SEQUENCE OF OPERATION
Power On
When the griddle is connected to 115 Volt power, the spark module for each section starts sparking.
While they are sparking the solenoid valve for the pilot burners are energized.
When the individual pilot burners ignite, and the pilot flame is verified, the spark module will stop
sparking. Note: The pilot burners will remain lit until the griddle is removed from power or the gas is
shut off.
When the main switch is turned on, 24 Volts is applied to the temperature control circuit.
When one of the individual section's switch is turned on, it provides power to the circuit board for that
section.
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 circuit
board will generate a "Heat call". This call (24 VAC Signal) goes to the solenoid valve opening the
valve. The pilot burner ignites the main burner.
As the griddle section temperature increases the temperature sense probe resistance increases.
When the griddle section reaches the temperature set on the selector switch, the circuit board which
monitors the probe resistance will turn off the heat call and there by close the gas valve.
When the griddle temperature drops below the set temperature the circuit board generates a new
heat call and the sequence repeats.
MAINTENANCE & CLEANING
Griddle Care (Chromium Surfaces)
It takes very little time and effort to keep this Industrial Chromium griddle surface sparkling clean and
performing at top efficiency. DO NOT allow grease to accumulate as it will carbonize and become
difficult to remove. To prevent this condition the following cleaning suggestions should be followed:
1. Remove excess grease and food regularly with a 4" (100mm) wide Razor Sharp type scraper
and wipe surface with a damp cloth if desired.
2. Following the scraping, for end of the day cleaning, a damp cloth and a non-silicated,
nonabrasive, non-chlorinated cleaner such as Bon-Ami may be used to wipe surface clean,
followed by wiping with a clean wet cloth.
3. Follow steps 2 and 3 from Griddle Care (Non-Chromium Surfaces) above.
CAUTION
1. Never use pumice, griddle stones, or abrasives on a chromium surface.
2. Never strike a chromium griddle surface with a sharp instrument or spatula edge.
3. Never use steel wool.
4. Never use commercial liquid grill cleaner on the griddle surface.
5. Abusing surface voids the warranty.
CHROME GRIDDLE SURFACE LIMITED WARRANTY EXCLUSIONS
Your Chrome griddle has been designed to give you many years of cooking reliability and requires
minimum maintenance to keep the chrome surface in its original condition. All Chrome griddle
surfaces are warranted for a period of 5 years against manufacturing defects to the original owner
from the date of installation. This limited warranty is void if it is determined by Lang Manufacturing
or one of its authorized representatives that the chrome surface has been misused or abused or
subjected to the following situations:
1. Improperly installed.
2. Incorrect voltage applied to Chrome units allowing the surface to overheat and discolor.
3. The misuse of any instrument or tool which scratches or makes indentations in the surface which
could cause the surface to peel, flake, or chip off.
4. The use of any chemical or abrasive cleaning solution, griddle brick, stone, screen or other
cleaning products which could damage and affect the performance of the chrome surface.
5. The neglect of daily routine maintenance to the chromium surface.
