3.3 Repeat steps 3.2 until all glass is set, working row by row up the elevation.

a. Prior to installing vertical pressure plates, apply sealant to the face of each horizontal zone plug. See

Figure 3.3a. Vertical pressure plates must be installed before the horizontal pressure plates are applied.

b. FS-325 pressure plate fasteners must be located 1 1/2" from horizontal/vertical mullion intersections

in order to maintain proper compression on the glass. Drill 7/32" holes in pressure plates as required.

PRESSURE PLATE SEALING

c. After removing vertical temporary retainers, install vertical pressure plates with FS-325 screws, holding

back 1/8" from the ends of the vertical mullion.

d. After removing horizontal temporary retainers, center horizontal pressure plates in opening, leaving 1/8"

gap on each end. Make sure that weep holes are on the top side of the pressure plate. NOTE:

Horizontal pressure plates and face covers run continuous over SSG mullions, not to exceed 3 lites in

length. See Figure 3.4 for splicing and sealing instructions.

Existing seal

Note:

Just prior to installing vertical pressure plates,

fill gap between zone plug and isolator & apply Dow Corning 795

sealant to face of zone plug.
