These units include The Hydrocannon (Self-Cleaning System) installed  
in the front water inlet, see Figure 2. The Hydrocannon inlet tube can Blower/Burner assemBly  
only be used in the front water inlet connection. Do not install the  
Hydrocannon inlet tube in either the top or back inlet water connection.  
The Hydrocannon must be oriented correctly for proper function. There  
is a marked range on the pipe nipple portion of the Hydrocannon, 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.Apipe union is  
supplied with the Hydrocannon to reduce the probability of misaligning  
the Hydrocannon accidentally while tightening the connection to the  
inlet water supply line. Improper orientation of the Hydrocannon can  
cause poor performance of the heater and can significantly reduce  
outlet water temperatures during heavy draws.  
note: the hydrocannon may have 1, 3 or 7 cross tubes.

high limit switCh  
spark igniter  
The digital thermostat (Figure 3) contains the high limit (energy  
cutout) switch. The high limit switch interrupts burner gas flow should  
the water temperature reach 203°F (95°C).  
The ignition control energizes the Spark Igniter to ignite the burner.  
intake air screen  
The intake air screen is attached to the inlet end of the combustion  
blower. Inspect the intake air screen every six months. The intake air  
screen should be cleaned of any buildup of debris or foreign material.  
In the event of high limit switch operation, the water heater 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.  
flame sensor  
The control system monitors the flame sensor to confirm that flame is  
present at the burner. If a flame is not verified during the ignition trial  
period (4 seconds) the control system will immediately de-energize  
the 24 VAC Gas Valve as indicated on the Sequence of Operation  
Flow Chart (Figure 24).  
Continued manual resetting of high limit control, preceded by higher than  
usual water temperature is evidence of high limit switch operation.  
Contact your dealer or service agent if continued high limit switch  
operation occurs.

insulation Blanket  
Breathing Hazard - Carbon Monoxide Gas  
Do not obstruct water heater air intake  
with insulating blanket.  
Gas and carbon monoxide detectors  
are available.  
Install water heater in accordance with  
the instruction manual.  
Breathing carbon monoxide can cause brain damage or  
death. Always read and understand instruction manual.  
Insulation blankets are available to the general public for external  
use on gas water heaters but are not necessary with these  
products. The purpose of an insulation blanket is to reduce the  
standby heat loss encountered with storage tank heaters. The  
water heaters covered by this manual meet or exceed the energy  
Policy Act standards with respect to insulation and standby heat  
loss requirements, making an insulation blanket unnecessary.  
Should you choose to apply an insulation blanket to this  
heater, you should follow these instructions. See the Features  
and Components section of this manual for identification of  
components mentioned below. Failure to follow these instructions  
can restrict the air flow required for proper combustion, potentially  
resulting in fire, asphyxiation, serious personal injury or death.  
figure 7.  
do not apply insulation to the front of the combustion  
chamber flange plate to insure that the spark igniter, flame  
sensor, and sightglass remain uncovered.  
nsf leg kit  
do not cover the gas valve or the Temperature-Pressure  
relief Valve.  
do not apply insulation within 5” (13 cm) of the blower, to  
insure the safe operation of the blower assembly.  
do not apply insulation on the control box that encloses  
the thermostat, ignition control, and variable frequency drive.  
do not cover the instruction manual. Keep it on the side of  
the water heater or nearby for future reference.  
do obtain new warning and instruction labels from the  
manufacturer for placement on the blanket directly over the  
existing labels.  
do inspect the insulation blanket frequently to make certain  
it does not sag, thereby obstructing combustion air flow.  
hard water  
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

