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.

Step 9- 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.

Step 10 - Slide wall thimble cover over retro connector
and secure with masonry bolts (Figure 5.30). If you have
a framed 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). 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.
