POWERED ANODE SYSTEM

These heaters are equipped with a powered anode system. The powered anode system provides corrosion protection to

the tank by supplying a low voltage current to the titanium anode rods and then periodically comparing this current with the

potential between the anode rod and tank wall to make corrections. The powered anode system is designed to extend the

tank life without requiring anode rod replacement. The powered anode system consists of two titanium powered anode

rods (31 ⅞ inches

(81 cm)

long), located in the front top of the water heater tank, and the powered anode control module

located on the right side of the control panel.

The powered anode rod must have the electrical power supply connected at all times in order to provide corrosion protection

to the water heater tank. If the electrical supply to the water heater is to be off for an extended period of time, the water

heater must be drained. Turning off the lighted switch on the front panel to shut off the water heater will not turn off the

powered anode system, as long as the line cord is plugged in and the breaker is left on.

The powered anode control module is located on the right vertical side of the control panel inside the surround panel. The

control has a LED indicator light to show the status of operation. When the tank is filled with water and the power supply is

on to the water heater, the light should have a steady green glow to indicate that protection current is flowing and operating

normally. If the indicator light is not glowing, the power supply to the water heater or powered anode system is disconnected.

Check the power supply or wire connections to the powered anode control.

If the control is flashing red, then there is a malfunction with the powered anode system. Make sure there are no bare spots

in the wire insulation to the powered anode rods. Check all electrical connections. The powered anode rods are insulated

from the water heater tank in the bushing. With an ohmmeter, check continuity between the powered anode terminal and

the bushing. There should not be continuity. If there is continuity, replace the powered anode assembly.
