Step 1 - Remove existing chimney cap.
Step 2 - Measure the distance from the top of the chimney
to the bottom of the ceiling support box, add 3 in. (76mm) to
this measurement, and cut a section of 4 in. (101mm) flex
pipe to that length (the flex should be fully extended).
Step 3 - Connect the end of the flex pipe section to the
underside of the top adapter, using four sheet metal screws
(Figure 5.21).

Step 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. (3mm) 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).
