INSTALLATION
NOTE
• DO NOT connect the wire to the circuit panel at
this time.
Electrical Requirements
Observe all governing codes and local ordinances
1
A 3-wire or 4-wire single-phase 120/240 or
120/208 Volt, 60 Hz AC-only electrical supply is
required on a separate circuit fused on both
sides of the line (time-delay fuse or circuit
breaker is recommended). DO NOT fuse
neutral. The fuse size must not exceed the
circuit rating of the appliance specified on the
nameplate.
2
This appliance can consume up to 3500 W at
240 VAC. At least 30 Amp circuit breaker with
#8 AWG must be used.
WARNING
• Do not use an extension cord with this
appliance. Doing so may result in a fire, electrical
shock, or other personal injury.
NOTE
• Wire sizes and connections must conform to the
fuse size and rating of the appliance in
accordance with the National Electrical Code
ANSI/NFPA No. 70, latest edition, and local codes
and ordinances.
3
The appliance should be connected to the
fused disconnect (or circuit breaker) box
through flexible armored or nonmetallic
sheathed cable. The flexible armored cable
extending from this appliance should be
connected directly to the grounded junction
box. The junction box should be located as
shown in Dimensions and Clearances with
as much slack as possible remaining in the
cable between the box and the appliance, so it
can be moved if servicing is ever necessary.
4
A suitable strain relief must be provided to
attach the flexible armored cable to the
junction box.
Electrical Connection
Connect the flexible armored cable that extends
from the surface unit to the junction box using a
suitable strain relief at the point the armored cable
enters the junction box. Then make the electrical
connection as follows.
Electrical ground is required on this appliance.
This appliance is manufactured with a supply wire
and a frame-connected green or bare copper
grounding wire.
NOTE
TO ELECTRICIAN:
• The armored cable leads supplied with the
appliance are UL-listed for connection to larger
gauge household wiring. The insulation of the
leads is rated at temperatures much higher than
the temperature rating of household wiring. The
current-carrying capacity of the conductor wire
is governed by the temperature rating of the
insulation around the wire, rather than the wire
gauge alone.
WARNING
• DO NOT ground to a gas supply pipe. DO NOT
connect to electrical power supply until
appliance is permanently grounded. Connect the
ground wire before turning on the power.
• This appliance is equipped with a copper
conductor flexible cable. If connection is made to
aluminum house wiring, use only special
connectors which are approved for joining
copper and aluminum wires in accordance with
the National Electrical Code and local codes and
ordinances. Improper connection of aluminum
house wiring to copper leads can result in a
short circuit or fire. Follow the connector
manufacturer's recommended procedure
closely.
Where Local Codes Permit Connecting
the Appliance-Grounding Conductor to
the Neutral (White) Wire
Observe all governing codes and local ordinances.
1
Disconnect the power supply.
2
At the circuit breaker box, fuse box or junction
box, connect appliance and power supply
cable wires as shown.
