INTRODUCTION

• This manual provides information necessary for the installation, operation, and maintenance

of the water heater.

• The model description is listed on the rating plate which is attached to the side panel of the

water heater.

• Please read all installation instructions completely before installing this product.

• If you have any problems or questions regarding this equipment, consult the manufacturer or

its local representative.

• This appliance is an on-demand, tankless water heater. It is designed to efficiently supply

endless hot water for your needs.

• The 110C, 310C, and 510C models are only to be installed indoors with concentric venting.

• The principle behind tankless water heaters is simple:

*This diagram illustrates tankless water heater design concepts only and does not accurately represent

the water heater’s physical description.

1. A hot water fixture is turned on.

2. Water flows through the heater.

3. The water flow sensor detects the water flow.

4. The computer initiates the fan motor and gas valve to let gas flow through the heater and sends a

signal to the igniter to create an ignition spark.

5. The gas ignites and flames appear within the burner chamber.

6. Water is heated as it flows through the heat exchanger.

7. Using thermistors to measure temperatures throughout the water heater, the computer modulates

the gas and water valves to ensure proper output water temperature and hot water outflows.

8. When the fixture is turned off, the unit shuts down.

SAFETY GUIDELINES

SAFETY DEFINITION

GENERAL

1. Follow all local codes, or in the absence of local codes, follow the current edition of the National Fuel Gas Code:

ANSIZ223.1/NFPA54intheUSAorCAN/CSAB149.1,NaturalGasandpropaneinstallationcodeinCanada.

2. Properly ground the unit in accordance with all local codes or in the absence of local codes, with the current

edition of the National Electrical Code: ANSI/NFPA 70 in the USA or CSA standard C22.1 Canadian Electrical

Code Part 1 in Canada.

3. Carefully plan where you intend to install the water heater. Please ensure:

• Your water heater will have enough combustion air and proper ventilation.

• Locate your heater where water leakage will not damage surrounding areas. (Please refer to p. 8.)

4. Check the rating plate for the correct GAS TYPE, GAS PRESSURE, WATER PRESSURE and ELECTRIC RATING. If

this unit does not match your requirements, do not install and consult with the manufacturer. The water

heater is configured only for use with Natural Gas at the factory. If the appliance is used with propane gas,

conversion to propane gas with an included conversion kit (LP Conversion Kit: 319143-580) is required. The

conversion must be done by a qualified service agent or a gas utility serviceman in accordance with this

instruction and all codes and requirements of the authority having jurisdiction. Failure to follow instructions

could result in serious injury or property damage. The agent performing this work assumes responsibility for

this conversion. (Refer to the gas conversion leaflet.)

5. If any problem should occur, turn off all hot water fixtures and turn off the gas. Then call a trained technician

or the Gas Company or the manufacturer.

WARNING

• Water temperatures over 125 °F (52 °C) can cause severe burns instantly or death from

scalding. The water temperature is set at 120 °F (50 °C) from the factory to minimize any

scalding risk. Before bathing or showering always check the water temperature.

• Do not store or use gasoline or other flammables, vapors, or liquids in the vicinity of this

appliance.

• Do not reverse the water and/or gas connections as this will damage the gas valves and

can cause severe injury or death. Follow the diagram on p. 20 when installing your water

heater.

• The conversion to propane must be done by a qualified service agent or a gas utility

serviceman in accordance with this instruction and all codes and requirements of the

authority having jurisdiction. Failure to follow instructions could result in serious injury

or property damage. The qualified agent performing this work assumes responsibility

for this conversion.

• Do not use this appliance if any part has been in contact with or been immersed in

water. Immediately call a licensed plumber, a licensed gas fitter, or a professional service

technician to inspect and/or service the unit if necessary.

• Do not disconnect the electrical supply if the ambient temperature will drop below

freezing. The Freeze Protection System only works if the unit has electrical power. The

warranty will not be covered if the heat exchanger is damaged due to freezing. Refer to

the section on the Freeze Protection System on p. 37 for more information.

