Operating Instructions Installation Instructions Safety Instructions Installing the water heater. Ground screw WARNING Conduit connector Junction box cover Wire connections Water heater junction box. CAUTION: The presence of water in the piping and water heater does not provide sufficient conduction for a ground. Non-metallic piping, dielectric unions, flexible connectors etc. can cause the water heater to be electrically isolated. Electrical Connections A separate branch circuit with copper conductors, overcurrent protective device and suitable disconnecting means must be provided by a qualified electrician. All wiring must conform to local codes or latest edition of National Electrical Code ANSI/NFPA 70. The water heater is completely wired to the junction box inside jacket at the top front of the water heater. An opening for 1/2″ or 3/4″ electrical fitting is provided for field wiring connections. The voltage requirements and wattage load for the water heater are specified on the rating plate on the front of the water heater. The branch circuit wiring should include either: Metallic conduit or metallic sheathed cable approved for use as a grounding conductor and installed with fittings approved for the purpose. Non-metallic sheathed cable, metallic conduit or metallic sheathed cable not approved for use as a ground conductor shall include a separate conductor for grounding. It should be attached to the ground terminals of the water heater and the electrical distribution box. NOTICE: This guide recommends minimum branch circuit sizing and wire size based on National Electric Code. Refer to wiring diagrams in this manual for field wiring connections.
