ELECTRICAL CONNECTIONS
• Follow the electrical code requirements of the local authority having jurisdiction.
In the absence of such requirements, follow the current edition of the National
Electrical Code ANSI/NFPA 70 in the U.S. or the current edition of CSA C22.1
Canadian Electrical Code Part 1 in Canada.
• When servicing or replacing parts within the water heater, label all wires prior to
disconnection to facilitate an easy and error-free reconnection. Wiring errors can
cause improper and dangerous operation. Verify proper operation after servicing.
• Failure to observe these warnings could result in personal injury or death.
WARNING
All Indoor models come with a power plug instead of a junction box. The following procedure is for
outdoor model only.
1. The water heater must be electrically grounded. Do not attach the ground wire to either the gas or
the water piping.
2. The water heater requires a 120 VAC, 60 Hz electrical power supply that is properly grounded.
• A proper disconnect (i.e. on/off switch, power plug, etc.) controlling the main power to the water
heater must be provided for service reasons. (Must comply with local codes.)
• Connect the power supply to the water heater exactly as shown in the wiring diagram.
3. A green screw is provided in the junction box to ground the connection.
4. The water heater can be hardwired or wired to a plug-in.
5. The use of a surge protector is recommended in order to protect the unit from power surges.
