22 Waterford TARA T25 Direct Vent Freestanding Gas Stove
Converting a Masonry Chimney
Important: The existing masonry flue
opening needs to have an area of at least
a 36 sq. in. to insure proper intake/ex-
haust flow.
1) Before cutting any holes, assemble the
desired sections of black direct vent pipe to
determine the center of the masonry pene-
tration.
Diagram 6
2) Once the center point of the penetration has
been determined, cut a 6" (152mm) dia. hole
in the masonry. Be careful, if the hole is too
large, the Retro Connector might not mount
properly, and if the hole is too small, then the
appliance might starve for intake air. If there
is a frame wall in front of the masonry wall,
cut and frame a 10" (254mm) clear square
opening in the wall (centered around the 6"
(152mm) masonry opening). IF there is
sheet rock only (no studs) in front of the
masonry, the 10" (254mm) clear opening is
still needed, but does not need to be framed.
This allows the Retro Connector to mount
directly on the masonry and provide clear-
ance to the combustibles. Diagram 11.
3) Secure the Flashing (Part # 705C) to the top
of the masonry chimney using a bead of
non-hardening sealant-adhesive. If the
Flashing is larger than the top of the chim-
ney, then cut and fold flashing as needed
to fit chimney. Diagram 7.

4) Pass the flex pipe down through the center
of the chimney system, and center the
adaptor on the top of the chimney pipe. Drill
four 1/8" diameter holes through the adap-
tor and into the chimney top. Insure that you
are in fact, drilling into the metal on the
chimney. Twist-lock the Termination Cap
(Part# 980 or 991) onto the Adaptor. (Dia-
gram 3 and 4).
5) Pull the flex pipe down through the ceiling
support box, until it protrudes approximate-
ly 3" (76mm). Connect the flex pipe to the
Retro Connector by slipping it into the
4-3/4" diameter sleeve on the top side of the
Connector. Use 3 sheet metal screws to
assemble these two parts.
6) Push the flex pipe back up into the ceiling
support box, center the Retro Connector,
and attach it to the support box, or decora-
tive sleeve for double wall solid packed
pipe, with the sheet metal screws (sup-
plied). The holes in the Retro Connector are
pre-punched. Diagram 5.
7) The connection between the appliance and
the Retro Connector may be completed
with sections of black direct vent pipe,
together with an adjustable length.
3) Connect the end of the
flex pipe section to the
underside of the Top
Adaptor using 3 sheet
metal screws.

The direct vent system must not be con-
nected to a damaged factory-built or ma-
sonry chimney.
For factory built, zero clearance, and ma-
sonry chimneys cleanout doors and caps
or plugs for cleanout tee fittings and ash
dumps shall be secured in place and
sealed before installing a Direct Vent
system within the chimney.
If the appliance shuts off during opera-
tion, contact a qualified service person to
determine if a negative pressure and/or
leaky chimney condition exists. Do not
operate the appliance until the problem
is corrected.
Approved for US Installations Only
The use of an existing chimney as an air
intake is not covered under the ANSI
Z21.88b-1999, CSA 2.33b-M99 test meth-
ods and the resulting ITS/WHI product
certification. The code Authority Having
Jurisdiction must be consulted prior to
proceeding with this installation method.
Converting a Factory Built
Metal Chimney
1) Remove the existing chimney cap.
2) Measure the distance from the top end of
the chimney to the bottom of the ceiling
support box, add 3" (76mm) to this meas-
urement, and cut a section of the 4" flex pipe
to that length (the flex should already be
extended to its nominal length).
