Electrical Connections
(In addition to the instruction manual.)
All electrical wiring and connections must be in accordance with the National Electric Code ANSI/NFPA No.
If a flexible line cord and plug is permitted by local code, then provide a (3) three wire grounding type receptacle within 6 ft (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.
Turn off the water heater gas control and disconnect power to the water heater and Accessory Module. If wiring in conduit is required, cut the flexible line cord at least 6 in. (15.2 cm) from the bushing. Unscrew and remove the Setback Control Junction Box Assembly lid. Pull the cord into the junction box assembly housing. Cut the three wires from the line cord at the bushing inside of the housing. Enlarge the hole in the back of the junction box assembly to receive a 1” electrical conduit connector. Wire the power supply into the circuit at the appropriate locations.
Replace the Setback Control Junction Box Assembly cover and
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 operation after servicing.
