be free of cracks and any blockage. Hydro-jet slots should be open and free of any
blockage. Any damage, such as cracks, restriction due to deformation, or uninten-
tional holes are not field repairable and the inlet nipple/diptube must be replaced.
Step 7. Upon completion of the inspection or subsequent replacement, reinstall
the inlet nipple/diptube into the water heater. Connect the nipple to the plumbing
system, resume water supply to the water heater, and refill the water heater.
Step 8. To resume operation, follow the instructions located on the water heater
lighting instruction label. Or, use the lighting instructions located in the water heater
installation and operating manual.
Anode Inspection and Replacement
Step 1. Move the gas control power switch to the “OFF” position
Step 2. Unplug the water heater from the wall outlet.
Step 3. 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 water heater and
allow the water heater to drain to a point below the outlet connection nipple.
Step 4. Disconnect the outlet nipple from the plumbing system.
Step 5. With an appropriate tool, such as a pipe wrench, remove the outlet nip-
ple/anode from the water heater. Use caution not to damage the pipe threads.
Step 6. Visually inspect the outlet nipple/anode. The outlet nipple/anode should
show signs of depletion, which is normal. If depletion is one-half 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 7. Upon completion of the inspection or subsequent replacement, reinstall
the outlet nipple/anode into the water heater. Connect the nipple to the plumbing
system, resume water supply to the water heater, and refill the water heater.
