Anode inspection and replacement

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).

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.

instructions on the lighting instruction label or the lighting instruction located in the
installation and operating instruction manual.
