Lighting and Shutdown
OPERATING INSTRUCTIONS
Extended Shutdown Periods
If the water heater will not be in use for an extended
period of time, the appliance’s gas and water should
be turned off and the water heater drained to conserve
energy and prevent a buildup of dangerous hydrogen gas.
NOTE: Refer to Hydrogen Gas Caution, page 4.
The water heater and pipes should also be drained if
they could be exposed to freezing temperatures. After
a long shutdown period, the water heater’s operation
and controls should be checked by a qualified service
technician. Confirm that the water heater is completely
filled before placing it in operation.
NOTE: Refer to Water Tank, page 10.

849-6000245 Rev. 0
Temperature Control
OPERATING INSTRUCTIONS
Water temperature can be adjusted by turning the knob
of the gas control/thermostat on the front of the water
heater. Always read and understand safety instructions
contained in the Use & Care Manual before adjusting the
temperature setpoint.
NOTE: Refer to Water Temperature in Safety
Information, page 5.
Safety and energy conservation should be considered
when selecting the temperature setpoint of the water
heater:
• The recommended setpoint for the water heater is 120°F
(49°C), as water temperatures above 125°F can cause
severe burns or death from scalding.
• Lower temperature setpoints increase energy savings.
• Higher temperature setpoints can increase the cleaning
performance of dishwashers and washing machines, as
well as killing bacteria.
Mixing Valves
If the water heater’s temperature is set above HOT
(120°F/49°C), supplemental mixing valves are
recommended to reduce point-of-use water temperature
by mixing hot and cold water in branch water lines.
Contact a licensed plumber or local plumbing authority for
additional information.
Vacation Setting
This setting is recommended when you will be away from
the home for an extended period of time and hot water
is not needed. The vacation setting will reduce the water
temperature to 50ºF (10°C) to conserve energy.
NOTE: Refer to Hydrogen Gas Caution, page 4.

49-6000245 Rev. 0 9
All temperatures listed on the water heater’s gas
control/thermostat are approximate.
Maximum water temperatures occur just after the water
heater has completed a heating cycle. To determine
the water temperature at point-of-use, open a hot water
faucet and hold a thermometer under the stream of
water.
Frequent, short uses of hot water can cause a
phenomenon called stacking, when the temperature
of the water at the top of the tank (closest to pipes
delivering water to the home) exceeds the temperature
at the bottom of the tank (where the gas control/
thermostat is located).
Before use, always test the water temperature with your
hand, keeping in mind that hotter water increases the
danger of scalding.
NOTE: Refer to Water Temperature in Safety
Information, page 5.
The gas control/thermostat is equipped with two safety
shut-off devices:
• One is designed to shut off gas to the water heater’s
burner if the pilot light goes out.
• The other is designed to shut off gas to the burner if
the water heater exceeds normal temperatures.
If one of these safety shut-off devices is activated, refer
to Troubleshooting Tips, page 20.
WARNING If the water heater overheats or the
gas supply fails to shut off, close the manual gas
shut-off valve.
Turn off gas to the water heater if it has been subjected
to overheating, fire, flood or physical damage. (Refer
to Lighting and Shutdown, page 7.) Do not operate the
water heater again until it has been thoroughly checked
by a qualified service technician.
Do not use or attempt to repair the water heater if any
part has been under water. Immediately call a qualified
service technician to replace the unit.

DANGER Risk of Scald - Before manually
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
may be due to thermal expansion in a closed water
system. Contact the water supplier or a qualified
service technician to correct this. Do not plug the
relief valve outlet.
At least once a year, lift and release the lever handle on
the temperature and pressure (T&P) relief valve, located
on the right side of the water heater. Flush several
gallons to the open drain below, confirming that the
water flows freely through the T&P valve and discharge
line.

