DANGER

DO NOT store or use gasoline or other flammable, combustible, or corrosive vapors and/or liquids in the vicinity of this or any other appliance.

DO NOT install any damaged venting system components. If damage is evident then please contact the supplier where the water heater was purchased or the manufacturer listed on the rating plate for replacement parts.

Use only vent terminals provided or factory authorized terminals for venting this water heater.

This water heater is equipped with an adjustable thermostat to control water temperature. Hot water temperatures required for automatic dishwasher and laundry use can cause scald burns resulting in serious personal injury and/or death. The temperature at which injury occurs varies with the person’s age and the time of exposure. The slower response time of disabled persons increases the hazards to them. NEVER allow small children to use a hot water tap, or to draw their own bath water.NEVER leave a child or disabled person unattended in a bathtub or shower.

Failure to properly install the vent and air intake (if applicable) system could result in property damage, personal

DO NOT attempt to use this water heater with any gas other than the type listed on the rating plate. Do not attempt to convert this water heater for use with a gas other than the type for which it is equipped. Failure to use the proper gas can create an unsafe condition resulting in property damage, bodily injury, or death. Consult your local gas supplier or gas company if there are any questions.

DO NOT operate this water heater if the input rate exceeds the rate shown on the water heater rating plate.

This water heater contains very hot water under high pressure. Do not unscrew any pipe fittings nor attempt to disconnect any components of this water heater without positively assuring the water is cool and is not under pressure. Always wear protective clothing and equipment when installing, starting up or servicing this water heater to prevent scald injuries. Do not rely on the temperature gauges to determine the temperature. Do not touch any components unless they are cool.

This water heater must be properly vented and connected to an approved vent system in good condition. DO NOT operate water heater with the absence of an approved vent system. A clean and unobstructed vent system is necessary to allow noxious fumes that could cause injury or loss of life to vent safely and will contribute toward maintaining the water heater’s efficiency.

WARNING

This water heater needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air. Insufficient air supply will cause a recirculation of combustion products resulting in contamination that may be hazardous to life. This will result in carboning or sooting of the combustion chamber, burners, and flue tubes and creates a risk of asphyxiation.

This water heater requires its own separate venting system. DO NOT connect the exhaust vent into an existing vent pipe or chimney.

Water heater materials of construction, products of combustion and the fuel contain carbon monoxide, nitrogen

oxides, aldehydes and/or other toxic or harmful substances which can cause death or serious injury and which are ONLY

known to the state of California to cause cancer, birth defects and other reproductive harm. Always use proper safety clothing, respirators and equipment when servicing or working nearby this water heater.

Flammable items, pressurized containers or any other potential fire hazardous articles must never be placed on or adjacent to the water heater. Open containers of flammable material should not be stored or used in the same room

with this water heater.

REFERENCE

Insulation blankets are not required for this water heater. This water heater meets or exceeds the ASHRAE/IES 90.1b (latest edition) standards with respect to insulation and standby loss requirements.

Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink before you use any electrical appliance, which is connect to the hot water system. If hydrogen is present, there will be an unusual sounds such as air escaping through the pipes as hot water begins to flow. Do not smoke or have open flame near the faucet at the time it is open.

WARNINGFOR

IF YOU SMELL GAS:

Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closetsVERSIONand areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor.

∙ DO NOT try to light any appliance.

∙ DO NOT touch any electric switch; do not use any telephone in your building.

∙ Immediately call your gas supplier from a telephone in another building. Follow the gas supplier’s

INTERNETinstructions.

If you cannot reach your gas supplier, call the fire department.

DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!

SECTION III: GENERAL INFORMATION

FEATURES

This water heater contains the following features:

MAIN POWER ON/OFF SWITCH – The front panel of this water heater has a lighted ON/OFF switch, which is illuminated when the main power is turned on to indicate power to the water heater.

the burner. The Hot Surface Ignition System (HSI) then ignites the gas/air fuel mixture to produceONLYflue products (combustion). The flame sensor signals the ignition module (described below), that a flame is present.

