Anode inspection and replacement
Step 1. Turn off water supply and drain water heater.
Step 2. Disassemble water heater per “Disassembly Procedure for Access to Andoes & Flue Baffles”.
Step 3. Locate and remove anode rods from heater (1-1/16 hex socket).
Step 4. Visually inspect anode rod. Anode rod should show signs of depletion, this is normal. If
the depletion is ½ of the original diameter (approximately ¾" diameter), replacement is
recommended. If any of the steel core of the anode is exposed, replacement is
recommended.
Step 5. Upon completion of inspection or subsequent replacement, apply thread sealing tape or other
thread compound to threads of anode and reinstall into heater. Restore water supply
and check for and repair any leaks found.
Step 6. Reinstall collector cover per “Collector Cover Installation Procedure”.
Step 7. Reinstall collector insulation and control panel, reconnect control panel wire harnesses.
Step 8. Restore 120 volts to water heater and verify proper heater operation following the
instructions on the lighting instruction label or the lighting instruction located in the
installation and operating instruction manual.
Step 9. Replace surround cover on top of water heater.
