THE HYDROCANNON (SELF-CLEANING SYSTEM)

These units include The Hydrocannon (Self-Cleaning System) installed in the front water inlet, see Figure 2. The Hydrocannon inlet tube can 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. A pipe 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.

FIGURE 2.

HIGH LIMIT SWITCH

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).

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.

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.

BLOWER/BURNER ASSEMBLY

The fan-assisted combustion system includes a spark-to-pilot igniter, 100% premix stainless steel burners, and prejets for input rate and precision air/gas ratio control.

LOCATING THE WATER HEATER

•

•

CAUTION

Property Damage Hazard

All water heaters eventually leak.

Do not install without adequate drainage.

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.









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 igniter or main burner flames causing fire or explosion. Some local codes permit operation of gas appliances in such areas if they are installed 18" or more above the floor. This may reduce the risk if location in such an area cannot be avoided.

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 in any direction. If the heater is installed in a carpeted alcove, the entire floor shall be covered by the panel.

The heater shall be located or protected so it is not subject to physical damage by a moving vehicle.

Flammable items, pressurized containers or any other potential fire hazardous articles must 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.

The heater must not be located in an area where it will be subject to freezing.

Locate it near a floor drain. The heater should be located in an area where leakage from heater or connections will not result in damage to adjacent area or to the lower floors of the structure.

When such locations cannot be avoided, a suitable drain pan should be installed under heater. Such pans should be fabricated with sides at least 2” deep, with length and width at least 2” greater than diameter of heater and must be piped to an adequate drain.

Pan must not restrict combustion air flow.

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.

NSF LEG KIT

FIGURE 7.

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.

• 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.

• DO NOT cover the gas control 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

FIGURE 8.

The NSF Leg Kit (part number 9008883005) is needed only for applications that must conform to NSF/ANSI Standard 5. The installed height of the water heater will increase by 4" (10.2 cm) when the leg kit is installed. Follow these steps to install the Leg Kit.

Use caution to prevent damage to the unit when installing the Leg Kit

1. Lift, tilt or lay the unit on its side to access the bottom of the legs.

2. Position the extension under leg aligning the holes in the leg extension with the holes in the leg. Assemble the bolt, bevel washers, flat washers, and nut through the aligned holes in the leg and leg extension as shown in Figure 8.

3. Once in place, tighten the nut and bolt assembly. Torque to 70 ft.lbs (9.67 kgf-m).

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.

See the Maintenance Section in this manual for sediment and lime scale removal procedures.

CIRCULATION PUMPS

A circulating pump is used when a system requires a circulating loop or there is a storage tank used in conjunction with the water heater. See Water Piping Diagrams in this manual for installation location of circulating pumps.

See the Circulation Pump Wiring Diagrams (Figure 9.) in this manual for electrical hookup information. Install in accordance with the current edition of the National Electrical Code, NFPA 70 or the Canadian Electrical Code, CSA C22.1.

4. Insure that all four nut and bolt assemblies are torqued to the specified value before placing the unit on the floor.

Under no circumstances should the input exceed the rate shown on the water heater’s rating label.

Special consideration must be taken with installations above 10,100’ (3078m) for standard models.

Overfiring could result in damage to the water heater and sooting.



The water heaters covered by this manual are certified for use without modification for an altitude of 10,100 feet (3,078 m). Consult the factory for installation at altitudes over 10,100 feet (3,078 m).

Some gas utility companies derate their gas for altitude, making it unnecessary to install high altitude orifices. Call the local gas or utility company to verify BTU content.

Due to the input rate reduction at high altitudes, the output rating of the water heater is also reduced and should be compensated for in the sizing of the equipment for applications.

11

INSTALLATION REQUIREMENTS

GAS SUPPLY SYSTEMS

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.

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.

Some addition adjustment maybe required later to maintain a steady gas supply pressure.

5. When installing multiple water heaters in the same gas supply system it is recommended that individual positive lock-up gas pressure regulators be installed at each unit.

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





GAS PRESSURE REQUIREMENTS

All models require a minimum gas supply pressure as shown in

Table 3 on page 8. The minimum supply pressure is measured while gas is flowing (dynamic pressure). The supply pressure

(dynamic) should never fall below that indicated in Table 3 page

8. 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.

The gas control 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).

SUPPLY GAS REGULATOR

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.