COMBUSTION SYSTEM –Thiswater heater is equipped with aself-compensatingnegative pressure pre-mix

combustion system. As the blower operates, air is drawn in through the air intake and into a venturi, which pulls gas

from the gas valve. The gas and air is then mixed in the combustion blower and sent through the transition tube into

IGNITION MODULE – The ignition module provides the timing for the combustion system. A sequence of operation(S-OP)is described in “Section IX - Operating Instruction.” As the combustion system progresses through theS-OP,LED’s illuminate, allowing accuratetrouble-shootingshould the need arise. If a failure occurs, the system will “blink” the LED that corresponds to the failure as described in the “Section XI Troubleshooting Guide.”

ADJUSTABLE THERMOSTAT – This water heater is equipped with an adjustable thermostat to control water

temperature. Hot water temperatures required for automatic dishwasher and laundry use can cause scald burns

resulting in serious personal injury and/or death.

FOR

REFERENCE

 

 

 

The temperature may be adjusted from about 80°F to about 180°F. The thermostat was adjusted to 120°F before the

water heater was shipped from the factory. It is recommended that lower temperatures be used to avoid the risk of scalding. Refer to the “Warnings”VERSIONand the section on SCALDING in “Section V - Water Connections.” It is further

recommended, in all cases, that the water temperature be set for the lowest temperature, which satisfies your hot water needs. This will also provide the most energy efficient operation of the water heater and minimizes scale formation.

Setting the water heater temperature at 120°F will reduce the risk of scalds. Some states require setting the specific lower temperatures.

Should the high limit switch activate, it must be manually reset. This can be accomp lished by turning the main power on/off switch to the off position and then back to the on position and allowing the water temperature of the tank to drop below 160°F.

The top immersionINTERNETwell of the single bulb controller also contains the high limit (energy cutoff) sensor. The high limit switch interrupts the main burner gas flow should the water temperature reach approximately 200°F.

Contact your qualified installing contractor, service provider or manufacturer listed on the rating plate if continued high limit switch operation occurs.

SERVICE PANEL – The service panel is located behind the service panel access cover, which is located by the exhaust collector near the bottom of the water heater. This panel contains a differential pressure switch that monitors the pressure across the exhaust orifice. A collector high limit switch is used to monitor the ambient temperature between the first pass collector and the exhaust collector. This is a manuallyre-settableswitch. If this switch continues to trip, please contact an authorized service agency.

6

LATCHES – The latches allow easy access for servicing the water heater from the top. Simply remove the two latches for servicing andre-latchupon completion. No tools are required to obtain access to the top of the water heater.

All dishwashingINTERNETmachines meeting the National Sanitation Foundation requirements are designed to operate with water flow pressures between 15 and 25 pounds per square inch. Flow pressures above 25 pounds per square inch, or below 15 pounds per square inch, will result in improperly sanitized dishes.

The National Sanitation Foundation also recommends circulation of 180°F water. Where this is done, the circulation should be very gentle so that it does not cause any unnecessary turbulence inside the water heater. The circulation should be just enough to provide 180°F water at the point of take-offto the dishwashing machine. Adjust flow by means of the valve in the circulation line.

∙ Liquefied petroleum gases/propane gas and natural gas have an odorant added by the

 

 

gas supplier that aids in detection of the gas.

 

 

 

 

 

 

∙ Most people recognize this odor as a “sulfur” or “rotten egg” smell.

 

 

 

 

 

 

∙ Other conditions, such as “odorant fade” can cause the odorant to diminish in

 

 

intensity, or “fade”, and not be as readily detectable.

 

 

 

 

 

 

∙ If you have a diminished sense of smell, or are in any way unsure of the presence of

 

 

gas, immediately contact your gas supplier from a telephone in another building.

for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas.

 

 

Be sure to smell next to the floor.

 

 

 

 

 

 

 

IF YOU SMELL GAS:

 

 

 

 

 

Do not try to light any appliance.

Do not touch any electric switch; do not use any telephone in your building.

If you cannot reach your gas supplier, call the fire department.VERSION

DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!

INTERNET WARNING

This water heater must be located in an area where leakage of the tank, water line connections, or the combination temperature and pressure relief valve will not result in damage to the area adjacent to the water heater or to lower floors of the structure. When such locations cannot be avoided, a suitable drain pan must be installed under the water heater. The drain pan depth must be suitable for draining and collecting water, and have a minimum length and width of at least four (4) inches (10.0 cm) measured from the jacket of the water heater. The drain pan, as described above, can be purchased from your plumbing professional. The drain pan must be piped to an adequate drain. The piping must be at least ¾ inch (2.0 cm) in diameter and pitched for proper drainage.
