Operating Instructions

Water Heater Capacity and Increasing Temperature
Setpoint (For Water Heaters without an Integrated
Mixing Valve):

The water heater temperature setting strongly impacts
the amount of usable hot water available for showers
and baths.

• Energy consumption/savings and efficiency testing of
water heaters is performed according to Department
of Energy (DOE) requirements specified at the date of
manufacture.

• Safety regulations require a factory setting no greater
than 125°F (52°C) for all new water heaters. Therefore,
if your old water heater was set to a hotter temperature
than your new water heater with a factory set setpoint of
120°F (49°C), the new water heater may seem to provide
lower capacity than your old water heater. This can be
corrected by increasing the temperature setpoint.

• If more hot water capacity is desired, increasing the
temperature from 120°F to 135°F (49°C to 57°C) will

OPERATING INSTRUCTIONS

enable the same tank of hot water to last about 25%
longer because less hot water is mixed in at the shower
or faucet.

• Increasing the water temperature setpoint may improve
the cleaning performance of dishwashers and washing
machines.

• The user can adjust the temperature setting to meet
their needs. Always read and understand the safety
instructions contained in the owner’s manual before

adjusting the temperature setpoint.

Mixing Valves

• For models with an integrated electronic mixing valve,
hot water capacity can be increased by changing
capacity selection from control, while maintaining
outlet water temperature. See page 8 for instructions
to increase hot water capacity.

• If your model does not include an integrated Electronic
mixing valve: a supplimental mixing valve for reducing
point-of-use water temperature by mixing hot and cold
water in branch water lines are commercially available.
Contact a licensed plumber or the local plumbing
authority for further information.

Extended Shutdown Periods

If the water heater is to remain idle for an extended
period of time, the power and water to the appliance
should be turned off and the water heater drained to
conserve energy and prevent a buildup of dangerous
hydrogen gas. This unit has no power button, power
can only be shut off at the circuit breaker or disconnect
switch.

The water heater and piping should be drained if they
might be subjected to freezing temperatures.

After a long shutdown period, the water heater’s
operation and controls should be checked by qualified
service personnel. Make certain the water heater is
completely filled again before placing it in operation.

NOTE: Refer to the Hydrogen Gas Caution in the
Operating Instructions (see page 3).

Routine Preventive Maintenance

DANGER

operating the relief valve, make certain no one will
be exposed to the danger of coming in contact with
the hot water released by the valve. The water may
be hot enough to create a scald hazard. The water
should be released into a suitable drain to prevent
injury or property damage.

NOTE: If the temperature and pressure-relief valve
on the hot water heater discharges periodically, this

CARE AND CLEANING

may be due to thermal expansion in a closed water
system. Contact the water supplier or your plumbing
contractor on how to correct this. Do not plug the
relief valve outlet.

Properly maintained, your water heater will provide years
of dependable trouble-free service. It is suggested that
the following annual preventive maintenance program be
established.

1. Inspect Temperature & Pressure Relief Valve.

2. Inspect heating elements, ECO, and wiring to each.

3. Drain and Flush the water heater tank.

4. Anode rod must be removed and inspected.

Risk of Scald - Before manually

Temperature and Pressure-Relief Valve:

Once a year, it is recommended to lift and release the
lever handle on the temperature and pressure-relief
valve, located on the front-right side of the water heater,
to make certain the valve operates freely. Allow several
gallons to flush through the discharge line to an open
drain.

Draining and Flushing the Water Heater

CAUTION

the water heater before draining water.

DANGER

operating the relief valve, make certain no one will
be exposed to the hot water released by the valve.
The water drained from the tank may be hot enough
to present a scald hazard and should be directed to
a suitable drain to prevent injury or damage.

A water heater’s tank can act as a settling basin for
solids suspended in the water. It is therefore not
uncommon for hard water deposits to accumulate in the
bottom of the tank. To clean the tank of these deposits,
it is recommended to drain and flush the water heater
tank once a year. To drain the water heater, follow these
steps:

1. Turn off power to the unit. The electric heating
elements will become damaged if operated without
water.

2. Attach a garden hose to the drain valve located at the
bottom of the unit and direct that hose to a drain.

3. Turn off the cold water supply.

4. Admit air to the tank by opening a hot water faucet or
lifting the handle on the relief valve.

5. Open the drain valve.

Use a flat blade screwdriver
to turn brass drain valve or an
adjustable open-end wrench to
turn black stem on plastic drain
valve.

Straight Brass
Drain Valve

Heating Elements and ECO:

Once a year, it is recommended to inspect the heating
elements, ECO, and wiring to each. Inspection should
be completed by service personnel qualified in electrical
appliance repair.

Most electrical appliances, even when new, make some
sound when in operation. If the hissing or singing sound
level increases excessively, the electric heating element
may require cleaning. Contact a qualified installer or
plumber for inspection.

Flushing the Tank:

1. Follow steps above to drain the water heater.

2. Once the water heater is empty, with the drain valve
open and garden hose attached to the drain valve,
turn on the cold water supply.

