ELECTRICAL SUPPLY REQUIREMENTS

WARNING
Electrical Shock Hazard
An electrical ground is required on this ap-
pliance.
If a cold water pipe is interrupted by plastic,
nonmetallic gaskets, or other insulating
materials, do not use for grounding.
Do not ground to a gas pipe.
Do not use a fuse in the neutral or grounding
circuit. It could result in an electrical shock.
Check with a qualified electrician if you are
in doubt as to whether the appliance is
properly grounded.
Failure to follow these instructions could
result in serious injury or death.
GENERAL
If codes permit, and a separate grounding wire
is used, it is recommended that a qualified
electrician determine that the grounding path
is adequate.
The following information applies to appliance
and vent system wiring:
• A 3- or 4-wire, single phase, 120/240-volt,
60 Hz, AC-only electrical supply, or a 3- or
4-wire, 120/208-volt supply, if specified on
the model/serial rating plate, is required on
a separate 40-ampere circuit, fused on both
sides of the line.

• A time-delay fuse, or circuit breaker, is
recommended. The fuse must be sized as
per local codes in accordance with the elec-
trical rating of the appliance specified on
the model/serial rating plate, which is lo-
cated on the left side of the vent's plenum.
• The cooktop must be connected with cop-
per wire only.
• Wire sizes and connections must conform
to the requirements of the National Electri-
cal Code, ANSI/NFPA 70—latest edition*,
and all local codes and ordinances. Wire
sizes and connections must conform with
the rating of the appliance. Copies of the
standards listed above may be obtained
from:
* National Fire Protection Association
Batterymarch Park

• The appliance should be connected directly
to the fused disconnect (or circuit breaker)
through flexible, armored, or nonmetallic
sheathed, copper cable with grounding wire.
The flexible, armored cable that extends
from the appliance should be connected
directly to the junction box.
• Locate the junction box to allow as much
slack as possible between the junction box
and the appliance so that the appliance can
be moved if servicing is ever necessary. Do
not cut the conduit.
• A U.L.-listed,
tor must be provided at the junction box.
• A wiring diagram is located in the "Tech
Tips" section of this manual.
