DOOR LATCH, How To Adjust:
Determine if the Oven Door [41] or Proofer Door [42]
is fitting too loose (it will leak moisture and heated air
past the Gasket) or too tight (it will not close properly,
or will "pop" open unexpectedly). If it is too loose the
Door Latch [44] must be adjusted OUT (away from the
unit); if it is too tight the Door Latch must be adjusted
IN (towards the unit). Please proceed as follows:
A. Loosen the two acorn nuts inside the Latch Cover
[45] with a 3/8" box wrench. Pull the Latch Cover
straight out from the Door to remove it, and then
remove the acorn nuts.
B. Open the Door and take careful notice of the
adjustment plate position against the body of the
Door Latch.
C. Hold the adjustment plate against the body of the
Door Latch with one hand while you loosen the
three mounting screws with the other hand. Back
the screws out approximately three full turns.
D. CAREFULLY move the Door Latch body IN or
OUT under the adjustment plate
one notch at a
time
. Make sure the Door Latch stays straight up and down, and tighten the mounting screws.
Test the Door for proper closing and sealing (refer to the
DOOR TEST PROCEDURE
).
E. Repeat steps "C" and "D" if you are not satisfied with the Door adjustment. If the Door tests as
satisfactory make sure the three mounting screws are tightened securely.
F.
Install the acorn nuts on the ends of the top and bottom Door Latch screws. Turn the nuts on all
the way until they just contact the back side of the latch bracket, then loosen them by 1½ to 2 full
turns. Install the Latch Cover and tighten the acorn nuts lightly to hold the Latch Cover in place.
DOOR TEST PROCEDURE:
A. Cut one or two strips of paper approximately 1" wide and 8" to 10" long.
B. Open the Door slightly, insert a strip of paper between the Gasket [46] and Door Jamb and close
the Door.
C. Slowly pull the paper strip out. You should feel some resistance as you pull the strip from
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.