If a positive lock-up regulator is required follow these instructions:

1. Positive lock-up gas pressure regulators must be rated at or 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 7 on page 24.

3. Positive lock-up gas pressure regulator(s) should be installed no closer than 3 feet (1 meter) and no farther than 8 feet (2.4 meters) of equivalent length from the water heater’s inlet gas connection.

4. After installing the positive lock-up gas pressure regulator(s) an initial nominal supply pressure setting of 7.0” W.C. (1.74 kPa) while the water heater is operating is recommended and will generally provide good water heater operation.

12

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).

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.

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.

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.

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.

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.

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

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.

A properly sized thermal expansion tank must be installed on all closed systems to control the harmful effects of thermal

Properly sized temperaturepressure relief valve must be installed in opening provided.

Can result in overheating and excessive tank pressure.

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.

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.

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.

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 use of more than four elbows can cause restriction and reduce the discharge capacity of the valve.

13

No valve or other obstruction is to be placed between the

Temperature-Pressure Relief Valve and the tank. Do not connect discharge piping directly to the drain unless a 6” (15.2 cm) air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in adequate quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.

CAUTION

Water Damage Hazard see Closed Water Systems and Thermal Expansion on page 13.

If you do not understand these instructions or have any questions regarding the Temperature-Pressure Relief Valve call the toll free number listed on the back cover of this manual for technical assistance.

COMBUSTIBLE MATERIAL STORAGE

•

Temperature-Pressure Relief Valve discharge pipe must terminate at adequate drain.

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.

• 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.

• 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.

• Shall not have any valve or other obstruction between the relief valve and the drain.









Keep water heater area clear and free of combustible materials, gasoline and other flammable vapors and liquids.

CONTAMINATED AIR

Burn hazard.

Hot water discharge.

Keep clear of Temperature-

Pressure Relief Valve discharge outlet.


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.

Do not place chemical vapor emitting products near water heater.


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.

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 thermal expansion. A properly sized thermal expansion tank must be installed on all closed systems to control thermal expansion,

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.

Combustion air that is contaminated can greatly diminish the life span of the water heater and water heater components such as 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).

14

AIR REQUIREMENTS


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.

Do not place chemical vapor emitting products near water heater.


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.

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.

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.

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 provide combustion, ventilation and dilution air.

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.

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.

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.

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.

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.

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.

15

FRESH AIR OPENINGS FOR CONFINED SPACES

The following instructions shall be used to calculate the size, number and placement of openings providing fresh air for combustion, ventilation and dilution in confined spaces.

VENTING INSTALLATION

VENTING

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 heater is not approved for direct vent installation.

Heater must be protected from freezing downdrafts.

Remove all soot or other obstructions from the chimney that will retard a free draft.

Type B venting is required with these heaters. For typical venting application see TECHNICAL DATA VENTING on pages 19 and 20.

This water heater must be vented in compliance with all local codes, the current revision of the National Fuel Gas Code (ANSI-Z223.1) and with the Category I Venting Tables.

If any part of the vent system is exposed to ambient temperatures below 40°F (4.4°C) it must be insulated to prevent condensation.

• Do not connect the heater to a common vent or chimney with solid fuel burning equipment. This practice is prohibited by many local building codes as is the practice of venting gas fired equipment to the duct work of ventilation systems.

• Where a separate vent connection is not available and the vent pipe from the heater must be connected to a common vent with an oil burning furnace, the vent pipe should enter the smaller common vent or chimney at a point above the large vent pipe.

WATER HEATER INSTALLATION

WATER LINE CONNECTIONS

The water piping installation must conform to these instructions and to all local code authority having jurisdiction. Good practice requires that all heavy piping be supported.

Read and observe all requirements in the following sections before installation of the water piping begins:

1. Water Temperature Control and Mixing Valves on page 12.

2. Dishwashing Machines on page 13.

3. Temperature-Pressure Relief Valve on page 13.

4. Closed Systems and Thermal Expansion on page 13.

5. For multiple water heater installations see Water Piping

Diagrams beginning on page 35.

Water (potable) Heating And Space Heating

1. All piping components connected to this unit for space heating applications shall be suitable for use with potable water.

2. Toxic chemicals, such as those used for boiler treatment, shall NEVER be introduced into this system.

3. This unit may NEVER be connected to any existing heating system or component(s) previously used with a non-potable water heating appliance.

