12. Electrical Wiring
Consult a qualified electrician for the electrical work.
Do not connect electrical power to the unit until all electrical wiring has been completed.
Disconnect Power
This appliance must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70. In Canada, the latest CSA C22.1 Electrical Code.
Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.
Field wiring to be performed at time of appliance installation.
WARNING
Electrical Shock Hazard
Do not turn power on until electrical wiring is finished. Disconnect power before servicing. Failure to do so may result in death or serious injury from electrical shock.
•The electrical supply required by the water heater is 120V AC at 60 Hz.
The power consumption may be up to 125W or higher if using optional accessories.
Use an appropriate circuit.
•Do not disconnect the power supply when not in use. When the power is off, the freeze prevention in the water heater will not activate, resulting in possible freezing damage.
•Do not let the power cord contact the gas piping.
Tie the redundant power cord out- side the water heater. Putting the redundant length of cord inside the water heater may cause electrical interference and faulty operation.
Ground
• To prevent electrical shock, provide a ground with resistance less than 100 . An electrician should do this work.
•A grounding screw is provided on the back in the junction box.
Do not connect the ground to the city water or gas piping. Do not tie the ground to a tele- phone line.
Breaker Installation
•Mount a device which shuts off the electrical path automatically (leakage breaker) when electrical leakage is detected.