1. Turn off the water heater and turn off gas to the unit.
(See To Turn Off Gas To Appliance, page 7.)
2. Attach a garden hose to the drain valve located at the
bottom of the unit and direct to a suitable 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.
Flushing the Tank:
1. Follow the 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 completely fill the tank
before turning on gas and relighting the unit. The tank

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.
The gas and cold water supply must 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 the warranty.
Inspecting the Anode Rod:
1. Turn off the water heater and drain 1-2 gallons of
water from the tank. (Refer to Draining the Tank, page
10.)
2. Remove the anode cap and foam insulation beneath
it with a flathead screwdriver. (Refer to illustration
below.)
3. Unscrew the anode rod using a 1 1/16” socket/wrench
and lift it out of the water heater.
4. Inspect the anode rod. If more than 6” of core wire is
exposed, the anode rod should be replaced. (Refer
to illustration below.) If the anode rod has not been
depleted, reinsert it into the water heater following
steps 2-6 below.
CAUTION DO NOT touch the vent hood or vent
pipe located in front of the anode rod. These are
very hot and present a burn hazard.
Installing the Anode Rod:
1. If a new anode rod is required, be sure to purchase the
same type. For further information, contact a qualified
service technician or GEA Customer Support at
GEAppliances.com/waterheater.
2. Apply pipe joint compound or pipe thread sealant tape to
the threads of the anode rod.
3. Insert the anode rod into the water heater and tighten
with a torque wrench to 50 +/- 5 ft-lbs. of torque.
4. Close the drain valve, turn on the water supply and open
a hot water faucet to remove any air trapped in the water
lines.
5. Check for any leaks and repair.
6. Ensure that the water heater is completely full before
relighting it. (Refer to Lighting Instructions, page 7.)

CARE AND CLEANING
Burner Inspection
Once a year, visually inspect the pilot light, then the
main burner while in operation. Through the sight glass,
confirm that both flames are blue and exhibit the pattern
shown in the illustration below. If a different flame pattern
or color is noted or soot has built up on the burner,
turn off the water heater and call a qualified service
technician.
CAUTION The pilot light and main burner are in
a sealed chamber. Only a qualified service technician
should access this chamber. Refer to Sealed Burner
Assembly Warning, page 4.
Once a year, visually inspect the water pipes and
connections, repairing any leaks or damaged fittings.
If you smell gas, refer to Lighting and Shutdown, page 7.
Check the water heater’s venting system:
1. Visually inspect the vent hood and vent pipes to
ensure they are firmly attached.

LOCATION (Cont.)
The installation must allow sufficient airflow for
combustion and ventilation, and should be as close to
a gas vent or chimney as possible. Avoid areas where
the water heater could be exposed to flammable
liquids and vapors or a corrosive atmosphere.
The water heater can be installed on combustible
flooring, but not directly on carpet. If the water heater
must be located in a carpeted area, install a wood or
metal panel as a barrier between the water heater
and carpet; the panel should be 5” larger than the
water heater in all directions.
To minimize thermal loss, the water heater should
be close to the areas of greatest demand. Insulated
water lines also help to maintain optimal temperatures
from water heater to faucet.
The installation must allow sufficient access to the
top, front and sides of the water heater for service.
Moving the water heater for service is not covered
under the warranty.
For installation requiring earthquake straps, minimal
clearance around the sides of the water heater is
acceptable. In this case, additional clearance should
be provided on the opposite side of the unit to allow
for service access. Refer to For Installations in the
State of California, page 4.
Refer to the rating plate beside the gas control/
thermostat on the front of the water heater for further
details.
Installation Instructions
INSTALLATION INSTRUCTIONS
LOCAL INSTALLATION
REGULATIONS
This appliance must be installed in accordance with
local codes or, in the absence of local codes, the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 or
the Natural Gas and Propane Installation Code, CSA
B149.1. Not for Installation in a Manufactured Home
(Mobile Home).
LOCATION
The water heater should be installed indoors, in a
dry, level area where the tank and water lines are
protected from freezing temperatures. If needed,
shims can be used under the base of the unit to
level it.
All water heaters are subject to leaking, due to the
corrosive properties of water over time. A ground
floor or basement installation is suggested, to avoid
property damage should leakage occur. Inspect and
maintain the water heater according to this manual
to minimize the potential for leakage and, if required,
install a catch pan piped to a suitable drain.
Catch Pan Installation (If Required)
NOTE: The auxiliary catch pan MUST conform
to local codes. Catch Pan Kits are available from
the store where the water heater was purchased
or GEApplianceparts.com. The catch pan outer

