FOREWORD
These designs comply with ANSI Z21.10.3/CSA 4.3 as an automatic
circulating or automatic storage tank type water heater.
Heaters having an input of 305,000 (89 kWh), 365,000 (107 kWh),
399,000 (117 kWh) and 500,000 (147 kWh) Btuh with a recovery
rating of 277.3 gph (1049 Lph) or more also comply with ANSI
Z21.10.3 as an automatic instantaneous type heater.
Detailed installation diagrams are found in this manual. These
diagrams will serve to provide the installer with a reference for the
materials and methods of piping necessary. It is highly essential
that all water, gas piping and wiring be installed as shown on the
diagrams.
Particular attention should be given to the install ation of
thermometers at the locations indicated on the diagrams as
these are necessary for checking the proper functioning of
the heater.
This model water heater is designed and manufactured in both
natural gas and propane versions. MAKE SURE the gas on which
the heater will operate is the same as that specied on the heater
model and rating plate.
These heaters may be installed on combustible oors. Refer
to LO C AT ING TH E HEATER a nd INS TA L L AT ION ON
COMBUSTIBLE FLOORING sections for details.
In addition to these instructions, the equipment shall be installed in
accordance with those installation regulations in force in the local
area where the installation is to be made. These shall be carefully
followed in all cases. Authorities having jurisdiction should be
consulted before installations are made.
The installation must conform to these instructions and the local
code authority having jurisdiction. In the absence of local codes,
the installation must comply with the latest editions of the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 and the National Electrical
Code, NFPA 70, CAN/CSA B149.1, and CSA 2 C22.1. The former
is available from the Canadian Standards Association, 8501 East
Pleasant Valley Road, Cleveland, OH 44131, and both documents
are available from the National Fire Protection Association, 1
Batterymarch Park, Quincy, MA 02269.
GENERAL SAFETY
INFORMATION
PRECAUTIONS
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN
UNDER WATER. Immediately call a qualied service technician
to inspect the appliance and to replace any part of the control
system and any gas control which has been under water.

IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT
OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE
BEEN MADE BY A QUALIFIED SERVICEMAN.
physical condition, such as having a cold or diminishing sense
of smell with age. For these reasons, the use of a propane gas
detector is recommended.
1. EXTERNAL FIRE.
2. DAMAGE.
3. FIRING WITHOUT WATER.
4. SOOTING
CHEMICAL VAPOR CORROSION
WARNING
CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY
OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN
CHEMICAL VAPORS. SUCH CORROSION MAY RESULT IN
FAILURE AND RISK OF ASPHYXIATION.
Spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, swimming pool chemicals, calcium
and sodium chloride (water softener salt), waxes, and process
chemicals and typical compounds which are potentially corrosive.
Do not store products of this sort near the heater. Also, air which
is brought in contact with a the heater should not contain any of
these chemicals. If necessary, uncontaminated air should be
obtained from remote or outside sources. The limited warranty
is voided when failure of water heater is due to a corrosive
atmosphere. (Refer to the limited warranty for complete terms
and conditions.)
IMPROPER COMBUSTION
WARNING
ATTIC AND/OR EXHA UST FANS OP ERATIN G ON THE
PREMISES WITH A WATER HEATER CAN RESULT IN CARBON
MONOXIDE POISONING AND DEATH.
OPERATION OF THESE FANS CAN PRODUCE A NEGATIVE
DRAFT IN THE AREA OF THE WATER HEATER PREVENTING
THE PRODUCTS OF COMBUSTION FROM EXHAUSTING
THROUGH THE CHIMNEY OR VENT PIPE.
The venting of the water heater should be inspected by a qualied
service technician at the time of installation and periodically
thereafter to ensure a down-draft condition does not exist.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION AND
VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.
LIQUID PETROLEUM MODELS
Water heaters for propane or liqueed petroleum gas (LPG) are
different from natural gas models. A natural gas heater will not
function safely on LP gas and no attempt should be made to
convert a heater from natural gas to LP gas.
