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.
FOREWORD
These designs comply with ANSI Z21.10.3/CSA 4.3 M98 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.
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
Detailed installation diagrams are found in this manual. These National Fuel Gas Code, ANSI Z223.1/NFPA 54 and the National
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.
Electrical Code, NFPA70, CAN/CSAB149.1-00, and CSA2 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.
Particular attention should be given to the installation of
thermometers at the locations indicated on the diagrams as
these are necessary for checking the proper functioning of the
heater.
GENERAL SAFETY
INFORMATION
PRECAUTIONS
The heater is designed to operate on natural or propane gases.
HOWEVER, MAKE SURE the gas on which the heater will operate
is the same as that specified on the heater model and rating
plate.
DO NOTUSETHISAPPLIANCE IFANYPARTHAS BEEN UNDER
WATER. Immediately call a qualified service technician to
inspect the appliance and to replace any part of the control
system and any gas control which has been under water.
These heaters may be installed on combustible floors. Refer
to LOCATING THE HEATER and INSTALLATION ON
COMBUSTIBLE FLOORING sections for details.

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.
IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT
OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE
BEEN MADE BY A QUALIFIED SERVICEMAN.
IF YOU EXPERIENCE AN OUT-OF-GAS SITUATION, DO NOT
TRY TO RELIGHTAPPLIANCES YOURSELF,Ask your LPdelivery
person to relight pilots for you. Only trained LP professionals
should conduct the required safety checks in accordance with
industry standards.

CHEMICAL VAPOR CORROSION
EXTENDED NON-USE PERIODS
WARNING
WARNING
CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY
OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN
CHEMICAL VAPORS. SUCH CORROSION MAY RESULT IN
FAILUREAND RISK OFASPHYXIATION.
HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER
SYSTEM SERVED BYTHIS HEATERTHATHAS NOT BEENUSED
FORALONG PERIOD OF TIME (GENERALLY TWO WEEKS OR
MORE). HYDROGEN GAS IS EXTREMELY 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 flow. THERE SHOULD BE NO
SMOKING OR OPEN FLAME NEAR THE FAUCETATTHE TIME
IT IS OPEN.
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.)
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 90.1b-1999 standards with respect to insulation
and standby loss requirement making an insulation blanket
unnecessary.
IMPROPER COMBUSTION
WARNING
ATTIC AND/OR EXHAUST FANS OPERATING ON THE
PREMISES WITHAWATER HEATER CAN RESULT IN CARBON
MONOXIDE POISONINGAND DEATH.
WARNING
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.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions. Failure to follow these
instructions can result in fire, 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.
Do not allow insulation to come within 2” (5cm) of the burners,
to prevent blockage of combustion air flow to the burners.
Do not allow insulation to come within 9” (23cm) of floor,
(within 2” (5cm) of bottom cover) to prevent blockage of
combustion air flow to the burners.
Do inspect the insulation blanket frequently to make sure it
does not sag, thereby obstructing combustion air flow.
Do obtain new labels from State for placement on the blanket
directly over the existing labels.
The venting of the water heater should be inspected by a qualified
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 liquefied 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 first in the low areas making its
odor difficult to detect at nose level. If LP gas is present or even
suspected, do not attempt to find 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.
HIGH ALTITUDE INSTALLATIONS

