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 FAUCET AT THE 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 90.1-1999 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 WITH A WATER HEATER CAN RESULT IN CARBON
MONOXIDE POISONING AND 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.
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 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.
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
WARNING
INSTALLATIONS ABOVE 2000 FEET (610 METERS)
REQUIRE REPLACEMENT OF THE BURNER ORIFICES IN
ACCORDANCE WITH THE NATIONAL FUEL GAS CODE
(ANSI Z223.1). FAILURE TO REPLACE THE ORIFICES WILL
RESULT IN IMPROPER AND INEFFICIENT OPERATION
OF THE APPLIANCE RESULTING IN THE PRODUCTION
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
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 specific changes
which may be required in your area.
NOTE: The inlet tube may have 1, 3 or 7 cross-tubes.
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.
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 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.
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).
HIGH LIMIT SWITCH
The digital thermostat (Fig. 3) contains the high limit (energy cutoff)
sensor. The high limit switch interrupts main burner gas flow 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.
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.
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:
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.
• 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.
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.
Contact your dealer or service agent if continued high limit switch
operation occurs.
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 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.
DIGITAL THERMOSTAT
FIGURE 3
ELECTRONIC IGNITION CONTROL
CIRCULATING PUMP
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.
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 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
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
FIGURE 4
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.
INSTALLATION INSTRUCTIONS
REQUIRED ABILITY
INSTALLATION OR SERVICE OF THIS WATER HEATER
REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED
TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR
SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK
ARE REQUIRED.
WARNING
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT
IN SERIOUS PERSONAL INJURY OR DEATH.
FIGURE 5
UNCRATING
The “Service Switch” has 2 positions: AUTOMATIC OPERATION
and HOLD OPEN DAMPER. For normal operation the switch
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.
For appliance installation locations with elevations above 2000
feet (610m), refer to HIGH ALTITUDE INSTALLATIONS section
of this manual for input reduction procedure.
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.
LEVELING
If the unit is not level, insert the bolts which were used in crating
into the legs to correct this condition.
CLEARANCES
These heaters are approved for installation on combustible flooring
in an alcove when the minimum clearance from any combustion
construction are followed as indicated in figure 6 and Table 2.
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 floor shall be covered by the panel. Also, see the DRAIN

WARNING
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.
In all installations the minimum combustible clearances from any
draft hood surface or vent piping shall be 6” (16cm). Vent piping
passing through a combustible wall or ceiling must be a continuous
run (no joints) and retain the 6” (16cm) clearance unless an
approved reducing thimble is used.
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 flow.
A service clearance of 24” (61cm) should be maintained from
serviceable parts, such as relief valves, flue baffles, flue damper
devices, thermostats, cleanout openings or drain valves.
ILLUSTRATION OF MINIMUM COMBUSTIBLE CLEARANCES IN AN ALCOVE
FIGURE 6
HARD WATER
ventilation and draft hood dilution must be obtained from outdoors.
The installation instructions for confined spaces in tightly
constructed buildings must be followed to ensure adequate air
supply.
Where hard water conditions exist, water softening or the threshold
type of water treatment is recommended. This will protect the
dishwashers, coffee urns, water heaters, water piping and other
equipment.
CONFINED SPACE
When drawing combustion and dilution air from inside a
conventionally constructed building to a confined 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).
See MAINTENANCE section for details of tank cleanout
procedure.
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.
If the confined 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.
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.
VENT REDUCER
The SBD 250, 251, and 275 models are shipped with an 8” to
6” diameter flue outlet adapter. Each adapter fits on top of the
installed flue damper. Use only vent reducers supplied with the
unit. The venting must comply with the NATIONAL FUEL GAS
CODE, ANSI Z223.1/NFPA 54.
Where an exhaust fan is supplied in the same room with
a heater, sufficient 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.
UNCONFINED SPACE
In buildings of conventional frame, brick, or stone construction,
unconfined spaces may provide adequate air for combustion,
ventilation and draft hood dilution.
If the unconfined space is within a building of tight construction
(buildings using the following construction: weather stripping,
heavy insulation, caulking, vapor barrier, etc.), air for combustion,
FIGURE 7
VENTING
WATER LINE CONNECTIONS
This manual provides detailed installation diagrams (see pages
16-22 of this manual) for typical methods of application for the
water heaters.
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.
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 flow rate
should be slow so that there will be a minimum of turbulence
inside the heater.
Heater must be protected from freezing downdrafts.
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
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.
WATER (POTABLE) HEATING AND
SPACE HEATING
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.
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.
• 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).
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.
FIGURE 8
MULTIPLE HEATER MANIFOLD
SYSTEM CONNECTIONS
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.
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 field 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
HEATER, THE RELIEF VALVE(S) MUST NOT BE REMOVED
OR PLUGGED.

