NOTICE

Gas Connection

This griddle is manufactured for use with the type of gas indicted on the data label. If this does not match your gas type contact the factory and a conversion kit can be acquired.

All gas connectors must be in accordance with local codes and comply with the National Fuel Federal Gas Codes ANSI Z223.1 latest edition.

This appliance should be installed with a separate gas valve in the gas line ahead of the unit. Use a 3/4-inch or larger gas supply line.

Remove the 5/16-inch nuts securing the rear of burners. These nuts are for securing the main burners during transportation only. The rear burner shield must be removed to gain access to the nuts.

A pressure regulator for the type of gas specified is supplied with each appliance and is plumbed into the manifold. The pressure in the manifold of the appliance should be tested with a manometer and the regulator adjusted for proper pressure with the appliance operating at full fire. A 1/8-inch NPT tap is provided in the manifold for connecting a manometer.

Correct manifold pressures are:

5 inches water column for natural gas

10 inches water column for propane

When replacing the plug in the manifold, a pipe joint compound or sealant should be used that is resistant to the action of liquid petroleum gas.

Initial adjustments are the responsibility of the installer and are not chargeable to Lang Manufacturing Company.

When this appliance is installed with casters, it must be installed with the casters supplied, a connector complying with either ANSI Z21.69 • CSA

After the griddle is in its final position, adjust the legs to create 1/4-inch slant from back to front. This will allow the grease to run into the grease gutter and provide the proper combustion air for the burners (the plate is installed on the griddle with the proper slope. Differential leg adjustments are required to adjust for floor or counter slope only).

INITIAL START UP

WARNING

BEFORE LIGHTING, USE A SOAP AND WATER SOLUTION TO TEST ALL JOINTS FOR GAS LEAKS.

Pre-Power On

Clean the preservative coating from the griddle plate and splashguard. Add a mild detergent to hot water and wash the griddle plate and splashguard. Rinse with a damp sponge and dry with a clean rag.

• Plug the unit into a 115-volt power supply.

Power On

When the griddle is turned on for the first time, after being connected to power and gas, it may take it several tries to purge the gas lines and ignite the burners. If any of the burners fail to light during the initial trial for ignition the spark module will enter a lock out situation and the controller must be cycled off and then back on.

Once the burners ignite the griddle will automatically preheat the griddle to its default temperature of 125°F. This can be preset to a different temperature at the factory if notified.

Season the griddle

• When the burners go OFF, apply a thin coat of high-grade, non-salted vegetable oil

to the griddle surface.

• Rub the oil into the griddle surface with the flat side of a spatula or a towel.

• Recoat any dry spots that appear then wait two minutes and wipe off any excess oil.

• Repeat the seasoning process at 350°F and at 400°F.

OPERATION CONT’D

Changing the Griddle Temperature “On-the-Fly

There are three ways to set/adjust set point temperatures for this griddle. The first and simplest way is “On-the-Fly”. Make changes to temperature set points “On-the-Fly” as follows:

• While in normal operation, press either the LEFT or RIGHT arrow button. The display

indicates the current griddle section number and set point temperature.

• Use UP or DOWN arrows to increase or decrease the temperature value.

• When the change for the first section is complete press the left or right arrow button to

proceed to the next section or press the ENTER button to return to normal operation.

The control will handle “On-the-Fly” temperature settings differently depending on whether or not current “Fixed Set Points” or “Day Parts”, (see Manager Level Settings below), are in use. If neither “Fixed Set Points” nor “Day Parts” are setup the “On-the-Fly” settings will remain in effect until changed by the method indicated above, or until “Fixed Set Points” or “Day Parts” are input. If “Fixed Set Points” are setup, any “On-the-Fly” changes will be removed at Midnight. If “Day Parts” are setup, any “On-the-Fly” changes will be removed at the beginning of the next “Day Part”.

Manger Level Settings (MLS)

Turn the griddle on by pressing the Power button.

Press and hold the “Enter” and the “Up” arrow buttons for five seconds. If a user access code as been set, the display will prompt for the access code now. If not it will prompt for an “L or R” arrow button, this will scroll through one of ten Manager level settings.

Number of Sections

This setting should only be changed if installing a new controller.

Use the up or down arrow buttons to set the number of sections. The number of sections is determined by measuring (one section per foot) or counting the burners (one section per burner).

