INSTALLATION
WARNING
!
Read and review this entire manual with special
emphasis on the Venting Sections and Operation
Sections prior to any installation work.
LOCAL INSTALLATION REGULATIONS
This water heater must be installed in accordance with
these instructions, local codes, utility company requirements, and/or in the absence of local codes, the latest
edition of the American National Standard / National Fuel
Gas Code, a copy of which can be purchased from either
American Gas Association, 1515 Wilson Blvd., Arlington,
VA 22209 as booklet Z223.1 or National Fire Prevention
Association, 1 Batterymarch Park, Quincy, MA 02269 as
booklet NFPA 54.
The water heater must be located or protected so it is not
subject to physical damage, for example, by moving
objects, area flooding, etc.
CAUTION
!
The water heater should not be located in an area
where leakage of the tank or connections will result
in damage to the area adjacent to it or to lower floors
of the structure. When such areas cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the water heater.
The pan MUST NOT restrict the flow of combustion
air flow.
NOTE: Auxiliary catch pan installation MUST conform to the applicable local codes
service clearance minimum. This front service may be
achieved by a non-rated or combustible door or access
panel; providing the 24" service clearance is achieved
when the door is opened or panel is removed. This water
heater must not be located near flammable liquids
such as gasoline, adhesives, solvents, paint thinners, butane, liquefied propane, etc. as the controls
of this appliance could ignite those vapors, causing
an explosion.
TEMPERATURE AND PRESSURE RELIEF VALVE
A new combination temperature and pressure relief
valve, complying with the Standard for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22, must be installed in the opening
provided on the water heater at the time of installation.
No valve is to be placed between the relief valve and the
water heater. For circulating tank installation, the separate storage tank(s) must have similar protection. The
pressure rating of the relief valve must not exceed the
maximum working pressure as marked on the front of the
water heater. The Btu/h rating of the relief valve must
equal or exceed the Btu/h input of the water heater as
noted on its rating plate. Connect the outlet of the relief
valve to a suitable open drain. The discharge line must
pitch downward from the valve to allow complete draining
(by gravity) of the relief valve and discharge line, and
must be no smaller than the outlet of the relief valve. The
end of the discharge line should not be threaded or concealed and should be protected from freezing. No valve
of any type, restriction or reducer coupling should be
installed in the discharge line. Local codes shall govern
the installation of the relief valves.
LOCATION
Choose a location for your water heater centralized to the
piping system, along with consideration to vent pipe
length. As the length of vent pipe increases, the firing
rate of the appliance decreases. You must also locate
the Advantage Plus where it will not be exposed to below
freezing temperatures. Additionally, you will need to
place the water heater so that the controls, drain,
inlet/outlet, and gas valve are easily accessed. This
appliance must not be installed outdoors, as it is certified
as an indoor appliance, and must be kept vertical and on
a level surface. Also, care must be exercised when
choosing the location of this appliance where leakage
from the relief valve, leakage from related piping, or leakage from the tank or connections, will not result in damage to the surrounding areas or to the lower floors of the
building. A water heater should always be located in
an area with a floor drain or installed in an adequately drained catch pan suitable for water heaters.
Proper clearance must be provided around the
AdvantagePlus as follows: Sides, bottom, top, and back
are 0" (zero clearance). Front of the appliance needs 24"
EXPANSION TANK
A potable hot water expansion tank may be required to
offset the water expansion as the water is heated. In
most city plumbing systems, the water meter has a no
return or back flow device built into the system to prevent
back flowing of water back into city mains. Back flow preventers may be found on all incoming water supplies.
Under these circumst
expansion tank listed for potable water use. The expansion tank should be located on the cold inlet piping close
to the water heater. The expansion tank must be suit-
able for hot potable water.
WARNING
!
The manufacturer’s warranty does not cover any
damage or defect caused by installation or attachment or use of any special attachments such as energy saving devices (other than those authorized by
the manufacturer) into, onto, or in conjunction with
the water heater. The use of such unauthorized

devices may shorten the life of the water heater and
may endanger life and property. The manufacturer
disclaims any responsibility for such loss or injury
resulting from the use of such unauthorized devices.