4. When the system requires water for space heating at temperatures higher than required for domestic water purposes, a tempering valve must be installed. Please refer to Water Piping Diagrams beginning on page 35 of this manual for suggested piping arrangements.

5. These water heaters cannot be used in space heating applications only

Thermometers (not Supplied)

Thermometers should be obtained and field installed as shown in the installation diagrams.

Thermometers are installed in the system as a means of detecting the temperature of the outlet water supply.

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 35.

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 35.

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.

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.

T&P VALVE DISCHARGE PIPE







This water heater is provided with a properly rated/sized and certified combination temperature - pressure (T&P) relief valve by the manufacturer. See Temperature-Pressure Relief Valve on pages

13-14 for information on replacement and other requirements.

•

CAUTION

Water Damage Hazard

Temperature-Pressure Relief Valve discharge pipe must terminate at adequate drain.

Install a discharge pipe between the T&P valve discharge opening and a suitable floor drain. Do not connect discharge piping directly to the drain unless a 6” (15.2 cm) air gap is provided.

To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in adequate quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.

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.

• 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.

• 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.

• Shall not have any valve or other obstruction between the relief valve and the drain.

21

INSTALLATION DIAGRAMS - TOP INLET/OUTLET USAGE

Use of the top inlet water connection requires an inlet dip tube

(refer to figure 19). The tube is supplied in the heater. Follow caution labels if applying heat to this fitting. Do not allow pipe dope to contact the plastic tube during installation.

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.

Size the main gas line in accordance with Table 7. 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.

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 current edition 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 control 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 control 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.

It is important to guard against gas control 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 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 current edition of the National Fuel Gas Code.

To prevent damage, care must be taken not to apply too much torque when attaching gas supply pipe to gas control 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 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.

GAS PIPING AND SEDIMENT TRAP INSTALLATION

FIGURE 21.

GAS LINE LEAK TESTING


Use joint compound or Teflon tape compatible with propane gas.

Leak test before placing the water heater in operation.

Disconnect gas piping and main gas shutoff valve before leak testing.

Install sediment trap in accordance with NFPA 54.

Any time work is done on the gas supply system perform a leak test to avoid the possibility of fire or explosion.

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.

2. For test pressures of 1/2 psi (3.45 kpa) or less, the water heater 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.

4. Repair any leaks before placing the water heater in operation.

PURGING

Gas line purging is required with new piping or systems in which air has entered.

Purging should be performed per the current edition of NFPA 54 the

National Fuel Gas Code.

START UP

PRIOR TO START UP

Installation and start up of this water heater requires abilities and skills equivalent to that of a licensed tradesman in the field involved, see Qualifications on page 6.

Do not place the water heater in operation if any part has been under water. Immediately call a qualified service technician to inspect the water heater and to replace any part of the control system and any gas control which has been under water.

Light the water heater in accordance with the Lighting and

Operation Instruction label on the water heater and in this manual on page 27.

The water heaters covered by this manual are equipped with an electronic control system that automatically sequences the

Blower, the Igniter, the 24 VAC Gas Valve, Burner ignition, and flame sensing. The control system will lock out after three unsuccessful ignition attempts.

Before attempting start up, thoroughly study and familiarize yourself with the exact Sequence Of Operation, see the written

Sequence Of Operation on page 27 and the Sequence Of

Operation Flow Chart on page 28.

Be certain that the water heater is full of water, that air is purged from the gas and water lines and that there are no leaks in the gas and water lines. Ensure all inlet water valves are open.

Filling The Water Heater

Follow these steps to fill the water heater prior to start up.

1. Close the heater drain valve.

2. Open a nearby hot water faucet to permit the air in the system to escape.

3. Fully open the cold water inlet valve allowing the piping and water heater to fill with water.

4. Close the hot water faucet opened in Step 2 as water starts to flow.

Supply Gas Line Purging


Gas line purging is required with new piping or systems in which air has entered.

To avoid risk of fire or explosion purge discharge must not enter into confined areas or spaces where ignition can occur.

The area must be well ventilated and all sources of ignition must be deactivated or removed.



INITIAL START UP

Required Test Equipment

U-tube manometer, pressure gauge, or digital manometer.

