Anode Rod/Water Odor

Each water heater contains at least one anode rod, which

will slowly deplete while protecting the glass-lined tank

from corrosion and prolonging the life of the water heater.

Once the anode is depleted, the tank will start to corrode,

eventually developing a leak. Certain water conditions will

cause a reaction between this rod and the water. The

most common complaint associated with the anode rod

is a “rotten egg smell” produced from the presence of

hydrogen sulfide gas dissolved in the water. IMPORTANT:

Do not remove this rod permanently as it will void any

warranties. The parts list includes a special anode that

can be ordered if water odor or discoloration occurs.

NOTE: This rod may reduce but not eliminate water

odor problems. The water supply system may require

special aeration or chlorination equipment from a water

conditioning company to successfully eliminate all water

odor problems.

The use of a water softener may decrease the life of the

water heater tank.

The anode rod should be removed from the water heater

tank every 3 years for inspection. The following are typical

(but not all) signs of a depleted anode rod:

• The majority of the rods diameter is less than 3/8”.

• Significant sections of the support wire (approx. 1/3 or

more of the anode rod’s length) are visible.

If the anode rod shows signs of either or both it should be

replaced. NOTE: Whether reinstalling or replacing the

anode rod, check for any leaks and immediately correct if

found.

In replacing the anode:

1. Turn off 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 old anode rod.

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. Restart the water heater as directed under the

“Operating Your Water Heater.” See the “Repair Parts

Illustration” section for anode rod location.

Draining and Flushing

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.

1. Move the switch on the gas control valve/thermostat to the

“OFF” position to turn off the water heater.

2. Open a nearby hot water faucet until the water is no 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 of 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.

Routine Preventive Maintenance

At least annually, a visual inspection should be made of

the venting and air supply system, piping systems, main

burner, pilot burner, and flame-arrestor. 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 base-ring filter.

• Soot and/or carbon on the main burner and pilot

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.