DOMESTIC WATER CONNECTIONS
The water connections must be installed in accordance
with all national and local plumbing codes, or any prevailing standard. NEVER USE DIELECTRIC UNIONS
OR GALVANIZED STEEL FITTINGS ON ADVANTAGE
PLUS CONNECTIONS. The inlet and outlet connections
are 1" on the 45 gallon models and 1-1/2" on the 80 and
119 gallon models. On the cold inlet, install a 1" brass
tee on the 45 gallon models, or a 1-1/2" brass tee on the
80 and 119 gallon models. On the run of the 1" brass tee
install, with pipe sealant, compound a 1" brass drain cock
or it's equivalent (not supplied). Into the branch of the 1"
or 1-1/2" brass tee install a copper male adapter to match
with the copper plumbing system. For convenience, you
may install a shut off valve and a union in the cold inlet
piping to ease servicing in the future. If there is a back
flow preventer, or any type of a no return valve in the system, then you must install an additional tee for a suitable
potable thermal expansion tank.(See section on
Expansion Tank.) In the hot outlet connection, (top left),
install a suitable adapter to match the copper tubing of
the plumbing system. A thermal trap or heat trap loop
may be installed here to provide additional energy savings and prevent thermal siphoning of domestic hot
water. A domestic hot water tempering/ anti-scald valve
should be installed into the hot water line to prevent the
maximum outlet water temperature from exceeding 125°
Fahrenheit to prevent scald injury.
SPECIAL INSTRUCTIONS FOR BOOSTER
INSTALLATIONS
All booster heaters are supplied with the "Booster
Installation" kit. In order to maintain proper temperature,
this kit must be correctly installed. The Booster kit contains the following list of parts:
See the following drawing for a typical "Booster" installation. Please note that those items marked with an asterisk in the drawing are not included with the Booster kit,

booster to the dishwasher, and the length of time between washes, it
may be necessary to run an empty rack to purge the supply line of
water that has cooled below 180ºF. For this reason it is best to locate
the booster as close as possible to the dishwasher. The circulator is
equipped with three speeds to increase flow rate and reduce heat

WARNING
!
Tank MUST be full of water before power is turned
on. Heat exchanger coil WILL BE DAMAGED if energized even for a short time while the tank is dry. The
water heater’s warranty does not cover damage or
failure resulting from operation with an empty or partially empty tank. (Reference is made to the limited
warranty for complete terms and conditions)
ELECTRICAL CONNECTION
The electrical connection for the AdvantagePlus is on the
left side of the combustion shroud. There is a 1/2" knockout location for electrical connection. All electrical wiring
must be performed by a qualified licensed electrician,
and in accordance with National Electrical Code, or to the
applicable local codes and standards. The electrical
requirements are for standard 120 volts, 60 Hz., 10 amp
service. It is recommended that an electrical disconnect
switch be placed near the water heater, and that the connection to the AdvantagePlus be made using 3/8" extraflex, or 3/8" greenfield (or equivalent). This unit must be
wired with #14 AWG, and fused for no more than 15
amps.
properly grounded! Ground the water heater by con-
necting the green wire in the electrical access compartment directly to the main building ground system. It is
very important that the building system ground is
inspected by a qualified electrician prior to making
this connection.Once all connections have been
made, the electrical access may be closed. It is very
important that the electrical power is not turned on until
gas and venting connections are completed and the tank
is full of water.
A green LED is provided on the main control board.
This LED must be illuminated when appliance is
turned on for proper operation. Failure to illuminate
means bad or missing ground or reverse polarity.
GAS CONNECTION
Gas supply shall not exceed a maximum inlet pressure of
14" water column (350 mm), 1/2 pound pressure (3.4
kPa), and a minimum of 7" water column (natural and
propane). The entire piping system, gas meter, and regulator must be sized properly to prevent a pressure drop
greater than 0.5" of water column as stated in the
National Fuel Gas Code. Gas pressure information is
listed on the rating plate. It is very important that you
are connected only to the type of gas noted on the
rating plate; "LP" or propane gas or "Nat" natural
gas or city gas. All gas connections must be approved
by the local gas supplier or utility in addition to the governing authority prior to turning the gas supply on. The
nipple provided for the inlet gas connection is 1/2", and it
is mandatory that a 3/4" to 1/2" reducing bushing (provided) is used, threaded into the branch of a 3/4" tee, and
a drip leg fabricated, as per the National Fuel Gas Code.