LP gas must be used with great caution. It is highly explosive
and heavier than air. It collects rst in the low areas making its
odor difcult to detect at nose level. If LP gas is present or even
suspected, do not attempt to nd the cause yourself. Go to a
neighbor’s house, leaving your doors open to ventilate the house,
then call your gas supplier or service agent. Keep area clear until
a service call has been made.
At times you may not be able to smell an LP gas leak. One
cause is odor fade, which is a loss of the chemical odorant that
gives LP gas its distinctive smell. Another cause can be your
IF YOU EXPERIENCE AN OUT-OF-GAS SITUATION, DO NOT
TRY TO RELIGHT APPLIANCES YOURSELF, Ask your LP delivery
person to relight pilots for you. Only trained LP professionals
should conduct the required safety checks in accordance with
industry standards.
EXTENDED NON-USE PERIODS
WARNING
HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER
SYSTEM SERVED BY THIS HEATER THAT HAS NOT BEEN
USED FOR A LONG PERIOD OF TIME (GENERALLY TWO
WEEKS OR MORE). HYDROGEN GAS IS E XTREMELY
FLAMMABLE. To reduce the risk of injury under these conditions,
it is recommended that the hot water faucet be opened for several
minutes at the kitchen sink before using any electrical appliance
connected to the hot water system. If hydrogen is present, there
will probably be an unusual sound such as air escaping through
the pipe as the water begins to ow. THERE SHOULD BE NO
SMOKING OR OPEN FLAME NEAR THE FAUCET AT THE TIME
IT IS OPEN.
INSULATION BLANKETS
Insulation blankets available to the general public for external
use on gas water heaters are not approved for use on your
State water heater. The purpose of an insulation blanket is to
reduce the standby heat loss encountered with storage tank
water heaters. Your State water heater meets or exceeds the
ASHRAE/IES 90.1-1999 standards with respect to insulation
and standby loss requirement making an insulation blanket
unnecessary.
WARNING
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions. Failure to follow these
instructions can result in re, asphyxiation, serious personal
injury or death.
• Do not apply insulation to the top of the water heater, as this
will interfere with safe operation of drafthood.
• Do not cover the gas valve or temperature & pressure relief
valve.
• Do not cover the instruction manual. Keep it on the side of the
water heater or nearby for future reference.

HIGH ALTITUDE INSTALLATIONS
WARNING
INSTALLATION S ABO V E 2 000 FE E T (610 ME T E R S )
REQUIRE REPLACEMENT OF THE BURNER ORIFICES IN
ACCOR DANCE WITH T HE NATIONAL FUEL GAS CODE
(ANSI Z223.1). FAILURE TO REPLACE THE ORIFICES WILL
RESULT IN I MPROPER AND INEFFICIEN T OPERATI ON
OF THE APPLIANCE RESULTING IN THE PRODUCTION
5
OF INCREASED LEVELS OF CARBON MONOXIDE GAS
IN EXCESS OF SAFE LIMITS WHICH COULD RESULT IN
SERIOUS PERSONAL INJURY OR DEATH.
You should contact your gas supplier for any specic changes
which may be required in your area.
As elevat io n abo ve sea level is i nc re ased, t here is les s
oxygen per cubic foot of air. Therefore, the heater input
rate should be reduced at high altitudes for satisfact or y
operation with the reduced oxygen supply. Failure to make
this reduction would result in an overring of the heater
ca using sooti ng, poor comb ustion a nd/or uns atisfactory
heater performance.
