The T-K3-OS/SP Water Heater is an instantaneous, tankless water heater designed to
efficiently supply endless hot water for your needs.
•
The principle behind the T-K3-OS/SP Water Heater 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 automatically
ignites the burner.
5. Water circulates through the heat
exchanger and then gets hot.
6. The computer will modulate the
gas supply valve and water flow
to produce the right amount of hot
water at the correct temperature.
7. When the tap is turned off, the
unit shuts down.
