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.

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.  

Water heater components and stored water may be HOT when performing the following steps in this procedure.  Take
necessary precaution to prevent personal injury.