Rati ngs speci ed by manufact urers fo r most applian ce s
apply for elevatio ns up to 2000 feet (610m). For elevations
above 2000 feet (610), ratings must be reduced at the rate of
4% for each 1000 feet (305m) above sea level. For example,
if a heater is rated at 120,000 Btuh (35 kWh) at sea level,
to ra te the heater at 400 0 feet (121 9m ), you subt ract 4
(once for each thou sand feet) x .04 (4% input reduction) x
120,000 (original rating) from the original rating. Therefore,
to calc ul at e t he input rating at 4,000 feet (121 .9 m): 4 x
.04 x 120,000 =19 ,200 Btuh (5.6 kWh), 120,000 ( 35 kWh)
- 19,200 (5.6 kWh) = 100,80 0 Btuh (29.4 kWh) . At 6000
feet (1829m) the correct input rating should be 91,200 Btuh
(26.7 kWh).
The input reduction is primarily achieved by reducing the size
of the main burner orices. To do this, the main burner orices
require replacement with orices sized for the particular installation
elevation. Correct orice sizing and parts may be obtained from
State Water Heaters. When ordering, be sure to state the model
number and the altitude of the location where the water heater
is being installed.
Upon completion of derating of the heater, adjustment to the
gas pressure regulator may be required. See CHECKING THE
INPUT section in this manual for inlet and manifold pressure
requirements.
Also due to the input rating reduction required at high altitudes,
the output rating of the appliance is reduced and should be
compensated for in the sizing of the equipment for application.
NOTE: The inlet tube may have 1, 3 or 7 cross-tubes.
FIGURE 2
For proper function, the hydro cannon must be oriented correctly.
There is a marked range on the pipe nipple that must be aligned
with the top of the inlet spud (check for label on the appliance) to
assure proper orientation. Please check to conrm that the marked
range is in alignment with the top of the spud. A pipe union is
supplied with the hydro cannon to help eliminate the possibility of
changing the orientation by accidentally over-tightening the inlet
supply line. Improper orientation of the hydro cannon may cause
temperature build-up issues or spells of colder than usual water
temperatures.
HIGH LIMIT SWITCH
The digital thermostat (Fig. 3) contains the high limit (energy cutoff)
sensor. The high limit switch interrupts main burner gas ow should
the water temperature reach 203°F (95°C).
In the event of high limit switch operation, the appliance cannot be
restarted unless the water temperature is reduced to approximately
120°F (49°C). The high limit reset button on the front of the control
then needs to be depressed.
Continued manual resetting of high limit control, preceded by
higher than usual water temperature is evidence of high limit
switch operation. The following is a possible reason for high limit
switch operation:
• A malfunction in the thermostatic controls would allow the gas
valve to remain open causing water temperature to exceed the
thermostat setting. The water temperature would continue to
rise until high limit switch operation.
Contact your dealer or service agent if continued high limit switch
operation occurs.
FEATURES
SELF-CLEANING HYDRO CANNON
Thes e uni ts include a self-cl ea ning hydro cannon in stalled
in t he fr ont w ate r inl et. See figure 2. The hydro cannon
must be oriented correctly for proper function. There is a
marked range on the pipe nipple portion of the hydro cannon,
that must be aligned with the top of the inlet spud. A label
above the jacket hole has an arrow that will point to the
marked portion of the pipe nipple if the orientation is correct.
If the arrow does not point within the marked range on the
pipe nipple, adjust the pipe nipple to correct. A pipe union is
supplied with the hydro cannon to reduce the probability of
misaligning the hydro cannon accidentally while tightening the
connection to the inlet water supply line. Improper orientation
of the hydro-canon can cause poor performance of the heater
and can significantly reduce outlet water temperatures during
heavy draws.

ELECTRONIC IGNITION CONTROL
Each heater is equipped with a Honeywell ignition module. The
solid state ignition control, g. 4, ignites the pilot burner gas by
creating a spark at the pilot assembly. Pilot gas is ignited and
burns during each running cycle. The main burner and pilot gases
are cut off during the OFF cycle. Pilot gas ignition is proven by the
pilot sensor. Main burner ignition will not occur if the pilot sensor
does not rst sense pilot ignition.

