D. Position the new Gasket over the slot, allowing the ends to extend past the end of the slot. Press the
mounting flange down into the slot on the Door frame. Use a roller tool to force the mounting flange
into the slot by working the tool back and forth along the Gasket. Make sure the Gasket mounting
flange is completely fitted into the slot and that the Gasket is free to slide back and forth in the slot.
E. Use a sharp knife or a single-edged razor blade to cut the ends of the Gasket at a 45° angle (you can
use the mitered corner joint on the Door as an angle guide). Cut the Gasket about 1/4" longer than
the required length and work the excess back into the slot. This extra Gasket will help to create a nice
tight corner joint, and allows for any follow-up trimming that may be necessary.
F. Work your way around the entire Door (or the section of the Door having the Gasket replaced).
Make sure the Gasket is just
tight into the corners. A bulging joint or pucker along the Gasket
indicates a Gasket section that is cut too long. Joints that pull apart indicate a Gasket section (or
sections) that are cut too short.
G. Seal the corner joints after the entire Gasket is properly fitted. Pull the joints apart only enough to put
sealant on all the cut edges only. Allow the Gasket joint to come together. Smooth out any excess
sealant to form a smooth surface on the face of the Gasket. Add more sealant to any spots as
necessary and smooth them down.
H. A quality sealant will be dry to the touch and tack-free in one to two hours after application.
However, it will not be completely cured until six to eight hours later. We recommend that you wait
until after your sealant is completely cured before using your oven.
IMPORTANT: DO NOT STRETCH OR PULL ON THE GASKET DURING
THE INSTALLATION PROCESS. THIS WILL LATER CAUSE THE
TRIMMED CORNERS TO SEPARATE AND PULL APART!!!
IMPORTANT: MAKE SURE THAT THE GASKET AND DOOR FRAME ARE
COMPLETELY CLEAN AND DRY BEFORE APPLYING ANY SEALANT!!!
WARNING: SOME SEALANTS GIVE OFF ACIDIC FUMES AS THEY CURE.
THESE FUMES MAY CAUSE IRRITATION TO THE EYES AND/OR NASAL
PASSAGES. USE CAUTION WHEN OPENING YOUR UNIT AFTER
WAITING FOR ANY FRESH SEALANT TO SET UP AND CURE!!!
