12.6 Changing the anode rod

A magnesium anode is used to extend the life of the
tank. Permanent removal of this anode for any reason
will void the warranty.
Depending on conditions, the magnesium anode rod
may need to be changed approximately every two years.
Galvanic and electrolytic corrosion can destroy a tank
with a spent anode rod. Rusty water is usually an indi-
cator of a spent anode rod.
1. Unplug and drain the water heater (See 12.1,
"Draining the water heater", pg. 9).
2. Remove the cover (See 12.2, "Removing the
cover", pg. 9).
3. Remove the heating element (See 12.3, "Remov-
ing the heating element", pg. 9).
4. Remove the anode rod from the dismounted
heating element holder by unscrewing.
5. Fit a new anode rod into the heating element
holder.
