18. Using an approved solvent or cleaner, clean the surfaces of the mullions at the intersection of the intermediate horizontal and the jamb vertical.
19. Apply a heavy bead of sealant at the intersection of the intermediate horizontals and verticals (Refer to Volume 2, page 15, Figure 32 of the S-8000 Unitized
Curtain Wall Assembly Instructions).
20. Roll the 17H6 SSG glazing adapter into the isolator at the horizontal as shown in Figure 16. This must be done immediately after step 14 and 15, page 15 of
Volume 2, before the sealant begins to cure. The adapter should be setting in sealant at the ends while leaving the notched areas free of sealant. The notch
areas at the ends are to be left open and sealant free for use as a weep system for the horizontals.
21. Insert HS32 setting blocks between the glazing adapter and the glass at quarter points, or as directed per the final approved shop drawings. Light prying
pressure may need to be applied to the glazing adapter to insert the setting blocks into place.
