Matrix Insert Installation and Operation Manual
26 ______________________________________________________________________________
It is important to replace the gasket with another having the same diameter and density to
maintain a good seal
.
Remove the door and place it face-down on something soft like a cushion of rags or a piece of
carpet. Remove the old gasket from the door by pulling and prying it out with an old screw driver.
Then use the screwdriver to scrape the old gasket adhesive from the door gasket groove. Apply a
bead of approximately ¼" (6 mm) of high temperature silicone in the door gasket groove. Starting
from the middle, hinges side, press the gasket into the groove. The gasket must not be stretched
during installation. Leave about ½" long of gasket when cutting and press the end into the groove.
Tuck any loose fibers under the gasket and into the silicone. Close the door. Do not use the insert
for 24 hours.

REPLACING THE GLASS OR THE GLASS GASKET
It is a good idea to replace the glass gasket when the door gasket is replaced. The gasket is flat,
adhesive-backed, woven fiberglass. Remove the glass retaining screws (A) and clips (B) then both
metal frames (C) that holds the glass to the door frame (E). Lift out the glass (D) and pull off the
old gasket. This is a good time to clean the glass thoroughly.
The two main causes of broken glass
door are uneven placement in the door and over-tightening the retaining screws.
