4 • Powered Anode System
INSTALLATION
FOLLOW ALL SAFETY NOTICES IN YOUR
WATER HEATER’S MANUAL.
WARNING
Electric Shock Risk
Contact with electrical
components can result in
severe injury or death from
electrical shock.
• Ensure that power to the control
module is disconnected before
installing or servicing the Powered
Anode System.
• Electric water heaters only:
Disconnect power to the water
heater by opening the circuit
breaker(s) before installing or
servicing. Use a non-contact circuit
tester to confirm that power is off
before installation or service.
WARNING
GAS WATER HEATERS:
Fire & Explosion Risk
Shut off the main gas supply
before servicing the water
heater. Failure to do so can result in
severe injury or death.
Kit Components:
• Control Module with two self-tapping
screws
• Anode (Electrode)
• Power Supply (Input 120 VAC/
Output to module: 12 VDC)
• Wiring Harness
Tools and Supplies Required:
• 1-1/16” deep-well socket
• Air compressor (if an air impact
wrench is used)
• Electric or air impact wrench
• Screwdriver or nut driver (to loosen/
ghten screw on water heater jacket
• Water Hose
1
Shut off the electric
power and/or gas
supply to your water heater.
Refer to the shutdown instruc ons in
your water heater’s manual.

Drain the water
heater according to
these steps:
A. Turn off the cold water supply to the
water heater.
B. Open hot water faucets to relieve the
water pressure.
C. Attach a water hose to the drain valve.
Run the hose to a drain or outdoors.
D. Open the drain valve and drain about
five gallons of water from the water
heater. (Water inside the heater
will help hold the unit steady while
removing the anode rod.)
E. Close the water heater drain valve,
then close the hot water faucets.

Remove the old
anode rod.
A. Locate the anode rod’s hex head on
top of the water heater.
B. Loosen the hex head with a quick
burst from the impact wrench
(1-1/16” socket).
C. Unscrew the anode by hand once it is
loose. (This prevents tank damage.)

Install the new anode
from your kit:
A. Insert the new anode into the anode
opening and start screwing it in by
hand (clockwise).
NOTICE:
• DO NOT use pipe dope or thread
sealing tape on the anode’s
threads. It has sealant on the
threads already.
• During the next step, use a deep
well socket only. Doing so will
prevent damage to the anode’s
fl ag
terminal.
B. Tighten the anode with a deep well
1-1/16” socket until tight.
