Operating Instructions Installation Instructions Safety Instructions Installing the water heater. 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. Ground screw Electrical Connections WARNING Conduit connector Junction box cover Wire connections Water heater junction box. 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.

Check Local Electrical Codes, as they will also apply. Condensation Condensation can form on the tank when it is first filled with water. Condensation might also occur with a heavy water draw and very cold inlet water temperatures. This condition is not unusual, and will disappear after the water becomes heated. If, however, the condensation continues, examine the piping and fittings for possible leaks.