DEATH.
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.
You should contact your gas supplier for any specific changes
which may be required in your area.
As elevation above sea level is increased, there is less oxygen
per cubic foot of air. Therefore, the heater input rate should be
reduced at high altitudes for satisfactory operation with the
reduced oxygen supply. Failure to make this reduction would
result in an overfiring of the heater causing sooting, poor
combustion and/or unsatisfactory heater performance.
U.S. REQUIREMENTS
NOTE: The inlet tube may have 1, 3 or 7 cross-tubes.
FIGURE2
Ratings specified by manufacturers for most appliances apply
for elevations 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 rate the heater
at 4000 feet (1219m), you subtract 4 (once for each thousand
feet) x .04 (4% input reduction) x 120,000 (original rating) from
the original rating. Therefore, to calculate the input rating at
4,000 feet (121.9m): 4 x .04 x 120,000 =19,200 Btuh (5.6 kWh),
120,000 (35 kWh) - 19,200 (5.6 kWh) = 100,800 Btuh (29.4 kWh).
At 6000 feet (1829m) the correct input rating should be 91,200
Btuh (26.7 kWh).
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 confirm 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 (E.C.O.)
CANADIAN REQUIREMENTS
Appliances with inputs up to and including 400,000 BTU (117.2
kW) must be factory equipped with orifices for operation at
specific elevations. Standard (sea level) orifices permit
operation up to 2000' (610m) elevation. For operation between
2000' (610m) and 4500' (1370m) specify "HIGH ALTITUDE
OPERATION" when ordering the heater(s). For operation above
4500' (2370m) consult factory before ordering.
The dual bulb controller (fig. 3) contains the high limit (energy
cutoff) sensor. The high limit switch interrupts main burner gas
flow should the water temperature reach 205°F (96°C).
In the event of high limit switch operation, the appliance cannot
be restarted unless the water temperature is reduced by at least
20°F (11°C) and the high limit reset button on front of limit control
(fig. 3) is depressed.
Field conversion for operation at altitudes other than
that specified on the heater rating plate is not
permitted.
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.
The input reduction is primarily achieved by reducing the size of
the main burner orifices. To do this, the main burner orifices
require replacement with orifices sized for the particular
installation elevation. Correct orifice 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.
•
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 servicer if continued high limit switch
operation occurs.
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.
FEATURES
SELF-CLEANING HYDRO CANNON
These units include a self-cleaning hydro cannon installed in
the front water inlet. See figure 2. The hydro cannon must be
oriented correctly for proper function. There is a marked range

Continued pilot outage preceded by higher than usual water
temperature is evidence of high limit switch operation. Contact
your dealer or servicer to determine the reason for operation.
CIRCULATING PUMP
A circulating pump is used when a system requires a circulating
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 latest
version of the National Electric Code ANSI/NFPA No. 70. For
Canada refer to Canadian Code CSA C22.1.
ELECTRONIC IGNITION CONTROL
Each heater is equipped with a Honeywell ignition module. The
solid state ignition control, fig. 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 first sense pilot ignition.
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 National Sanitation Foundation
Standard 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
flow 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 flow 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.
HONEYWELL IGNITION MODULE
S8600M Continuous Re-Try
FIGURE4
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 flow by means of
the plug cock in the circulating line.
AUTOMATIC FLUE DAMPER DEVICE
All units are equipped with an automatic flue damper that reduces
heat loss during the OFF cycles. The automatic flue damper
drive assembly is a field replaceable part and may be obtained
by contacting State Water Heaters.
Each automatic flue damper drive assembly is equipped with a
“Service Switch”, as shown in figure 5.

should be in the AUTOMATIC OPERATION position.
The heater is shipped with the flue damper already installed.
The wiring conduit runs from the thermostat to the damper drive
cover. Before turning unit on, check to make sure the wiring
conduit is securely plugged into damper drive.
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.
LOCATING THE HEATER
When installing the heater, consideration must be given to proper
location. Location selected should be as close to the stack or
chimney as practicable, with adequate air supply and as
centralized with the piping system as possible.

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 flow rate
should be slow so that there will be a minimum of turbulence
inside the heater.
Remove all soot or other obstructions from the chimney that will
retard a free draft.
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.
Type B venting is recommended with these heaters. See table 3
TECHNICALDATAVENTING.
This water heater must be vented in compliance with all local
codes, the current revision of the National Fuel Gas Code (ANSI-
Z223.1) and with the Category I Venting Tables.
WATER (POTABLE) HEATING AND
SPACE HEATING
In Canada, venting shall conform to the requirements of the
current CAN/CGA B149.1-00 installation code.
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 water for space 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.
If any parts of the vent system are exposed 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
fired 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.
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).

