17. Apply a heavy bead of sealant at the intersection of the intermediate horizontal and vertical (See Figure 83). The sealant should run between the structural
seals of the adjacent lites and the areas that will contact the 17B9 glazing adapter.
18. Clean the ends of 17B9 captured glazing adapter .
19. Apply beads of sealant to each end of 17B9 as shown in Figure 82.
20. Roll the 17B9 captured glazing adapter into the isolator at the horizontal as shown in Figures 84 and 85. This must be done immediately after the steps
above, before the sealant begins to cure.
21. Using a putty knife, thoroughly tool the sealant, blending it into the adjacent surfaces.
22. Insert HS31 setting blocks, (2) per location, 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 (See figures 84 and 85).
