Anode Inspection and Replacement
Step 1. Position the gas control knob to
the “OFF” position
.
Step 2. Turn off the cold water supply to the water heater.
Step 3. Connect a hose to the drain valve of the water heater and route it to an open drain.
Step 4. Open a nearby hot water faucet to vent the water heater for draining.
Step 5. Open the drain valve of the water heater and allow the water heater to drain to a
point below the outlet connection nipple.
Step 6. Disconnect the outlet nipple from the plumbing system.
Step 7. With an appropriate tool, such as a pipe wrench, remove the outlet nipple/anode
from the water heater. Use caution to not damage the pipe threads.
Step 8. Visually inspect the outlet nipple/anode. The outlet nipple/anode should show signs
of depletion; this is normal. If the depletion is 1/2 of the original anode diameter
(approximately 3/4
” diameter), replacement is recommended. If any of the steel core
of the anode is exposed, replacement is recommended.
Step 9. Upon completion of inspection or subsequent replacement, re-install the inlet
nipple/diptube into the water heater.
Ensure pipe dope is used on the nipple’s
threads. Connect the nipple/diptube to the plumbing system and resume the water
supply to refill with water.
Step 10. To resume operation, follow the instructions located on the lighting instruction label
or the lighting instructions located in the Installation and Operation Manual.
