MAINTENANCE
WARNING: ELECTRIC POWER ALWAYS SHOULD BE SHUT OFF BEFORE WORK IS DONE
ON INTERNAL COMPONENTS.
WARNING: DISCONNECT ELECTRICAL POWER FROM THE UNIT BEFORE ATTEMPTING
TO GREASE THE TRUNNION BEARINGS.
Your braising pan is designed to require minimum maintenance, but certain parts
may need replacement after prolonged use. After installation, no user adjustment
should be necessary. If a service need arises, only authorized personnel should
perform the work.
Service personnel should check the unit at least once a year. This periodic
maintenance should include inspecting electrical wires and connections, cleaning
the inside of the control console, and possible adjustment of the pilot light. (Units
with standing pilot ignition only) At least twice a year, grease the two trunnion
bearings and worm gear.
We recommend the use of number two grade LGI lithium grease. Add grease
through the zerk fittings on the gear hosing until grease flows out of the bearings
around trunnion shaft. Also, add grease in the gear to cover arc that is in contact
with the worm gear. Clean up excess grease.
A Service Log is provided with the warranty information at the back of this manual.
Each time service is performed on your equipment, enter the date on which
the work was done, what was done, and who did it. Keep the manual with the
equipment for quick and easy reference.
SAFETY PRECAUTIONS
A stop-cock will be fitted in the gas pipe supplying the appliance. The user must
be familiar with its location and operation, and able to turn it off in an emergency.
If there is a smell of gas, immediately turn off the gas, ventilate the area, and call
the gas supplier.
NEVER USE NAKED FLAME TO SEARCH FOR GAS LEAKS.
REPLACEMENT PARTS
To order parts, contact your Authorized Service Agent. Supply the model
designation, serial number, part description, part number, quantity, and when
applicable, voltage and phase.

TROUBLESHOOTING
This unit is designed to operate smoothly and efficiently if properly maintained.
However, the following is a list of checks to make in the event of a problem.
Wiring diagrams are found at the end of this manual. When in doubt, turn unit
off and call for service at 888-994-7636. If an item on the check list is marked

WARNING: ELECTRICAL POWER MUST BE SHUT OFF BEFORE WORK IS DONE ON INTERNAL
COMPONENTS. USE OF ANY REPLACEMENT PARTS OTHER THAN THOSE
SUPPLIED BY THE MANUFACTURER OR THEIR AUTHORIZED DISTRIBUTOR
CAN CAUSE INJURY TO THE OPERATOR AND DAMAGE TO THE EQUIPMENT
AND WILL VOID ALL WARRANTIES. SERVICE PERFORMED BY OTHER THAN
FACTORY-AUTHORIZED PERSONNEL WILL VOID ALL WARRANTIES.