installation reQuirements  
4. When installing multiple water heaters in the same gas  
gas supply systems  
supply system it is recommended that individual positive  
lock-up gas pressure regulators be installed at each unit.  
low pressure building gas supply systems are defined as those  
systems that cannot under any circumstances exceed 14” W.C.  
(3.49 kPa) (1/2 PSI Gauge). These systems do not require  
pressure regulation. Measurements should be taken to insure  
that gas pressures are stable and fall within the requirements  
stated on the water heater rating plate. readings should be  
taken with all gas burning equipment off (static pressure) and  
with all gas burning equipment running at maximum rate (dynamic  
pressure). The gas supply pressure must be stable within 1.5”  
W.C. (0.37 kPa) from static to dynamic pressure to provide good  
performance. Pressure drops that exceed 1.5” W.C. (0.37 kPa)  
may cause rough starting, noisy combustion or nuisance outages.  
Increases or spikes in static pressure during off cycles may  
cause failure to ignite or in severe cases damage to appliance  
gas valves. If your low pressure system does NOT meet these  
requirements, the installer is responsible for the corrections.  
power supply  
The water heaters covered in this manual require a 120 VAC,  
1Ø (single phase), 60Hz, 15 amp power supply and must also  
be electrically grounded in accordance with local codes or, in the  
absence of local codes, with the National electrical Code, ANSI/  
NFPA 70 or the Canadian electrical Code, CSA C22.1.  
water temperature Control and mixing ValVes  
Water temperature over 125°F (52°C)  
can cause severe burns instantly  
resulting in severe injury or death.  
Children, the elderly and the  
physically or mentally disabled are at  
highest risk for scald injury.  
High Pressure building supply systems use pressures that exceed  
14” W.C. (3.49 kPa) (1/2 PSI Gauge). These systems must use  
field supplied regulators to lower the gas pressure to less than  
14” W.C. (3.49 kPa) (1/2 PSI Gauge). Appliances require gas  
regulators that are properly sized for the water heater input and  
deliver the rating plate specified pressures. Gas supply systems  
where pressure exceeds 5 PSI (34.5 kPa) often require multiple  
regulators to achieve desired pressures. Systems in excess  
of 5 PSI building pressure should be designed by gas delivery  
professionals for best performance. Water heaters connected to  
gas supply systems that exceed 14” W.C. (3.49 kPa) (1/2 PSI  
Gauge) at any time must be equipped with a gas supply regulator.  
Feel water before bathing or  
showering.  
Temperature limiting devices such as  
mixing valves must be installed  
when required by codes and to  
ensure safe temperatures at fixtures.  
Water heated to a temperature which will satisfy clothes washing,  
dish washing, and other sanitizing needs can scald and cause  
permanent injury upon contact. Short repeated heating cycles  
caused by small hot water uses can cause temperatures at the  
point of use to exceed the water heater’s temperature setting by  
up to 20°F (11°C).  
gas pressure reQuirements  
All models require a minimum gas supply pressure of 3.5” W.C.  
(0.87 kPa) The minimum supply pressure is measured while gas  
is flowing (dynamic pressure). The supply pressure (dynamic)  
should never fall below 3.5” W.C. (0.87 kPa) The supply pressure  
should be measured with all gas fired appliances connected to  
the common main firing at full capacity. If the supply pressure  
drops more than 1.5” W.C. (0.37 kPa) as gas begins to flow to  
the water heater then the supply gas system including the gas  
line and/or the gas regulator may be restricted or undersized.  
See Supply Gas regulator section and Gas Piping section of  
this manual.  
Some people are more likely to be permanently injured by  
hot water than others. These include the elderly, children, the  
infirm and the physically/mentally disabled. Table 5 shows the  
approximate time-to-burn relationship for normal adult skin.  
If anyone using hot water provided by the water heater being  
installed fits into one of these groups or if there is a local code  
or state law requiring a certain water temperature at the point of  
use, then special precautions must be taken.  
The gas valve on all models has a maximum gas supply pressure  
limit of 14" W.C. (3.48 kPa). The maximum supply pressure is  
measured while gas is not flowing (static pressure).  
In addition to using the lowest possible temperature setting that  
satisfies the demand of the application a Mixing Valve should be  
installed at the water heater (see Figure 10) or at the hot water  
taps to further reduce system water temperature.  
supply gas regulator  
Mixing valves are available at plumbing supply stores. Consult  
a qualified Installer or Service Agency. Follow mixing valve  
manufacturer’s instructions for installation of the valves.  
The maximum allowable gas supply pressure for this water  
heater is 14 inches W.C. (3.48 kPa). Install a positive lock-up gas  
pressure regulator in the gas supply line if inlet gas pressure can  
exceed 14 inches W.C. (3.48 kPa) at any time. regulators must  
be sized/used according to manufacturer's specifications.