Recommended range: 20” W.C. (5 kPa).

NOTE: All test equipment must be acclimated to ambient temperature before calibration and use.

Preparation

1. Adjust the thermostat to the lowest temperature setting.

2. Turn the water heater’s on/off switch to the “off” position.

3. Close the Main Gas Shut Off Valve, see Figure 21 on page 24.

4. Wait five (5) minutes for any residual gas to clear.

5. Open the Supply Gas Pressure Port on the gas control valve by turning the center screw counter-clockwise. Connect the manometer to the supply gas pressure test port, see Figure 22.

6. Open the Main Gas Shutoff Valve.

7. Measure and record the supply gas pressure, this is a “static” supply gas pressure reading; while the water heater is not firing.

FIGURE 22. – TOP VIEW

Lighting The Water Heater

1. Turn the water heater’s on/off switch to the “on” position.

2. Adjust the thermostat to the desired water temperature.

3. Record the supply gas pressure when the 24 VAC Gas Valve is energized and the Burner is operating. This is a “dynamic” gas pressure reading; while the water heater is firing.

4. Compare the actual supply gas pressure reading recorded above to the required minimum/maximum values given in Table

3 on page 8. Adjust supply gas pressure as necessary, see the instructions that follow.

5. After the supply gas pressure adjustments are complete, turn off the water heater and close the Main Gas Supply Shut Off Valve.

Disconnect the manometer from the Supply Gas Pressure Port and turn the center screw clockwise until the port is closed.

Supply Gas Pressure Adjustment


1. Close the Main Gas Shutoff Valve, see Figure 21 on page 24.

2. Purge all air from the supply gas line up to the water heater’s

Main Gas Shutoff Valve.

3. When all air has been purged from the supply gas line, tighten all supply gas line connections.

4. Check for gas leaks, see Gas Line Leak Testing on page 24 and repair any leaks found.

25


Do not use water heater with any gas other than the gas shown on the rating label.

Excessive gas pressure to gas valve can cause serious injury or death.

Turn off gas lines during installation.

Contact a qualified installer or service technician for installation and service.

Supply gas pressure shall be measured while the water heater is not firing (static pressure) and while the water heater is firing at full capacity (dynamic pressure).

If the supply gas pressure to the water heater is not between the required minimum and maximum values given in Table 3 on page 8 adjust the supply gas regulator as necessary. Adjust the supply gas regulator(s) per the regulator manufacturer’s instructions to achieve the required “static” and “dynamic” supply gas pressure.

Multiple Water Heater Installations:

In multiple water heater installations or in installations where the installed water heater(s) share a common gas supply main with other gas fired appliances; the supply gas pressures shall be measured at each water heater with all gas fired appliances connected to a common main firing at full capacity.

On multiple water heater installations the supply gas line regulators shall be adjusted to provide gas pressure to each water heater within the minimum and maximum supply pressure requirements listed in Table 3 on page 8 with all gas fired appliances connected to a common gas main firing at full capacity.

NOTE: A pressure drop of more than 1.5” W. C. (0.37 kPa) when the Main Burner ignites is an indication of an inadequate supply of gas and can lead to ignition failure, rough starts and/ or rough operation. If a drop of more than 1.5” W. C. (0.37 kPa) in supply gas pressure occurs when the Main Burner ignites, ensure the supply gas lines and regulator(s) are properly sized and installed. See the requirements for Supply Gas Regulator on page 12 and Gas Piping on page 24. Ensure all requirements and installation instructions are maintained.

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.

1. Seal any unused openings in the venting system.

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.

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.

4. Follow the lighting instruction. Place the water heater being inspected in operation. Adjust thermostat so water heater shall operate continuously.

5. Inspect vent system for leakage 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.

FAILURE TO CORRECT BACK DRAFTS MAY CAUSE AIR

CONTAMINATION AND UNSAFE CONDITIONS.

• 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.

CHECKING THE INPUT

Follow these instructions to determine the firing rate of the water heater.

1. Follow the procedure described in the "Initial Start Up" section on page 25 to measure the static and dynamic supply gas pressures. Verify that the static and dynamic supply gas pressures conform to the values listed in Table 3 on page 8.

2. Use this formula to “clock” the meter. Be sure that other gas consuming appliances are not operating during this interval.

