ADJUSTMENTS
DOOR GASKET COMPRESSION CHECK
The Door Gasket Compression Check may be performed
on all styles of the Proofer Oven doors.
BAKING CENTER
Figure 36. Door Gasket Compression Check
Perform the following procedure to determine
if door adjustments are necessary:
1. Close the door with a dollar bill between the gasket and
the front of the oven. There should be resistance when
the dollar bill is pulled free of the door.
2. Perform this check in several places and readjust the
door if necessary using one or both of the procedures
below.
DOOR GASKET ADJUSTMENTS
To adjust the door on the hinge side, use this procedure:
1. With the door closed, remove the hinge covers and loosen
(don’t remove) the six screws that hold the hinges to
the door.
2. With the screws loosened, the door can be moved in and
out on its frame. Move the door to the desired position.
When adjusting the door's position in and out,
don’t over-compress the gasket. This will cause the door to
bind on the hinge side.
3. Once the door is positioned properly, tighten the screws
and replace the hinge covers.
The door can also be adjusted on the handle side:
1. Loosen, but do not remove, the two screws that hold
the handle in place.
2. Adjust the handle to its proper position.
3. Tighten the screws.
AIR WASH DOOR ADJUSTMENT
Earlier versions of the Proofer Oven used
different door styles; they are not Air Wash doors. There are
old style doors with and without hinges and with and without
door handles. The older styles are upgradeable to the newer
Air Wash style, which has a door handle and two window
panes, the inner of which can be opened for cleaning. The
conversion is compatible with all of the earlier door styles.
Refer to Duke Manufacturing Co. publication 512994 for
further information.
The following procedures apply only to the Air Wash door
style.
Air Wash Door Adjustment – Hinge Side
1. If open, close and latch the door.
2. Remove the Hinge Covers.
