IMPORTANT READ FIRST IMPORTANT

CAUTION: EACH UNIT IS EXTREMLY 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.

CAUTION: ANY STAND, COUNTER OR OTHER DEVICE ON

WHICH GIDDLE WILL BE LOCATED MUST BE DESIGNED TO SUPPORT THE WEIGHT OF THE GRIDDLE.

CAUTION: SHIPPING STRAPS ARE UNDER TENSION AND CAN

SNAP BACK WHEN CUT.

DANGER: THIS APPLIANCE MUST BE GROUNDED AT THE

TERMINAL PROVIDED. FAILURE TO GROUND THE APPLIANCE COULD RESULT IN ELECTROCUTION AND DEATH.

WARNING: INSTALLATION OF THE UNIT MUST BE DONE BY

PERSONNEL QUALIFIED TO WORK WITH ELECTRICITY AND PLUMBING. IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT. UNIT MUST BE INSTALLED IN ACCORDANCE WITH ALL APPLICABLE CODES.

WARNING: BEFORE LIGHTING, USE A SOAP AND WATER

SOUTION TO TEST ALL JOINTS FOR GAS LEAKS.

WARNING: DURING INITIAL USE, OR AFTER SERVICE, IF PILOT

DOES NOT IGNITE ON FIRST TRY THE MAIN GAS VALVE MUST BE TURNED OFF FOR AT LEAST FIVE MINUTES.

NOTICE: The data plate is located left end of griddle behind

control door. The griddle voltage, gas specs, serial number, pipe size, and clearance specifications are on the data plate. This information should be carefully read and understood before proceeding with the installation.

INSIDE THIS APPLIANCE WHEN THE UNIT IS PLUGGED/WIRED INTO A LIVE RECEPTACLE. BEFORE REPLACING ANY PARTS, DISCONNECT THE UNIT FROM THE ELECTRIC POWER SUPPLY.

CAUTION: USE OF ANY REPLACEMENT PARTS OTHER THAN

THOSE SUPPLIED BY LANG OR THEIR AUTHORIZED DISTRIBUTORS CAN CAUSE BODILY INJURY TO THE OPERATOR AND DAMAGE TO THE EQUIPMENT AND WILL VOID ALL WARRANTIES.

EQUIPMENT DESCRIPTION

GAS GRIDDLE

EXTERIOR

♦ Griddle

¾ The griddle dimensions are 17” (43.18cm) High, 30” (76.20cm) Deep, and width is dependent on

the actual model number.

¾ The Sides, Bottom, and Rear wall are constructed of double wall stainless steel, which allows

closer installation to combustible surfaces.

¾ The griddle surface is made of 1” thick, highly polished steel to reduce hot and cold spots, recovery

problems, warping, and ensure even heat to the edges of the griddle.

♦ AGC Hood

¾ The Hood dimension (not including griddle) are 19 1/2” (49.5cm) High with hood down, 38 3/8”

(97.5cm) High with hood up, 36 7/8” (93.5cm) Deep, and 23 7/8” (58.6cm) Wide.

¾ The Hood wrap is constructed of stainless steel and uses infrared heat to broil the product.

CONTROLS

The Gas Griddle is available either with the Lang Accu-Temp controls (G-2TI, G-3TI, G-4TI, G-5TI, G6TI), the Lang Accu-Temp Direct Spark controls (G-2TDSI, G-3TDSI, G-4TDSI, G-5TDSI, G-6TDSI), the Lang Selectronic controls (G-2EI, G-3EI, G-4EI, G-5EI, G-6EI,), and the Lang Selectronic Direct Spark controls (G-2EDSI, G-3EDSI, G-4EDSI, G-5EDSI, G-6EDSI):

♦ G-TI (Thermostatic ignition)

¾ Each twelve-inch section has its own easy to use manual thermostat with a temperature range from

175°F to 450°F in 50° increments.

¾ Each twelve-inch section has it’s own individual burner for high efficiency, quick recovery and

outstanding performance.

♦ G-TDSI (Direct Spark, Thermostatic ignition)

¾ Same dependable control features as the G-TI with the convenience of the direct spark ignition

system.

♦ G-EI (Electronic ignition)

¾ Each twelve-inch section has its own temperature selector switch that snaps into place to lock in

any temperature from 175°F to 450°F in 25° increments.

¾ Each twelve-inch section of the griddle is controlled by an area sensitive RTD probe, which can

sense and react to a temperature change of +/- 4°F.

¾ Each twelve-inch section has it’s own individual burner for high efficiency, quick recovery and

outstanding performance.

♦ G-EDSI (Direct Spark, Electronic ignition)

¾ Same great control features as the G-EI with the convenience of the direct spark ignition system.

INSTALLATION

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 loss or damage, which 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 Company. File your claim with the carrier.

Prior to un-crating, move the griddle as near 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.

ELECTRICAL CONNECTION

The griddle is supplied with a cord and plug. The receptacle is not provided with the griddle.

Follow the receptacle manufacturer’s instructions when connecting the receptacle to the power supply.

GAS CONNECTION

This griddle is manufactured for use with the type of gas indicted on the nameplate. Contact the factory if your type of gas does not match the nameplate data.

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.

This regulator must be installed in the gas supply line. (Note the direction of the gas flow arrow.) 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.

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.

GAS GRIDDLE

1) Verify connections at plug and terminal block

2) Incoming Volt - Single Phase L1______

3) Gas pressure is set for 4.5” WC (Natural Gas), 9” WC (Propane).

Ensure that the regulator is installed in the correct direction.

4) Ensure Griddle body is tilted 1/8” lower in front. Confirm there is

4” clearance below Griddle.

5) Ensure that burner flame is stable and not lifting off of burner.

Flame should light around the “U” of each burner with no hesitation. Height of flame should be 1 1/4” to 1 1/2” from burner surface. Flames must not lift off of burner ports.

START-UPS

6) Ensure that spark electrode does not continue to spark after ignition.

The tip of the spark electrode and sensor electrodes must have flame on them and glowing red.

7) Verify actual temperature at 350 °F ________ °F.

Note: Install thermocouple wire in center of 12” section for that control area. Let griddle cycle off and on 3 times before recording temperature.