AUTOMATIC FLUE DAMPER DEVICE
All units are equipped with an automatic ue damper that reduces
heat loss during the OFF cycles. The automatic ue damper
drive assembly is a eld replaceable part and may be obtained
by contacting State Water Heaters.
Each automatic ue damper drive assembly is equipped with a
“Service Switch”, as shown in gure 5.
CIRCULATING PUMP
A ci r cul atin g pump is used wh en a sys tem re quir es a
ci rculati ng loop or there is a storage tank used in conjunction
with the heater. Refer to the piping diagrams in this manual
for electrical hookup information and install in accordance
with the current edition of the National Electrical Code ANSI/
NFPA No. 70.
Only all bronze circulators should be used with commercial
water heaters.
Although circulators are oiled and operated by the manufacturer
some circulators must be oiled again before operating. Please
refer to manufacturer’s instructions.
DISHWASHING MACHINE REQUIREMENT
These appliances meet the NSF Standard 5 for sanitary
installations when used with the following leg kits, Part No’s.
6570-0 and 6570-7.
All dishwashing machines meeting the National Sanitation
Foundation requirements are designed to operate with water
ow pressures between 15 and 25 psi (103 Kpa and 173
Kpa). Flow pressures above 25 psi (173 Kpa), or below
15 psi (103 Kpa), will result in improperly sanitized dishes.
Where pressures are high, a water pressure reducing or ow
regulating control valve should be used in 180°F (82°C) line to
the dishwashing machine, and should be adjusted to deliver
water between these limits.
The National Sanitation Foundation also recommends circulation
of 180°F (82°C) water. Where this is done, the circulation
should be very gentle so that it does not cause any unnecessary
turbulence inside the water heater. The circulation should be
just enough to provide 180°F (82°C) water at the point of take-off
to the dishwashing machine. Adjust ow by means of the plug
cock in the circulating line.
INSTALLATION INSTRUCTIONS
FIGURE 5
The “Service Switch” has 2 positions: AUTOMATIC OPERATION
and HOLD OPEN DAMPER. For normal operation the switch
should be in the AUTOMATIC OPERATION position.
If there is a problem with the damper the “Service Switch” can be
placed in the HOLD OPEN DAMPER position. When the switch
is placed in the HOLD OPEN DAMPER position the damper disc
will rotate to the open position and the heater may be used until
vent assembly is repaired or replaced. DO NOT turn the damper
disc manually; damage will occur to the drive assembly if operated
manually. Refer to TESTING DAMPER OPERATION section of
this manual for additional information.

WARNING
THERE IS A RISK IN USING FUEL BURNING APPLIANCES
SUCH AS GAS WATER HEATERS IN ROOMS, GARAGES OR
OTHER AREAS WHERE GASOLINE, OTHER FLAMMABLE
LIQUIDS OR ENGINE DRIVEN EQUIPMENT OR VEHICLES ARE
STORED, OPERATED OR REPAIRED. FLAMMABLE VAPORS
ARE HEAVY AND TRAVEL ALONG THE FLOOR AND MAY BE
IGNITED BY THE HEATER’S PILOT OR MAIN BURNER FLAMES
CAUSING FIRE OR EXPLOSION. SOME LOCAL CODES
PERMIT OPERATION OF GAS APPLIANCES IN SUCH AREAS
IF THEY ARE INSTALLED 18” (.50m) OR MORE ABOVE THE
FLOOR. THIS MAY REDUCE THE RISK IF LOCATION IN SUCH
AN AREA CANNOT BE AVOIDED.
DO NOT INSTALL THIS WATER HEATER DIRECTLY ON A
CARPETED FLOOR. A FIRE HAZARD MAY RESULT. Instead the
water heater must be placed on a metal or wood panel extending
beyond the full width and depth by at least 3 inches (7.6cm) in
any direction. If the heater is installed in a carpeted alcove, the
entire oor shall be covered by the panel. Also, see the DRAIN
REQUIREMENTS.
