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, page 21). 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.
