Anode Replacement Procedure
1. Position main power switch to OFF.
2. Disconnect (unplug) water heater from 120 volt
power source.
3. Turn OFF water supply and drain the water
heater.
4. Locate (see image below) and remove anode rods from heater (1-1/16 hex socket).
5. Visually inspect anode rod. Anode rod should show signs of depletion, this is normal. If the depletion is 1/2
of the original diameter (approximately 3/4" diameter), replacement is recommended. If any of the steel core
of the anode is exposed, replacement is recommended.
6. Upon completion of inspection or subsequent replacement, apply thread sealing tape or other thread
compound to threads of anode and reinstall into heater. Restore the water supply and check for and repair
any leaks found.