It is of extreme importance that this unit be
You must ensure that the entire gas line to the reducing bushing connection at the Advantage Plus is no
smaller than 3/4".
CAUTION
!
THE USE OF FLEXIBLE GAS CONNECTORS IS NOT RECOMMENDED. HOWEVER, IF USED, IT IS IMPERATIVE THAT THEY ARE
SIZED CORRECTLY. FLEXIBLE GAS CONNECTORS MUST HAVE A
MINIMUM ID OF 3/4". A MINIMUM 3/4" ID MUST BE MAINTAINED
TO AVOID RESTRICTION OF GAS FLOW! NEVER REDUCE THE
GAS SUPPLY LINE BELOW 3/4"!
Once all the inspections have been performed, the piping
system must be leak tested. If the leak test pressure is
higher than the maximum permissible inlet pressure, you
must isolate the AdvantagePlus from the gas line before
testing. In order to do this, you must disconnect the
union and cap the inlet gas line. In the event the gas
valve is exposed to a pressure greater than 1/2 PSI, 14"
water column, the gas valve must be replaced.
Failure to follow all precautions could result in fire,
explosion or death! It is recommended that a soapy
solution be used to detect leaks. Bubbles will appear and
indicate a leak is present. The gas piping must be sized
for the proper flow and length of pipe to avoid unacceptable pressure drop. Both the gas meter and the gas regulator must be properly sized for the total gas load. If you
experience a pressure drop greater than 1" W.C., the
meter or regulator or gas line may be undersized or in
need of service. On the inlet side of the gas valve, there
is a 1/8" NPT plug. This plug can be removed to attach a
manometer. You can attach a meter to the incoming gas
drip leg by removing the cap and installing the meter. The
gas pressure must remain between 7" and 14" of water
column during stand-by and unit running heat cycle. If an
in-line regulator is used, it must be a minimum of 10 feet
from the AdvantagePlus. It is very important that the
gas line is properly purged by the gas supplier or
utility. Failure to properly purge the lines or improper line sizing, will result in the failure of the
AdvantagePlus lighting off. The gas valve is a special
gas valve which has a Pressure Augmented Regulator
feature, as well as negative outlet pressure. This valve
must not be replaced with a conventional valve under any
circumstances. Make sure valve is in the “OFF” position
prior to turning gas supply on. As an additional safety
feature, this valve has a left hand thread on the outlet
end, and a special tamper resistant electrical connector.
WARNING
!
Never use open flame to test for gas leaks, as
bodily injury or property damage could result.
WARNING
!
DO NOT exceed input shown on water heater rating
plate.

VENTING WHEN USING 3" VENT PIPE
(ONLY MODELS WITH INPUTS OF 100,000 BTU AND 130,000 BTU
ARE CERTIFIED TO USE 2" VENT PIPE, SEE SPECIAL VENTING
INSTRUCTIONS SECTION)
For inlet air supply, top pipe on the right of the shroud,
use 3" PVC schedule 40. It is very important that you plan
the location properly to eliminate long pipe runs and
excessive fittings. Inlet pipe size must not be reduced.
Do not combine the inlet air with any other inlet pipe
including an inlet to an additional similar appliance.
The joints must be properly cleaned, primed, and
cemented. The piping must also be properly supported
as per local and national standard plumbing codes. It is
important that the piping be clean and free from burs,
debris, ragged ends, and particles of PVC.
For exhaust piping, lower pipe on the right of the shroud,
use only ABS schedule 40 or CPVC schedule 40 or 80,
NON FOAM CORE
, in the first 84" (7 feet) of vent length.
The balance of the inlet and exhaust piping may be PVC
schedule 40, ABS schedule 40 or CPVC schedule 40 or
80, NON FOAM CORE ONL
Y, as required to meet local
venting codes.