ASME ratings cover pressure relief capacities. ANSI ratings cover
release rate with temperature actuation.
WARNING
THE HEATER IS NOT INTENDED FOR OPERATION AT HIGHER
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 VALVES ARE PROTECTED AGAINST
BLOCKAGE. THESE ARE PARTS OF THE GAS SUPPLY
SYSTEM, NOT THE HEATER. VENT BLOCKAGE MAY OCCUR
DURING ICE STORMS.
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).
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 OUTLET AND MUST
NOT CONTAIN VALVES OR RESTRICTIONS NOR SHOULD IT BE
LOCATED IN FREEZING AREAS. DO NOT THREAD OR CAP THE
END OF THIS LINE. RESTRICTED OR BLOCKED DISCHARGE
WILL DEFEAT THE PURPOSE OF THE VALVE AND IS UNSAFE.
DISCHARGE LINE SHALL BE INSTALLED TO ALLOW COMPLETE
DRAINAGE OF BOTH THE VALVE AND LINE.
IF COPPER SUPPLY LINES ARE USED THEY MUST BE
INTERNALLY TINNED AND CERTIFIED FOR GAS SERVICE.
BEFORE ATTACHING THE GAS LINE, BE SURE THAT ALL GAS
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 READILY ACCESSIBLE
AND NOT SUBJECT TO FREEZING CONDITIONS. INSTALL
IN ACCORDANCE WITH RECOMMENDATIONS OF SERVING
GAS SUPPLIERS. REFER TO THE CURRENT EDITION OF
THE NATIONAL FUEL GAS CODE.
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.
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.
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 current edition of
the National Fuel Gas Code.

BEFORE PLACING THE HEATER IN OPERATION, CHECK FOR
GAS LEAKAGE. Use soap and water solution or other material
acceptable for the purpose in locating the leaks. DO NOT USE
MATCHES, CANDLES, FLAME OR OTHER SOURCES OF
IGNITION FOR THIS PURPOSE.
13
DISCONNECT THE HEATER AND ITS MANUAL GAS SHUTOFF
VALVE FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY
SUPPLY PRESSURE TESTING EXCEEDING 1/2 PSIG (3.45 Kpa).
GAS SUPPLY LINE MUST BE CAPPED WHEN DISCONNECTED
FROM THE HEATER FOR TEST PRESSURES OF 1/2 PSIG (3.45
Kpa) OR LESS. THE APPLIANCE NEED NOT BE DISCONNECTED,
BUT MUST BE ISOLATED FROM THE SUPPLY PRESSURE TEST
BY CLOSING THE MANUAL GAS SHUTOFF VALVE.
Do not subject the combination gas valve to inlet gas pressures of
more than 14.0” W.C. (3.48 Kpa) - natural gas, 14.0” W.C. (3.48
Kpa) - propane gas. A service regulator is necessary if higher gas
pressures are encountered.
Gas pressure specified in Table 5, refer to flow pressure taken at
pressure tap of automatic gas valve while heater is operating.
GROUNDING INSTRUCTIONS
GAS METER SIZE — NATURAL GASES ONLY
This water heater must be connected to a grounded metal,
permanent wiring system; or an equipment grounding conductor
must be run with the circuit conductors and connected to the
equipment grounding terminal or lead on the water heater.
Be sure the gas meter has sufficient capacity to supply the full
rated gas input of the water heater as well as the requirements of
all other gas fired equipment supplied by the meter. If gas meter
is too small, ask the gas company to install a larger meter having
adequate capacity.
HEATER WIRING
GAS PRESSURE REGULATOR
All electrical work must be installed in accordance with the
latest version of the National Electrical Code ANSI/NFPA No. 70,
and must conform to all local code authority having jurisdiction. AN
ELECTRICAL GROUND IS REQUIRED TO REDUCE RISK OF
ELECTRICAL SHOCK OR POSSIBLE ELECTROCUTION.
The gas pressure regulator is built into the gas valve and is
equipped to operate on the gas specified on model and rating
plate. The regulator is factory adjusted to deliver gas to burner
at correct water column pressure allowing for a nominal pressure
drop through the controls.
If any of the original wire as supplied with the appliance must be
replaced, use only type 105°C thermoplastic or equivalent. 2500C
type F must be used for the flame sensor leads and the spark
ignition cable must be high voltage 250°C.
The minimum gas supply pressure for input adjustment must not
be less than 4.5” W.C. (1.12 Kpa) for natural gas and 11.0” W.C.
(2.74 Kpa) for propane gas.

