F
The Rinnai is one of the most advanced water heaters available. It supplies hot water
continuously at the temperature preset in the unit or at the temperature set on the
optional remote controller(s). Installation of remote controllers are recommended for
optimum functionality.
F
The Rinnai never runs out of hot water, while electricity, water and gas supplies are
connected. The Rinnai produces hot water whenever the hot water tap is open.
F
The gas burner lights automatically when the hot water tap is opened and shuts off when
the tap is closed. Ignition is electronic, there is no pilot light. When the hot water tap is
off, no gas is used, you save energy and money with the Rinnai.
F
The temperature of the outgoing hot water is constantly monitored by a built in sensor.
If the temperature of the outgoing water rises to more than 6
temperature (shown on the digital remote controller) the gas burner automatically shuts
off. The gas burner will re-ignite once the outgoing hot water temperature falls below the
selected temperature.
F
Built into the microprocessor of the Rinnai is the ability to LIMIT THE MAXIMUM
