OPERATION
Loading the Griddle
An understanding of how the griddle sections are controlled will be a valuable aid in loading your
griddle.
Each 12 inch section of your griddle is independently controlled. The temperature control sensor is
mounted under the griddle plate in the center of each cooking section.
If the product is loaded directly over the temperature sensor, that section will turn on and the
burner will heat the entire cooking section. If the product is loaded to the side, front or back of the
temperature sensor, the thermostat will react to the temperature change much slowly.
During slow periods with minimal loads, do not load directly over the thermostat sensors as this will
unnecessarily turn the burners on and overheat the remainder of the section not being utilized.
Turn the product and continue cooking until it has reached its desired degree of doneness.
Remove the product from the griddle.
When reloading the griddle, first use the griddle surface on which a previous load was not placed.
This will insure you the proper griddle temperature.
SEQUENCE OF OPERATION
Power On
When the griddle is connected to 115 Volt power, and the switch is turned “ON” the spark module for
each section starts sparking.
When the individual pilot tubes ignite, and the pilot flame is verified, the spark module will stop
sparking. Note: The pilot tubes will remain lit until the griddle is turned “OFF” or the gas is shut off.
The operator can now set the temperature of that section by selecting it on the temperature dial.
When the temperature on the dial is set higher than the temperature of the griddle section the
thermostat will generate a “Heat Call”. If the pilot tube is lit, the call goes to the control opening the
valve. The pilot burner ignites the main burner.
As the griddle section temperature increases the thermostat turn off the heat call, followed by the
close of the gas valve.
When the griddle temperature drops below the set temperature the thermostat generates a new heat
call and the sequence repeats.
