WARNING

ELECTRICAL CONNECTIONS

A qualified electrician must provide a separate branch circuit with copper conductors, over current protective
device and suitable disconnecting means. 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 at the top of the water
heater. An opening for 1/2" or 3/4" electrical fitting is provided for field wiring connection. The voltage
requirements and wattage load for the water heater are specified on the rating label 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. Nonmetallic-sheathed cable,
metallic conduit or metallic sheathed cable not approved to be used 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.

The tank must be full of water before heater is turned on. The water heater
warranty does not cover damage or failure resulting from operation with an empty
or partially empty tank. Make certain the drain valve is completely closed. Open
the shut-off valve on the cold water supply line. Open each hot water faucet slowly
to allow the air to vent from the water heater and piping. A steady flow of water
from the hot water faucet(s) indicates a full water heater.
Water heater junction box
A proper ground connection is essential. The presence of water in the piping and
water heater does not provide sufficient conduction for a ground. Nonmetallic pip-
ing, dielectric unions, flexible connectors, etc., can cause the water heater to be
electrically isolated.
