1. Clean the sealant contact surfaces on the underside of the gutter (Figure 40) and the top of the jamb (Figure 41) using an approved solvent or
cleaner. Apply a heavy bed of sealant to the underside of the gutter and onto the mullion stack leg of the assembled mullion as shown in Figure 40.
2. Apply a heavy bead of sealant to the jamb as shown in Figure 41.
3. Tilting the jamb at an angle as shown in Figures 41 and 42, mate the jamb and unit mullions beginning at the gutter end and rotating the jamb into place as
shown. Use clamps to snap together the jamb to the unit mullion. Light tapping with a glazing hammer will aid in snapping the mullions.
4. Secure the jamb mullion to the unit with SFQ5 fasteners into the 8806 spacers. Tool the sealant smooth as shown in Figure 43.