TEMPERATURES ARE NECESSARY TO OBTAIN ADEQUATE
BOOSTER OUTPUT, ADD AN ANTI-SCALD VALVE FOR HOT
WATER SUPPLIED TO FIXTURES.
Cold water lines to heater should be installed as shown in order
to minimize gravity circulation of hot water to building cold water
lines.
A listed temperature and pressure relief valve of adequate capacity
is installed on the heater. The locations shown in the installation
diagrams on the following pages are typical.
The discharge opening of the temperature and pressure relief
valve, located in front of the heater must be piped to an open drain
and should not be subject to freezing temperatures.
TUBE INLET INSTALLATION
Install in accordance with all local codes.
Use of the top inlet water connection requires installation of an inlet
dip tube (refer to figure 12). The tube is supplied in the heater.
Follow caution labels if applying heat to this fitting. Do not allow
pipe dope to contact the plastic tube during installation.
CODE RESTRICTIONS
Use of the top inlet water connection is not permitted on
installations in the state of North Carolina, due to the material of
the tube (Polypropylene). Where such code restrictions exist, use
only lower inlet tank connection. This may also require a heat

adjustments and avoid unnecessary service calls. However, the
user should not attempt repairs which are not listed under the
USER column.
WARNING
THE GAS VALVE MUST HAVE BEEN IN THE OFF POSITION FOR
AT LEAST 5 MINUTES. This waiting period is an important safety
step. Its purpose is to permit gas that may have accumulated in the
combustion chamber to clear. IF YOU DETECT GAS ODOR AT THE
END OF THIS PERIOD DO NOT PROCEED WITH LIGHTING.
RECOGNIZE THAT GAS EVEN IF IT SEEMS WEAK, MAY
INDICATE PRESENCE OF ACCUMULATED GAS SOMEPLACE
IN THE AREA WITH RISK OF FIRE OR EXPLOSION. SEE THE
FRONT PAGE FOR STEPS TO BE TAKEN. All gas and water
lines are to have been leak tested and open to the respective gas
and water supplies.

Valves for reducing point-of-use temperature by mixing cold and
hot water are available. Also available are inexpensive devices
that attach to faucets to limit hot water temperatures. Contact a
licensed plumber or the local plumbing authority.
ADJUSTMENTS
ON INITIAL STARTUP SOME ADJUSTMENTS ARE NECESSARY.
1. CHECK MANIFOLD AND 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 the AUTOMATIC 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 TEMPERATURE AT WHICH INJURY OCCURS
VARIES WITH THE PERSON’S AGE AND TIME OF EXPOSURE.
THE SLOWER RESPONSE TIME OF CHILDREN, AGED OR
DISABLED PERSONS INCREASES THE HAZARDS TO THEM.
NEVER ALLOW SMALL CHILDREN TO USE A HOT WATER
TAP, OR DRAW THEIR OWN BATH WATER. NEVER LEAVE A
CHILD OR DISABLED PERSON UNATTENDED IN A BATHTUB
OR SHOWER.
• 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 GENERAL PUBLIC DOES NOT HAVE ACCESS
TO SET TEMPERATURES.
If the water heater does operate when placed in the HOLD OPEN
DAMPER position:
SETTING THE WATER HEATER TEMPERATURE AT 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 TROUBLESHOOTING 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 lower
temperature settings to reduce scald hazards.

