ANODE ROD MAINTENANCE
Note:
Whether re-installing or replacing the anode rod,
check for any leaks and immediately correct if found.
To Remove the Anode Rod
Note: The White-Rodgers Intelli-VentTM gas control/
thermostat does not have a gas control switch.
1. Disconnect the water heater from the electrical
power at the wall outlet (all gas control/thermostat
models).
2. Shut off the incoming water supply to the water
heater and open a nearby hot water faucet to
depressurize the water tank.
3. Connect a hose to the drain valve and terminate it
to adequate drain or to the exterior of the building.
Open the drain valve and allow at least 5 gallons
of water from the tank to drain. Close drain and
remove hose.
4. Remove the anode cap on top of the heater
and remove just enough insulation so you can
access the anode head. Keep in a safe place for
reinstallation later.
5. Remove the anode rod by using a ratchet and a
1-1/16” socket turning counter-clockwise.
To Remove a Combination Heat Trap
Nipple/Anode (on some models)
1.
Follow steps 1 through 3 above on “How to Remove
the Anode Rod”.
2. Locate the Combination Heat Trap Nipple/Anode
installed in the hot water side of the unit. Disconnect
the hot water piping from the unit. Using a pipe
wrench, turn the nipple anode counter-clockwise to
remove.
To Install the Anode Rod
1.
Use Teflon® tape or an approved pipe sealant on
threads of the new anode rod.
2. Place the anode rod in the spud (top of the tank)
and turn clockwise until the threads are hand tight.
Using a ratchet and 1-1/16” socket tighten down
water tight.
3. Open a nearby hot water faucet to purge air from
the water line. Fill water heater tank completely
(Note: To assure the water heater tank is full, keep
the hot water faucet open for 3 minutes after a
constant flow of water is obtained).
4. After turning off the hot water faucet, check for water
leaks around anode rod and immediately correct any
if found.
5. Reinstall the insulation and anode cap which were
removed in step 6 above.
6. Reconnect the water heater to the electrical power
at the wall outlet and turn “ON” the gas supply to the
gas control/thermostat.
Note: The White-Rodgers Intelli-VentTM gas control/
thermostat does not have a gas control switch.
7. To restart the water heater, follow the directions on
the “Lighting and Operating Instructions” label
To Install a Combination Heat Trap Nipple/
Anode (on some models)
1.