dishwashing maChines  
All dishwashing machines meeting the National Sanitation  
Foundation requirements are designed to operate with water  
flow pressures between 15 and 25 pounds per square inch  
(103 kPa and 173 kPa). Flow pressures above 25 pounds  
per square inch (173 kPa), or below 15 pounds per square  
inch (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 the 180°F (82°C)  
line to the dishwashing machine and should be adjusted to  
deliver water pressure between these limits.  
Can cause serious injury or death.  
This water heater is provided with a properly rated/sized and  
certified combination Temperature-Pressure relief Valve (T&P  
valve) by the manufacturer. The valve is certified by a nationally  
recognized testing laboratory that maintains periodic inspection  
of production of listed equipment of materials as meeting the  
requirements for relief Valves for Hot Water Supply Systems,  
ANSI Z21.22 • CSA 4.4, and the code requirements of ASMe.  
The National Sanitation Foundation also recommends circulation  
of 180°F (82°C) water. The circulation should be just enough  
to provide 180°F (82°C) water at the point of take-off to the  
dishwashing machine.  
If replaced, the new T&P valve must meet the requirements  
of local codes, but not less than a combination Temperature-  
Pressure relief Valve rated/sized and certified as indicated in  
the above paragraph. The new valve must be marked with a  
maximum set pressure not to exceed the marked hydrostatic  
working pressure of the water heater (150 psi = 1,035 kPa) and  
a discharge capacity not less than the water heater btu/hr or kW  
input rate as shown on the water heater’s model rating label.  
Adjust flow by throttling a full port ball valve installed in the  
circulating line on the outlet side of the pump. Never throttle flow  
on the suction side of a pump. See Water Piping Diagrams in  
this manual.  
Closed water systems  
NOTe: In addition to the factory installed Temperature-Pressure  
relief Valve on the water heater, each remote storage tank that  
may be installed and piped to a water heating appliance must also  
have its own properly sized, rated and approved Temperature-  
Pressure relief Valve installed. Call the toll free technical  
support phone number listed on the back cover of this manual  
for technical assistance in sizing a Temperature-Pressure relief  
Valve for remote storage tanks.  
Water supply systems may, because of code requirements  
or such conditions as high line pressure, among others, have  
installed devices such as pressure reducing valves, check  
valves, and back flow preventers. Devices such as these cause  
the water system to be a closed system.  
thermal expansion  
As water is heated, it expands (thermal expansion). In a closed  
system the volume of water will grow when it is heated. 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. This condition is not covered under the limited  
warranty. The Temperature-Pressure relief Valve is not intended  
for the constant relief of thermal expansion.  
For safe operation of the water heater, the Temperature-Pressure  
relief Valve must not be removed from its designated opening  
nor plugged. The Temperature-Pressure relief Valve must be  
installed directly into the fitting of the water heater designed for the  
relief valve. Install discharge piping so that any discharge will exit  
the pipe within 6 inches (15.2 cm) above an adequate floor drain,  
or external to the building. In cold climates it is recommended  
that it be terminated at an adequate drain inside the building. be  
certain that no contact is made with any live electrical part. The  
discharge opening must not be blocked or reduced in size under  
any circumstances. excessive length, over 30 feet (9.14 m), or  
A properly sized thermal expansion tank must be installed on use of more than four elbows can cause restriction and reduce

Corrosion of the flue ways and vent system may occur if air for  
combustion contains certain chemical vapors. Such corrosion  
may result in failure and risk of asphyxiation.  
The Temperature-Pressure relief Valve must be manually  
operated at least twice a year. Caution should be taken to  
ensure that (1) no one is in front of or around the outlet of the  
Temperature-Pressure relief Valve discharge line, and (2) the  
water manually discharged will not cause any bodily injury or  
property damage because the water may be extremely hot. If  
after manually operating the valve, it fails to completely reset  
and continues to release water, immediately close the cold water  
inlet to the water heater, follow the draining instructions in this  
manual, and replace the Temperature-Pressure relief Valve with  
a properly rated/sized new one.  
Combustion air that is contaminated can greatly diminish the life  
span of the water heater and water heater components such as  
hot surface igniters and burners. Propellants of aerosol sprays,  
beauty shop supplies, water softener chemicals and chemicals  
used in dry cleaning processes that are present in the combustion,  
ventilation or ambient air can cause such damage.  
Do not store products of this sort near the water heater. Air which  
is brought in contact with the water heater should not contain any  
of these chemicals. If necessary, uncontaminated air should be  
obtained from remote or outdoor sources. The limited warranty  
is voided when failure of water heater is due to a corrosive  
atmosphere. (See limited warranty for complete terms and  
conditions).  
note: The purpose of a Temperature-Pressure relief Valve is  
to prevent excessive temperatures and pressures in the storage  
tank. The T&P valve is not intended for the constant relief of