(3600/T) x H = Btuh

T = Time in seconds to burn one cubic foot of gas.

H = Btu’s per cubic foot of gas.

Btuh = Actual heater input.

Example: (SBL100199)

T = 18.1 seconds

H = 1000 BTU/Cu.Ft.

Btuh = (3,600/18.1) x 1,000 = 199,000

(Compare with SBL100199 model and rating.)

UNDER NO CIRCUMSTANCES SHOULD THE GAS INPUT EXCEED

THE INPUT SHOWN ON THE HEATER'S RATING PLATE.

WATER TEMPERATURE ADJUSTMENT





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.

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.

26

SEQUENCE OF OPERATION

The following information will describe the Sequence of Operation for this water heater.

1. Switch power on to unit.

2. Thermostat calls for heat.

3. Blower power relay is energized to start the blower.

4. The blower pressure switch is closed, 24VAC power is applied to the Ignition Control Module.

5. The Ignition Control performs diagnostic self check on system components.

6. The Ignition Control begins the trial for ignition by turning on the

Spark Igniter and the Pilot Gas Valve.

7. The Ignition Control monitors the Flame Sensor during the ignition trial period.

8. If the Ignition Control does not sense the pilot flame during the ignition trial period, the Ignition Control shuts the Pilot Gas Valve and turns off the Spark Igniter. After 5 minute delay, a new trial for ignition is initiated. This sequence continues until the unit lights or “Call for Heat” is removed.

9. If the pilot flame is proved during the ignition trial period, the

Ignition Control will energize the main gas control valve to start the heating cycle. If the flame signal is lost during the heating cycle, the Ignition Control closes the gas control valve and restarts the ignition process at step 5.

10. Once the unit is satisfied, the Thermostat will turn off the 24vac power to the blower relay and the Ignition Control, and the unit will be in standby mode until another call for heat is initiated by the thermostat.

See the flow chart on page 28 for more detailed information.

MAINTENANCE

VENTING SYSTEM

Examine the venting system every six months for obstructions and/or deterioration of the vent piping. Check all vent system connections for leakage and repair or reseal as necessary.

Remove all soot or other obstructions from chimney which will retard free draft.

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.

TEMPERATURE-PRESSURE RELIEF VALVE TEST

Expansion on page 13. The Temperature-Pressure Relief Valve is not intended for the constant relief of thermal expansion.

Temperature-Pressure Relief Valve leakage due to pressure build up in a closed system that does not have a thermal expansion tank installed is not covered under the limited warranty. Thermal expansion tanks must be installed on all closed water systems.

DO NOT PLUG THE TEMPERATURE-PRESSURE RELIEF

VALVE OPENING. THIS CAN CAUSE PROPERTY DAMAGE,

SERIOUS INJURY OR DEATH.


• Burn hazard.



• Hot water discharge.

• Keep clear of Temperature-

Pressure Relief Valve discharge outlet.



It is recommended that the Temperature-Pressure Relief Valve should be checked to ensure that it is in operating condition every 6 months.

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

Temperature-Pressure Relief Valve discharge line, and (2) that the water discharge will not cause any property damage, as the water may be extremely hot. Use care when operating valve as the valve may be hot.

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 30. Replace the Temperature-

Pressure Relief Valve with a properly rated/sized new one, see Temperature-Pressure Relief Valve on pages 13-14 for instructions on replacement.

ANODE ROD INSPECTION


FIGURE 25.

If the Temperature-Pressure Relief Valve on the water heater weeps or discharges periodically, this may be due to thermal expansion.

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

29

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.

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.

The use of a water softener may decrease the life of the water heater tank.

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 rod replacement is not covered by warranty.

NOTE: Artificially softened water requires the anode rod to be inspected annually.

DRAINING AND FLUSHING

Burn harzard.

Hot water discharge.

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.

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.

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.

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.

4. Open a nearby hot water faucet and let the water run until the water is no longer hot.

5. Close the cold water inlet valve to the water heater.

6. Connect a hose to the water heater drain valve and terminate it to an adequate drain.

7. Open the water heater drain valve and allow all the water to drain from the storage tank.

8. Close the water heater drain valve when all water in the storage tank has drained.

9. Close the hot water faucet opened in Step 4.

10. If the water heater is going to be shut down for an extended period, the drain valve should be left open.

Example 1:

Initial inspection after 6 months shows 1/2" of lime accumulation.

