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, cut and fold
flashing as needed to fit chimney (Figure 5.26).

4. To determine the length of flex needed, measure from
3 in. (76 mm) above the top of the flashing down to the
level of the opening. Add the distance from the center
of the chimney out through the wall. Cut a piece of 4
in. (102 mm) flex to this length (extended to its nominal
length). Be sure to leave 2-3 in. (51-76 mm) of flex
above the existing chimney to allow for connection to the
termination kit.
5. Connect the flex liner to the top adapter using four sheet
metal screws (Figure 5.21).
6. Feed the flex liner through the flashing into the chimney.
Carefully feed the flex liner down the chimney to the
bottom and out the opening in the masonry wall, forming
an angle to line up the flex liner with the vent opening on
the appliance.
!
Fire Risk.
Explosion Risk.
• Do not let the flex liner sag below the level
at which it will connect to the appliance or
connector. This could allow hot gas to become
trapped and potentially become a fire hazard.
The flex liner path should always be sloped up
toward the termination cap.
7. If additional lengths of flex liner are needed to span the
chimney height, use a flex coupler to connect the pieces
of flex liner together. Connect the flex to the coupler
by using four sheet metal screws for each side (Figure
5.27).

8. Secure the top adapter to the flashing. Use three sheet
metal screws through the side of the top adapter into the
flange on the flashing (Figure 5.28). Twist lock the high
wind termination cap on to the top adapter.
