5. Starting at the jamb, place the starter sill 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. Refer to the approved shop drawings for type, size, and specific anchor
details. Shim the starter sill to the proper elevation height making sure the starter sill is level. The shims used must be full bearing shims. The shims must
fully support the entire load bearing surface of the starter sill at each anchor location. Refer to the project structural calculation package and final approved
shop drawings for detailed information.
6. EFCO recommends minimum of a 1/2” caulk joint between the starter sill and the condition.
7. When applying anchor bolts to the starter sill, pre-fabricated serrated washers (17D3) must be used. The serrated washers will lock the starter sill into
position when the anchor bolt is tightened. See Figures 7, 8 and 9. After verifying the final position of the starter sill, secure the anchor bolts as required.
8. 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.
