Step 9. Attach the flex to the retro connector.
Use three sheet metal screws to attach
the flex liner to the connector (Figure
27). Mount the retro connector to the
masonry wall using masonry bolts.
Redrill 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.
Step 10. Slide wall thimble cover (SDV #940)
over retro connector and secure with
masonry bolts (Figure 28). 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 (254mm) square
framed opening (Figure 23, page 30). 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.
Step 11. The connection between the appliance
and the retro connector may be
completed with sections of direct vent
pipe.
Step 12. Move the appliance into the desired
location.
