STEP THREE: ELECTRICAL REQUIREMENTS & GROUNDING

THIS APPLIANCE MUST BE CONNECTED TO A RECEPTACLE ON A CIRCUIT RATED 120 VOLTS, AC 60HZ., 15 AMPERE

Recommended Grounding Method

Always disconnect electric supply cord from wall outlet before servicing this appliance.

Observe all governing codes and ordinances when grounding. In the ab- sence of these codes or ordinances observe National Electrical Code ANSI/ NFPA No. 70 Current Issue.

This appliance is factory equipped with a power supply cord with a three- prong grounding plug (with polarized parallel blades). IT MUST BE PLUGGED INTO A MATING GROUNDING TYPE RECEPTACLE, CON- NECTED TO A CORRECTLY POLARIZED 120 VOLT CIRCUIT. Improper polarization will cause malfunction (such as continuous sparking of the burner igniters) and may damage this appliance and could create a condition of shock hazard at the igniter of each burner. If the circuit does not have a grounding type receptacle, it is the responsibility and obligation of the installer or user to have the existing receptacle changed to a prop- erly grounded and polarized receptacle in accordance with all applicable local codes and ordinances by a qualified electrician. In the absence of local codes and ordinances, the receptacle replacement shall be in accor- dance with the National Electrical Code. THE THIRD GROUND PRONG

SHOULD NOT UNDER ANY CIRCUMSTANCES, BE CUT OR REMOVED. See Fig. 2.

Alternate Grounding Method - See Fig. 3.

If installing a properly grounded wall receptacle is impossible at the time of installation, consult your local electrical inspector for permission to connect a temporary adapter (with polarized blades) which could be plugged into your present 2-wire receptacle. This is not recommended.

If this is done, you must attach the lug and/or the green adapter wire to the receptacle cover plate screw. Ground from it to a grounded metal cold water pipe,* see Fig. 3. DO NOT GROUND TO A GAS SUPPLY PIPE.

You must permanently ground the adapter before connecting the appli- ance to the power supply.

CAUTION: Attaching the adapter ground wire to the wall receptacle cover screw does not ground the appliance unless the cover screw is grounded through the house wiring.

If there is any doubt as to whether the wall receptacle is properly grounded, the customer should have it checked by a qualified electrician.

Cold water pipe must have metal continuity to the electrical ground and not be interrupted by plastic, rubber or other electrically insulating connectors (including water meter or pump) without adding a jumper wire at these connections. See Fig. 4.
