SECTION VIII: ELECTRICAL CONNECTIONS
WARNING
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 operation after servicing.
All electrical wiring must be installed and grounded in accordance with local codes, or in the absence of local codes, the National Electrical Code, ANSI/NFPA 70 and/or CSA C22.2 Electrical Code.
The water heater must be wired to a 120 VAC, 60 Hz, 15A power supply. The water heater should be connected to a GFI outlet and wired on a separate circuit and breaker. If a flexible line cord and plug is permitted by local code, then provide a three wire GFI grounding type receptacle within reach of the line cord provided on the control box. Do not plug the line cord into a receptacle that can have the power supply interrupted by a switch that is used to control lights or another appliance.
If wiring in conduit is required, remove the line cord and strain relief bushing in the control panel and install an electrical conduit connector. Connect the hot, neutral, and ground leads to the terminal block using quick connect terminals. Refer to the wiring diagram for the correct terminal locations for each wire lead.
CAUTION
Do not energize the electric circuit before the water heater tank is filled with water.
This controller is Polarity sensitive. If the Hot and Neutral Supply voltage is reversed, the controller will not sense flame and the water heater will not operate. Verify polarity before connecting the water heater.