INSTALLATION

GENERAL

1. Follow all local codes, or in the absence of local codes, follow the current edition of the National Fuel

GasCode:ANSIZ223.1/NFPA54intheUSAorCAN/CSAB149.1,NaturalGasandpropaneinstallation

code in Canada.

2. All gas water heaters require careful and correct installation to ensure safe and efficient operation.

This manual must be followed exactly. Read the “Safety Guidelines” section.

3. The manifold gas pressure is preset at the factory. It is computer controlled and should not need

adjustment.

4. Maintain proper space for servicing. Install the unit so that it can be connected or removed easily.

Refer to the "Clearances" section on p. 9 for proper clearances.

5. The electrical connection requires a means of disconnection, to terminate power to the water heater

for servicing and safety purposes.

6. Do not install the unit where the exhaust vent is pointing into any opening in a building or where the

noise may disturb your neighbors. Make sure the vent termination meets the required distance by

local code from any doorway or opening to prevent exhaust from entering a building. (Refer to p. 11,

16, and 17.)

7. Carefully plan the installation location of the heater and vent terminations. Particles from flour,

aerosols, lint, and other contaminants may clog the air intake. This could reduce the operation of the

fan causing improper combustion and reduced life of the water heater. Ensure that the area around

the heater and vent termination is free of dust and debris. Regular maintenance is recommended is

environments with these items in the air.

8. For the 110C, 310C, and 510C models: A condensate collector and trap (100266140 & 100266139)

are required to be installed in the venting system when there is more than 8 feet (2.4 m) of equivalent

vent length, not including the sidewall termination. 87° elbow is equivalent to 5 ft. (1.5 m) of vent

length. The condensate collector must be installed on the heater's flue. The condensate trap and

collector are required on all vertical installations.

• Installation and service must be performed by a qualified installer (for

example, a licensed plumber or gas fitter). Otherwise, the warranty will be

void.

• The installer (licensed professional) is responsible for the correct installation

of the water heater and for compliance with all national, state / provincial,

and local codes.

• The manufacturer does not recommend installing the water heater in a pit or

location where gas and water can accumulate.

• Do not have the vent terminal pointing toward any operating window, door, or

opening into a building.

• Do not install next to any source of airborne debris, such as a clothes dryer, that

can cause debris to be trapped inside the unit cabinet.

• The manufacturer does not suggest installing the water heater in an attic due

to safety issues. If you install the water heater in an attic:

• Make sure the unit will have proper ventilation.

• Keep the area around the water heater and its termination clean. When

dust collects on the flame sensor, the water heater will shut down and

produce an error code.

• Place the unit for easy access for service and maintenance.

• A drain pan, or other means of protection against water damage, is

recommended to be installed under the water heater in case of leaks. The

manufacturer is not responsible for damage due to water leak.

WARNING

• The warranty will not cover damage caused by water quality.

• Only potable water or potable water / glycol mixtures can be used with

this water heater. Do not introduce pool or spa water, or any chemically

treated water into the water heater.

• Water hardness levels must not exceed 7 grains per gallon (120 ppm) for

single family domestic applications or more than 4 grains per gallon (70

ppm) for all other types of applications. Water hardness leads to scale

formation and may affect / damage the water heater. Hard water scaling

must be avoided or controlled by proper water treatment.

• Water pH levels must be between 6.5 and 8.5.

• Well water must be treated.

• Do not install the unit where water, debris, or flammable vapors may get into

the flue terminal.

• Although the water heater is designed to operate with minimal sound, the

manufacturer does not recommend installing the unit on a wall adjacent to a

bedroom, or a room that is intended for quiet study or meditation, etc.

• Locate your heater close to a drain where water leakage will not do damage

to surrounding areas. As with any water heating appliance, the potential for

leakage at some time in the life of the product does exist. The manufacturer

will not be responsible for any water damage that may occur. If you install a

drain pan under the unit, ensure that it will not restrict the combustion air flow.