air reQuirements  
unusually tight Construction  
In unconfined spaces in buildings, infiltration may be adequate  
to provide air for combustion, ventilation and dilution of flue  
gases. However, in buildings of unusually tight construction (for  
example, weather stripping, heavily insulated, caulked, vapor  
barrier, etc.) additional air must be provided using the methods  
described in the Confined Space section that follows.  
Breathing Hazard - Carbon Monoxide Gas  
Install water heater in accordance with  
the Instruction Manual and NFPA 54 or  
CAN/CSA-B149.1.  
To avoid injury, combustion and ventilation  
air must be taken from outdoors.  
Confined spaCe  
A Confined Space is one whose volume IS leSS THAN 50 cubic  
feet per 1,000 btu/hr (4.8 cubic meters per kW) of the total input  
rating of all appliances installed in the space.  
Do not place chemical vapor emitting  
products near water heater.  
Breathing carbon monoxide can cause brain damage or  
death. Always read and understand instruction manual.  
Openings must be installed to provide fresh air for combustion,  
ventilation and dilution in confined spaces. The required size for  
the openings is dependent on the method used to provide fresh  
air to the confined space AND the total btu/hr input rating of all  
appliances installed in the space.  
For safe operation an adequate supply of fresh uncontaminated  
air for combustion and ventilation must be provided.  
An insufficient supply of air can cause recirculation of combustion  
products resulting in contamination that may be hazardous to  
life. Such a condition often will result in a yellow, luminous burner  
flame, causing sooting of the combustion chamber, burners and  
flue tubes and creates a risk of asphyxiation.  
exhaust fans  
Where exhaust fans are installed, additional air shall be provided  
to replace the exhausted air. When an exhaust fan is installed  
in the same space with a water heater, sufficient openings to  
provide fresh air must be provided that accommodate the  
requirements for all appliances in the room and the exhaust fan.  
undersized openings will cause air to be drawn into the room  
through the water heater’s vent system causing poor combustion.  
Sooting, serious damage to the water heater and the risk of fire  
or explosion may result. It can also create a risk of asphyxiation.  
Do not install the water heater in a confined space unless an  
adequate supply of air for combustion and ventilation is brought  
in to that space using the methods described in the Confined  
Space section that follows.  
Never obstruct the flow of ventilation air. If you have any doubts  
or questions at all, call your gas supplier. Failure to provide the  
proper amount of combustion air can result in a fire or explosion  
and cause property damage, serious bodily injury or death.  
louvers and grilles  
The free areas of the fresh air openings in the instructions that  
follow do not take in to account the presence of louvers, grilles or  
screens in the openings.  
unConfined spaCe  
An unconfined Space is one whose volume IS NOT leSS THAN  
50 cubic feet per 1,000 btu/hr (4.8 cubic meters per kW) of the  
total input rating of all appliances installed in the space. rooms  
communicating directly with the space, in which the appliances  
are installed, through openings not furnished with doors, are  
considered a part of the unconfined space.  
The required size of openings for combustion, ventilation and  
dilution air shall be based on the “net free area” of each opening.  
Where the free area through a design of louver or grille or screen  
is known, it shall be used in calculating the size of opening  
required to provide the free area specified. Where the louver and  
grille design and free area are not known, it shall be assumed  
that wood louvers will have 25% free area and metal louvers and  
grilles will have 75% free area. Non motorized louvers and grilles  
shall be fixed in the open position.  
Makeup air requirements for the operation of exhaust fans,  
kitchen ventilation systems, clothes dryers and fireplaces shall  
also be considered in determining the adequacy of a space to

water piping diagrams  
This manual provides detailed water piping diagrams for typical  
methods of application for the water heaters, see Water Piping  
Diagrams beginning on page 34.  
t&p Valve discharge pipe requirements:  
• Shall not be smaller in size than the outlet pipe size of the  
valve, or have any reducing couplings or other restrictions.  
The water heater may be installed by itself, or with a separate  
storage tank. When used with a separate storage tank, the  
circulation may be either by gravity or by means of circulating  
pump. Adjust flow by throttling a full port ball valve installed in the  
circulating line on the outlet side of the pump. Never throttle flow  
on the suction side of a pump. See the Water Piping Diagrams  
beginning on page 34.  
• Shall not be plugged or blocked.  
• Shall not be exposed to freezing temperatures.  
• Shall be of material listed for hot water distribution.  
• Shall be installed so as to allow complete drainage of both  
the Temperature-Pressure relief Valve and the discharge  
pipe.  
note: In addition to the factory installed Temperature-Pressure  
relief Valve (T&P valve) on the water heater, each remote  
storage tank that may be installed and piped to a water heating  
appliance must also have its own properly sized, rated and  
approved Temperature-Pressure relief Valve installed.  
• Must terminate a maximum of six inches above a floor  
drain or external to the building. In cold climates, it is  
recommended that the discharge pipe be terminated at an  
adequate drain inside the building.  
Call the toll free technical support phone number listed on the  
back cover of this manual for further assistance in sizing a T&P  
valve for remote storage tanks.  
• Shall not have any valve or other obstruction between the  
relief valve and the drain.

