GENERAL SAFETY
INFORMATION
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.
PRECAUTIONS
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.
DO NOT USE THIS APPLIANCE IF ANY PART HAS 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.
IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT
OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE
BEEN MADE BY A QUALIFIED SERVICEMAN.
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 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.
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.
4. SOOTING
CHEMICAL VAPOR CORROSION
EXTENDED NON-USE PERIODS
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.
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 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 are 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
IMPROPER COMBUSTION
Insulation blankets available to the general public for external
use on gas water heaters are not approved for use on your
American water heater. The purpose of an insulation blanket is
to reduce the standby heat loss encountered with storage tank
water heaters. Your American water heater meets or exceeds
the ANSI/ASHRAE/IESNA Standard 90.1 2004 with respect to
insulation and standby loss requirement making an insulation
blanket unnecessary.
WARNING
ATTIC AND/OR EXHAUST FANS OPERATING 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.
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 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 OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION AND
VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.
• Do not cover the gas valve or temperature & pressure relief
valve.
4
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.
• 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” (5 cm) of the
burners, to prevent blockage of combustion air flow to the
burners.
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.
• Do not allow insulation to come within 9” (23 cm) of floor, (within
2” (5 cm) of bottom cover) to prevent blockage of combustion
air flow to the burners.
FEATURES
• Do inspect the insulation blanket frequently to make sure it
does not sag, thereby obstructing combustion air flow.
(Self-Cleaning System)
• Do obtain new labels from American Water Heater for placement
on the blanket directly over the existing labels.
These units include self-cleaning device (Self-Cleaning
System) installed in the front water inlet. See figure 2. The
Eliminator must be oriented correctly for proper function. There
is a marked range on the pipe nipple portion of the Eliminator,
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
Eliminator to reduce the probability of misaligning the Eliminator
accidentally while tightening the connection to the inlet water
supply line. Improper orientation of the Eliminator can cause
poor performance of the heater and can significantly reduce
outlet water temperatures during heavy draws.
HIGH ALTITUDE INSTALLATIONS
WARNING
INSTALLATIONS ABOVE 2000 FEET (610 METERS) REQUIRE
REPLACEMENT OF THE BURNER ORIFICES IN ACCORDANCE
WITH THE CURRENT EDITION OF 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
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.
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.
NOTE: The inlet tube may have 1, 3 or 7 cross-tubes.
Ratings specified by manufacturers for most appliances apply for
elevations up to 2000 feet (610 m). For elevations above 2000
feet (610), ratings must be reduced at the rate of 4% for each
1000 feet (305 m) 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 (1219 m), 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 (121.9 m): 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 (1829 m) the correct input rating should be 91,200
Btuh (26.7 Kwh).
FIGURE 2
For proper function, The Eliminator 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 Eliminator to help eliminate the
possibility of changing the orientation by accidentally overtightening the inlet supply line. Improper orientation of The
Eliminator may cause temperature build-up issues or spells of
colder than usual water temperatures.
HIGH LIMIT SWITCH
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 American Water Heater
Company. When ordering, be sure to state the model number
and the altitude of the location where the water heater is
being installed.
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.
5
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:
Each automatic flue damper drive assembly is equipped with a
“Service Switch”, as shown in figure 5.
• 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.
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.
DIGITAL THERMOSTAT
FIGURE 3
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.
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 current edition of
the National Electrical Code NFPA 70.
Only all bronze circulators should be used with commercial water
heaters.
Although circulating pumps 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
9003425205.
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
AUTOMATIC FLUE DAMPER DEVICE
All units are equipped with an automatic flue damper that
reduces heat loss during the OFF cycles.
6
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.
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.
INSTALLATION INSTRUCTIONS
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.
THE HEATER MUST NOT BE LOCATED IN AN AREA WHERE
IT WILL BE SUBJECT TO FREEZING.
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.
When such locations cannot be avoided, it is recommended that
a suitable metal drain pan, adequately drained, be installed under
the appliance.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage may
result in property damage, even with the use of a drain pan piped
to a drain. However, unanticipated damage can be reduced or
prevented by a leak detector or water shut-off device used in
conjunction with a piped drain pan. These devices are available
from some plumbing supply wholesalers and retailers, and detect
and react to leakage in various ways:
WARNING
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT
IN SERIOUS PERSONAL INJURY OR DEATH.
UNCRATING
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.
• Sensors mounted in the drain pan that trigger an alarm or turn
off the incoming water to the water heater when leakage is
detected.
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.
• Sensors mounted in the drain pan that turn off the water supply
to the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water
pipes connected to the water heater.
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” (.50 m). OR MORE ABOVE THE
FLOOR. THIS MAY REDUCE THE RISK IF LOCATION IN SUCH
AN AREA CANNOT BE AVOIDED.
• Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.
WHEN SUCH LOCATIONS CANNOT BE AVOIDED, A SUITABLE
METAL DRAIN PAN SHOULD BE INSTALLED UNDER THE
HEATER. Such pans should be fabricated with sides at least 2” (5
cm) deep, with length and width at least 2” (5 cm) greater than the
diameter of the heater and must be piped to an adequate drain.
The pan must not restrict combustion air flow.
LEVELING
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 (7.6 cm) 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
REQUIREMENTS.
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.
THE HEATER SHALL BE LOCATED OR PROTECTED SO IT IS NOT
SUBJECT TO PHYSICAL DAMAGE BY A MOVING VEHICLE.
WARNING
The following units are approved for installation with side, rear
and ceiling clearances as indicated below:

