1. Using an approved solvent or cleaner, clean the frame gasket contact surfaces of all oils and other contaminants.
2. Remove the liner from the frame gaskets and apply them to the matching surfaces of the mullions ensuring the holes and edges align as required. See
Figure 2, 3, 4, page 17. Butt sealing the ends of the horizontals may be used instead of applying frame gaskets, if desired.
3. Smooth out the frame gaskets onto the mullion surfaces by forcing out any remaining air bubbles.
4. Assemble the outside glazed framing members as shown below. Additional support for frames with the filler as a vertical on both sides may be needed
depending on the overall frame size. See the note on page 17 for special sealant requirements at perimeter jamb, filler and horizontal intersections.
5. Carefully trim away excess gasket material around the exposed areas if required.
