UNPACKING
4.1 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.
4.2 Location
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.
4.3 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.
CAUTION: THE GRIDDLE 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.
CAUTION: ANY STAND, COUNTER OR OTHER DEVICE ON WHICH
THE GRIDDLE WILL BE LOCATED MUST BE
DESIGNED TO SUPPORT THE WEIGHT OF THE
GRIDDLE.

INSTALLATION
WARNING: INSTALLATION OF THE UNIT MUST BE DONE BY
PERSONNEL QUALIFIED TO WORK WITH PLUMBING.
IMPROPER INSTALLATION CAN CAUSE INJURY TO
PERSONNEL AND/OR DAMAGE TO EQUIPMENT. UNIT
MUST BE INSTALLED IN ACCORDANCE WITH ALL
APPLICABLE CODES.
NOTICE: The data plate is located inside the control compartment of
each griddle. The griddle serial number, gas specifications,
and clearance specifications are on the data plate. This
information should be carefully read and understood
before proceeding with the installation.
NOTICE: The installation of any components such as a vent hood,
grease extractors, fire extinguisher systems, must
conform to their applicable National, State and locally
recognized installation standards.
5.1 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. The gas should be
installed in one of two locations, from under the body or from the back. The
plug must be installed on the connection not used.
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 is already installed in the 6ft units. 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
must 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.

INITIAL START UP
6.1 Initial Lighting Procedure
Clean the preservative coating from the griddle plate and splash guard. Add a mild
detergent to hot water and wash the griddle plate and splash guard. Rinse with a
damp sponge and dry with a clean rag.
WARNING: BEFORE LIGHTING, USE A SOAP AND WATER
SOLUTION TO TEST ALL JOINTS FOR GAS LEAKS.
•Turn the main gas valve on.
•Light the pilot light by turning the control knob on the combination valve
counter-clockwise to the “PILOT” position. Push the control knob in. It will
take several minutes of holding the knob in, to clear the gas line of air during
the initial lighting. When the gas line is clear of air, hold a small flame next to
the pilot burner while you continue pushing the knob in. Release the knob.
The pilot light should remain lit.
•If the pilot flame goes out when you release the knob, re-light while pushing
the knob in for another 45 to 60 seconds.
•When the pilot continues burning, the pilot generator is hot enough to generate
sufficient voltage to lock in the safety pilot valve.
•Turn the combination valve knob to the “ON” position.
•Turn on the Jack in the Box® controller, follow the store Operations manual
for calibrating the controller.
6.2 Seasoning the Griddle Plate
•Turn on the controller.
•Observe the burners through the opening at the top of the control panel.
•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.
NOTICE: During the first few hours of operation you may notice a
small amount of smoke coming off the griddle, and a
faint odor from the smoke. This is normal for a new
griddle and will disappear after the first few hours of
use.

CAUTION: ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE
FROM COMBUSTIBLE MATERIALS.
CAUTION: KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND
DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY, TO

MAINTENANCE & CLEANING
WARNING: KEEP WATER AND SOLUTIONS OUT OF CONTROLS.
NEVER SPRAY OR HOSE CONTROL CONSOLE.
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.
8.1 Daily Cleaning
•Empty the grease drawer daily or whenever it is 3/4 full. It is easily removed
for washing.
•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 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.
8.2 Weekly Cleaning
•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.
•Clean the exterior of the appliance with hot water and a mild detergent to
maintain a gleaming appearance.
•Reseason the griddle plate after each cleaning.

MAINTENANCE & CLEANING CONT’D
NOTICE: Service on this, or any other, LANG appliance must be
performed by qualified personnel only. Consult your
authorized service station directory or call the factory
at 1-800-224-LANG (5264), or WWW.LANGWORLD.COM
For the service station nearest you.
8.3 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.
8.4 Testing Safeties and Controls
•The pilot combination valve can only be checked with a multi-meter that
measures milivolts.
•Connect the mulit-meter to the top terminal of the combination valve marked
“TH/TP” and the body of the combination valve.
•The voltage should read as follows: 400 to 500 MV with the burner off, 150
MV with the burner on.
•If no voltage is present at the combination valve, install a thermocouple tester
between the thermocouple and the combination valve, then retake the voltage
measurements.
•If no voltage is present, replace the thermocouple.
•If voltage is present, replace the combination valve.
8.5 NCC Console
Repairs or maintenance needed on the NCC Console is the responsibility of NCC.
Contact NCC for warranty work on the griddle control console.
