“APPROVED” shop drawings.
D.) Install infill; typical edge bite is ½”.
1.) Hold infill above the sill horizontal and load the jamb side into the deep
pocket. Rotate the opposite side of the infill into the shallow pocket, and
position infill into the opening. Set the infill squarely onto the setting blocks
with the exterior face of the infill pushed up against the exterior gasket.
Take care not to roll the exterior gasket out of the race.
2.) Install the interior wedge in short lengths to 3 edges of the infill to hold
temporarily.
3.) Install the glazing bead at the head. NOTE: Seal along the face of the mullion
prior to installation of the glazing bead to provide a weather tight seal. Tool
and clean excess sealant from the exposed surfaces after the bead is
positioned as shown in FIG. 4.
4.) Install the jamb spacers as shown in FIG. 5 on page #15.

Customer / Installer Note:
EFCO setting blocks are
typically 4” in length with
different depths. If the
glazing infill is “NOT BY
EFCO” and glazing sizes are
larger than 40 square feet,
then the glazing details
must be reviewed by the
glazing manufacturer for
proper setting block size.