Exhaust piping should be sloped back to the connection
on the AdvantagePlus, at least 1/4 inch per foot of pipe,
to remove the condensate that forms within the pipe. The
total combined length of pipe, (inlet air piping plus
exhaust piping) including allowances for elbows, should
not exceed 85 equivalent feet. The total combined length
of pipe, including allowances for elbows, should not be
less than 22 equivalent feet (minimum length of 12 feet of
piping, including allowances for elbows, on the inlet and
the exhaust). Choose your vent termination locations
carefully. You must make certain that exhaust gas does
not re-circulate back into the air inlet pipe. You must
place your vent terminations in an open area, according
to the following guidelines.
V
enting Guidelines
1) Never vent into a walkway or patio area, or an alley,
or otherwise public area less than 7' from the ground.
2) Allow four (4) feet below or four (4) feet horizontally
from any door, window or gravity air inlet to the building
or other appliance.
3) Never install a heat saver or similar product to capture waste heat from exhaust.
4) Always have vent location at least 1' above maximum
snow level.
5) Always have vent 1' above ground level, away from
shrubs and bushes.
6) Follow local gas codes in your region or refer to
National Fuel Gas Code, or Can B149.
7) Always have vent at least 3' from an inside corner of
outside walls.
8) Maintain at least 4' clearance to electric meters, gas
meters and exhaust fans or inlets.
9) Inlet air must be taken from outside of building next
to exhaust outlet, no closer than 8".
10) Always place 1/2 inch x 1/2 inch 16 gauge galvanized steel screen in the intake and exhaust openings to
prevent foreign matter from entering the AdvantagePlus.
11) The vent system must be balanced by friction loss
equivalent (See table on page 10).
12) The same method must be used for both intake and
exhaust termination. DO
NOT terminate one horizontal-
ly and the other vertically.
13) Roof Venting: The vent intake and exhaust must be
properly cleaned and glued, for pressure tight joints.
Several methods for venting the AdvantagePlus can be
found on pages 22 and 23. Use the layout as a guideline. Certain site conditions such as multiple roof
lines/pitches may require venting modifications-consult
factory. The air inlet must be a minimum of 1' vertically
above the maximum snow level or 24" whichever is
greater. The air inlet must also be a minimum of 10' horizontally from the roof and terminated with a tee. The
exhaust must be a minimum of 24" above the air inlet
opening and terminated with a coupling. It is very important that there are no other vents, chimneys, or air inlets
in any direction for at least 4'.All venting must be
properly supported, as the AdvantagePlus is not
intended to support any venting whatsoever. All pip-
ing, glue, solvents, cleaners, fittings, and components
must conform to ASTM (American Society for Testing and
Materials), and ANSI (American National Standard
Institute).
14) It is recommended that you use vent kits specifically
designed for AdvantagePlus installations.
PIPE / FITTINGS WHEN USING 3” VENT PIPE
The first 84" (7’) of exhaust piping, must be of 3" ABS
solid only (provided) or CPVC; (NEVER use cellularfoam core pipe on exhaust piping), and conform to
ASTM D-3965 for ABS or ASTM F-441 for CPVC, and fittings to ASTM D2661 & D3311 for ABS and ASTM F-439
for CPVC. The balance of exhaust piping, and all of
intake piping, use standard 3" PVC schedule 40 or 3"
ABS schedule 40, conforming to ASTM D2665, or ABS
conforming to ASTM D-3965 & ASTM R-441 for ABS; and
fittings conforming to ASTM D-2665 & D331. ABS may
also be used for intake venting as long as pipe conforms
to ASTM D3965 & D2661 and fittings meet ASTM D2661
& D3311.
FOR LONGER VENT LENGTHS WHEN USING 3”
VENT PIPE
All venting must be 3", both intake and exhaust. NEVER
use any piping less than 3", or different size pipe on
the intake and exhaust. You may use 4" venting on
both intake and exhaust to lower the pressure drop and
provide additional venting length. It is imperative when
using 4" venting to follow these instructions very
carefully. For longer venting lengths, the first 10' of
both the intake and exhaust piping are 3". For the
intake, use 10' of 3" PVC plus one 90 degree or two
45 degree elbows. For the exhaust, use 10' of ABS
solid NON FOAM CORE, or CPVC plus one 90 degree
8
or two 45 degree elbows. Then use a 4" x 3" PVC or 4"
x 3" ABS reducing coupling. Then proceed with PVC 4"
NON FOAM CORE pipe and fittings for both the intake
and exhaust piping. On 4" piping you may go an additional 125 equivalent feet of pipe and fittings, combined
total length. The 4" fittings have a friction loss allowance
as follows:
4" 90 degree = 3' and a 4" 45 degree = 1'.
