Powered Anode Operation
To protect the glass-lined water tank from corrosion 
through electrolysis, this water heater is equipped with a 
non sacrificial powered anode rod. The powered anode 
rod is non sacrificial and should not need to be replaced 
unless damaged.
If the powered anode rod has been damaged then the 
powered anode rod should be removed and replaced 
from the water heater tank. IMPORTANT: If the damaged 
powered anode rod has not been replaced but has been 
remove permanently, this will void any warranties. 

NOTE: Whether re-installing or replacing the powered 
anode rod, check for any leaks and immediately correct if 
found.

In replacing the power anode:
1.  Turn off electrical supply and gas supply to the water 

heater.

2.  Shut off the water supply and open a nearby hot water 

faucet to depressurize the water tank.

3.  Drain approximately 5 gallons of water from tank 

(Refer to the “Draining and Flushing” section for proper 
procedures). Close drain valve.

4.  Remove the wiring connection on the top of the 

powered anode rod and remove the old powered 
anode rod (Figure 22).

5. Use 

Teflon

®

 tape or approved pipe sealant on threads 

and install new anode rod.

6.  Turn on water supply and open nearby hot water faucet 

to purge air from water system. Check for any leaks 
and immediately correct any if found.

7.  Turn on electrical and gas supplies. Restart the water 

heater as directed under the “Operating Your Water 
Heater.” See the “Repair Parts Illustration” section for 
anode rod location.

It is recommended that the tank be drained and flushed 

every 6 months to remove sediment which may build up 

during operation. The water heater should be drained if 

being shut down during freezing temperatures. To drain the 

tank, perform the following steps:
1.  Turn off the gas to the water heater at the manual gas 

shut-off valve and turn off the electrical power to the 

gas control/thermostat valve.

2.  Open a nearby hot water faucet until the water is not 

longer hot.

3.  Close the cold water inlet valve.
4.  Connect a hose to the drain valve and terminate it to 

an adequate drain or external to the building.

5.  Open the water heater drain valve and allow all the 

water to drain from the tank. Flush the tank with water 

as needed to remove sediment.

6.  Close the drain valve, refill the tank, and restart the 

heater as directed in this manual.

If the water heater is going to be shut down for an 

extended period, the drain valve should be left open.
IMPORTANT: Condensation may occur when refilling the 

tank and should not be confused with a tank leak.

At least annually, a visual inspection should be made of 

the venting and air supply system, piping systems, and 

main burner. Check the water heater for the following:
• 

Obstructions, damage, or deterioration in the venting 

system. Make sure the ventilation and combustion air 

supplies are not obstructed. 

• 

Clean any dust or debris from the louvers of the air 

intake chamber.

• 

Soot and/or carbon on the main burner. Contact a 

qualified technician.

• 

Leaking or damaged water and gas piping.

• 

Presence of flammable or corrosive materials in the 

installation area.

• 

Presence of combustible materials near the water 

heater.

• 

After servicing this water heater, check to make sure 

it is working properly. (See “Operating Your Water 

Heater” section of this manual.)

IMPORTANT: If you lack the necessary skills required to 

properly perform this visual inspection, you should not 

proceed, but get help from a qualified technician.
