WARNING

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. Turn off water supply to water heater. Rotate knob of gas control to “OFF” position.

For Honeywell Control, rotate knob counter-clockwise to the “OFF” position.

Step 2. Turn off cold water supply to heater. Connect hose to drain spigot of water heater and route to an open drain. Open a nearby hot water faucet to vent heater for draining. Open drain spigot of hot water heater and allow heater to drain to a point below the outlet connection nipple.

Step 3. Disconnect outlet nipple from plumbing system.

Step 4 With an appropriate wrench, remove outlet nipple/anode from the water heater. Use caution not to damage pipe threads.

Step 5. Visually Inspect outlet nipple/anode. Outlet nipple/anode should show signs of depletion, this is normal.

If depletion is ½ of the original anode diameter (approximately 5/8” diameter), replacement is recommended. If any of thesteel core of the anode is exposed, replacement is recommended.

Step 6. Upon completion of inspection or subsequent replacement, reinstall outlet nipple/anode into heater. Connect nipple to plumbing system, resume water supply and refill heater with water.
