Rinnai RL94E - Manual (Page 5)

VB Series Outdoor LS Manual 5
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 a direct vent appliance 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 temperature controller is highly
recommended. The temperature 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.
