WV410 WINDOW - INSTALLATION INSTRUCTIONS

Section VI – SSG WV410 Vent Glazing

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 7. Adjust the blocks as required to keep

the vent square.

Step 8

Insert backer rod material between the glass and the vent material around the entire perimeter

except at setting block locations. The backer rod needs to be recessed far enough to leave the

end of the outer glass lite exposed. See figure 8.

Step 9

Mask off the outside edges of the glass and vent to minimize cleanup and provide a professional

appearance. Fill the void between the glass and the vent with structural sealant. Tool in sealant

and remove the masking tape before a skin begins to form. See Figure 8.

An overnight setup is required to allow the silicone to partially cure before movement of the unit.
