ANODE INSPECTION AND REPLACEMENT

This water heater is equipped with multiple sacrificial anodes. Anodes protect the glass-lined tank from corrosion by sacrificing themselves through electrolysis. When the anode material is consumed, there is no more protection and corrosion of the tank accelerates.

Inspection of the anode every 6 months allows you to identify the rate of anode degradation. The anode should be replaced when its diameter is 3/8 of an inch, or annually which ever is first. Aggressive, very hot and softened water causes rapid consumption of the anode requiring frequent inspections. The replacement anodes rods are available from your Bradford White distributor.

To inspect or replace an anode:

The anodes on this water heater are easily accessible from the top of the water heater making replacement simple and quick. Use the following procedure to remove and inspect the anodes.

1.Drain the heater. Refer to DRAINING THE WATER HEATER instructions in this section.

2.Flush the heater. Refer to FLUSHING THE WATER HEATER instructions in this section.

3.Remove the combustion surround top by unlatching.

4.Remove the second pass access cover. (If equipped)

8.Inspect and replace the anode as required. Use pipe tape or sealant when reinstalling the anode.

9.Close the drain valve. Open a hot water fixture to allow air to escape. Open the cold water supply to water heater and allow the tank to fill. Follow the lighting instructions.
