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 masonry fl ue open-
ing needs to have an area of at least 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 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 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

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 open-
ing. 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
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
on to the Top Adaptor.
8) Attach the fl ex to the Retro Connector. Use
Diagram 8
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 con-
nector as needed. Be careful to insure that
the connector is centered in the opening and
the mounting holes line up with the masonry
wall.

9) Slide the Wall Thimble Cover over the Retro
Connector and secure with masonry bolts.
Diagram 10. If you have a framed wall in
front of the masonry, use wood screws to
mount the Wall Thimble Cover to the framed
wall, over the Retro Connector and the 10"
(254mm) square framed opening. Diagram
11. If needed, add a section of direct vent
pipe to the Retro Connector in order to extend
through the opening in the Wall Thimble
Cover.
