Glass Replacement
The glass on the 680 series is easily replaced by removal of the metal glazing beads.
Glass must be Class II Safety Rated.
1) Start by removing all wedge gaskets between glass and glass beads.
2) Once removed begin removing all glazing beads. Carefully pry the glazing bead from the
door starting with the verticals and ending with the horizontals.
3) Clean debris from the interior of the frame using a cleaning solution making sure to remove
all traces of old sealant (if any).
4) The replacement glass must be ¼” wire or ceramic glass rated for use in the application.
Minimum size of the glass is 1” larger than daylight opening of the sash.
5) Next, add setting blocks in a cross blocking formation to distribute the weight of the glass
toward the hinges. (Important! Not completing this step may affect operation of the
window). Please contact Optimum for instructions should you need assistance.
6) Replace last perimeter glazing bead removed back in original position first. Next, replace
all remaining glazing beads starting with the last bead removed, working backwards. If
used, replace muntins and finally seal the exterior of the frame with glazing sealant.
