Section 4 - Dynamic Starter Sill Preparation and Installation
5. Starting at the jamb, place the starter sill base into the opening hard on the condition in the final position, excluding elevation. Match drill the substrates at
the anchor locations and apply the anchors allowing for shim space under the starter sill base. Refer to the approved shop drawings for type, size, and
specific anchor details. Shim the starter sill base to the proper elevation height. Ensure that the starter sill base is true, level, and plumb.
6. When applying anchor bolts to the starter sill base, pre-fabricated serrated washers (17D3) must be used. The serrated washers will lock the starter sill base
into position when the anchor bolt is tightened. See Figures 25, 26 and 27. After verifying the final position of the starter sill, secure the anchor bolts as
required.
7. Put a temporary shim between the end dam and the condition to protect the end dam during unit installation. The required shim thickness will vary due to
field tolerances and project specific joint size requirements, but a minimum of 1/2” is recommended. Remove the shim after unit installation.