Therefore, the heater should be delimed once a year.

Example 2:

Initial inspection after 6 months shows 2" of lime accumulation.

Therefore, the heater should be delimed every 3 months.

To Flush the Water Heater Storage Tank:

1. Turn off the electrical supply to the water heater.

2. Ensure the cold water inlet valve is open.

3. Open a nearby hot water faucet and let the water run until the water is no longer hot. Then close the hot water faucet.

4. Connect a hose to the drain valve and terminate it to an adequate drain.

5. Ensure the drain hose is secured before and during the entire flushing procedure. Flushing is performed with system water pressure applied to the water heater.

6. Open the water heater drain valve to flush the storage tank.

7. Flush the water heater storage tank to remove sediment and allow the water to flow until it runs clean.

8. Close the water heater drain valve when flushing is completed.

FIGURE 26.

9. Remove the drain hose.

DELIMING SOLVENTS

10. Fill the water heater - see Filling The Water Heater in this manual.

11. Turn on the electrical supply to place the water heater back in operation.

UN•LIME is recommended for deliming. UN•LIME is a patented food grade acid which is safe to handle and does not create the harmful fumes which are associated with other products.

12. Turn on the gas supply to the water heater at the Main Gas

Shutoff Valve.

13. Allow the water heater to complete several heating cycles to ensure it is operating properly.

30

UN•LIME may be obtained from your dealer, distributor or water heater manufacturer. Order Part Number 9005416105, 1 gallon, packed 4 gallons per case or Part Number 9005417105, 5 gallon container.

NOTE: Un•Lime is not available for use in Canada.

Hydrochloric base acids are not recommended for use on glass lined tanks.

Observe handling instructions on label of product being used.

TANK CLEANOUT PROCEDURE

The following practices will ensure longer life and enable the unit to operate at its designed efficiency:

1. Once a month the heater should be flushed. Open the drain valve and allow two gallons of water to drain from the heater.

Inlet water valve should remain open to maintain pressure in tank.

2. A cleanout opening is provided for periodic cleaning of the tank. Gas must be shut off and heater drained before opening cleanout.

To clean heater through cleanout opening, proceed as follows:

3. Drain heater.

4. Remove outer cover plate from lower side of heater jacket.

5. Remove six (6) hex head screws securing tank cleanout plate and remove plate.

6. Remove lime, scale, or sediment using care not to damage the glass lining.

7. Inspect cleanout plate gasket, if new gasket is required, replace with part no. 9004099215.

8. Install cleanout plate. Be sure to draw plate up tight by tightening screws securely.

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.

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.

Prepare the Water Heater

To delime the water heater using the Flo-Jug method, first prepare the heater for deliming.


Flammable hydrogen gases may be present.

Keep all ignition sources away from faucet when turning on hot water.

Do not smoke or have open flame or sparks in vicinity of heater.

Do not mix UN•LIME with other chemicals. Do not allow contact with magnesium, aluminum or galvanized metals.

Chemical Hazard

• Product contains phosphoric acid.

• Keep out of reach of children.

• Use rubber or neoprene gloves.

UN•LIME contains phosphoric acid. In case of external contact, flush with cool water. If irritation persists, get medical attention. If swallowed, give 1 or 2 glasses of water or milk and call physician.

Get immediate medical attention for eyes. Keep out of reach of children.

NOTE: THE USE OF RUBBER OR NEOPRENE GLOVES IS

RECOMMENDED, ESPECIALLY IF YOU HAVE ANY OPEN

SORES OR CUTS TO AVOID UNNECESSARY IRRITATION

OR DISCOMFORT.

1. Turn off fuel and/or power supply to heater. Also, turn off power to any electrical device or equipment, which is attached, or part of the system.

2. Open hot water side of faucet closest to heater and allow water to run until it is cool enough to handle safely.

3. Close cold water inlet valve to heater.

4. Connect hose to drain valve at bottom of heater and start draining heater into suitable floor drain area.

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.

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.

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.

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.

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.

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.

Upon completion, reinstall the cleanout cover and use a new cleanout cover gasket (part number 9004099215).

Remove the drain valve.

