Anode Inspection & Replacement
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.
Disconnect the outlet nipple from the plumbing system.
Step
4.
With an appropriate tool such as a pipe wrench, remove the outlet
nipple/anode from the water heater. Use caution not to damage the pipe
threads.
Step
5.
Visually inspect the outlet nipple/anode. The outlet nipple/anode should show
signs of depletion, this is normal. If depletion is ½ of the original anode
diameter (approximately ¾” diameter), replacement is recommended. If any of
the steel core of the anode is exposed, replacement is recommended.
Step
6.
Upon completion of inspection or subsequent replacement, reinstall the outlet
nipple/anode into the water heater. Connect the nipple to the plumbing
system, resume water supply and refill with water.
Step
7.
To resume operation, follow the instructions located on the lighting instruction
label or the lighting instructions located in the installation and operation
manual.
WARNING
Water Heater components and stored water may be HOT when performing the
