Waterford TARA T25 Direct Vent Freestanding Gas Stove
Diagram 9
Diagram 8: The upper half of the flashing is
installed under the roofing material and not
nailed down until the chimney is installed.
This allows for small adjustments.

5) Cut a hole in the roof centred on the small
drilled hole placed in the roof in Step 2. The
hole should be of sufficient size to meet the
minimum requirements for clearance to com-
bustibles of 1-1/4". Slip the flashing under
the shingles (shingles should overlap half
the flashing) as per diagram 8.
DURA-VENT VERTICAL
TERMINATION
Secure the connection between the vent
pipe and the vent cap by attaching the two
sheet metal strips extending from the vent
cap assembly into the outer wall of the vent
pipe. Use the two sheet metal screws
provided to connect the strips to the pipe.
Bend any remaining portion of the sheet
metal strip back towards the vent cap, so
it will be concealed by the decorative wall
thimble cover. See diagram 3.
7) Install wall thimble in the center of the 10"
square and attach with wood screws.
8) Slide the decorative wall thimble up to the
wall surface being careful not to scratch
the paint and attach with screws provided.
Apply decorative brass or chrome trim if
desired. See diagram 4.
Note: Apply
sealant "Mill-Pac"
to inner pipe and
high temp sili-
cone sealant or
"Mill-Pac" to out-
er pipe on every
joint.

1) Maintain the 1-1/4" clearanc-
es (air spaces) to combus-
tibles when passing through
ceilings, walls, roofs, enclo-
sures, attic rafter, or other
nearby combustible surfac-
es. Do not pack air spaces
with insulation. Check page
16 for the maximum vertical
rise of the venting system
and the maximum horizontal
offset limitations.
2) Set the gas appliance in its
desired location. Drop a plumb
bob down from the ceiling to
the position of the appliance
flue exit, and mark the loca-
tion where the vent will pen-
etrate the ceiling. Drill a
small hole at his point. Next,
drop a plumb bob from the
roof to the hole previously
drilled in the ceiling, and
mark the spot where the
vent will penetrate the
roof. Determine if ceiling
joists, roof rafters or other
framing will obstruct the vent-
ing system. You may wish to relocate the
appliance or to offset, as shown in diagram
6 to avoid cutting load bearing members.
4) Assemble the desired lengths of black pipe
and elbows necessary to reach from the
appliance adapter up though the Round
Support Box. Insure that all pipes and
elbow connections are in the fully twist-
locked position and sealed.
3) To install the Round Support Box/Wall Thim-
ble in a flat ceiling, cut a 10 inch square hole
in the ceiling centred on the hole drilled in
Step 2. Frame the hole as shown in diagram
7.
6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is impor-
tant to support the vent pipe every
3 feet, to avoid excessive stress
on the elbows, and possible sep-
aration. Wall straps are available
for this purpose. See diagram 4.
Galvanized pipe and elbows may be utilized
in the attic as well as above the roofline. The
galvanized finish is desirable above the
roofline due to its higher corrosion resist-
ance.
Continue to add pipe sections through the
flashing until the height of the vent cap
meets the minimum height requirements
specified in diagram 9 or local codes. Note
that for steep roof pitches, the vertical
height must be increased. A poor draft, or
down drafting can result from high wind
conditions near big trees or adjoining roof
lines, in these cases, increasing the vent
height may solve the problem.
7) Ensure vent is vertical and secure the base
of the flashing to the roof with roofing rails,
slide storm collar over the pipe section and
seal with a mastic.
8) Install the vertical termination cap by twist
locking it.
Notes:
a) For multistorey vertical installations,
a Ceiling Fire stop (Part # 963) is
required at the second floor, and
any subsequent floor. Diagram 10.
The opening should be framed to 10
" x 10" inside dimensions, in the
same manner as shown in diagram
7.
