:
A) Dura-Vent Horizontal Termination Kit
B) Wall Thimble (required for combustible
walls)
Minimum components for a Dura-Vent
Vertical Termination:
D) Dura-Vent Vertical Termination Kit. See
above for pipe lengths.
adapter with pipe seams oriented towards
the wall or ceiling, as much out of view as
possible. The fi nal positioning of the pipe
and 90
o
elbow assembly is determined by
the mounting orientation of the adapter on
the stove and twist-locked for a solid con-
nection.
Note:
a)
Twist-lock procedure: Four indentations,
located on the female ends of pipes and
fi ttings, are designed to slide straight
onto the male ends of adjacent pipes
and fi ttings, 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 fi ttings. They may be
located by examining the inside of the
female ends. Apply sealant "Mill-Pac" to
inner pipe and high temp silicone sealant
to outer pipe on every twist-lock joint.