supply gas regulator  
The minimum gas supply pressure must not be less than 3.5" w.c.  
(0.87 kPa).  
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.  
Do not subject the gas valve to inlet gas pressures of more than  
14.0” W.C. (3.48 kPa). A supply gas regulator is necessary if higher  
gas pressures are encountered. See Gas Pressure requirements  
and Supply Gas regulator sections on page 12.  
Size the main gas line in accordance with Table 8. The figures shown  
are for straight lengths of pipe at 0.5 in. W.C. pressure drop, which is  
considered normal for low pressure systems. Note: Fittings such as  
elbows, tees and line regulators will add to the pipe pressure drop.  
Also refer to the latest version of the National Fuel Gas Code.  
1. Supply gas regulators must be rated above the input btu/hr rating  
of the water heater they supply.  
2. Supply gas regulators shall have inlet and outlet connections not  
less than the minimum supply gas line size for the water heater  
they supply. See Table 8. on page 23.  
Schedule 40 Steel or Wrought Iron Pipe is the preferred material  
for the gas line of this water heater. It is imperative to follow the  
sizing recommendations in the latest version of the National Fuel  
Gas Code if Corrugated Stainless Steel Tubing (CSST) is used as  
the gas line for this water heater.

The heater is not intended for operation at higher than 14.0" W.C.-  
natural gas, (1/2 pound per square inch gage) 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.

Install sediment trap in accordance  
with NFPA 54.  
It is important to guard against gas valve fouling from contaminants  
in the gas ways. Such fouling may cause improper operation, fire or  
explosion.  
Any time work is done on the gas supply system perform a leak test  
to avoid the possibility of 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.  
1. For test pressures exceeding 1/2 psi (3.45 kPa) disconnect the  
water heater and its Main Gas Shutoff Valve from the gas supply  
piping system during testing, see Figure 21. The gas supply line  
must be capped when disconnected from the water heater.  
To trap any dirt or foreign material in the gas supply line, a sediment  
trap must be incorporated in the piping (see Figure 21). The sediment  
trap must be readily accessible and not subject to freezing conditions.  
Install in accordance with recommendations of serving gas suppliers.  
refer to the latest version of the National Fuel Gas Code.  
2. For test pressures of 1/2 psi (3.45 kpa) or less, the appliance need  
not be disconnected, but must be isolated from the supply gas line  
by closing the Main Gas Shutoff Valve during testing.  
3. Coat all supply gas line joints and connections upstream of the  
water heater with a non-corrosive soap and water solution to  
test for leaks. bubbles indicate a gas leak. Do not use matches,  
candles, flame or other sources of ignition for this purpose.  
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.  
4. repair any leaks before placing the water heater in operation.  
purging  
gas meter size natural gases only  
Gas line purging is required with new piping or systems in which air  
has entered.  
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.  
Purging should be performed per the current edition of NFPA 54 the  
National Fuel Gas Code.

other appliances connected to the venting system are not in  
operation.  
water temperature adjustment  
1. Seal any unused openings in the venting system.  
Water temperature over 125°F (52°C)  
can cause severe burns instantly  
resulting in severe injury or death.  
2. Inspect the venting system for proper size and horizontal pitch, as  
required in the National Fuel Gas Code, ANSI Z223.1or the CAN/  
CGA b149 Installation Codes and these instructions. Determine  
that there is no blockage or restriction, leakage, corrosion and  
other deficiencies which could cause an unsafe condition.  
Children, the elderly and the  
physically or mentally disabled are at  
highest risk for scald injury.  
Feel water before bathing or  
showering.  
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.  
Temperature limiting devices such as  
mixing valves must be installed  
when required by codes and to  
ensure safe temperatures at fixtures.  
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.  
4. Follow the lighting instruction. Place the water heater being  
inspected in operation. Adjust thermostat so appliance shall  
operate continuously.  
5. Inspect vent system for leakage after 5 minutes of main burner  
operation.  
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.  
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.

