D. Cleaning of the Ovens
The stainless steel on your oven can be kept clean with a
good stainless steel cleaner, many of which are on the
market. The painted surfaces should be wiped clean
regularly with a MILD detergent. Moisten a cloth and
wipe down the oven while it is COLD. Wiping down an
oven while it is hot will cause streaking and otherwise
unsatisfactory results. Once the oven is clean it can be
wiped down with light oil.
Porcelain oven interiors should be cleaned regularly using
a degreasing agent. For heavier deposits a commercial
oven cleaner such as Dow Oven Cleaner, Easy-Off, or
Mr. Muscle can be used. Care must be taken to prevent
these alkaline-type cleaners from coming in contact with
any aluminized steel surfaces in the oven, including the
blower wheel.
The blower wheel, racks and rack supports can be
removed and soaked in a solution of ammonia and water.
WARNING: Disconnect the power supply to the
appliance before removing blower wheel.
Make certain that all parts are thoroughly rinsed before
returning to use.
MAINTENANCE INSTRUCTIONS
WARNING: Disconnect the power supply to the
appliance before servicing.
WARNING: Units provided with casters have a
restraint to limit the movement of the oven. If this
restraint is disconnected during servicing it must be
reconnected after the appliance has been returned to
its original installed position.
Note: Proper clearances must be maintained during
servicing.
These maintenance instructions are for the use of qualified
service personnel only. Service by other than qualified
personnel may result in damage to the oven and/or injury to
the operator.
Qualified service personnel are those individuals, firms,
companies or corporations which either in person or through
an agent are engaged in and responsible for repair or
servicing of commercial food preparation equipment, who
are experienced in such work, familiar with all precautions
required, and have complied with all requirements of state
and local authorities having jurisdiction.
If you should require assistance in the selection of a qualified
service agency, please contact Duke Manufacturing Co.'s
Service Department at 800-735-3853.
A. Adjustments
Quite often malfunctions, which are attributed to defects,
may be repaired by adjusting certain parts rather than
replacing them.
B. Door Adjustment
6/13 Series Convection Ovens (except model option Q) have
doors that are inter-connected so they operate simultaneously
by means of a chain and turnbuckle assembly. The doors are
properly adjusted and inspected before the oven leaves the
factory. However, from time to time it may become
necessary to readjust the doors after usage. If you find it
necessary to adjust the doors for proper operation, the chain
and turnbuckle assembly is located behind the panel that is
over the doors. It is best to adjust turnbuckles while the door
is in an unlatched position.
•
Loosen the jam nut on both turnbuckles.
•
Make
adjustments
simultaneously
to
both
turnbuckles.
•
Loosening or tightening the assembly will not allow
the doors to work properly. Ideally, you should
loosen one turnbuckle and tighten the other. Some
experimentation will indicate which direction you
will want to make your adjustments.
•
Once the doors are operating properly, retighten the
jam nuts so the unit will stay in adjustment. Test the
door to make certain it is in adjustment.
•
Replace cover.
C. Door Switch Adjustment
You may also wish to adjust the door switch. The door switch
is located behind the combustion compartment cover, on the
right side. The door switch is activated by a cam, which is
Blower Wheel
