Description of Operation

The Rinnai water heater is one of the most advanced water heaters available. It provides a continuous supply of hot water at a preset temperature. This appliance is direct vent where air is brought in from the outside and combustion gases are exhausted to the outside.

While electricity, water, and gas supplies are connected, the Rinnai water heater produces hot water whenever a hot water tap is open.

Ignition is electronic. There is no pilot light consuming gas while the water heater is not being used. The gas burner lights automatically when the hot water tap is opened and goes out when the tap is closed.

Installation of the remote controller is highly recommended. The remote controller can set the temperature within a specific range and can provide error codes to diagnose any problems.

The temperature of the outgoing hot water is constantly monitored. The Rinnai water heater may adjust the water flow in order to maintain the temperature setting. The water flow may vary from summer to winter due to the difference in ground water temperature.