AIR SUPPLY AND VENTILATION
Proper air supply and ventilation are essential to
the safe, effective operation of this residential gas
water heater. Air supply and ventilation must be
in accordance with local codes or, in the absence
of local codes, the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 or the Natural Gas and Propane
Installation Code, CSA B149.1.
Air Supply
If the water heater is installed in an open room of
a conventionally constructed building, sufficient
air is typically present for proper combustion and
ventilation. However, if the water heater is installed
in a confined space or tightly insulated home,
additional provisions must be made for combustion
and ventilation air. A confined space offers less than
50 cubic feet of air per 1,000 BTUH (British thermal
units per hour) for the appliances in that space.
Each appliance’s BTUH requirements should be
listed on its rating plate.
Without an adequate supply of clean air, the water
heater’s pilot light will not function properly, and
excessive amounts of carbon monoxide may be
produced.
Corrosive Atmospheres
A corrosive atmosphere is created when compounds
from aerosol sprays, cleaning products such as
bleach and detergents or other chemicals become
airborne and are drawn into the combustion air
supply of a water heater or other gas appliance.
When these compounds pass through the gas
flame, they create corrosive elements that shorten
the life of the appliance. Damage due to a corrosive
atmosphere is not covered under the warranty.
Installation Instructions
INSTALLATION INSTRUCTIONS
THERMAL EXPANSION
If the home’s inlet water line includes a check valve,
this will prevent water from flowing back into the
city’s water supply, creating a closed water system in
the home. Heated water expands, causing increased
pressure, which is then trapped in a closed water
system. Referred to as thermal expansion, this rapid
pressure increase can cause the water heater’s
relief valve to operate (releasing water) during
heating cycles, potentially causing premature failure
of the valve or the water heater. To control thermal
expansion, install a thermal expansion tank in the
cold water line between the water heater and check
valve, as shown in the next illustration, page 16.
Contact your installing contractor, water supplier or
plumbing inspector for additional information.
AIR SUPPLY AND VENTILATION
(Cont.)
Ventilation
The ventilation system for this water heater must be
properly installed by a qualified service technician
and free from any obstructions. The vent should
not be shared by any power-vented appliance, nor
should a damper be used anywhere in the system.
The new vent hood (provided with the water heater)
must be attached to the gas vent or chimney by vent
pipes. The diameter of the vent pipes must match
that of the vent hood or be larger.
At least 12” of vertical vent pipe is recommended
from the vent hood. Horizontal pipes must maintain
a vertical pitch of at least 1/4” per foot, and the
termination must be vertical. Vent joints must be
secured by an approved method, such as sheet
metal screws.
After the water heater’s main burner has been in
operation for 5 minutes, the vent hood can be tested
for spillage by holding a lighted match or candle
close to the vent hood relief opening. The smoke or
flame should be pulled towards the opening.
For additional information, consult local codes, the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 or
the Natural Gas and Propane Installation Code, CSA
B149.1.

16 49-6000245 Rev. 0
WATER SUPPLY AND DRAINAGE
Refer to the illustration below for recommended installation. The HOT and COLD water connections are 3/4”
NPT (National Pipe Thread) and are clearly marked on all models. Use 3/4” female NPT fittings with sealant
suitable for potable water when connecting to the inlet/outlet ports. The installation of unions is recommended
on the HOT and COLD water
connections so that the water heater
may be easily disconnected for
service. Piping should be routed to
allow for anode rod inspection and
service.
NOTE: Install a shut-off valve in the
cold water line near the water heater.
This will allow for easier service and
maintenance of the unit.
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 the
water heater. Any heat applied
to the HOT or COLD water
connections 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.

TO FILL THE WATER HEATER
WARNING Risk of Unit Damage - The
tank must be full of water before the water heater
is turned on. The water heater warranty does not
cover damage or failure resulting from operation
with an empty or partially empty tank.
1. Check that the drain valve is completely closed.
2. Open the shut-off valve in the cold water supply
line.
3. Open hot water faucets slowly, allowing air to vent
from the water heater and pipes.
4. Wait until there is a steady flow of water from the
hot water faucets; this indicates that the water
heater is full.
5. Check connections and pipes for any leakage.
When the water heater is first filled with water,
condensation may form on the tank and fittings.
During use, condensation can be caused by a heavy
water draw and very cold inlet water temperature.
This condition is not unusual and will resolve after
the water is heated. If condensation persists,
examine fittings for potential leaks and repair as
required.
TEMPERATURE AND PRESSURE
RELIEF VALVE
WARNING Risk of Unit Damage - The
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 (T&P)
relief valve, complying with the Standard for Relief
Valves and Automatic Gas Shut-Off Devices for Hot
Water Supply Systems, ANSI Z21.22/CSA 4.4, 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 temperature and pressure
relief valve must not be less than the input rating
of the water heater as indicated on the rating plate
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
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.
(Model appearance may vary)
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 Shut-Off Devices for
Hot Water Supply Systems, ANSI Z21.22 /CSA
4.4. 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 circumstance.

