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 front 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 with the

manufacturer or its local representative.

This equipment is an on-demand, tankless water heater designed to efficiently supply

endless hot water for your needs.

The 110 Indoor (T-KJr2-IN), 310 Indoor (T-K4-IN) and 510 Indoor (T-D2-IN) models are

to be only installed indoor (direct-vent convertible). The 110 Outdoor (T-KJr2-OS), 310

The principle behind tankless water heaters is simple:

1. A hot water tap is turned on.

2. Water enters the heater.

3. The water flow sensor detects the water flow.

4. The computer initiates the fan motor 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 circulates through the heat exchanger and then gets hot.

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

modulates the gas and water valves to ensure proper output water temperature.

INSTALLATION

GENERAL

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. 8 for proper clearances.

5. The water heater must be installed in a location where the proper amount of combustible air will be available to it at all times without obstructions.

6. The electrical connection requires a means of disconnection, to terminate power to the water heater for servicing and safety purposes.

7. 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. 15).

8. Particles from flour, aerosols, and other contaminants may clog the air vent or reduce the functions of the rotating fan and cause improper burning of the gas. Regularly ensure that the area around the unit is dust- or debris-free; regular maintenance is recommended for these types of environment.

9. If you will be installing the water heater in a contaminated area with a high level of dust, sand, flour, aerosols or other contaminants/chemicals, they can become airborne and enter and build up within the fan and burner causing damage to the water heater.

10. For the 110 Indoor (T-KJr2-IN), 310 Indoor (T-K4-IN) and 510 Indoor (T-D2-IN) models:

 These units may be converted to a direct-vent (sealed combustion) appliance by installing a

direct-vent conversion kit Part No. 9007667005 (TK-TV10) which will bring in all required combustible air from outside the building. When installing the direct-vent conversion kit, please follow all instructions included with the kit.

 If the water heater is used as a direct-vent appliance, the unit requires a 3” combustible air

supply pipe. The intake pipe must be sealed airtight. Air supply pipe can be made of ABS, PVC, galvanized steel, corrugated aluminum, corrugated stainless steel or Category III stainless steel.

 Terminating the venting through a sidewall is recommended for the direct-vent system.  Running the exhaust vent and the intake pipe parallel is recommended.  Terminating the exhaust and intake on the same wall / surface is recommended.

Terminating in the same pressure zone allows for pressure balancing, which prevents nuisance shutdowns.

11. For the 110 Outdoor (T-KJr2-OS), 310 Outdoor (T-K4-OS) and 510 Outdoor (T-D2-OS) models:

 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 combustion chamber, unless the system is direct-vented.

 The manufacturer does not recommend 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 enough combustion air and proper ventilation.  Keep the area around the water heater clean. When dust collects on the

flame sensor, the water heater will shut down on an error code.

 If the above conditions cannot be met, use the direct vent conversion kit

Part No. 9007667005 (TK-TV10).

 Place the unit for easy access for service and maintenance.  A drain pan, or other means of protection against water damage, is

 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.

VENTING INSTRUCTIONS

-General-

CAUTION

The water heater must be vented in accordance with the section “Venting of Equipment" of the latest edition of the National Fuel Gas Code: ANSI Z223.1/NFPA 54 in the United States and/or Section 7 of the CAN/CSA B149.1 Natural Gas and Propane Installation Code in Canada, as well as applicable local building codes. The manufacturer recommends the “T-Vent” line manufactured by TAKAGI (Refer to “T-Vent” brochure for details). However, the following are also UL listed manufacturers: ProTech Systems Inc. (FasNSeal), Flex-L Inc., Z-Flex Inc. (Z-Vent III), Metal-Fab Inc., and Heat-Fab Inc. (Saf-T Vent).

General rules for venting water heaters are:

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.

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.

 Place the water heater as close as possible to the vent terminator.  The vent collar of the water heater must be fastened directly to an unobstructed vent pipe.  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.

 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.  For rooftop venting, a rain cap or other form of termination that prevents rain water from

entering into the water heater must be installed.

 Do not common vent or connect any vent from other appliances to the water heater vent.

General rules for vent terminations:

 Avoid locating the water heater vent terminator 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 terminator so that it cannot be blocked by any debris, at any time. Most

codes require that the terminator be at least 12 inches above grade, but the installer may determine if it should be higher depending on the job site condition and applicable codes.

 A proper sidewall terminator is recommended when the water heater is vented through a

sidewall.

 Regarding the clearances from the exhaust terminator to the air inlet or opening, refer to

the next few pages.

This is a Category III appliance and must be vented accordingly. The vent system must be sealed air tight. All seams and joints without gaskets must be sealed with high heat resistant silicone sealant or UL listed aluminum adhesive tape having a minimum temperature rating of 350°F. 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 any 4” vent

approved for use with Category III or Special BH type gas vent.

 Follow the vent pipe manufacturer’s instructions when installing the vent pipe.  Do not common vent this appliance with any other vented appliance (Do not terminate vent

into a chimney. If the vent must go through the chimney, the vent must run all the way through the chimney with Category III approved or Special BH vent pipe).

 When the horizontal vent run exceeds 5 ft., support the vent run at 3 ft. intervals with

overhead hangars.

 The maximum length of exhaust vent piping must not exceed 50 ft. (deducting 5 ft. for each

elbow used in the venting system). Do not use more than 5 elbows.

*For each elbow added, deduct 5 ft. from max. Vent length.

CAUTION

For sidewall terminations

terminations (e.g. multi-unit systems), an exhaust termination must be at least 1 ft. away from another exhaust termination. An exhaust termination must also be at least 2 ft. away from an inside corner (if the adjacent wall is less than 2 ft. of length, the minimum required distance away from the inside corner will be equal to the length of that adjacent wall).

In the absence of such codes, the following clearances can be used as guidelines. Local codes supersede these guidelines.

corner

terminations that use two separate penetrations for the intake and exhaust, distance the intake and exhaust terminations at least 3 ft. away from each other, no matter the orientation.

corner

Direct vent termination

terminations that combine the intake and exhaust into a single penetration, space each direct-vent termination at least 1 ft. away from each other, no matter the orientation. A direct-vent termination must also be at least 2 ft. away from an inside corner (if the adjacent wall is less than 2 ft. of length, the minimum required distance away from the inside corner will be equal to the length of that adjacent wall).

2ft.

termination

sidewall terminations should be at least 2 ft. away from an opposite surface/wall. Do not place the termination directly in front of an opening into a building.

For rooftop terminations

termination

direct-vent installations) space all exhaust and intake terminations in accordance with local codes. An exhaust termination must be spaced from a wall or surface in accordance with local codes as well. In the absence of such a code, an exhaust termination must be a horizontal distance of at least 2 ft. away from a wall or surface.
