Anode Inspection & Replacement
Water Heater components and stored water may be HOT when performing the
following steps in this procedure. Take necessary precaution to prevent
personal injury.
Step 1.
Position the gas control knob in 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 not to 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 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 9.
Upon completion of the inspection or subsequent replacement, re-install outlet
nipple/anode into the water heater. Ensure pipe dope is used on the nipple's
threads. Connect the nipple to the plumbing system, resume water supply and
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.