The total maximum venting length can be 125', plus the
first 10' of each 3", and a maximum fitting allowance of
the 3", total two 90 degree or four 45 degree before
increasing to 4". Total equivalent would be 30' of 3" plus
125' of 4". Never
use different pipe sizes for intake and
exhaust.
SPECIAL VENTING INSTRUCTIONS USING 2" VENT
PIPE
(ONLY MODELS WITH INPUTS OF 100,000 BTU AND 130,000 BTU
ARE CERTIFIED FOR 2" VENTING) HE45-100, HE45-130, HE80-130,
HE119-130
For inlet air supply, top pipe on the right of the shroud,
use 2 inch PVC schedule 40. It is very important that you
plan the location properly, to eliminate long pipe
runs and excessive fittings. Inlet pipe size must not be
reduced. Do not combine the inlet air with any other inlet
pipe, including an inlet to an additional similar appliance.
The joints must be properly cleaned, primed and cemented. The piping must also be properly supported as per
local and national standard plumbing codes. It is important that the piping be clean and free from burs, debris,
ragged ends and particles of PVC.
For exhaust piping, lower pipe on the right of the shroud,
use 2 inch PVC schedule 40 NON FOAM CORE. Use 2
inch ABS NON FOAM CORE or 2 inch CPVC schedule
40 or 80 only when required to meet local venting codes.
Exhaust piping should be sloped back to the connection
on the AdvantagePlus, at least 1/4 inch per foot of pipe,
to remove the condensate that forms within the pipe. The
total combined length of pipe, (inlet air piping plus
exhaust piping) including allowances for elbows, should
not exceed 85 equivalent feet. The total combined length
of pipe, including allowances for elbows, should not be
less than 22 equivalent feet (minimum length of 12 feet of
piping, including allowances for elbows, on the inlet and
the exhaust). Choose your vent termination locations
carefully. You must make certain that exhaust gas does
not re-circulate back into the air inlet pipe. You must
place your vent terminations in an open area, according
to the venting guidelines section on page 8.
PIPE / FITTINGS WHEN USING 2" VENT PIPE
All inlet air and exhaust venting may use standard PVC
schedule 40 piping, conforming to ASTM D-1785, and fittings conforming to ASTM D-2466, or ABS pipe conforming to ASTM D-3965 and ASTM D-2661, and fittings conforming to ASTM D-3311 and ASTM D-2661. (NEVER
use cellular foam core pipe on exhaust piping)
FOR LONGER VENT LENGTHS WHEN USING
2" VENT PIPE
You may use 3 inch venting on both the intake and
exhaust to lower the pressure drop and provide additional vent length. It is imperative when using 3 inch venting
to follow these instructions carefully. For longer vent
lengths, the first 10 feet of both the intake and exhaust
piping must be 2 inches. For the first 10 foot use 2 inch
PVC schedule 40 NON FOAM CORE, 2 inch ABS NON
FOAM CORE or 2 inch CPVC schedule 40 or 80 plus one
90 degree or two 45 degree elbows. Then use a 2" x 3"
reducing coupling of like material. Then proceed with 3
inch PVC schedule 40 NON FOAM CORE, 3 inch ABS
NON FOAM CORE or 3 inch CPVC schedule 40 or 80
pipe and fittings for both the intake and exhaust piping.
On 3 inch pipe you may go an additional 125 equivalent
feet of pipe and fittings, combined total length. The total
combined equivalent vent length would be 30 equivalent
feet of 2-inch vent and 125 equivalent feet of 3-inch vent,
for a maximum equivalent vent length of 155 feet. Never
use different pipe sizes for intake and exhaust.
CLEANER / CEMENT
Cement for all venting must be ALL PURPOSE Cement,
and must conform to ASTM D-2235, D-2564 and F-493,
and cleaner for the piping and fittings must conform to
ASTM F-656.

VERY IMPORTANT SET-UP INSTRUCTIONS!
