11. Inspect the I.G. unit for the vent frame. Any excessive sealant or irregularities at the perimeter should be cleaned and trimmed. Check the glass for damage,
particularly along the glass edges and discard any unacceptable units. The secondary sealant joints of the insulated glass units should be checked for
proper size. The approved shop drawings will indicate the required secondary sealant joint size for the glazing on the general information page. Check the
alignment of each pane making up the I.G. unit to ensure they are within acceptable limits. The I.G. unit overall dimensions should be verified for proper size.
12. Using an approved solvent or cleaner, thoroughly clean the edges of the glazing that will contact the structural silicone and spacer of all oils and
other contaminants. Once the glass has been cleaned, it should be handled with gloves or glass manipulator to avoid contaminating the edges that come
into contact with the structural silicone glazing joint.
13. Set the glazing on the silicone spacer gaskets positioned as shown below. The edge of the glazing is flush with the edge of the vertical sash as shown.
Refer to Figures 173 and 175 below. Ensure the glazing is positioned with the exterior side out, and the bottom of the glazing to the setting blocks. Care
should be exercised to avoid shifting or rolling the spacer gaskets when adjusting the position of the glass.
14. Temporarily insert the HS32 setting blocks between the sill sash fin and glazing to position the glazing to the sill. Remove the blocks after final alignment of
the glazing to apply the structural silicone. See Figure 174.
