Exterior Construction
The griddle dimensions are 17” (43.18cm) High, 30” (76.20cm) Deep, and width is dependent on the actual model number.
The Sides, Bottom, and Rear wall are constructed of double wall stainless steel, which allows closer installation to combustible surfaces.
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.
Operation
• Each 12” section has its own snap-action thermostat and gas valve that are fully “ON” or fully “OFF”.
• The control has factory congurable maximum and minimum temperature settings. The maximum temperature value can be set at 550°F (288°C). The minimum temperature value can be set at 200°F (93°C).
Technical
• Griddle operates on either Natural gas or Propane, which must be specied when ordering.
It is shipped with a power cord and plug attached.
• Floor space required is 30” (76.20cm) Deep, and width is 2 ft, 3ft, 4ft, 5ft, or 6ft depending on actual model number.
• The griddle weighs 255, 336, 435, 530, 610 lbs. depending on actual model number.

CAUTION
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.
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 nal 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.
Level unit by adjusting the (4) legs for accurate and perfect lineup with other units.

VENTILATION & CLEARENCE
CLEARANCE
For use on non-combustible countertops only. Combustible and non-combustible material must be at least 48” (120cm) from the top of the appliance. Combustible material must be 5” (150mm) from the sides and back, while clearance to non-combustible material on the sides and back is 0”. Adequate clearance should also be provided for proper operation and servicing.
AIR SUPPLY
Make certain not to obstruct the ow of combustion and ventilation air. Provisions for adequate air supply must be furnished. The legs supplied with the unit must be installed. Make certain that air intake openings in the bottom of the appliance are not obstructed. They are essential for proper combustion and operation of the appliance.
EXHAUST CANOPY
It is essential that facilities be provided over the griddle to carry off fumes and gases. However, the unit should not be directly connected to a ue or stack.

INSTALLATION
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 specied is installed on each appliance.
This regulator must be installed in the gas supply line. (Note the direction of the gas ow 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 re. 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 International.
After the griddle is in its nal position, adjust the legs to create 1/8 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.
DANGER: THIS APPLIANCE MUST BE GROUNDED AT THE TERMINAL
PROVIDED. FAILURE TO GROUND THE APPLIANCE COULD RESULT IN ELECTROCUTION AND DEATH.
INSTALLATION OF THE UNIT MUST BE DONE BY PERSONNEL
