Released in 2003, the T-K Jr. is the smallest water heater in the Takagi tankless line. But this small, but powerful unit - with gas inputs up to 140,000 BTU per hour - can meet all the hot-water needs of a small American home or apartment with one or two bathrooms, as well as smaller commercial applications. Designed to virtually do anything a 40-gallon tank-type water heater can do and more, the compact, wall mounted T-K Jr. can support hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances. The T-K Jr. has an energy factor of 0.81-0.83. At an average (rise in temperature) of 60°F in warmer areas - where the winter ground water is 60°F and with the output set at 120°F - the unit will provide 3.8 GPM, or 228 GPH. In colder areas where the input temperature may be 40°F or less you can expect a flow rate of about 2.7 GPM or 162 GPH.

Cost-efficient and environmentally friendly, the T-K Jr. can be converted into a direct-vent unit by using the optional TV09 conversion kit for installation in a garage, a utility closet or any confined space in which makeup air may be limited. Please refer to "Accessories" for more information on venting options.

Using the average of 60°F input water cited above, the T-K Jr. can provide enough hot water for one shower and a lavatory basin at a time; or one low-flow shower (2.5 GPM or less) and an appliance, such as a dishwasher or washing machine, at the same time. For much colder input temperatures, such as 40°F or lower, this unit can provide endless hot water for consecutive uses; that is, running only one major fixture at a time. Please refer to the flow charts for specific rates.

The four preset temperatures on the unit are: 113°F, 122°F, 140°F, and 182°F. To achieve any temperatures other than those presets, your client will require the TK-RE20 temperature controller.

For Energy Star Certifications please follow Specification Sheets and Literature that is dated 2009 ONLY. As of March 27, 2009, ONLY the T-K3-Jr Liquid Propane model qualifies as an Energy Star unit.

ACCECORIES

	TK-TV09 Direct Vent Conversion Kit The TK-TV09 Direct venting kit converts the tankless unit from a conventional vent system to a direct vent (or sealed combustion) system.
	TK-TV04 Outdoor Ventilator Cap The TK-TV04 vent cap kit is installed on the top of the unit to allow outside installation of the tankless unit.
	TK-RE02 Temperature Remote Controller The TK-RE02 Temperature Remote Controller allows the output temperature to be adjusted beyond the factory settings, and works as a diagnostic tool for error codes.
	TK-KPWH4 Cap Wall Thimble With Hood The TK-KPWH4 T-Vent wall thimble with hood termination is used when venting out through the wall and are compatible with the T-Vent pipe system.
	TK-IV-01 Isolation Valves & Pressure Relief Valve Isolation valves are used to isolate a unit for service. The Pressure Relief Valve is to help protect the unit and release if the pressure in the tankless water heater or hot water system exceeds 150 psi.
	TK-BF01 Exhaust Backflow Prevention Kit The TK-BF01 prevents cold air from entering the vent and causing heat exchanger to freeze.
