Anode Inspection & Replacement
This water heater has 2 anodes installed. Both anodes require inspection.
Step 1.
Position the on/off switch of the gas control valve to the "OFF" position and
unplug the water heater from the wall outlet.
Step 2.
Turn off the cold water supply to the water heater. Connect a hose to the drain
valve of the water heater and route to an open drain. Open a nearby hot water
faucet to vent the water heater for draining. Open the drain valve of the water
heater and allow the water heater to drain to a point below the outlet
connection nipple.
Step 3.
Remove the caps with a slotted
screwdriver or similar tool.
Step 4.
Remove the insulation to gain
access to the hex head anode.
Step 5.
The hex head anode is approximately 4-1/4" below the
jacket head. An extension and a deep 1-1/16" socket is
necessary to loosen the anode.
Step 6.
Remove the anode and visually inspect the anode.
Step 7.
If the anode does show signs of depletion, this is normal.
a. If depletion is ½ of the original anode diameter
(approximately ¾" diameter), replacement is
recommended.
b. If any of the steel core of the anode is exposed,
replacement is recommended.
Step 8.
Upon completion of inspection or subsequent replacement, apply plumber's
tape to the threads and reinstall the hex head anode into the water heater. Put
in place the insulation as best as possible to reduce heat loss and reapply the
hole closure.
Step 9.
Repeat steps 4 through 8 for the second anode.
Step 10. Resume the water supply and refill with water.
Step 11. To resume operation, follow the instructions located on the lighting instruction
label or the lighting instructions located in the Installation and Operation
manual.