ASME ratings cover pressure relief capacities. A.G.A. ratings
cover release rate with temperature actuation.
WARNING
THE HEATER IS NOT INTENDED FOR OPERATIONAT HIGHER
In addition to the appliance relief valve, each remote storage
tank which may be used in conjunction with this appliance shall
also be installed with a properly sized, rated and approved
combination temperature (ANSI) and pressure (ASME) relief
valve(s).
THAN 14.0" W.C.(3.48 Kpa) (1/2 POUND PER SQUARE INCH
GAGE- 3.45 Kpa) SUPPLY GAS PRESSURE. EXPOSURE TO
HIGHER SUPPLY PRESSURE MAY CAUSE DAMAGE TO THE
GAS VALVE WHICH COULD RESULT IN FIRE OR EXPLOSION.
IF OVERPRESSURE HAS OCCURRED SUCH AS THROUGH
IMPROPER TESTING OF GAS LINES OR EMERGENCY
MALFUNCTION OF THE SUPPLY SYSTEM, THE GAS VALVE
MUST BE CHECKED FOR SAFE OPERATION. MAKE SURE
THAT THE OUTSIDE VENTS ON THE SUPPLY REGULATORS
AND THE SAFETY VENT VALVESARE PROTECTEDAGAINST
BLOCKAGE. THESE ARE PARTS OF THE GAS SUPPLY
SYSTEM, NOT THE HEATER. VENT BLOCKAGE MAY OCCUR
DURING ICE STORMS.
WARNING
THE PURPOSE OF RELIEF VALVE IS TO AVOID EXCESSIVE
PRESSURE OR TEMPERATURE INTO THE STEAM RANGE,
WHICH MAY CAUSE SCALDING AT FIXTURES, TANK
EXPLOSION, SYSTEM OR HEATER DAMAGE. NO VALVE IS TO
BE PLACED BETWEEN THE RELIEF VALVE AND TANK.
Your local code authority may have other specific relief valve
requirements.
IT IS IMPORTANT TO GUARD AGAINST GAS VALVE FOULING
FROM CONTAMINANTS IN THE GAS WAYS. SUCH FOULING
MAY CAUSE IMPROPER OPERATION, FIRE OR EXPLOSION.
A DRAIN LINE MUST BE CONNECTED TO THE RELIEF VALVE
TO DIRECT DISCHARGE TO A SAFE LOCATION TO AVOID
SCALDING OR WATER DAMAGE. THIS LINE MUST NOT BE
REDUCED FROM THE SIZE OF THE VALVE OUTLETAND MUST
NOT CONTAIN VALVES OR RESTRICTIONS NOR SHOULD IT
BE LOCATED IN FREEZINGAREAS. DO NOTTHREAD OR CAP
THE END OF THIS LINE. RESTRICTED OR BLOCKED
DISCHARGE WILLDEFEATTHE PURPOSE OF THE VALVEAND
IS UNSAFE. DISCHARGE LINE SHALL BE INSTALLED TO
ALLOW COMPLETE DRAINAGE OF BOTH THE VALVEAND LINE.
IF COPPER SUPPLY LINES ARE USED THEY MUST BE
INTERNALLY TINNED AND CERTIFIED FOR GAS SERVICE.
BEFOREATTACHING THE GAS LINE, BE SURE THATALLGAS
PIPE IS CLEAN ON THE INSIDE.
TO TRAP ANY DIRT OR FOREIGN MATERIAL IN THE GAS
SUPPLY LINE, A DIRT LEG (SOMETIMES CALLED SEDIMENT
TRAP OR DRIP LEG) MUST BE INCORPORATED IN THE PIPING
(SEE FIG. 10). THE DIRT LEG MUST BE READILYACCESSIBLE
AND NOT SUBJECTTO FREEZING CONDITIONS. INSTALL IN
ACCORDANCE WITH RECOMMENDATIONS OF SERVING GAS
SUPPLIERS. REFER TO THE LATEST VERSION OF THE
NATIONALFUEL GAS CODE. For Canadian installations consult
Canadian Installation Code CAN/CSA B149.1-00.
See SERVICE INFORMATION section for procedure and
precautions.
GAS PIPING
Contact your local gas service company to ensure that adequate
gas service is available and to review applicable installation
codes for your area.
To prevent damage, care must be taken not to apply too much
torque when attaching gas supply pipe to gas valve inlet.
Size the main gas line in accordance with Table 4. The figures
shown are for straight lengths of pipe at 0.5 in. W.C. pressure
drop, which is considered normal for low pressure systems.
Note: Fittings such as elbows, tees and line regulators will
add to the pipe pressure drop. Also refer to the latest version
of the National Fuel Gas Code. For Canadian installations consult
Canadian Installation Code CAN/CSA B149.1-00.
Apply joint compounds (pipe dope) sparingly and only to the
male threads of pipe joints. Do not apply compounds to the first
two threads. Use compounds resistant to the action of liquefied
petroleum gases.

