WV410 WINDOW - INSTALLATION INSTRUCTIONS
Section V – Captured WV410 Vent Glazing
Step 1
Unlock the cam locks and open the vent to expose the hardware. Remove the vent from the
WV410 frame by removing the screws from the hinges. Be sure to mark the vent to correspond
with the appropriate frame. This will insure that the vent is reinstalled correctly.
Step 2
Lay the vent face up on a flat, smooth working surface. Remove the glass stops from the vent.
Step 3
Make sure that the glazing surfaces of the vent are free from oil and metal shavings. Clean the
glazing surfaces as needed with alcohol. (Do not use glass cleaners).
Step 4
Insert a continuous row of pre-shimmed gasket W174 around the vent perimeter glazing leg.
Insert the gasket beginning at each end of the frame and work toward the middle then work out
any waves toward the ends forming tight joints. Do not stretch the gasket.
Step 5
Run a continuous bead of structural silicone sealant behind the tape as shown in Figure 1.
Step 6
Keeping the glass level and centered within the vent material, lower the glass down into place.
Step 7
Insert two (2) HN91 - 3/16” x 1” x 4” setting blocks on each side of the glass 6” from the corners,
as required, based on the configurations shown in Figure 2 above. Adjust the blocks as required
to keep the vent square.
