4) Pass the fl ex 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 adaptor and into
the chimney top. Insure that
fact, drilling into the metal on the chimney.
Twist-lock the Termination Cap (Part# 980
or 991) onto the Adaptor. (Diagram 3 and
4).

5) Pull the fl ex pipe down through the ceiling
support box, until it protrudes approximately
3" (76mm). Connect the fl ex 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 fl ex pipe back up into the ceiling
support box, center the Retro Connector, and
attach it to the support box, or decorative
sleeve for double wall solid packed pipe,
with the sheet metal screws (supplied).
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.

Converting a Masonry Chimney
Important: The existing
opening needs to have an area of at least
you are in
a 36 sq. in. to insure proper intake/exhaust
fl ow.
1) Before cutting any holes, assemble the
desired sections of black direct vent pipe
to determine the center of the masonry
penetration.
Diagram 3
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
clearance 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 chimney,
then cut and fold fl ashing as needed to fi t
chimney. Diagram 7.

4) To determine the length of fl ex required,
measure from 3" (76mm) above the top of
the Flashing down to the level of the opening.
Add to this measurement the distance from
the center of the chimney to out through
the wall. Cut a piece of 4" fl ex to this length
(the fl ex should already be extended to its
nominal length).
5) Connect the 4" fl ex liner to the Top Adaptor
(Part # 985K) using 3 sheet metal screws.
Diagram 2.
6) Feed the 4" fl ex liner through the Flashing
into the chimney. Continue to feed the liner
out through the opening in the masonry
wall.
7) Secure the Top Adaptor to the Flashing. Use
3 sheet metal screws through the side of
the adaptor into the fl ange on the Flashing
(diagram 8). Twist lock the Termination Cap
(Part # 980 or 991) on to the Top Adaptor.
Diagram 8
8) Attach the fl ex to the Retro Connector. Use
3 sheet metal screws to attach the fl ex
liner to the Connector. Diagram 9. Mount
the Retro Connector to the masonry wall
using masonry bolts. Re-drill larger holes
on connector as needed. Be careful to
insure that the connector is centered in the
opening and the mounting holes line up with
the masonry wall.