that attach to faucets to limit hot water temperatures. Contact a
licensed plumber or the local plumbing authority.
ADJUSTMENTS
ON INITIALSTARTUPSOMEADJUSTMENTSARE NECESSARY.
1. CHECK MANIFOLDAND INLET GAS PRESSURES.
The water temperature is controlled by a thermostat, Fig. 3, which
has two sensing elements. One sensor is located near the top
of the tank and the other is near the center. The thermostat is set
in the lowest position before the heater leaves the factory.
2. TO ADJUST PILOT FLAME - FOLLOW “PILOT BURNER”
PROCEDURE UNDER “PREVENTIVE MAINTENANCE”.
WATER TEMPERATURE CONTROL
The thermostat temperature dial, Fig. 3, is accessible by
removing the control cover. The dial is adjustable and may be
set for 120°F (49°C) to 180°F (82°C) water temperature, but
120°F (49°C) is the recommended starting point. It is suggested
the dial be placed on the lowest setting which produces an
acceptable hot water supply. This will always give the most
energy efficient operation. The temperature control has a 4°F
fixed differential.
TESTING DAMPER OPERATION
With the Service Switch in theAUTOMATIC OPERATION position,
check the operation of the flue damper three (3) times with the
water operating controls for proper operating sequence:
WARNING
THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE
THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT
WATER TEMPERATURES REQUIRED FOR AUTOMATIC
DISHWASHER AND LAUNDRY USE CAN CAUSE SCALD
BURNS RESULTING IN SERIOUS PERSONAL INJURY AND/
OR DEATH. THE TEMPERATUREAT WHICH INJURY OCCURS
VARIES WITH THE PERSON’SAGEAND TIME OF EXPOSURE.
THE SLOWER RESPONSE TIME OF CHILDREN, AGED OR
HANDICAPPED PERSONS INCREASES THE HAZARDS TO
THEM. NEVER ALLOW SMALL CHILDREN TO USE A HOT

The damper disc must be open (in the vertical position) before
the ignition and combustion process begins.
The damper disc must be in the open position when the
main burner is firing.
The gas valve must close and the main burner must have
ceased firing before the damper disc begins its return to the
closed (horizontal) position.
If during testing of the operation of the damper you find that there
is a problem with the operation of the water heater when the
Service Switch is in the AUTOMATIC OPERATION position:
Reset the Service Switch to the HOLD OPEN DAMPER position
and check operation again.
THE WATER HEATER SHOULD BE LOCATED IN AN AREA
WHERE THE GENERALPUBLIC DOES NOT HAVEACCESS TO
SET TEMPERATURES.
If the water heater does operate when placed in the HOLD OPEN
DAMPER position:
SETTING THE WATER HEATER TEMPERATUREAT 120°F WILL
REDUCE THE RISK OF SCALDS. Some states or provinces
require settings at specific lower temperatures.
•
Refer to the EFFIKAL RVGP-FSF-SERIES TROUBLE-
SHOOTING GUIDE at the end of this manual.
Below you will find listed the approximate time-of-burn
relationship for normal adult skin. Short repeated heating cycles
caused by small hot water uses can cause temperatures at the
point of use to exceed the thermostat setting by up to 20°F (11°C).
CAUTION
Do not force the damper disc manually or motor damage will
occur.
If you experience this type of use, you should consider using