CHECKING VENTING
The following steps shall be followed with each appliance
connected to the venting system placed in operation, while any
other appliances connected to the venting system are not in
operation.
27
1. Seal any unused openings in the venting system.
• The pilot flame should envelop sensing device with 5/8”
(1.6cm) flame, fig. 15. Remove pilot adjustment cover
screw, fig. 16. Turn inner adjustment screw clockwise to
decrease, or counterclockwise to increase pilot flame. Be
sure to replace cover screw on gas valve after adjustment
to prevent possible gas leakage.
2. Inspect the venting system for proper size and horizontal pitch,
as required in the National Fuel Gas Code, ANSI Z223.1 and
these instructions. Determine that there is no blockage or
restriction, leakage, corrosion and other deficiencies which
could cause an unsafe condition.
2. Clogged pilot burner orifice.
3. So far as is practical, close all building doors and windows and all
doors between the space in which the water heater(s) connected
to the venting system are located and other spaces of the building.
Turn on all appliances not connected to the venting system. Turn on
all exhaust fans, such as range hoods and bathroom exhausts, so
they shall operate at maximum speed. Close fireplace dampers.
• Clean or replace orifice. A clogged orifice will restrict gas
flow.
3. Incorrect orifice.
• Replace. See Table 7, for correct orifice for type of gas used.
Orifice size is stamped on the wrench flats.
4. Follow the lighting instruction. Place the water heater being
inspected in operation. Adjust thermostat so appliance shall
operate continuously.
5. Test for draft hood spillage at the relief opening after 5 minutes
of main burner operation.
6. After it has been determined that each appliance connected
to the venting system properly vents when tested as outlined
above, return doors, windows, exhaust fans, fireplace dampers
and any other gas burning appliance to their previous conditions
of use.
7. If improper venting is observed during any of the above tests,
the venting system must be corrected.
FIGURE 13
WARNING
FAILURE TO CORRECT BACK DRAFTS MAY CAUSE AIR
CONTAMINATION AND UNSAFE CONDITIONS.
Pilot sensing device must sense a flame before sparking will stop.
Loose wires or a draft may cause intermittent or abnormal sparking.
To eliminate this condition, first correct loose wiring condition, and
then, if necessary, increase pilot flame.
• 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. 14, and the main
burner, fig. 15, 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.
FIGURE 14
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:
Pilot burner flame is affected by:
• Cause rapid ignition and carry over of flame across entire
burner.
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. 16.
• Cause no excessive lifting of flame from burner ports.
28
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.
FIGURE 15
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.
Btuh = Actual heater input.
Example: (Using SBD-240 heater)
T = 15.8 seconds
H = 1050 Btu
GAS VALVES
Btuh = ?
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)
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.
Also check for good flow of combustion and ventilating air to the
unit. Maintain a clear area around the heater at all times.
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. 16, and
adjust the pressure by turning the adjusting screw with a
screwdriver.

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.

VENTING SYSTEM
the factory installed magnesium anodes with aluminum anodes
may correct the condition.
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 SHUT OFF, TURN OFF THE MANUAL GAS CONTROL VALVE
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.

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
TEMPERATURE AND 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.

7. Replace outer jacket cover plate.
FIGURE 17
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 glasslined tanks.
CAUTION
Observe handling instructions on label of product being used.
DELIMING USING FLO-JUG METHOD
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) 821-2017
Fax: (800) 433-2515
Website: www.statewaterheaters.com
Prepare the Water Heater
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.
2. A cleanout opening is provided for periodic cleaning of the
tank. Gas must be shut off and heater drained before opening
cleanout.
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.
31
— Check that “main manual gas shutoff valve” is fully open and
that gas service has not been interrupted.
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 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.
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.
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.
ELECTRICAL SERVICING
8. Let UN•LIME remain in the heater for 5 minutes and then lower
the container to the “Drain” Position, see Figure 9.
9. Deliming activity is indicated by foaming on the surface of the
UN•LIME. If there is deliming activity, repeat steps 6 thru 8.
CAUTION
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN
SERVICING CONTROLS. WIRING ERRORS CAN CAUSE
IMPROPER AND DANGEROUS OPERATION.
Normally, lime removal will be completed within one hour. Severe
build-up of lime may take longer than an hour to complete
descaling.
VERIFY PROPER OPERATION AFTER SERVICING.
Note: To check UN•LIME for continued use, place some scale
or white chalk in a glass with a small amount of UN•LIME. If the
material is vigorously dissolved by the UN•LIME, it can be reused;
if not, the UN•LIME should be replaced.

is working properly.
2.Defective component in appliance after the flue damper.
3.If 24 VAC is not present at the ignition module, look for loose or broken
connections between damper and ignition module.
4. If the connections from damper to ignition module seem proper, replace damper assembly. If a damper assembly is not available, place the service switch in the
hold open position. This should keep the damper in the open position and allow
the customer to have automatic heat, until a replacement damper can be installed.
C. DAMPER ROTATES CONTINUOUSLY

OPERATIONAL CHECKLIST
This checklist in conjunction with “TROUBLESHOOTING” and the “SEQUENCE OF OPERATION” should be used as an on-the-job
troubleshooting guide to identify the cause of incorrect system operation and suggest a remedy for its correction. Because improper
piping and wiring can result in unsatisfactory system performance, it is suggested that the installation by examined before using the
checklist. Be sure to refer to the correct piping and wiring diagram for the type of system that is installed.
