The upper and lower thermostats are adjustable if a different

water temperature is desired. Read all warnings in the

Temperature-Regulation section before proceeding.

1. Turn “OFF” the electric power to the water heater at the

junction box.

2. Take off the upper and/or lower access panel(s), then fold the

insulation back to expose the thermostat.

3. The slotted adjustment can be turned clockwise (

) with

a screwdriver to increase the temperature setting or counter

clockwise (

) to decrease the temperature setting.

4. Replace the insulation and access panel.

5. Turn “ON” the power supply.

Anode Rod Inspection

Each water heater contains at least one anode rod, which will

slowly deplete (due to electrolysis) prolonging the life of the

water heater by protecting the glass-lined tank from corrosion.

Adverse water quality, hotter water temperatures, high hot

water usage, hydronic heating devices, and water softening

methods can increase the rate of anode rod depletion. Once

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

eventually developing a leak.

Certain water conditions will cause a reaction between the

anode rod and the water. The most common complaint

associated with the anode rod is a “rotten egg smell” produced

from the presence of hydrogen sulﬁ de gas dissolved in

the water. IMPORTANT: Do not remove this anode rod

permanently as it will void any warranties. A special anode rod

may be available if water odor or discoloration occurs.

NOTE: This anode rod may reduce but not eliminate water

odor problems. The water supply system may require special

ﬁ ltration equipment from a water conditioning company to

successfully eliminate all water odor problems.

Artiﬁ cially softened water is exceedingly corrosive because the

process substitutes sodium ions for magnesium and calcium

ions.

The anode rod should be inspected after a maximum of three

years and annually thereafter until the condition of the anode

rod dictates its replacement. NOTE: Artiﬁ cially softened water

requires the anode rod to be inspected annually.

The following are typical (but not all) signs of a depleted

anode rod:

• The majority of the anode rod’s diameter is less than 3/8”.

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

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

FIGURE 15.

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.

In replacing the anode:

1. Turn off power 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 “Draining and Flushing” for proper procedures). Close

drain valve.

4. Remove old anode rod.

5. Use Teﬂ on® tape or approved pipe sealant on threads

and install new anode rod.

6. Turn on water supply and open a 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 in this manual. See

the Repair Parts Illustration for anode rod location.
