Viking RDGSU2005BSS Installation Instructions - Page 7

Electrical & Gas Requirements Electrical Requirements There is no connection necessary beyond plugging the unit into a polarized, grounded, 120 volt, 60 Hz, 15 amp circuit. A minimum of 120VAC is required for proper operation of gas ignition systems. DO NOT use a GFI circuit. This circuit, however, MUST be grounded and properly polarized. The unit is equipped with 16-3 SPT2 power cord. Note: If electrical power is not supplied or is interrupted, the open top burners will have to be lit manually with a match. Gas Connection The gas supply (service) line must be the same size or greater than the inlet line of the appliance. All cooktops use a 1/2" (1.3 cm) I.D. NPT (Sch40) inlet. Sealant on all pipe joints must be resistive to LP/Propane gas. These cooktops are designed specifically for natural gas. An (LP) gas conversion kit ships standard with every unit. Before beginning installation verify that the model is compatible with the intended gas supply. IMPORTANT: Any conversion required must be performed by a qualified licensed plumber or gas service company. The proper conversion kit must be ordered from your authorized service agency or dealer. Manual shut-off valve: • The installer-supplied valve must be installed in the gas service line ahead of the appliance and regulator in the gas stream and in a position where it can be reached quickly in the event of an emergency. In Massachusetts: A "T" handle type manual gas valve must be installed in gas supply line to the appliance. Pressure regulator: • All heavy-duty, commercial-type cooking equipment must have a pressure regulator on the incoming service line for safe and efficient operation, since service pressure may fluctuate with local demand. The regulator supplied with the cooktops must be installed before any gas connections are made. • Manifold pressure should be checked with a manometer; natural gas requires 5.0" WCP and LP/Propane requires 10.0" WCP. Incoming line pressure upstream for the regulator must be 1" WCP higher than the manifold pressure in order to check the regulator. The regulator used on this cooktop can withstand a maximum input pressure of 1/2 PSI (14.0" WCP). If the line pressure is in excess of that amount, a stepdown regulator will be required. • The appliance must be disconnected from the gas supply piping system during any pressure testing of that system. 12 Electrical & Gas Requirements Rigid Connections: • Incoming gas is brought from an intake pipe (not supplied) at the rear of the unit to the pressure regulator; then to the manifold pipe for distribution. The only connection necessary is from the service supply, through the shut-off valve (not supplied), to this intake pipe (not supplied) to the regulator supplied, but not connected through the cooktop. In Massachusetts: This appliance must be installed with a 36" (3-foot) long flexible gas connector. CAUTION Before placing the cooktop into operation, always check for gas leaks with a soapy water solution or other acceptable method. DO NOT USE AN OPEN FLAME TO CHECK FOR LEAKS. LP/Propane Conversion The RDGSU models are field convertible to LP/Propane gas. The orifice spuds and regulator must be physically changed. See conversion kit and instructions included with your cooktop. Gas conversions and initial installation adjustments are not the responsibility of the manufacturer. Initial Ignition of Burners All cooktops are tested before leaving the factory. Field adjustments may be necessary for proper mixture of gas and air for proper operation. When the cooktop is connected to gas and electrical service, it should be adjusted by a qualified technician. If it is not, contact your dealer for the name of their authorized service agency in your area. Proper Lighting and Shutdown Instructions 1. To ignite the surface burners, turn the knob counter clockwise to any position. 2. Upon ignition of the surface burner, turn the knob to the desired position, (HI, Med, or Low). 3. To shutdown the burner, turn knob clockwise to the OFF position. 4. In case of failure, shut the gas OFF using the installer supplied manual shut-off valve. 13
