14. Using an approved solvent or cleaner, clean the surfaces of the mullions at the intersection of the intermediate horizontal and vertical.
15. Apply a heavy bead of sealant at the intersection of the intermediate horizontal and vertical (See Figure 32). The sealant should run between the structural
seals of the adjacent lites and extend from the edge of the vertical over to below where the intermediate horizontal adapter will be set.
16. Roll the 17H6 SSG glazing adapter into the isolator at the horizontal as shown in Figure 33. This must be done immediately after step 14 and 15 above,
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.
17. 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.
