jambs must run through to the floor condition.
INSTALL 1ST
Where a door opening is required, use the equation in figure 12 above. Install the
door frame true and plumb in the opening as specified on the shop drawings or
architectural drawings. Install the subsill in the same manner as illustrated in
figures 21-30 on pages 20 through 24. End dams are not required at the door
frame end of the subsill. The subsill should butt up tight to the door frame. See
figure 13 on page 16 for subsill sealant requirements at the door framing.
Door frames should be installed first, before all other framing material, when
required. The system subsill must be installed from the door framing, ensuring that
the appropriate clearance is available for the door frame. All subsequent modules
must be installed from the door jambs outward. Because of shear block
construction methods used with the door framing, the immediate side lites must be
shear blocked to the door jambs. From this point, either shear block or screw
spline construction methods may be used on the remainder of the framing.
