Waterford TARA T25 Direct Vent Freestanding Gas Stove 19
b) Horizontal runs of vent must be sup-
ported 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. 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-combus-
tible material, i.e. masonry block or con-
crete, 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. Nev-
er 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 Ter-
minal Locations, see diagram on
page 10.
4) If installing the vent termination to a wall
with vinyl siding, the Vinyl Siding Standoff
must be used. Attach the Vinyl Siding
DURA-VENT
HORIZONTAL
INSTALLATIONS
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 con-
nect the venting system to the appliance
flue outlet. A twist-lock appliance adapter
is installed on the unit at the factory. Assem-
ble the desired combination
of pipe and elbows to the
appliance adapter with pipe
seams oriented towards the
wall or ceiling, as much
out of view as possible.
The final positioning of
the pipe and 90
o elbow
assembly is determined
by the mounting orienta-
tion of the adapter on
the stove and twist-
l o c k e d
for a sol-
id con-
nection.

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 ori-
enting the four pipe indentations so
they match and slide in to the four
entry slots on the male ends (dia-
gram 1). Push the pipe sections com-
pletely together, then twist-lock one
section clockwise approximately
one-quarter turn, until the two sec-
tions 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. Apply sealant "Mill-Pac" to in-
ner pipe and high temp silicone seal-
ant to outer pipe on every twist-lock
joint.
Hint: Apply
silicone to
f e m a l e
end.

Standoff to the Horizontal Vent Termination,
but first run a bead of non-hardening mastic
around its outside edges, so as to make a
seal between vent cap and the standoff.
Install the Vinyl Siding Standoff (Part # 950)
between the vent cap and the exterior wall
and attach with the four wood screws
provided. Seal around the Vinyl Siding Stand-
off on all four sides. Diagram 2. The arrow
on the vent cap should be pointing up.
Insure that the 1-1/4" clearances to com-
bustible materials are maintained. See dia-
gram 2. VENT RESTRICTOR
The above Offset to Vertical Installation re-
quires more restriction, the Vent Restrictor must
be set to 5/8" (16mm).
The Vent Restrictor on the stove comes preset
with a 7/8" (22mm) opening. The Vent Restrictor
is located inside the firebox over the flue outlet.
To adjust the restrictor simply use a large phillips
screwdriver to loosen the 2 retaining screws
and slide the restrictor up to a 5/8" gap. Tighten
the screws to secure it in position.
INSTALLATION
Note: If installing termination on a siding
covered wall, a vinyl siding stand-
off or furring strips must be used
to ensure that the termination is
not recessed into the siding. The
f o u r w o o d s c r e w s p r o v i d e d
should be replaced with appropri-
ate fasteners for stucco, brick,
concrete, or other types of sid-
ings.
5) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
black decorative wall thimble cover over
the vent pipe, then slide the Wall Thimble
(Part # 942) over the vent pipe.
6) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
pipe into the vent cap assembly. It is impor-
tant that the vent pipe extends into the vent
cap a sufficient distance so as to result in
a minimum pipe overlap of 1-1/4 inches.
