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.
Step 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).
Figure 5.27
Step 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.

Attach the flex to the retro connector. Use three sheet metal
screws to attach the flex liner to the connector (Figure
5.29). Mount the retro connector to the masonry wall using
masonry bolts. Redrill larger holes on connector as needed.
Be careful to ensure that the connector is centered in the
opening and the mounting holes line up with the masonry
wall.

in front of the masonry, use wood screws to mount wall
thimble cover to framed wall, over retro connector and 10
in. (254mm) square framed opening (Figure 5.25, page
