Electrical
Connection
The water heater requires 120 VAC, 60 Hz power from a properly grounded circuit.
If using the 6 foot long power cord, plug it into a standard 3 prong 120 VAC, 60 Hz properly grounded wall outlet.
The wiring diagram is located on the Technical Sheet attached to the inside of the front cover.
The water heater must be electrically grounded in accordance with local codes, or in the absence of local codes
with the National Electrical Code, ANSI/NFPA 70 and/or the CSA C22.1, Canadian Electrical Code.
