3. When re-glazing an opening or openings at a captured unit follow these instructions:
a. Carefully insert new setting blocks in the locations as noted in the approved shop drawings.
b. Clean the new glass or panel and set it in place, centered in the opening, setting on the setting blocks. Do not contaminate the sealant contact
surfaces of the glazing during handling. Press the glazing firmly against the spacer gaskets. Avoid sliding the glazing around on the spacers, as this
can force sealant into visible areas seen from the interior. See Figures 137 and 139.
c. Apply temporary retainers with wedge gaskets (WC22) at quarter points of the D.L.O. on all four sides of the opening. See Figures 137 and 139.
d. Tool the sealant around the perimeter of the glazing, packing the sealant into the joint, to ensure any voids or air bubbles in the sealant are
eliminated. Carefully relocate the glazing retainers to expose inaccessible areas behind the retainer, and tool the sealant at those areas. Pay
particular attention at the corners of the glazing. See Figure 138 and 140.
e. Inspect the weep system in the cover and glazing pocket and confirm the weeps slots and holes are intact and unobstructed.
f.
Remove and replace the temporary retainers with a glazing bead and gasket (WC22) jon one side of the glazing at a time. Replace one side, and
then replace the opposing side next. Replace the remaining sides last. If the exterior gaskets were damaged when they were removed, replace
them with new gaskets. See Figure 138 and 140.
