OPERATION

HOW IT WORKS

The Onsen 14L Indoor Gas Tankless Water Heater uses gas to heat water by burning a flame on the copper
heat exchanger. The incoming water is heated when it circulates through the heat exchanger before being
directed to the water outlet. The temperature of the exiting water can be increased or decreased via the
control panel of the water heater.
The temperature of the outgoing water can be adjusted between 95° F and 140° F (35° C and 60° C).
This gas water heater requires water pressure of 15 PSI and a flow rate of 0.67 gpm (2.5 l/min) to operate. The
unit will stay in operation until the flow drops below 0.53 gpm (2 l/min).
The burner ignition is electronic. The unit has no pilot light and consumes no gas when the heater is not being
used.
Air is brought into the unit from outside, efficiently burned with the appropriate source of fuel, and then
exhausted externally.
The unit's integrated control system constantly monitors the temperature of the water being produced and
adjusts the burner accordingly to deliver a stable supply of hot water.
The unit is highly flexible and provides hot water over a wide range of flow rates and incoming water
temperatures across the capacity range of the unit.
The unit has multiple protective functions such as no-load heating prevention, automatic shutdown in case of
accidental flameout, and automatic pressure relief to ensure safety and reliability.