•
If the back draft cannot be corrected by the normal method or
if a suitable draft cannot be obtained, a blower type flue gas
exhauster must be employed to assure proper venting and
correct combustion.
PILOT BURNER ASSEMBLY
PREVENTIVE MAINTENANCE
CHECK THE PILOT
At least once a year, check the pilot burner, fig. 15, and the main
burner, fig. 16, for proper operation. Refer to the following pilot
and main burner sections.
PILOT BURNER
For access to pilot, unfasten two screws to burner cover and
remove. Locate the burner with pilot and remove screw holding
burner to manifold. Unfasten pilot tubing from valve and slide
out burner and pilot.
FIGURE15
MAIN BURNER
Servicing of the pilot burner includes keeping pilot free of lint,
cleaning the burner head, the primary air opening and the orifice
of the pilot burner.
The main burner, fig. 15, should display the following
characteristics:
•
•
•
Cause rapid ignition and carry over of flame across entire
burner.
Pilot burner flame is affected by:
1. Low gas pressure.
Give reasonably quiet operation during ignition, burning and
extinction.
• Adjust pilot flame by means of the pilot gas adjustment
located on the gas valve. See fig. 17.
Cause no excessive lifting of flame from burner ports.

TYPICAL PILOT AND MAIN BURNER FLAMES
If the gas valve becomes defective, repairs should not be
attempted. A new valve should be installed in place of the
defective one.
CHECKING THE INPUT
For appliance installation locations with elevations above 2000
feet (610 m), refer to HIGH ALTITUDE INSTALLATIONS section
of this manual for input reduction procedure.
FIGURE16
1. Attach a pressure gauge or a manometer to the gauge port
and refer to Table 5, for correct manifold pressure.
If the preceding burner characteristics are not evident, check for
accumulation of lint or other foreign material that restricts or
blocks the air openings to the burner or heater.
2. Use this formula to “clock” the meter. Be sure that other gas
consuming appliances are not operating during this interval.
NOTE: Cleaning of main burners.
1. Remove main burners from unit.
3600 X H = Btuh
T
2. Check that burner venturi and ports are free of foreign matter.
T = Time in seconds to burn one cubic foot of gas.
H = Btu’s per cubic foot of gas.
3. Clean burners with bristle brush and/or vacuum cleaner —
DO NOT distort burner ports or pilot location.
4. Reinstall burners in unit. Make sure front and rear of burners
are installed correctly in burner support brackets.
Btuh = Actual heater input.
Also check for good flow of combustion and ventilating air to the
unit. Maintain a clear area around the heater at all times.
Example: (Using SBD-240 heater)
T = 15.8 seconds
H = 1050 Btu
Btuh = ?
GAS VALVES
Figure 16 shows the two types of combination gas control valves
used on these heaters.
36.8 X 1050 = 240,000 Btuh (70.3 kWh) (Compare with
15.9 heater model and rating)
Should it be necessary to adjust the gas pressure to the burners
to obtain the full input rate, the steps below should be followed:
3. Remove the regulator adjustment sealing cap, fig. 17, and
adjust the pressure by turning the adjusting screw with a
screwdriver.
Clockwise to increase gas pressure and input rate.
Counterclockwise to decrease gas pressure and input
rate.
4. “Clock” the meter as in step 2 above.
5. Repeat steps 3 and 4 until the specified input rate is achieved.
6. Turn the gas control knob to PILOT. Remove the pressure
gauge and replace the sealing cap and the allen wrench set
screw in the pressure tap opening.
WARNING
UNDER NO CIRCUMSTANCES SHOULD THE GAS INPUT
EXCEED THE INPUT SHOWN ON THE HEATER MODEL AND
RATING PLATE. OVERFIRING COULD RESULT IN DAMAGE OR
SOOTING OF THE HEATER.
When the heater is operating at full capacity, or full gas input, it
should consume 1 cu. ft. of gas in time indicated on Table 6.