The following information will describe the Sequence of Operation 8. If the Flame Sensor does not detect a strong enough flame, the  
for this water heater.  
Ignition Control shuts off the Gas Valve and allows the blower to  
purge the unit for 30 seconds. At that time, the Ignition Control  
restarts with step 6. It will try and ignite the main burners 2 more  
times. If the unit does not light, the Ignition Control will wait 15  
minutes and then restart at step 6. This cycle will continue until  
the unit lights or the power is shutoff to the unit.  
1. Switch power on to unit.  
2. Thermostat calls for heat.  
3. Variable Frequency Drive sends power to blower.  
4. Combustion blower initiates air flow through water heater closing  
the Prover Switch.  
9. If the Flame Sensor detects a strong flame, the Ignition Control  
will allow the unit to operate until the thermostat is satisfied.  
5. blower runs at low speed for 30 second pre-purge.  
10. Once the unit is satisfied, the Thermostat will shut off the blower,  
Gas Valve and Ignition Control and the unit will be in standby  
mode until another call for heat is initiated by the thermostat.  
6. The Ignition Control provides power to the Spark Igniter and  
opens the Gas Valve.  
7. Ignition Control maintains spark for up to 4 seconds and monitors  
Flame Sensor to determine if burner is lit.

When checking theTemperature-Pressure relief Valve operation,  
make sure that (1) no one is in front of or around the outlet of the

To check the relief valve, lift the lever at the end of the valve  
several times, see Figure 25. The valve should seat properly and  
operate freely.  
If after manually operating the valve, it fails to completely reset and  
continues to release water, immediately close the cold water inlet  
to the water heater and drain the water heater, see Draining and  
Flushing on page 29. replace the Temperature-Pressure relief  
The anode rod is used to protect the tank from corrosion. Most  
hot water tanks are equipped with an anode rod. The submerged  
rod sacrifices itself to protect the tank. Instead of corroding tank,  
water ions attack and eat away the anode rod. This does not affect  
water’s taste or color. The rod must be maintained to keep tank  
in operating condition.  
Valve with a properly rated/sized new one, see Temperature-  
Pressure relief Valve on pages 13-14 for instructions on  
replacement.  
Anode deterioration depends on water conductivity, not necessarily  
water condition. A corroded or pitted anode rod indicates high  
water conductivity and should be checked and/or replaced more  
often than an anode rod that appears to be intact. replacement  
of a depleted anode rod can extend the life of your water heater.  
Inspection should be conducted by a qualified technician, and at  
a minimum should be checked annually after the warranty period.  
Artificially softened water is exceedingly corrosive because the  
process substitutes sodium ions for magnesium and calcium ions.  
figure 25.  
The use of a water softener may decrease the life of the water  
heater tank.  
If the Temperature-Pressure relief Valve on the water heater  
weeps or discharges periodically, this may be due to thermal  
expansion.  
The anode rod should be inspected after a maximum of three  
years and annually thereafter until the condition of the anode  
rod dictates its replacement. Anode replacement is not covered  
by warranty.  
NOTe: excessive water pressure is the most common cause of  
Temperature-Pressure relief Valve leakage. excessive water  
system pressure is most often caused by "thermal expansion"  
in a "closed system." See Closed Water Systems and Thermal

draining and flushing  
periodiC remoVal of lime deposits from  
tank type CommerCial water heaters  
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.  
Burn harzard.  
Hot water discharge.  
lime accumulation may affect the life of equipment, the efficiency  
of the heater, and fuel consumption characteristics. 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.  
Keep hands clear of drain  
valve discharge.  
It is recommended that the water heater storage tank be drained  
and flushed every 6 months to reduce sediment buildup. The  
water heater should be drained if being shut down during freezing  
temperatures.  
The time between cleaning will vary from weeks to years  
depending upon water conditions and usage.  
The depth of lime buildup should be measured periodically.  
Heaters equipped with cleanouts will have about 2" of lime  
buildup when the level of lime has reached the bottom of the  
cleanout opening. A schedule for deliming should then be set up  
based on the amount of time it would take for a 1" buildup of lime.  
It is recommended that the water heater initially be inspected  
after 6 months.  
to drain the water heater storage tank:  
1. Turn off the electrical supply to the water heater.  
2. Turn off the gas supply at the Main Gas Shutoff Valve if  
the water heater is going to be shut down for an extended  
period.  
3. ensure the cold water inlet valve is open.  
example 1:  
4. Open a nearby hot water faucet and let the water run until  
the water is no longer hot.  
Initial inspection after 6 months shows 1/2" of lime accumulation.  
Therefore, the heater should be delimed once a year.  
5. Close the cold water inlet valve to the water heater.

