Electrical Connections
All electrical wiring and connections must be in accordance with the National
Electric Code ANSI/NFPA No. 70 (latest edition), or the Canadian Electrical
Code C22.1 (latest edition) and any local codes, which may apply. The water
heater must be electrically grounded.
If a flexible line cord and plug is permitted by local code, then provide a (3)
three wire grounding type receptacle within 6 feet (1.9 m) of the water heater
and use the flexible cord provided. Do not plug the line cord into a receptacle
that can have its power supply interrupted by a switch that is used to turn on
and off lights.
If wiring in conduit is required, remove the flexible line cord from the jacket and
install a 1/2" electrical conduit connector and connect 110/120 volt power
source. Connect the hot, neutral, and ground leads of the electrical supply to
the corresponding locations that were connected to the flexible line cord.

Refer to the rating plate located on the water heater for correct model
identification.
CAUTION
Turn off or disconnect the electrical power supply to the water heater before
servicing. Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation. Verify proper