the factory installed magnesium anodes with aluminum anodes
may correct the condition.
VENTING SYSTEM
Examine the venting system every six months for obstructions
and/or deterioration of the vent piping.
Occasionally water softener companies recommend removal of
heater anodes for odor reasons.
Remove all soot or other obstructions from chimney which will
retard free draft.
CAUTION
Unauthorized removal of the anode(s) will void the warranty. For
further information contact your dealer.
REMOTE STORAGE TANK
TEMPERATURE CONTROL
ANODE ROD INSPECTION
The water temperature in the storage tank (if used) is controlled
by the storage tank temperature control. The sensing element
is mounted in the hot water storage tank, see page 17.
The heater tank is equipped with anode rods to provide corrosion
control. At least once a year the anode rods should be checked
to determine if replacement is necessary. Initially the anode
rods are approximately 7/8" (22mm) in diameter with a 1/8" (3mm)
diameter steel core wire running down the center of the anode
material. THE ANODES SHOULD BE REPLACED when the 1/8"
(3mm) diameter core wire is visible as this means that the anode
material has been expended in the control of corrosion.
A change in water temperature in the storage tank lower than the
tank temperature control setting will cause the sensor to activate
the circulating pump. The pump then circulates the water through
the heater where the thermostat senses the drop in water
temperature and activates main burner operation of the appliance.
If the storage tank temperature control is out of calibration, replace
with new control.
For models with top inlet and outlet, it is recommended that,
before removing the inner cover for cleaning, inspection or
removal of inner parts, you obtain two new nipple collars, part
no. 74060. The nipple collars on the heater will usually be
damaged when removed. New pipe collars will insure that the
seal is such as to prevent leakage of flue products when properly
installed.
WARNING
SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL
TO SHUTOFF, TURN OFF THE MANUAL GAS CONTROLVALVE
TO THE APPLIANCE.
RELIEF VALVE
NOTE: Anode rod inspection may need to be made more
frequently in areas subject to acid rain that obtains their water
supply from surface water as the low pH will accelerate anode
activity.
At least once a year, the temperature and pressure relief valve
should be checked to ensure that it is in operating condition. Lift
the lever at the top of the valve several times until the valve seats
properly and operates freely.
CAUTION: Close cold water inlet valve serving heater and
open nearby hot water faucet to relieve the pressure in the
heater before attempting to remove anode(s) for inspection.
If the appliance installation includes other relief valves, such as
in “remote” storage tanks etc., check their relief valve operation
with the same frequency.
WARNING
RECOMMENDED PROCEDURE FOR
PERIODIC REMOVAL OF LIME DEPOSITS
FROM TANK TYPE COMMERCIAL WATER
HEATERS
THE WATER PASSING OUT OF THE VALVE DURING THIS
CHECKING OPERATION MAY BE EXTREMELY HOT. AVOID
CONTACT AND DISCHARGE SAFELY TO PREVENT WATER
DAMAGE.
If the temperature and pressure relief valve on the heater
discharges periodically or continuously, a problem exists. This
may be due to unusually high water temperatures or pressures
in the system, or to a faulty relief valve. Contact your dealer or a
qualified service technician to find the cause of the problem and
to correct it. This may also be due to thermal expansion in a
closed water supply system. Contact the water supplier or local
plumbing inspector on how to correct this situation. DO NOT
PLUG THE TEMPERATUREAND PRESSURE RELIEF VALVE.
The amount of calcium carbonate (lime) released from water is
in direct proportion to water temperature and usage, see chart.
The higher the water temperature or water usage, the more lime
deposits are dropped out of the water. This is the lime scale
which forms in pipes, heaters and on cooking utensils.
Lime accumulation not only reduces the life of the equipment
but also reduces efficiency of the heater and increases fuel
consumption.
WARNING
The usage of water softening equipment greatly reduces the
hardness of the water. However, this equipment does not always
remove all of the hardness (lime). For this reason it is
recommended that a regular schedule for deliming be
maintained.

