10. Slide WC20 bulb gasket into 17A6 SSG vertical fin bar. Exercise care to avoid stretching the gasket during installation. Let the bulb gasket run approximately
1/4” longer than 17A6. The bulb gasket must be installed prior to applying 17A6.
11. Crimp the bulb in place to prevent slippage during unit installation. Crimp at each end of the adapter, and 24” on center.
12. Roll the 17A6 SSG vertical fin bar into the isolator in each vertical mullion of the assembled unit (See Figures 27 and 28). Crowd the bulb gasket so it is flush
with each end of the fin bar during fin bar installation. The fin bar runs between the gutter and the stack sill glazing adapter with approximately 1/8” gaps at
each end for sealant continuity.
13. Adjust the 17B7 stack sill adapter so that it is flush with the 17A6 vertical fin bar on each end as shown in Figure 29.
