4. Pass the flex pipe down through the center of the
chimney system, and center the top adapter on the top
of the chimney pipe. Drill four 1/8 in. (3 mm) diameter
holes through the top adapter, and into the chimney
top. Ensure that you are drilling into the metal on the
chimney. Twist lock the high wind termination cap onto
the top adapter (Figures 5.22 and 5.23).
5. Pull the flex pipe down through the ceiling support box,
until it protrudes approximately 3 in. (76 mm). Connect
the flex pipe to the retro connector, and attach with
sheet metal screws.
6. Push the flex pipe back up into the ceiling support box,
center the retro connector, and attach it to the support
box with sheet metal screws.
7. The connection between the appliance and the retro
connector may be completed with sections of direct
vent pipe.
1. Remove existing chimney cap.
2. Measure the distance from the top of the chimney to
the bottom of the ceiling support box, add 3 in. (76
mm) to this measurement, and cut a section of 4 in.
(101 mm) flex pipe to that length (the flex should be
fully extended).
3. Connect the end of the flex pipe section to the
underside of the top adapter, using four sheet metal
screws (Figure 5.21).