3. Allow several gallons to flush through the drain valve
and hose to an open drain.

4. Turn off the water supply and allow any water
remaining in the tank to drain.

5. Repeat steps 3 and 4 until water runs clear.

6. Close the drain valve and fill the tank before returning
power to the unit. The tank is full when water runs out
of a nearby open hot water faucet.

Flushing should be done with an empty tank to promote
additional removal of sediment.

Care and Cleaning

Routine Preventative Maintenance
Anode Rod

CARE AND CLEANING

Anode rods are designed and installed to protect and
extend the life of residential water storage tanks.

The anode rod must be removed from the water heater’s
tank and inspected annually, and replaced when more
than 6” (15.2 cm) of core wire is exposed at either end of
the rod.* NOTE: Artificially softened water will cause the
anode rod to consume more rapidly.

Due to shock hazard and to prevent accidental water
leaks, this inspection should be done by a qualified
servicer or plumber, and requires that the electric power
and cold water supply be turned off before servicing the
anode rod.

NOTICE: Do not remove the anode rod from the water
heater’s tank except for inspection and/or replacement,
as operation with the anode rod removed will shorten
the life of the glass-lined tank and will void warranty
coverage.

Some areas have water conditions that may cause
an odor to develop in the water heater. Special alloy
replacement rods are available to address this condition.

*NOTE: Failure to replace the anode rod when
consumed voids the warranty for the tank. Warranty
coverage for all other components remains intact,
and is unaffected by this maintenance requirement.
The replacement anode rod, and the inspection for
consumption are not covered by warranty.

Additional information for models with an anode
depletion sensing feature (Anode button on the control,
on equipped models):

When the depletion-sensing anode rod nears end of life,
the ANODE text will illuminate and the control will beep
and display F70. When this occurs, the anode rod must
be inspected and replaced if the core wire at the top of
the anode rod is exposed.* It is recommended to replace
the anode rod as soon as possible to ensure that the tank
will continue to be protected from corrosion. Call installer/
servicer to order or to replace the anode rod. (See page 12
for instructions to change the anode rod.)

Press the ANODE button once to silence the alarm. Once
replaced, reset the alarm by pressing and holding the
ANODE button for 5 seconds until the control beeps and the
Anode Light will turn off.

If special alloy anode rod is installed to address a water
odor condition, the anode depletion sensing feature must
be disabled. If disabled, annual inspections of the anode
rod are required since the water heater will no longer be
capable of alerting for a depleted anode rod.

To disable the feature:

1. Upon power-up following a special alloy anode rod
installation, the control will sound an alarm and F41 will
display. Press the ANODE button to quiet the alarm.

2. Press the ANODE button 3 times. “Off” or “On” will
display confirming that the feature has been disabled/
enabled.

To enable the feature if a new anode depletion sensing
anode rod is installed, follow Step 2 above.

Note: If the display is blank, press any button to wake the
control before entering a button combination.

NOTE: If the water heater has been installed with a
device that periodically cuts power to the water heater, the
accuracy of the anode rod depletion sensing feature may
become compromised and anode rod inspection every 2-3
years is required.

If the water heater will be inactive for a long period of time
and the water heater cannot be drained, it is recommended
to leave the power turned on with the water heater in
vacation mode to ensure that the feature will continue to
operate properly while still conserving energy.

NOTE: Refer to the Hydrogen Gas Caution in the
Operating Instructions (see page 3).

practical to the area of greatest heated water demand.
Long uninsulated hot water lines can waste energy
and water. Unit must be installed in a level location.
If required, add shims under base of unit to level for
proper operation.

NOTE: This unit is designed for any common indoor
installation.

Servicing the water heater requires proper installation
such that front panels can be removed to permit
inspection and servicing. Reference installation
instructions found in this manual.

Moving the water heater or other appliances to provide
service to the water heater is not covered under
warranty.

CAUTION

The water heater should not be located in an
area where leakage of the tank or connections
will result in damage to the area adjacent to it
or to lower floors of the structure. Where such
areas cannot be avoided, it is recommended
that a suitable catch pan, adequately drained, be
installed under the water heater.

Risk of Property Damage -

LOCATION (Cont).

Required clearances:

There must be sufficient clearance between any
object and the top, rear and sides of the water
heater in the event service is needed. The controls
and drain at front of unit must have clear access
for operation and service. Installations that require
minimal clearance on the sides or rear of the water
heater for earthquake straps are also acceptable.

In these cases, additional clearance should be
provided on the opposite side of the unit to
allow for service access. Integrated electronic
mixing valve models should not be installed
with pre-heated water from solar or other heated
sources (higher than intended user set point).

CATCH PAN INSTALLATION

(If required)

Relief Valve
Drain Line

Catch Pan

Catch Pan
Drain (piped to
suitable drain)

NOTE: Auxiliary catch pan MUST conform to local
codes. Catch Pan Kits are available from the store
where the water heater was purchased, a builder
store or any water heater distributor. The catch
pan should be 2” (5.1 cm) minimum larger than the
Water Heater base diameter. To prevent corrosion
and improve Drain Valve access it is recommended
that the water heater be placed on spacers inside
the catch pan.

