WARNING

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 5.28).

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 5.29). 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 5.30). 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 the wall thimble cover over retro connector and secure with masonry bolts (Figure 5.31). 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 5.26, page 20). 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.