8. Install cleanout plate. be sure to draw plate up tight by  
tightening screws securely.  
5. remove relief valve while heater is draining. NOTe: Do not  
replace relief valve until deliming is completed. relief valve  
opening will also act as a vent in case of possible contact  
between the delimer and the anode rod(s), which may  
produce flammable hydrogen-air mixtures.  
9. replace outer jacket cover plate.  
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, uN•lIMe Professional Delimer  
should be used.  
6. If relief valve appears to be limed-up, place it in a clean glass or  
plastic container adequate in size so that you can pour enough  
uN•lIMe® into the container to cover the valve and allow  
space for foaming. When foaming stops, run fresh cool water  
into the container and rinse the relief valve for a few minutes.  
deliming using flo-jug method  
uN•lIMe in the 5 gallon size is recommended for deliming of  
all models. Contact your local dealer, distributor or water heater  
manufacturer.  
7. If heater does not drain completely after a reasonable length  
of time, turn off the main water supply valve to stop water  
from entering the tank due to a by-pass problem or defective  
cold water inlet valve. Also, check for clogged drain valve  
opening. Heater must be completely drained before  
introducing uN•lIMe.  
Prepare the Water Heater  
To delime the water heater using the Flo-Jug method, first  
prepare the heater for deliming.  
8. remove the cleanout cover and place a clean plastic bucket  
next to the cleanout opening.  
Partially open the cold water inlet valve to allow time to  
accomplish the following and then close the valve.  
Explosion Hazard  
While the water is being run through the tank, insert a stiff  
wire, copper tube flattened at one end or an opened wire coat  
hanger through the cleanout opening and scrape out any  
loose deposits of scale or sediment. This is an economical  
way to avoid unnecessary usage of the deliming solution.  
Flammable hydrogen gases  
may be present.  
Keep all ignition sources away  
from faucet when turning on  
hot water.  
repeat the opening and closing of the cold water inlet valve  
as necessary but be sure the heater is completely drained  
when ready to introduce the uN•lIMe.

“air” in hot water fauCets  
HyDrOGeN GAS: Hydrogen gas can be produced in a hot  
water system that has not been used for a long period of time  
(generally two weeks or more). Hydrogen gas is extremely  
flammable and explosive. To prevent the possibility of injury  
under these conditions, we recommend that the hot water  
faucet located farthest away from the water heater be opened  
for several minutes before any electrical appliances which  
are connected to the hot water system are used (such as a  
dishwasher or washing machine). If hydrogen gas is present,  
there will probably be an unusual sound similar to air escaping  
through the pipe as the hot water faucet is opened. There  
must be no smoking or open flame near the faucet at the time  
it is open.  
Condensation causes sizzling and popping within the burner area  
during heating and cooling periods and should be considered  
normal.  
operational Conditions  
hot water odor  
In each water heater there is installed at least one anode rod  
for corrosion protection of the tank. Certain water conditions  
will cause a reaction between this rod and the water. The most  
common complaint associated with the anode rod is one of a  
“rotten egg smell” in the hot water. The smell is a result of four  
factors which must all be present for the odor to develop:  
a. A concentration of sulfate in the supply water.  
high water temperature shut off system  
This water heater is equipped with a manual reset type high  
limit (energy Cutout) switch. The high limit switch interrupts  
the main burner gas flow should water temperature reach  
203°F (95°C).  
b. little or no dissolved oxygen in the water.  
c. A sulfate reducing bacteria which has accumulated within the  
water heater (this harmless bacteria is nontoxic to humans).  
d. An excess of active hydrogen in the tank. This is caused by  
the corrosion protective action of the anode.  
In the event of high limit switch operation, the water heater  
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 thermostat then needs to be depressed. See Figure 2  
for the location of the reset button.  
Hot water odor may be eliminated or reduced in some water  
heater models by replacing the anode(s) with one of less active  
material, and then chlorinating the water heater tank and all  
water lines.
