*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.

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.
• 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.
WARNING • 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.

WARNING
CAUTION
•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.
•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.

VENTING INSTRUCTIONS
-General-
DANGER
CAUTION
•Improper venting of this appliance can result in excessive levels of carbon monoxide which can result in severe personal injury or death.
•Improper installation can cause nausea or asphyxiation, severe injury or death from carbon monoxide and flue gases poisoning. Improper installation will void product warranty.
When installing the vent system, all applicable national and local codes must be followed. If you install thimbles, fire stops or other protective devices and they penetrate any combustible or noncombustible construction, be sure to follow all applicable national and local codes.
The water heater must be vented in accordance with the section “Venting of Equipment" of the current editionoftheNationalFuelGasCode:ANSIZ223.1/NFPA54intheUnitedStatesand/orSection7ofthe
CAN/CSA B149.1 Natural Gas, propane installation code in Canada, as well as applicable local building codes. The water heater is designed for a concentric venting system, which uses one pipe system with two ducts for combustion air and exhaust air. The manufacturer approves the use of Centrotherm Eco
Systems Direct Vent APNC35 venting systems on new installations. This system is furnished through the heater manufacturer. See the table below for certified vent terminations.
General rules for venting water heaters:
•Place the water heater as close as possible to the vent termination.
•Do not weld the vent pipe to the water heater’s vent collar.
•Do not cut the vent collar of the unit.
•The vent must be easily removable from the top of the water heater for normal service and inspection of the unit and vent system.
•The water heater vent must not be connected to any other gas appliance or vent stack.
•Avoid using an oversized vent pipe or using extremely long runs of the pipe.
•Do not common vent or connect any vent from other appliances to the water heater vent.
•The vent should slope towards the heater and condensate collector (100266139). The condensate trap (100266140) must be installed below the condensate collector's drain nipple to keep condensate from draining back into the heater's exhaust and causing damage. Condensate is corrosive and should be treated and disposed of according to local codes.
General rules for vent terminations:
•Avoid locating the water heater vent termination near any air intake devices. These fans can pick up the exhaust flue products from the water heater and return them to the building. This can create a health hazard.
•Locate the vent termination so that it cannot be blocked by any debris, at any time. Most codes require that the termination must be at least 12 in. (305 mm) above grade and anticipated snow line, but the installer may determine if it should be higher depending on the job site condition and applicable codes.
•A proper sidewall termination is recommended when the water heater is vented through a sidewall.
•Regarding the clearances from the exhaust termination to the air inlet or opening, refer to p 11, 16, and 17.

-Vent length and No. of Elbows-
This is a Category III appliance and must be vented accordingly. For best results, a vent system should be as short and straight as possible.
•This water heater is a Category III appliance and must be vented accordingly with concentric vent approved for use with Category III or Special BH type gas vent.
•Follow the vent pipe manufacturer's instructions and the instructions in this manual when installing the vent pipe.
•Do not common vent this appliance with any other vented appliance. (Do not terminate vent inside a chimney. If the vent must go through the chimney, it must run through the top of the chimney and terminate with the roof termination listed on page 10. Install per the vent manufacturer's instructions.)
•When the horizontal vent run exceeds 5 ft. (1.5 m), support the vent run at 3 ft. (0.9 m) intervals with overhead hangers.
•The maximum length of exhaust vent piping must not exceed 43 ft. (13.1 m) (deducting 5 ft. (1.5 m) for each 87° elbow used in the venting system). Do not use more than 4 pieces of 87° elbows.
