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 absence 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 threeprong grounding plug (with polarized parallel blades). IT MUST BE
PLUGGED INTO A MATING GROUNDING TYPE RECEPTACLE, CONNECTED 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 properly 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 accordance 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 appliance 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.