Once the number of sections is set press the ENTER button and this will advance you to the next setting.

Setting the Clock

The clock is only necessary if “Fixed Set Points” or “Day Parts” are set up. If no “Fixed Set Points” or “Day Parts” are setup there is no reason to set the clock, as it will not be displayed.

Setting the time starts with the Hour. Use the UP and DOWN arrow buttons to set the correct hour then press ENTER to move the Minute and then to AM/PM. Pressing ENTER after AM/PM is set will save changes.

Setting the Calibration

This setting should only be changed by authorized personal and only with temperature sensing devices that are authorized by the manufacturer.

Calibration adjustments always start with section 1. Use the UP and DOWN arrow buttons to adjust the displayed temperature to match the temperature sensed at the center of the sections top surface. Press the ENTER button to move to the next section. When the last section has been calibrated pressing the ENTER button will save the changes.

Setting the Temperature Unit

This setting allows the operator to change from Fahrenheit (F) to Celsius (C).

Use the Up or Down arrow to toggle between Fahrenheit (F) and the Celsius (C) display and Enter to save the changes.

OPERATION CONT’D

Setting Fixed Set Point Temperatures

Fixed set point temperatures provide for a more reliable temperature setting when normal procedures call for only one temperature setting per section all day long. If set points are changed “On-the-Fly”, for special Products and the operator forgets to change settings back to normal values, The control will remove the “On-the-Fly” changes at midnight. Setting up “Fixed Set Points” starts with section 1. Use the UP and DOWN arrow buttons to adjust the temperature. Press the ENTER button to move to the next section. When the last section’s temperature is set, pressing the ENTER will save the new set point values. The control will then prompt to set the clock.

Turning the Buzzer Alarms Off/On

This setting allows the operator to turn the audio (buzzer) temperature alarms off or on Use the up or down arrow to toggle between “Off” or “On”. Press the ENTER button to save selection.

Turning the Display alarms Off/On

This setting allows the operator to turn the visual (display) temperature alarms off or on Use the up or down arrow to toggle between “Off” or “On”. Press the ENTER button to save selection.

Day Part

“Day Parts” provide for a reliable means of setting temperatures when normal procedures require the use of multiple temperature settings per section throughout the day As many as six different “Day Parts” can be defined. If set points are changed “On-The-Fly”, for special products and the operator forgets to change the settings back to the normal values, the control will remove the “On-the-Fly” changes at the beginning of the next “Day Part”.

Setting up “Day Parts” begins with the control indicating the number of currant “Day Parts” setup and prompting for the user to indicate whether “Day Parts” are to be edited or deleted. Use the UP or DOWN arrow buttons to indicate EDIT or DELITE then press ENTER.

If EDIT is selected and no “Day Parts” currently exist, the control asks if a new “Day Parts” is to be added. Use the UP or DOWN to toggle between YES and NO then press ENTER. If YES is selected the control displays the new “Day Part” number (1-6) and prompts for setting the “Day Part” start time. Once the start time is set the control indicates the section number, the “Day Part” number, and a temperature value. Use the UP and DOWN arrow buttons to adjust the temperature value then press ENTER to advance to the next section. When all of the temperature set points have been adjusted and entered, the controller either asks if the user wants to add another “Day Part” or immediately prompts for setting the clock if six “Day Parts” have been setup.

If EDIT is selected with existing “Day Parts”, the control displays the first “Day Parts” start time. Use the UP and DOWN to adjust the start time. Once the start time is set the control indicates the section number, the “Day Part” number, and a temperature value. Adjust start times and set point temperatures as indicated above. When all existing “Day Parts” have been updated the control asks if a new “Day Part” is to be added. If YES is selected add “Day Parts” as indicated above. If NO is selected the controller will prompt for setting the clock.

If DELETE is selected the control will go through the existing “Day Parts” one at a time asking if the user wishes to delete the displayed “Day Part”. Use the UP and DOWN arrows to select YES or NO and press ENTER.

NOTICE

ETL # 3049061-2 Rev B

In order for the Day Part feature to work properly, you must set the two-start time. If only one start time is set, the control will use this setting as the default temperature setting. If the temperature is changed anytime during the Day Part, the control will revert to the Day Part temperature at the appropriate time set for that “Day Part”.
