To Remove The Anode Rod; To Install The Anode Rod - John Wood POWER VENTED GAS FIRED WATER HEATER Installation And Operating Instructions Manual

•
Significant sections of the support wire (approx. 1/3 or
more of the anode rod's length) are visible.
If the anode rod show signs of either or both it should be
replaced.
Note: Whether re-installing or replacing the anode rod, check
for any leaks and immediately correct if found.

To Remove the Anode Rod

1. Set the gas control valve/thermostat to its lowest setting
by turning the knob counter-clockwise to the VAC point
(Figure 35).
2. Turn gas control switch to the "OFF" position and turn
"OFF" the gas supply to the unit (Figure 35).
3. Disconnect the electrical power to the water heater from
the wall outlet.
4. Shut off the incoming water supply to the water heater
and open a nearby hot-water faucet to depressurize the
water tank.
5. 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.
6. Remove the anode cap on top of the heater and remove
just enough insulation so you can access to the anode
head (Figure 39). Keep in a safe place for reinstallation
later.
7. Remove the anode rod by using a ratchet and a 1-1/16"
socket turning counter-clockwise (Figure 39).

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
CAP
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 electrical power to the water heater in the
wall outlet and turn the gas supply back "ON" to the gas
control valve/thermostat.
7. Turn the gas control switch to the "ON" position (Figure
35).
8. To restart the water heater, follow the directions on the
"Lighting and Operating Instructions" label located on the
front of the water heater near the gas control valve/ther-
mostat.
