Step 3
Place the WV410 frame into position keeping the 1/32” offset from the interior face of the
storefront to the interior face of the WV410 frame. Place HN91 shims at the mounting screw
location and clamp the WV410 frame into place. Using the WV410 frame as a guide, drill .159”
diameter (No. 21 drill) holes into the storefront frame. Secure the vent with SFP1 screws.
Step 4
Prior to installing the window, refer to Step 8 on page 14 for the required sealing locations. If
casement vents are used, see Section VIII for lift block installation. If projected windows are
used, continue to Step 5 for vent installation.

Reinstall the vent into the WV410 frame. Be sure to mount the hinge to the same location as
preinstalled by EFCO. See Section IX on page 20.
