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 driver. 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, 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.

Uncrate the appliance 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.

DATA PLATE

A data plate is located on the left end of the griddle, just behind and over the top of the control panel. The appliance’s voltage, wattage, gas type, gas pressure and clearances are located on this plate. This information should be carefully read and understood before proceeding with the installation.

VENTILATION AND CLEARANCES

This appliance must be installed under a ventilation hood. The installation of any components such as vent hoods, grease extractors, or fire extinguisher systems, must conform to their applicable nationally recognized installation standards. Minimum clearances from combustible materials shall be: 6 inches from side walls 14 inches from back wall Minimum clearance from any surface shall be: 4 inches from bottom Keep the appliance area free and clear of combustible material and do not obstruct the flow of combustion or ventilation air.

GAS CONNECTION

DANGER

FIRE AND EXPLOSION HAZARD

AS WITH ANY GAS APPLIANCE ON CASTERS, ANY LANG GAS GRIDDLE, GAS

CLAMSHELL®, OR GAS CONVECTION OVEN ON CASTERS MUST BE INSTALLED WITH:

A CONNECTOR THAT COMPLIES WITH THE STANDARD FOR CONNECTORS FOR

MOVABLE GAS APPLIANCES, ANSI Z21.69A LATEST EDITION

AND

A QUICK DISCONNECT THAT COMPLIES WITH THE STANDARD FOR QUICK DISCONNECT

DEVICES FOR USE WITH GAS FUEL, ANSI Z21.41 LATEST EDITION.

AND

A TETHER OR OTHER MEANS TO LIMIT APPLIANCE MOVEMENT WITHOUT RELIANCE ON

THE GAS SUPPLY PIPING. INSTALL THE EYEBOLT INTO THE HOLE PROVIDED IN THE

REAR OF THE APPLIANCE, AND SECURELY ATTACH THE TETHER TO THE EYEBOLT.

FAILURE TO INSTALL THESE PARTS CAN LEAD TO LEAKAGE OF GAS AND RESULTING

FIRE, EXPLOSION, PERSONAL INJURY AND DEATH.

All gas connectors must be in accordance with local codes and comply with the National Federal Gas code ANSI Z223.1 latest edition. This griddle is manufactured for use with the type of gas indicated on the nameplate. Contact the factory if your type of gas does not match the nameplate data. 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. A pressure regulator and gas valve are supplied with each appliance. This regulator and valve 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: Griddle: 5 inches water column for natural gas. 10 inches water column for propane.

Broiler: 3 1/2 inches water column for natural gas. 6 inches water column for propane. When replacing the plug in the manifold, a use a pipe joint compound or sealant 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.

WARNING

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

LEAKS

After the griddle is in its final position, adjust the legs so the griddle body is level back to front. This will allow the grease to run into the grease gutter and provide the proper combustion air for the burners. This appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any testing of that system at test pressures in excess of 1/2 PSIG (3.45 kPA) and the appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG (3.45 kPA).

WARNING

ELECTRICAL GROUNDING INSTRUCTIONS

THIS APPLIANCE IS EQUIPPED WITH A 3-PRONG (GROUNDING) PLUG FOR YOUR

PROTECTION AGAINST SHOCK HAZARD AND MUST BE PLUGGED DIRECTLY INTO A

PROPERLY GROUNDED 3-PRONG RECEPTACLE.

DO NOT CUT OR REMOVE THIS GROUNDING PRONG FROM THE PLUG.