heater and pose a hazard to persons or property.
If an insulation blanket is required by local codes:
• DO NOT cover or attempt to relocate warning
labels on the water heater.
• DO NOT insulate the top of the water heater; this
will interfere with proper functioning of the vent
hood.
• DO NOT cover the gas control/thermostat, gas
valve, burner access door or temperature and
pressure relief valve.
• DO NOT insulate the bottom of the water heater or
cover the combustion air inlets.
• FREQUENTLY INSPECT the insulation blanket
to ensure that it is securely in position and is not
restricting airflow to the combustion air inlets at the
base of the water heater.
Installation Instructions
INSTALLATION INSTRUCTIONS
GAS SUPPLY
WARNING Only connect this water heater
to the type of gas listed on its rating plate. Any
attempt to adapt the water heater for use with
a different type of gas could cause hazardous
operating conditions.
The gas supply line should be composed of an
approved gas piping material such as steel and
properly sized for the water heater. Install an ANSI
certified gas appliance connector or ground joint
union in the gas line close to the water heater.
Any flexible connectors in the gas line must be 36”
or shorter. Joint compound should be used sparingly
on male threads only and must be resistant to liquid
petroleum (LP) gas.
The National Fuel Gas Code (NFGC) requires that a
manual gas shut-off valve be installed.
A sediment trap must be installed downstream of the
shut-off valve, as close to the appliance as possible.
Refer to the illustration below.
Connect the pipe to the gas control/thermostat inlet
using a maximum torque of 40 ft-lbs. torque.
Gas pressure to the gas control/thermostat inlet
must not exceed 14” w.c. for natural gas or LP
gas. The rating plate lists both the maximum and
minimum inlet gas pressures for the water heater.
If gas pressure is not within the acceptable range,
contact your gas provider.
Pressure Testing
• Gas test pressures exceeding 14” w.c. (1/2 PSI or
3.5 kPa) require disconnecting the water heater
and gas shut-off valve from the gas supply line.
• Gas test pressures of 14” w.c. (1/2 PSI or 3.5 kPa)
or lower require isolating the water heater from the
gas supply line by closing the gas shut-off valve.

High Altitude
WARNING Do not install the water heater
above the altitude specified on its rating plate.
Installation above the certified altitude may cause
the water heater to produce excessive amounts
of carbon monoxide, which could cause serious
injury or death.
The water heater is certified for operation at high
altitudes. Please see the rating plate on the water
heater for maximum altitude.

COMBINATION POTABLE WATER AND SPACE HEATING
This water heater is suitable for combination potable water and space heating applications; it is not suitable for
space heating alone.
If installed for combination water and space heating, components in both systems must be suitable for potable
water. DO NOT connect the water heater to components that have been previously used for space heating
alone, as they may be contaminated with toxic chemicals. Never introduce boiler treatment or other toxic
chemicals into pipes or components connected with the water heater, as this will affect the potable water supply.
If the space heating system
requires water at a temperature
higher than 120°F (49°C),
a mixing valve (meeting the
Standard for Temperature
Actuated Mixing Valves for Hot
Water Distribution Systems, ASSE
1017) must be installed in the
potable hot water line to reduce
the danger of scalding.
Installation must comply with local
and national codes.
NOTE: A maximum distance of
50’ - 0” from the water heater
to fan coil (developed length) is
required in Massachusetts State.

Hot water has rotten egg or
sulfur smell
Certain water supplies with high
sulfate content will react with the
anode rod that is present in all water
heaters for corrosion protection of
the tank
• 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. See the Water Temperature Adjustment section, page 5, for
safety information. Installation of temperature limiting valves can be used to
reduce risk of scalding.
