Series 526 Impact Installation Instructions
SECTION V: Door Frame Installation
Step 1) General Notes
Step 2) Subsill Installation at Door Opening
Door frames should be installed first, before all other framing material. 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.
The door frame module is shear block only. All sidelites will be screw spline application.
Door jambs do not set on the subsill. Door jambs must run through to the floor condition.
INSTALL 1ST
Where a door opening is required, use the equation in figure 1 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 7-22 on pages 24
through 30. End dams are not required at the door frame end of the subsill. The subsill
should butt up tight to the door frame.
