Water Heater components may be HOT when performing the following steps in this
procedure. Take necessary precaution to prevent personal injury.
Step 1. Disconnect (unplug) water heater from electrical supply.
Step 2. Turn “OFF” water supply to water heater.
Step 3. Open a near by hot water faucet to relieve tank pressure.
Step 4. Connect hose to drain valve of water heater and route to an open drain. Open

Close drain valve and disconnect drain hose from water heater.
Step 5. If required, disconnect top plumbing connection from top of water heater.

and remove jacket head from top of water heater. Note, it may
be necessary to use a screw driver to pry underneath
jacket head (see photos at right).
Step 7. Remove insulation from top of water heater to expose collector cover,
if necessary. (see bottom of page for approx. anode locations)
Step 8. Remove screws from top (or sides) of collector cover. Note, it may be
necessary to chisel away some foam to access screws.

the steel core of the anode is exposed, replacement is recommended.
Step 11. Upon completion of inspection or subsequent replacement,
reinstall anode rods into water heater.
