Connector to mount directly on the masonry 
and provide clearance to the combustibles. 
Refer to Figure 11.
Step 3.  Secure the Flashing (705C) 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, then cut 
and fold ashing as needed to t chimney. 
See Figure 7.
Step 4. To determine the length of ex 
required, measure from 3” above the top 
of the Flashing down to the level of the 
opening. Add to this measurement the 
distance from the center of the chimney to 
out through the wall. Cut a piece of 4-inch 
ex to this length (the ex should already be 
extended to its nominal length).
Step 5. Connect the 4-inch ex liner to the 
Top Adapter (985K) using (3) sheet metal 
screws. Refer to Figure 2.
Step 6. Feed the 4-inch ex liner through 
the Flashing into the chimney. Continue to 
feed the liner out through the opening in the 
masonry wall. 
Step 7.  Secure the Top Adapter to the 
Flashing. Use (3) sheet metal screws through 
the side of the adapter into the ange on the 
Flashing, as shown in Figure 8. Twist lock the 
Termination Cap (980 or 991) on to the Top 
Adapter.
Step 8. Attach the ex to the Retro 
Connector. Use (3) sheet metal screws to 
attach the ex liner to the Connector. See 
Figure 9. Mount the Retro Connector to the 
masonry wall using masonry bolts. Re-
drill larger holes on connector as needed. 
Be careful to insure that the connector is 
centered in the opening and the mounting 
holes line up with the masonry wall.
