UNPACKING

Receiving the Griddle

Upon receipt, check for freight damage, both visible and concealed.

Visible damage should be noted on the freight bill at the time of delivery and signed by the carrier’s agent. Concealed loss or damage means it does not become apparent until the merchandise has been unpacked. If concealed loss or damage is discovered upon unpacking, make a written request for inspection by the carrier’s agent within 15 days of delivery. All packing material should be kept for inspection. DO NOT return damaged merchandise to Lang Manufacturing. File your claim with the carrier.

Location

Prior to un-crating, move the griddle as near to its intended location as practical. The crating will help protect the unit from the physical damage normally associated with moving it through hallways and doorways.

Un-crating

The griddle will arrive completely assembled inside a wood frame and strapped to a skid.

Cut the straps and remove the wood frame.

The griddle can now be removed from the skid.

CAUTION

THE UNIT IS EXTREMELY HEAVY. FOR SAFE HANDLING, INSTALLER SHOULD

OBTAIN HELP AS NEEDED, OR EMPLOY APPROPRIATE MATERIALS HANDLING

EQUIPMENT (SUCH AS A FORKLIFT, DOLLY, OR PALLET JACK)

TO REMOVE THE UNIT FROM THE SKID AND MOVE IT TO THE PLACE OF

INSTALLATION.

ANY STAND, COUNTER OR OTHER DEVICE ON WHICH GRIDDLE WILL BE

LOCATED MUST BE DESIGNED TO SUPPORT THE WEIGHT OF THE GRIDDLE.

SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT.

LEG INSTALLATION

The legs are installed by sliding the threaded ends of the legs into the leg receiver tubes located in each corner of the griddle.

Slide the leg up until contact is made with the threaded nut at the top of the reciever tube. Screw the leg counterclockwise until it is hand tight.

After the griddle is in its final position, adjust the legs to create 1/8 inch slant from back to front. This will allow the grease to run into the front grease gutter and provide the proper combustion air for the burners. It will also allow exposed gasses to escape out the rear of the unit.

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.

11

MAINTENANCE & CLEANING

Daily Cleaning (Non chrome only)

• Empty the grease drawer daily or whenever it is 3/4 full. Clean using mild soap and warm water.

• Keep the griddle surface clean. After each cooking load, scrape the griddle surface to remove any carbonized grease.

• Once a day or when necessary the non chrome griddle surface should be thoroughly cleaned and seasoned again. Use a griddle stone, griddle pad, or liquid cleaner. Rub with the grain of the metal, being careful not to scrape the splash guard.

• Following the scraping, a damp cloth and non-silicated, non-abrasive, non-chlorinated cleaner such as Bon-Ami may be used to wipe surface clean, followed by wiping with a clean wet cloth.

Weekly Cleaning (Non chrome only)

• A mild detergent with water or one of the many commercial cleaners may be used.

• Be sure to rinse thoroughly and coat the griddle with a thin film of oil to prevent rusting, non-chrome surfaces only.

• Clean the exterior of the appliance with hot water and a mild detergent to maintain a gleaming appearance.

• Re-season the griddle plate after each cleaning, non-chrome surfaces only.

Burner Air Shutter Adjustment

• The air shutters are pre-set at the factory. However, minor adjustments may be required in the field to accommodate differences in gas and elevation.

• To adjust the air shutters, loosen the set screw holding the air damper to the burner near the gas inlet.

• Adjust the air mixture until the burner flame just flickers on the burner. “Lift-off” or yellow flame indicates improper shutter adjustment.

• Periodically inspect and clean the air shutters to insure complete combustion.

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, nonchlorinated 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

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.

MAINTENANCE & CLEANING continued

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.

ARNING: KEEP WATER AND SOLUTIONS OUT OF CONTROLS. NEVER SPRAY

OR HOSE CONTROL CONSOLE, ELECTRICAL CONNECTIONS, ETC.

WARNING

CAUTION

MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS

MEMBRANES AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN

TO WEAR RUBBER GLOVES, GOGGLES OR FACE SHIELD AND

PROTECTIVE CLOTHING. CAREFULLY READ THE WARNING AND

FOLLOW THE DIRECTIONS ON THE LABEL OF THE CLEANER TO

BE USED.

NOTICE: Never leave a chlorine sanitizer in contact with stainless steel surfaces longer than 10 minutes. Longer contact can cause corrosion.

Calibration

• Set the temperature dials to 350°F (176°C)

• Allow the burners to cycle ON and OFF at least five times before attempting to calibrate

• Place a surface thermometer in the center of each cooking section to be calibrated.

• Allow the burners to cycle several times while recording the temperature at which the burners turn

ON and OFF.

• Average the temperatures together, if the average temperature is within 10° of the set temperature, the thermostat is within specifications and needs no adjustment.

• If the thermostat is out of specification, remove the thermostat knob and inset a small flat blade screw driver down the stem of the thermostat and turn the adjusting screw at the base of the stem.

• Turning the screw counter-clockwise raises the griddle temperature while clockwise lowers the temperature.