IF YOU HAVE A COMBUSTION ANALYZER, THE FOLLOWING RATINGS WILL BE VERY HELPFUL IN SETTING UP YOUR ADVANTAGE PLUS:
The fully integrated water heater control is an all electronic, fully automatic controller which will provide many
years of trouble free service. The control requires no
periodic maintenance and includes a built-in microprocessor which performs a number of diagnostic tests to
verify proper appliance and control operation. Should an
unsafe condition occur, the burner will shut down and the
appropriate status indicators will illuminate indicating the
need for service. Consisting of two printed circuit board
assemblies, the controller's main board is attached to the
inside left of the shroud while the display board is mounted to the front top of the shroud. This arrangement simplifies access for the user adjustments while enhancing
the visibility of the temperature display and status indicators. A power step-down transformer and blower pressure switch are also mounted on the inside left of the
shroud. The controller display functions include a high
visibility three digit LED readout which is used to display
the actual water temperature within the tank along with
the programmed desired water temperature (set point
temperature). Nine individual LED indicators are also
mounted on the display board which are used to determine the operating status of the appliance and provide
assistance when troubleshooting any problems which
may occur. All indicators are of the solid state variety and
should last for the life of the appliance. The controller
has sufficient built-in memory to retain the programmed
temperature set point in the event power is ever interrupted.The final component of the control system
includes a temperature sensing probe which is threaded
into the side of the tank. This probe is of unique construction in that both the temperature sensing/control and
safety limit functions are performed by this single device.
All probe components are of solid state construction to
provide extended operational life.
START UP PROCEDURE
(NEVER APPLY POWER TO AN ADVANTAGEPLUS
UNIT THAT IS NOT COMPLETELY FILLED WITH
WATER)
1. Make sure that the AdvantagePlus has been installed
to these instruction procedures along with all applicable
state and local codes.
2. Make sure all gas piping and connections have been
verified and inspected by all applicable inspectors. Turn
on gas supply. Ensure that the gas line and the LP tank,
if applicable, has been properly purged. Failure to properly purge the gas lines will result in failure to
operate.
3. Make sure that the cold water supply has been turned
on and the AdvantagePlus is completely filled with water.
Verify by opening a hot water faucet, or purging at the
dishwasher, and allowing water to flow until all air is
removed and a clear water flow is present.

TEMPERATURE SET POINT ADJUSTMENT
PROCEDURE
WARNING
!
When this water heater is supplying general purpose
hot water requirements for individuals, a thermostatically controlled mixing valve for reducing point of
use water temperature is recommended. Contact a
licensed plumber or the local plumbing authority for
further instructions.
The three digit LED display will illustrate actual water
temperature within the tank under normal operating conditions. However, this display is also used to indicate the
temperature set point when in the programming mode.
The controller has a temperature set point range of 70°F
to 160°F (Booster models have a maximum set point of
180°F), with a factory setting of 120°F.
NOTE: Power must be applied to the controller prior
to any programming operations.
To change or access the programmed temperature set
point value, utilize the red button on the display panel.
Momentarily depressing the button will briefly illustrate
the existing set point value. If the button is held down for
more than one second, the programming mode is
entered and the set point value will begin incrementing by
one degree per second. When the desired set point
value is reached, simply release the button and the controller will automatically retain this value in temporary
memory. After 30 seconds, this new set point will be
retained in permanent memory
NOTE: If power is interrupted during this 30 second
period, the new set point will not be retained in permanent memory. It is a good practice to re-check the
set point value approximately 60 seconds after a new
value has been entered.
If the button is held down, the maximum set point will
reach 160°F (180°F on Booster models) and stop. This is
the maximum value. At this point, if the desired set point
has not been obtained, release the button and depress it
again, the set point will decrement down to 70
stop. The set point value will now restart at 70
once again increase in value for as long as the button is
pressed.
11
DANGER
CAUTION
!
!
There is a hot water SCALD POTENTIAL if the
thermostat is set too high.
THERMOSTAT DIFFERENTIAL ADJUSTMENT
PROCEDURE
8. If flame is present, the control will enter the heating
mode where it will continue heating the tank water until
the set point temperature plus 4°F is reached. At this
point, the gas valve is closed and the control enters the
post-purge cycle. The flame can be viewed through a
window on the lower right of combustion blower flange.
