Step 6: Electrical Requirements, Connection & Grounding • Prior to installing appliance, always disconnect appliance electrical supply cord, if so equipped, from wall receptacle. If appliance is hard-wired to power supply, disconnect power to unit by turning off the proper circuit breaker or disconnecting the proper fuse. Lock service panel to prevent power from being turned ON accidentally. Dual Fuel range models can be connected or hardwired to the power supply as described on Page 15.

PHASE Single Single Single • A neutral supply wire must be provided from the power source (breaker/fuse panel) because critical range components, including the surface burner spark re-ignition module, require 120 VAC to operate safely and properly. An improper 120/ 240 VAC power supply will cause malfunction, damage this appliance, and possibly create a condition of shock hazard. If the correct power supply circuit is not provided, it is the responsibility and obligation of the installer and user to have proper power supply connected. This must be accomplished in accordance with all applicable local codes and ordinances by a qualified electrician. In the absence of local codes and ordi- nances, the power supply connection shall be in accordance with the National Electric Code. • Observe all governing codes and ordinances when grounding. In the absence of these codes or ordinances observe National Electrical Code ANSI/NFPA No. 70 current issue. See Pages 15 and 16 for grounding method. • Electrical wiring diagrams and schematics have been placed in the toe kick area of the range for access by a qualified service technician. • The ranges are to be connected to a 240/208 VAC power supply. CAUTION 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 (3.5 kPa.). The appliance and its individual shut off valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 1/2 psig (3.5 kPa.). When checking the manifold gas pressure, the inlet pressure to the regulator should be at least 6" W.C. (14.9 mb) for natural gas or 11" W.C. (27.4 mb) for propane. Do not attempt any adjustment of the pressure regulator. 13
