USE WITHOUT POWER CORD
If power cord cannot be used, then follow these wiring
instructions.
• Provide a way to easily shut off the electric power when
working on the water heater. This could be with a circuit
breaker or fuse block in the entrance box or a separate
disconnect switch.
• Install and connect a circuit directly from the main fuse or
circuit breaker box. This circuit must be the right size and
have its own fuse or circuit breaker.
A standard 1/2” conduit opening has been made in the water
heater junction box for the conduit connection.
• Use wire nuts and connect the power supply wiring to the
wires inside the water heater’s junction box.
• The water heater must be electrically “grounded” by the
installer. The unit will not operate unless it is properly
grounded. A green ground screw has been provided on the
water heater’s junction box. Connect ground wire to this
location. For complete grounding details and all allowable
exceptions, refer to the current edition of the National
Electrical Code, ANSI/NFPA 70.