HOT WATER ODOR
The time between cleaning will vary from weeks to months
depending upon water conditions and usage.
On occasion, hot water may develop a strong odor. If this occurs

DELIMING SOLVENTS
State recommends the use of UN•LIME for deliming. UN•LIME
is a patented food grade acid which is safe to handle and does
not create the harmful fumes which are associated with other
products.
UN•LIME may be obtained from your dealer, distributor or State
Water Heaters. Order part no. 4763 (1 gal), packed 4 gallons
per case or part no. 4813 (5 gallon container).
FIGURE 18
In some water areas the sediment might not be removed by this
method and may result in the water heater making rumbling or
boiling noises. To dissolve and remove these more stubborn
mineral deposits, State UN•LIME Professional Delimer should
be used.
Hydrochloric base acids are not recommended for use on glass-
lined tanks.
CAUTION
DELIMING USING FLO-JUG METHOD
Observe handling instructions on label of product being used.
UN•LIME in the 5 gallon size is recommended for deliming of
the SBD 120-500 models. UN•LIME with the necessary hoses
and fittings to delime your heater is also available as a kit:
Up-N-Down Transfer Kit. Contact your local State dealer or
distributor:
TANK CLEANOUT PROCEDURE
The following practices will ensure longer life and enable the
unit to operate at its designed efficiency:
1. Once a month the heater should be flushed. Open the drain
valve and allow two gallons of water to drain from the heater.
Inlet water valve should remain open to maintain pressure in
tank.
Telephone: (800) 433-2545
Fax: (800) 433-2515
Prepare the Water Heater
2. A cleanout opening is provided for periodic cleaning of the
tank. Gas must be shut off and heater drained before opening
cleanout.
To delime the water heater using the Flo-Jug method, first
prepare the heater for deliming as described in the "Why? When?
and How?" booklet, Form No. 4800. Then install the long plastic
male adapter fitting into the drain valve opening of the water
heater. Use teflon tape and hand tighten only. Do not overtighten.
To clean heater through cleanout opening, proceed as follows:
1. Drain heater.
Prepare the Up-N-Down Transfer Kit
The next step is the preparation on the Up-N-Down Transfer Kit,
if you have not already done so:
2. Remove outer cover plate from lower side of heater jacket.

1. With the 5 gallon Up-N-Down container in the vertical position,
unscrew the plastic vent cap in the handle and pierce the
plastic membrane over the vent boss under the cap to allow
the container to vent.

Check that “main manual gas shutoff valve” is fully open
and that gas service has not been interrupted.
Check that after following the appliance OPERATING
INSTRUCTIONS, the “Top Knob” of the appliance gas valve
is in “ON” position.
Note: If your container does not have the vent cap and vent
boss, drill a 3/16" hole in the handle. When you have finished
deliming you will be able to plug this drilled vent with the
stainless steel screw that is supplied with the kit.

Check electrical supply to the appliance for possible blown
(or tripped) fusing or power interruption.
2. Remove the container's cap and cut the plastic membrane
located in the 3/4" IPT opening in the cap. Take care to not
damage the threads.
Is the water temperature in tank below the thermostat dial
setting on the appliance thermostat (calling for heat)?
3. Find the 3/4" male adapter, apply teflon tape to the threaded
end and screw it into the 3/4" IPT opening in the cap.
It is possible that the high limit (E.C.O.) has functioned to
shut off the appliance. See FEATURES — Water Temperature
Control for reset procedure. Contact your serviceman if
limit continues to function to shut off appliance.
4. Put cap with male adapter back on the container and slide
3/4" hose over end of male adapter and fasten in place using
hose clamp provided.

SERVICE
5. Slide the hose clamp over end of hose and slide hose over
the male adapter in the water heater drain opening and
secure in place using hose clamp.
The installer may be able to observe and correct certain problems
which may arise when the unit is put into operation. HOWEVER,
it is recommended that only qualified servicemen, using
appropriate test equipment, be allowed to service the heater.
6. Lift container to the "Pour" Position, see Figure 9, being careful
to keep the vent in the handle above the liquid level and pour
the UN•LIME into the heater.
7. Lower container, you may have to place the container on its
empty carton to prevent the UN•LIME from flowing back into
the container.
As preliminary step, check wiring against diagram, check for
grounded, broken or loose wires. Check all wire ends to be
sure that they are making good contact.
8. Let UN•LIME remain in the heater for 5 minutes and then
lower the container to the "Drain" Position, see Figure 9.
ELECTRICAL SERVICING
9. Deliming activity is indicated by foaming on the surface of the
UN•LIME. If there is deliming activity, repeat steps 6 thru 8.