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.
TABLE 2
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.
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.
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.
HARD WATER
UNCONFINED SPACE
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.
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,
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.
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.
8
CONFINED SPACE
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.
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).
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.
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.
• 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.
VENT REDUCER
The BCG3100T2508N, BCG365T2508N, & BCG3100T2758N all
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.

WARNING
WATER LINE CONNECTIONS
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.
This manual provides detailed installation diagrams (see pages
16-22 of this manual) for typical methods of application for the
water heaters.
Heater must be protected from freezing downdrafts.
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.
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

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.
WARNING
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.
Your local code authority may have other specific relief valve
requirements.
3. This unit may NEVER be connected to any existing heating
system or component(s) previously used with a non-potable
water heating appliance.
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, 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.
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 15 through 20 in this manual for suggested
piping arrangements.
CAUTION
As water is heated, it expands (thermal expansion). In a closed
system, the volume of water will grow. As the volume of water
grows, there will be a corresponding increase in water pressure
due to thermal expansion. Thermal expansion can cause
premature tank failure (leakage). This type of failure is not
covered under the limited warranty. Thermal expansion can also
cause intermittent temperature-pressure relief valve operation:
water discharged from the valve due to excessive pressure build
up. The temperature-pressure relief valve is not intended for the
constant relief of thermal expansion. This condition is not covered
under the limited warranty.
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.
A properly-sized thermal expansion tank should be installed
on all closed systems to control the harmful effects of thermal
expansion. Contact a plumbing service agency or your retail
supplier regarding the installation of a thermal expansion tank.
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.
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.

RECOMMENDATIONS OF SERVING GAS SUPPLIERS.
REFER TO THE CURRENT EDITION OF THE NATIONAL
FUEL GAS CODE.
WARNING
THE HEATER IS NOT INTENDED FOR OPERATION AT
HIGHER THAN 14.0” W.C.(3.5 kPa) (1/2 POUND PER SQUARE
INCH GAGE- 3.5 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.
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.
GAS PIPING AND DIRT LEG INSTALLATION
IT IS IMPORTANT TO GUARD AGAINST GAS VALVE FOULING
FROM CONTAMINANTS IN THE GAS WAYS. SUCH FOULING
MAY CAUSE IMPROPER OPERATION, FIRE OR EXPLOSION.
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. 11). THE DIRT LEG MUST BE
FIGURE 11
FIGURE 12
13
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.
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.
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.
DISCONNECT THE HEATER AND ITS MANUAL GAS
SHUT-OFF VALVE FROM THE GAS SUPPLY PIPING
SYSTEM DURING ANY SUPPLY PRESSURE TESTING
EXCEEDING 1/2 PSIG (3.5 kPa). GAS SUPPLY LINE
MUST BE CAPPED WHEN DISCONNECTED FROM
THE HEATER FOR TEST PRESSURES OF 1/2 PSIG
(3.5 kPa) OR LESS. THE APPLIANCE NEED NOT BE
DISCONNECTED, BUT MUST BE ISOLATED FROM THE
SUPPLY PRESSURE TEST BY CLOSING THE MANUAL GAS
Shut-off VALVE.
Gas pressure specified in Table 5, refer to flow pressure taken at
pressure tap of automatic gas valve while heater is operating.
GROUNDING INSTRUCTIONS
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.
GAS METER SIZE — NATURAL GASES ONLY
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
All electrical work must be installed in accordance with the current
edition of the National Electrical Code NFPA 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 (see FIGURE 12).
GAS PRESSURE REGULATOR
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. 250°C
type F must be used for the flame sensor leads and the spark
ignition cable must be high voltage 250°C.
INSTALLATION DIAGRAMS-TOP INLET/OUTLET USAGE
GENERAL
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
trap - check local codes. The “Top Outlet” connection may still be
used on these applications. Plug or cap all unused openings in
the tank before filling with water.
The type, size and location of the relief valves must be in
accordance with local codes. The locations of the relief valves
shown in the installation diagrams are typical. The heater has a
factory installed high temperature limit switch and temperature
and pressure relief valve.
Cold water lines to heater should be installed as shown in order
to minimize gravity circulation of hot water to building cold water
lines.