THERMAL EXPANSION

If a check valve is present on the inlet water line,
it will create a “closed system.” Heating water in
a closed system creates an increase in pressure
within the water system because the pressure is not
able to dissipate in the main supply line. Referred to
as “thermal expansion”, the rapid pressure increase
can cause the relief valve to operate (releasing
water) during each heating cycle, potentially causing
premature failure to the valve or even the water
heater. The suggested method of controlling thermal
expansion is to install an expansion tank in the cold
water line between the water heater and the check
valve as shown in the following illustrations. Contact
your installing contractor, water supplier, or plumbing
inspector for additional information.

Installation Instructions

WATER SUPPLY CONNECTIONS

Refer to the illustration below for recommended installation. The HOT and COLD water connections are clearly
marked and are ¾” NPT on all models. When connecting to the inlet/outlet ports, the use of ¾” female NPT
tapered thread fittings with use of thread sealant is recommended. The installation of unions is recommended
on the hot and cold water
connections so that the
water heater may be easily
disconnected for servicing if
necessary. Piping should be
routed to allow anode rod
removal.

NOTE: Install a shut-off valve
in the cold water line near the
water heater. This will enable
easier service or maintenance
of the unit later.

IMPORTANT: Do not apply
heat to the HOT or COLD
water connections. If sweat
connections are used, sweat
tubing to adapter before
fitting the adapter to the cold
water connections on heater.
Any heat applied to the hot
or cold water connection
will permanently damage
the internal plastic lining in
these ports.

Install a vacuum relief valve
and/or anti-siphon device when
required by local jurisdictions.

RELIEF VALVE

WARNING

pressure rating of the relief valve must not
exceed 150 PSI (1.03 MPa), the maximum working
pressure of the water heater as marked on the
rating plate.

A new combination temperature and pressure-relief
valve, complying with the Standard for Relief Valves
and Automatic Gas Shut-Off Devices for Hot Water
Supply Systems, ANSI Z21.22, is supplied and must
remain installed in the opening provided and marked
for this purpose on the water heater. No valve of any
type should be installed between the relief valve and
the tank. Local codes shall govern the installation of
relief valves.

The BTUH rating of the relief valve must not be less
than the input rating of the water heater as indicated
on the rating label located on the front of the heater
(1 watt=3.412 BTUH).

Connect the outlet of the relief valve to a suitable
open drain so that the discharge water cannot contact

INSTALLATION INSTRUCTIONS

live electrical parts or persons and to eliminate
potential water damage.

Piping used should be of a type approved for hot
water distribution. The discharge line must be no
smaller than the outlet of the valve and must pitch
downward from the valve to allow complete drainage
(by gravity) of the relief valve and discharge line. The
end of the discharge line should not be threaded or
concealed and should be protected from freezing.
No valve of any type, restriction or reducer coupling
should be installed in the discharge line.

Risk of Unit Damage - The

Relief Valve
Insulation

CAUTION

To reduce the risk of excessive pressures and
temperatures in this water heater, install temperature
and pressure protective equipment required by local
codes and no less than a combination temperature
and pressure relief valve certified by a nationally
recognized testing laboratory that maintains periodic
inspection of production of listed equipment or
materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot
Water Supply Systems, ANSI Z21.22. This valve
must be marked with a maximum set pressure not
to exceed the marked maximum working pressure
of the water heater. Install the valve into an opening
provided and marked for this purpose in the water
heater, and orient it or provide tubing so that any
discharge from the valve exits only within 6 inches
above, or at any distance below, the structural floor,
and does not contact any live electrical part. The
discharge opening must not be blocked or reduced in
size under any circumstances.

TO FILL THE WATER HEATER

WARNING

tank must be full of water before heater is turned
on. The water heater warranty does not cover
damage or failure resulting from operation with
an empty or partially empty tank.

Make certain the drain valve is completely closed.
Open the shut-off valve in the cold water supply line.
Open each hot water faucet slowly to allow the air to

vent from the water heater and piping.
A steady flow of water from the hot water faucet(s)

indicates a full water heater.
Condensation can form on the tank and fittings when

it is first filled with water. Condensation may also
occur with a heavy water draw and very cold inlet
water temperature.

This condition is not unusual and will disappear once
water is heated. If condition persists, examine fittings
for potential leaks and repair, as required.

• The odor can be reduced or eliminated in most water heaters by replacing
the anode rod with less-active material rod. In some cases, an added
step of chlorinating the water heater and all hot water lines may be
necessary, contact your local water professional or plumber for options and
instructions.
Go to GEAppliances.com/waterheater for information on purchasing
this replacement anode rod. A qualified servicer or plumber should do
this replacement. Use of a non-GE Appliances approved anode rod, or
operating the water heater without a GE Appliances approved anode rod
will VOID the warranty.

• In certain cases, increasing the tank temperature to 140°F (60°C) can
reduce this odor issue. Reference the Water Temperature Adjustment
section of the Important Safety Information of this manual for procedure and
dangers of scalding water. Installation of temperature limiting valves can be
used to reduce risk of scalding.