THE HEATER SHALL BE LOCATED OR PROTECTED SO IT
IS NOT SUBJECT TO PHYSICAL DAMAGE BY A MOVING
VEHICLE.
WARNING
FLAMMABLE ITEMS, PRESSURIZED CONTAINERS OR ANY
OTHER POTENTIAL FIRE HAZARDOUS ARTICLES MUST
NEVER BE PLACED ON OR ADJACENT TO THE HEATER.
OPEN CONTAINERS OR FLAMMABLE MATERIAL SHOULD
NOT BE STORED OR USED IN THE SAME ROOM WITH THE
HEATER.
THE HEATER MUST NOT BE LOCATED IN AN AREA WHERE
IT WILL BE SUBJECT TO FREEZING.
LOCATE IT NEAR A FLOOR DRAIN. THE HEATER SHOULD
BE LOCATED IN AN AREA WHERE LEAKAGE FROM THE
HEATER OR CONNECTIONS WILL NOT RESULT IN DAMAGE
TO THE ADJACENT AREA OR TO LOWER FLOORS OF THE
STRUCTURE.
WHEN SUCH LOCATIONS CANNOT BE AVOIDED, A SUITABLE
DRAIN PAN SHOULD BE INSTALLED UNDER THE HEATER.
Such pans should be fabricated with sides at least 2” (5cm) deep,
with length and width at least 2” (5cm) greater than the diameter
of the heater and must be piped to an adequate drain. The pan
must not restrict combustion air ow.

AIR REQUIREMENTS
REFER TO THE CURRENT EDITION OF THE “NATIONAL FUEL
GAS CODE” ANSI Z223.1/NFPA 54.
WARNING
KEEP APPLIANCE AREA CLEAR AND FREE OF COMBUSTIBLE
MATERIALS, GASOLINE AND OTHER FLAMMABLES, VAPORS
AND LIQUIDS.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION OR
VENTILATING AIR.
WARNING
FOR SAFE OPERATION PROVIDE ADEQUATE AIR FOR
COMBUSTION AND VENTILATION. AN INSUFFICIENT SUPPLY
OF AIR WILL CAUSE RECIRCULATION OF COMBUSTION
PRODUCTS RESULTING IN AIR CONTAMINATION THAT
MAY BE HAZARDOUS TO LIFE. SUCH A CONDITION OFTEN
WILL RESULT IN A YELLOW, LUMINOUS BURNER FLAME,
CAUSING CARBONING OR SOOTING OF THE COMBUSTION
CHAMBER, BURNERS AND FLUE TUBES AND CREATES A
RISK OF ASPHYXIATION.
Where an exhaust fan is supplied in the same room with
a heater, sufcient openings for air must be provided in
the walls. UNDERSIZED OPENINGS WILL CAUSE AIR TO
BE DRAWN INTO THE ROOM THROUGH THE CHIMNEY,
CAUSING POOR COMBUSTION. SOOTING MAY RESULT IN
SERIOUS DAMAGE TO THE HEATER AND RISK OF FIRE OR
EXPLOSION.
When drawing combustion and dilution air from inside a
conventionally constructed building to a conned space, such a
space shall be provided with two permanent openings, ONE IN OR
WITHIN 12 INCHES (30.5cm) OF THE ENCLOSURE TOP AND
ONE IN OR WITHIN 12 INCHES (30.5cm) OF THE ENCLOSURE
BOTTOM. Each opening shall have a free area of at least one
square inch per 1000 Btuh (2,225mm2/kW) of the total input of all
appliances in the enclosure, but not less than 100 square inches
(645 square cm).
If the conned space is within a building of tight construction,
air for combustion, ventilation, and draft hood dilution must be
obtained from outdoors. When directly communicating with the
outdoors or communicating with the outdoors through vertical
ducts, two permanent openings, located in the above manner,
shall be provided. Each opening shall have a free area of not
less than one square inch per 4000 Btuh (8,900mm2/kW) of the
total input of all appliances in the enclosure. If horizontal ducts
are used, each opening shall have a free area of not less than
one square inch per 2000 Btuh (4,450mm2/kW) of the total input
of all appliances in the enclosure.