OPERATION
PURGING
Gas line purging is required with new piping or systems in which
air has entered.
IMPORTANT
A qualified person must perform the initial firing of the heater. At
this time the user should not hesitate to ask the individual any
questions which they may have in regard to the operation and
maintenance of the unit.
CAUTION
PURGING SHOULD BE PERFORMED BY PERSONS
EXPERIENCED IN THIS TYPE GAS SERVICE. TO AVOID RISK OF
FIRE OR EXPLOSION, PURGE DISCHARGE MUST NOT ENTER
CONFINED AREAS OR SPACES WHERE IGNITION CAN OCCUR.
THE AREA MUST BE WELL VENTILATED AND ALL SOURCES OF
IGNITION MUST BE INACTIVATED OR REMOVED.
An Operational Checklist is included at the rear of this manual. By
using this checklist the user may be able to make minor operational
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 leak tested and open.
GENERAL

SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL
TO SHUT OFF, TURN OFF THE MANUAL GAS CONTROL VALVE
TO THE APPLIANCE.
With above conditions satisfied, light the unit in accordance with
the instructions on the Operating label attached to the heater. If
label instructions are not legible - determine which gas valve the
appliance is equipped with and use the applicable OPERATING
INSTRUCTIONS as follows:
CAUTION
Before proceeding with the operation of the unit make sure
the water heater and system are filled with water and all air is
expelled.
IF PILOT FLAME GOES OUT - Main burners will extinguish and
pilot will attempt reignition.

ADJUSTMENTS
that attach to faucets to limit hot water temperatures. Contact a
licensed plumber or the local plumbing authority.
ON INITIAL STARTUP SOME ADJUSTMENTS ARE NECESSARY.
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.
1. CHECK MANIFOLD AND INLET GAS PRESSURES.
2. TO ADJUST PILOT FLAME - FOLLOW “PILOT BURNER”
PROCEDURE UNDER “PREVENTIVE MAINTENANCE”.
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.
WATER TEMPERATURE CONTROL
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
• The damper disc must be open (in the vertical position) before
the ignition and combustion process begins.
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 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.
SETTING THE WATER HEATER TEMPERATURE AT 120°F WILL
REDUCE THE RISK OF SCALDS. Some states or provinces
require settings at specific lower temperatures.
If the water heater does operate when placed in the HOLD OPEN
DAMPER position:
• 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
If you experience this type of use, you should consider using lower
temperature settings to reduce scald hazards.
Do not force the damper disc manually or motor damage will
occur.

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.
Valves for reducing point-of-use temperature by mixing cold and
hot water are available. Also available are inexpensive devices
1. Seal any unused openings in the venting system.
25
• The pilot flame should envelop sensing device with 5/8”
(1.6cm) flame, fig. 16. Remove pilot adjustment cover screw,
fig. 15. 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 current edition of 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.
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.
2. Clogged pilot burner orifice.
•
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.
WARNING
FIGURE 14
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. 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.
FIGURE 15
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. 16, 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. 17.
• Cause no excessive lifting of flame from burner ports.
26
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 16
If the preceding burner characteristics are not evident, check
for accumulation of lint or other foreign material that restricts or
other foreign material that restricts or blocks the air openings to
the burner or heater.
1. Attach a pressure gauge or a manometer to the gauge port and
refer to Table 5, for correct manifold pressure.
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
T = Time in seconds to burn one cubic foot of gas.
H = Btu’s per cubic foot of gas.
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 BTRC-199 heater)
T = 15.8 seconds
GAS VALVES
H = 1050 Btu
Btuh = ?
19.0 X 1050 = 199,000 Btuh (70.3 Kwh) (Compare with
15.9 heater model and rating)
2. Check that burner venturi and ports are free of foreign
matter.
3. Clean burners with bristle brush and/or vacuum cleaner — DO
NOT distort burner ports or pilot location.
Figure 17 shows the two types of combination gas control valves
used on these heaters.
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.
LP VALVE
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.
NATURAL VALVE
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.

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 16.
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 consumption.
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

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
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.
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.
WARNING

Such costs may include but are not limited to:

5. LIMITATIONS ON IMPLIED WARRANTIES
Implied warranties, including the warranty of merchantability imposed on the sale of this heater under state or provincial law are limited to one (1)
year duration for the heater or any of its parts. Some states and provinces do not allow limitation on how long an implied warranty lasts, so the
above limitation may not apply to you.
6. CLAIM PROCEDURE

this is not practicable, the owner should contact:
U.S. Customers

CONSEQUENTIAL DAMAGE. THE WARRANTOR SHALL NOT BE LIABLE BY VIRTUE OF THIS WARRANTY OR OTHERWISE FOR DAMAGE TO ANY
PERSONS OR PROPERTY, WHETHER DIRECT OR INDIRECT, AND WHETHER ARISING IN CONTRACT OR IN TORT.