31

9. Install the long plastic male adapter insert fitting into the drain valve opening of heater after applying Teflon tape or paste to threads. Tighten firmly by hand and use wrench or adjustable pliers to check for secure connection. Do not over tighten to avoid damage to threads and fittings.

Prepare the Up-N-Down Transfer Kit

The next step is the preparation on the Up-N-Down Transfer Kit, if you have not already done so:

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

Note: If your container does not have the vent cap and vent boss, drill a 3/16” hole in the handle. When you have finished deliming you will be able to plug this drilled vent with the stainless steel screw that is supplied with the kit.

2. Remove the container’s cap and cut the plastic membrane located in the 3/4” IPT opening in the cap. Take care to not damage the threads.

3. Find the 3/4” male adapter, apply teflon tape to the threaded end and screw it into the 3/4” IPT opening in the cap.

4. Put cap with male adapter back on the container and slide

3/4” hose over end of male adapter and fasten in place using hose clamp provided.

Delime using Flo-Jug Method

5. Slide the hose clamp over end of hose and slide hose over the male adapter in the water heater drain opening and secure in place using hose clamp.

6. Lift container to the “Pour” Position, see Figure 27, being careful to keep the vent in the handle above the liquid level and pour the UN•LIME into the heater.

7. Lower container, you may have to place the container on its empty carton to prevent the UN•LIME from flowing back into the container.

8. Let UN•LIME remain in the heater for 5 minutes and then lower the container to the “Drain” Position, see Figure 27.

9. Deliming activity is indicated by foaming on the surface of the

UN•LIME. If there is deliming activity, repeat steps 6 thru 8.

Normally, lime removal will be completed within one hour. Severe build-up of lime may take longer than an hour to complete descaling.

Note: To check UN•LIME for continued use, place some scale or white chalk in a glass with a small amount of UN•LIME. If the material is vigorously dissolved by the UN•LIME, it can be reused; if not, the UN•LIME should be replaced.

FIGURE 27.

SERVICE

The installer may be able to observe and correct certain problems which may arise when the unit is put into operation. HOWEVER, it is recommended that only a qualified service agency, using appropriate test equipment, be allowed to service the heater.

As preliminary step, check wiring against diagram, check for grounded, broken or loose wires. Check all wire ends to be sure that they are making good contact.

IGNITION CONTROL SYSTEM

Before calling your qualified service agency, the following checklist should be examined to eliminate obvious problems from those requiring replacement or servicing.

• Check that “main gas shutoff valve” is fully open and that gas service has not been interrupted.

• Check electrical supply to the water heater for possible blown

(or tripped) fusing or power interruption. Also check the 3 amp fuse on the front of the digital thermostat (Fig. 2).

• Is the water temperature in tank below the thermostat dial setting on the water heater thermostat (calling for heat)?

• It is possible that the high limit (E.C.O.) has functioned to shut off the water heater. See page 7 - High Limit Switch for reset procedure. Contact your service agent if limit continues to function to shut off water heater.

SYSTEM DIAGNOSTICS

Your water heater is equipped with an ignition control that incorporates a diagnostic system to assist in troubleshooting the water heater. The green LED codes on the ignition module are as follows:

TABLE 9.

2 FLASHES 5 Minutes Retry Delay

3 FLASHES Recycle - flame failed during run

4 FLASHES Flame sensed out of sequence

6 FLASHES Control Internal Error

7 FLASHES Flame rod shorted to ground

8 FLASHES Low secondary voltage supply

If an internal control failure is indicated, replace the ignition control.

Use this diagnostic system in conjunction with “TROUBLESHOOTING” and the “SEQUENCE OF OPERATION” to troubleshoot the water heater.

ELECTRICAL SERVICING

Label all wires prior to disconnection when servicing controls.

Wiring errors can cause improper and dangerous operation.

Verify proper operation after servicing.

32

FOR YOUR INFORMATION

START UP CONDITIONS

Smoke/Odor

It is not uncommon to experience a small amount of smoke and odor during the initial start-up. This is due to burning off of oil from metal parts, and will disappear in a short while.

Strange Sounds

Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not necessarily represent harmful or dangerous conditions.

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.

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.

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.

Contact the local water heater supplier or service agency for further information concerning an Anode Replacement Kit and this chlorination treatment.

If hot water odor persists after anode replacement and chlorination treatment, we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem.

Do not remove the anode rod leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.

“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.

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).

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.