VENTING
WATER LINE CONNECTIONS
WARNING
THE INSTRUCTIONS IN THIS SECTION ON VENTING MUST
BE FOLLOWED TO AVOID CHOKED COMBUSTION OR RECIRCULATION OF FLUE GASES. SUCH CONDITIONS CAUSE
SOOTING OR RISKS OF FIRE AND ASPHYXIATION.
Heater must be protected from freezing downdrafts.
Remove all soot or other obstructions from the chimney that will
retard a free draft.
Type B venting is recommended with these heaters. See table 3
TECHNICAL DATA VENTING.
This water heater must be vented in compliance with all local
codes, the current edition of the National Fuel Gas Code (ANSIZ223.1) and with the Category I Venting Tables.
If an y parts of t he vent sys tem are exp osed to ambient
temperatures below 35 degrees F (2 degrees C) they must be
insulated to prevent condensation.
• Do not connect the heater to a common vent or chimney with
solid fuel burning equipment. This practice is prohibited by
many local building codes as is the practice of venting gas
red equipment to the duct work of ventilation systems.
• Where a separate vent connection is not available and the
vent pipe from the heater must be connected to a common
vent with an oil burning furnace, the vent pipe should enter the
smaller common vent or chimney at a point above the large
vent pipe.
This manual provides detailed installation diagrams (see pages
16-22 of this manual) for typical methods of application for the
water heaters.
The water heater may be installed by itself, or with a separate
storage tank, on both single and two-temperature systems.
When used with a separate storage tank, the circulation may
be either by gravity or by means of a circulating pump. When a
circulating pump is used it is important to note that the ow rate
should be slow so that there will be a minimum of turbulence
inside the heater.
If a water heater is installed in a closed water system, contact
the water supplier or local plumbing inspector on how to control
this situation.
WATER (POTABLE) HEATING AND
SPACE HEATING
1. All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
2. Toxic chemicals, such as those used for boiler treatment, shall
NEVER be introduced into this system.
3. This unit may NEVER be connected to any existing heating
system or component(s) previously used with a non-potable
water heating appliance.
4. When the system requires w at er for spa ce heating at
temperatures higher than required for domestic water purposes,
a tempering valve must be installed. Please refer to installation
diagrams on pages 16 through 22 in this manual for suggested
piping arrangements.
CAUTION
A closed system will exist if a check valve (without bypass),
pressure reducing valve (without bypass), or a water meter (without
bypass) is installed in the cold water line between the water heater
and street main (or well).
FIGURE 8
MULTIPLE HEATER MANIFOLD
Figure 9 and table 3 should be used for horizontally manifolding two
or more heaters. Also see MULTIPLE-UNIT INSTALLATIONS of
MECHANICAL VENTING section for induced draft applications.
FIGURE 9
Excessive pressure may develop in such closed systems, causing
premature tank failure or intermittent relief valve operation. This
is not a warranty failure. An expansion tank or a similar device
may be required in the inlet supply line between the appliance
and the meter or valve to compensate for the thermal expansion
of the water.
SYSTEM CONNECTIONS
The system installation must conform to these instructions and to
the local code authority having jurisdiction. Good practice requires
that all heavy piping be supported.
THERMOMETERS (Not Supplied)
Thermometers should be obtained and eld installed as shown in
the installation diagrams.
Thermometers are installed in the system as a means of detecting
the temperature of the outlet water supply.
RELIEF VALVE
This water heater is equipped with a combination temperaturepressure relief valve that complies with the standard for relief
valves and automatic gas shutoff devices for hot water supply
system, ANSI Z21.22. FOR SAFE OPERATION OF THE WATER
