Installation, Operation and Care of MGG SERIES GAS GRIDDLES PLEASE KEEP THIS MANUAL FOR FUTURE USE GENERAL Vulcan griddles are produced with quality workmanship and material. Proper installation, usage and maintenance of your griddle will result in many years of satisfactory performance. It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions provided.
The installation location must allow adequate clearances for servicing and proper operation. A minimum front clearance of 32" is required. Do not obstruct the flow of combustion and ventilation air. Adequate clearance for air openings into the combustion chamber must be provided. Make sure there is an adequate supply of air in the room to replace air taken out by the ventilating system. Do not permit fans to blow directly at the griddle. Wherever possible, avoid open windows next to the griddle.
GAS CONNECTIONS CAUTION: Gas supply connections and any pipe joint compound must be resistant to the action of propane gases. Location of the gas inlet is at the rear of the griddle. Codes require that a gas shutoff valve must be installed in the gas line ahead of the griddle. Connect gas supply. Make sure the pipes are clean and free of obstructions. Griddles are equipped with fixed burner orifices for use with natural or propane gas and no adjustment is necessary.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT SWITCH INDICATING THAT YOU ARE WORKING ON THE CIRCUIT. WARNING: APPLIANCES EQUIPPED WITH A FLEXIBLE ELECTRIC SUPPLY CORD ARE PROVIDED WITH A THREE-PRONG GROUNDING PLUG. IT IS IMPERATIVE THAT THIS PLUG BE CONNECTED INTO A PROPERLY GROUNDED THREE-PRONG RECEPTACLE. IF THE RECEPTACLE IS NOT THE PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN. DO NOT REMOVE THE GROUNDING PRONG FROM THIS PLUG.
OPERATION WARNING: THE GRIDDLE AND ITS PARTS ARE HOT. CLEANING OR SERVICING THE GRIDDLE.
