and Griddle

•A neutral supply wire must be provided from the power source (breaker/fuse panel) because criti- cal range components, including the surface burner spark re-ignition modules, require 120 VAC to operate safely and properly. An improper 120 VAC power supply will cause malfunction, damage to this appliance, and possibly create a condition of shock hazard. If the correct power supply circuit is not provided, it is the responsibil- ity 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 electri- cian. In the absence of local codes and ordi- nances, the power supply connection shall be in accordance with the National Electrical 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.

•Electric wiring diagrams and schematics have been placed in the toe kick area of the range for access by a qualified service technician.

IMPORTANT

For all gas ranges with electric griddle, dedicated 20 AMP service is required for proper operation.

Before you plug in an electrical cord, be sure all controls are in the OFF position.

For appliances equipped with a cord and plug, do not cut or remove the ground prong. It must be plugged into a matching grounding type receptacle to avoid electrical shock. If there is any doubt as to whether the wall receptacle is properly grounded, the customer should have it checked by a qualified electrician.

Installer - show the owner the location of the circuit breaker or fuse. Mark it for easy reference.

CAUTION

The appliance must be isolated from the gas supply piping system by closing its individual manual shut- off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5kPa.).

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 (3.5kPa.).

When checking the manifold gas pressure, the inlet pressure to the regulator should be at least 6.0" (14.9 mb) W.C. for natural gas or 11.0" (27.4 mb) for propane.

Do not attempt any adjustment of the pressure regulator.