To allow proper water heater operation, the control has
an 8°F "window" around the set point. This means that
the burner will be turned on when the water temperature
drops to 4°F below the set point, and it will be turned off
when the water temperature reaches 4°F above the set
point. Thus, if the set point is set to 120°F., the control
will turn on the burner when the water temperature drops
to 116°F., and will continue to heat the water until the
temperature reaches 124°F. The differential is factory set
to 8°F (+ or- 4°F.) If another differential is required, the
value of the differential can be field adjusted by holding
the set point button when power is applied to the control.
Shut off power to the control. Next hold in the set point
button. Now reapply power to the control. Using the set
point button, the value of the differential can be incremented or decremented as above. When the proper
value is reached, release the button and wait for the display to show "00". This indicates the new differential has
been stored into permanent memory. Remove power
and restart control by applying power for normal operation.
OVERALL APPLIANCE AND CONTROL OPERATION
9. The post purge cycle continues to run the combustion
blower for an additional 30 seconds to purge the system
of all combustion gases. After this time period, the blower is de-energized and will coast to a stop.
10. The control will now enter the idle state while continuing to monitor internal tank water temperature. If the
temperature drops to 4°F below the set point value, the
control will automatically return to step 1.
STATUS INDICATORS
Pages 16-20 contain nine individual diagrams which illustrate the various operating states of the appliance and
their relation to the LED status indicators found on the
controller. These diagrams reflect normal water heater
operation.
MAINTENANCE
In unusually dirty or dusty conditions, care must
be taken to keep appliance door in place. Failure
to do so VOIDS WARRANTY!
A normal operating sequence is as follows:
1. The control determines that the actual water temperature inside the tank is 4 degrees F below the programmed temperature set point.
2. The control performs selected system diagnostic
checks.
3. If all checks are successfully passed, the combustion
blower is energized for the 40 second pre-purge cycle.
4. After the pre-purge cycle is complete, power is applied
to the ignitor element for the ignitor warm-up period
(blower should continue to run).
5. The ignitor warm-up period will last for 30 seconds,
then gas valve will be opened, allowing gas to enter the
burner chamber.
6. The ignitor will remain on for an additional 4 seconds,
then it will be turned off.
7. After an additional 2 seconds, the control will verify the
presence of flame. If the flame was not established, the
gas valve will be closed, power will be removed from the
ignitor element, and the control will run the blower for 30
seconds. This removes excess fuel from the combustion
chamber. At this point, the control will return to step 2.
The control system requires no periodic maintenance
under normal conditions. However, in unusually dirty or
dusty conditions, periodic vacuuming of the cover to
maintain visibility of the display and indicators is recommended.
INTERNAL WIRING
For specific wiring information, please refer to the diagrams on pages 21 and 22.
SHUTDOWN PROCEDURE
If the burner is operating, lower the set point value to
70°F and wait for the burner to shut off. Continue to wait
for the combustion blower to stop so all latent
combustion gases are purged from the system.
This should take a maximum of 40 to 90 seconds.
Disconnect the electrical supply. If the burner is not operating, disconnect the electrical supply.
VACATION PROCEDURE
If there is danger of freezing, change the set point to
70°F. DO NOT
danger of freezing, follow the "Shutdown Procedure".

turn off electrical power. If there is no
FAILURE TO OPERATE
CORROSIVE ATMOSPHERES
Should the burner fail to light, the control will perform two
more ignition trials prior to entering a lockout state (flashing “LOC”). Note that each subsequent ignition trial will
not occur immediately. After a failed ignition trial, the
blower must run for approximately 10 seconds to purge
the system, then the ignitor element must complete a 30
second warm-up period. Therefore, a time period of
approximately 40 to 90 seconds will expire between each
ignition trial. If the burner lights during any one of these
three ignition trials, normal operation will resume. If the
burner lights, but goes off in about 4 seconds, check the
polarity of the wiring. See electrical on page 6. If the
burner does not light after the third ignition trial, the
control will enter a lockout state. This lockout state
indicates that a problem exists with either the appliance, the controls, or the gas supply. Under such cir-
cumstances, a qualified service technician should be
contacted immediately to properly service the appliance
and correct the problem. If a technician is not available,
depressing the red button once will remove the lockout
state so additional trials for ignition can be performed.
