between the Gasket and Door Jamb of a properly adjusted Door. Test the fit at regular 2" to
3" intervals around the entire Door.
1.
If you feel NO resistance at a
particular spot the Door is too loose,
you have found a weak or damaged
spot in the Door Gasket or the Door
Jamb has been bent in.
2.
If you feel HEAVY resistance at a
particular spot the Door is too tight or
the Door Jamb has been bent out.
DOOR GASKET, How To Replace:
Follow these instructions to correctly and easily
replace your Door Gasket with minimal problems. If
you have any problems or questions please call the NU-VU
Monday through Friday from 7:00 a.m. until 5:00 p.m. for assistance.
IMPORTANT: DO NOT DISASSEMBLE THE DOOR FRAME WHEN REPAIRING OR
Replacing the Oven Door Gasket - -
A. Remove all pieces of the old Gasket. Thoroughly clean the Door frame in the area of the new
gasket installation. Remove any old sealant and any baked-on deposits.
B.
Replacement Gasket for the Oven Door is supplied to you as a single length of high-temperature
material. This Gasket must be cut to lengths that slightly overlap the sides of the Door frame.
C. Put a small amount of soap water into and around the slot that the new Gasket will fit into (a
small trigger spray bottle works well). This step is optional but will help in the installation.
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.
IMPORTANT: DO NOT STRETCH OR PULL ON THE GASKET DURING THE
INSTALLATION PROCESS. THIS WILL LATER CAUSE THE TRIMMED CORNERS TO
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 that one or more
gasket sections are cut too short.
IMPORTANT: MAKE SURE THAT THE GASKET AND DOOR FRAME ARE BOTH
COMPLETELY CLEAN AND DRY BEFORE APPLYING ANY SEALANT!
G. Seal the corner joints after the entire Gasket is properly fitted. Pull the joints apart only enough to
put sealant on all of the cut edges only. Allow the Gasket joint to come together. Smooth out any
