Installing the New Water Heater (cont’d)

Filling the Water Heater

You must provide all wiring of the proper size outside of the water heater. You must obey local codes and electric company requirements when you install this wiring.

CAUTION

Never use this water heater unless it is completely filled with water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater.

To fill the water heater with water:

1.Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater.

2.Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open when the water heater is in use.

3.To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping.

4.Check all new water piping for leaks. Repair as needed.

Wiring

The water heater comes equipped with a 7 foot power cord which can be used to connect to a 110/120 volt power source if, (1) local codes allow, and (2) there is a three prong receptacle available. This unit must have a grounded outlet to operate.

You must provide all wiring, (1) to a receptacle or, (2) between the water heater and junction box when the power cord is not used.

WARNING

This appliance must be grounded for safety and to insure proper operation. Failure to do so could result in DEATH, SERIOUS BODILY INJURY OR PROPERTY DAMAGE.
