These maintenance instructions are for the use of
qualied service personnel only. Service by other than
qualied personnel may result in damage to the oven
and/or injury to the operator.
Qualied service personnel are those individuals, rms,
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 require assistance in the selection of a qualied

Quite often malfunctions, which are attributed to defects,
may be repaired by adjusting certain parts rather than
replacing them.

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
nd 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.

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 mounted to the door’s hinge pin
with a setscrew.
• Open the doors fully.
• Remove the lower cover by loosening the four
screws located inside the door opening.
• Position the doors so they are nearly closed but
not latched.
• To adjust the cam loosen the setscrew and rotate
the cam until you hear the switch click.
• Tighten the setscrew in the cam. Test the door to
make certain the switch will make contact with the
doors closed.
• Replace the combustion cover.