Any time flashing double zero’s are shown, you must
look for an LED out, or flashing. The LED that is out
or flashing will assist you in diagnosing lock out condition.
FUEL CONVERSIONS
This product may be converted from L.P. gas (propane)
to Natural gas or from Natural gas to L.P. gas (propane).
For information and requirements about this procedure
call the Technical Service Department at 1-800-432-
8373.
WARNING
!
Should overheating occur or the gas supply fail to shut
off, turn off the manual gas control valve to the appliance.
The heater should not be installed near an air supply containing halogenated hydrocarbons. For example, the air
in beauty salons, dry cleaning establishments, photo processing labs, and storage areas for liquid and powdered
bleaches or swimming pool chemicals often contain
hydrocarbons. The air there may be safe to breathe, but
when it passes through a gas flame, corrosive elements
are released that will shorten the life of any gas burning
appliance. Propellants from common spray cans or gas
leaks from refrigeration equipment are highly corrosive
after passing through a flame. The limited warranty is
voided when failure of water heater is due to a corrosive
atmosphere. (Reference is made to the limited warranty
for complete terms and conditions.)
CONDENSATE
This is a condensing high efficiency appliance, therefore
this unit has a condensate removal system. Condensate
is nothing more than water vapor, derived from the combustion products, similar to an automobile when it is initially started. This condensate does have a low pH and
should be treated with a condensate filter. This filter contains either lime crystals or marble crystals, which will
neutralize the condensate. The outlet of the filter is sized
for 5/8" ID (inside diameter) plastic tubing. It is very
important that the condensate line is sloped away from
and down to a suitable inside drain. If the condensate
outlet on the AdvantagePlus is lower than the drain, you
must use a condensate removal pump. It is also very
important that the condensate line is not exposed to
freezing temperatures, or any other type of blockage.
Plastic tubing should be the only material used for the
condensate line. Steel, brass, copper, or other metals will
be subject to corrosion and deterioration. A second vent
may be necessary to prevent condensate line vacuum
lock if a long horizontal run is used. Also an increase to
1" tubing may be necessary.
WARNING
!
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 the water heater if
the control system or any gas control which has been
under water.

IF THERE WAS NO IGNITION:
1. Make sure the gas valve is in the "on" position, gas is
on to the unit, and the gas valve wiring harness is
plugged into the gas valve and into the control board.
2. Turn the adjustment screw under the brass cap. Turn
one full turn clockwise with a small flathead screwdriver.
Turning the adjustment screw clockwise increases the
amount of gas.
3. If the unit still does not ignite, turn the adjustment
screw two full turns counterclockwise.
IF IGNITION WAS POOR:
1. Look at the color of the flame through the sight glass
while the unit is running. If it is green or red in color, or
the heater whistles on ignition, turn the adjustment screw
counterclockwise at 1/8” turn intervals until the flame
turns blue/light blue in color or the whistling at ignition
stops. If the flame is very weak or pulsing, turn the
adjustment screw clockwise until the flame steadies.
2. Put the gas valve adjustment screw cover back in

ALL TROUBLESHOOTING TO QUALIFIED SERVICE
PERSONNEL.
TROUBLESHOOTING
The appliance controller has many inherent diagnostic
and fault detection routines built into its operating software and hardware. These routines, along with the three
digit LED display and nine LED status indicators present
on the display panel, can greatly assist the service person in quickly pinpointing the source of problems that
may occur with the appliance. In certain circumstances,
multiple LED's may be lit or flashing to better pinpoint the
problem. The following charts, diagrams, and information can be used during troubleshooting procedures. See
also Trouble Shooting Guides and Sequence of
Operations at the end of this Use and Care Manual.
3. Put the AdvantagePlus cabinet door back into place.
If an error message is still indicated after removal of the replaceable 3 amp fuse on the CONTROL,
there is a problem with the transformer. The TRANSFORMER has an internal non-replaceable fuse.
The transformer must be replaced. Please contact your local distributor or service professional.
