Introduction
The Rinnai Infinity hot water units represents the latest
technology in continuous flow, temperature controlled hot water.
Features
• The Rinnai Infinity 16i will NEVER RUN OUT of hot water. As long as electricity,
water, and gas supplies are connected, hot water is available when hot water taps
are open.
•
Built into the main micro-processor is the facility to LIMIT THE MAXIMUM TEM-
PERATURE of the hot water supplied. The water temperature may be set to vari-
ous temperatures. This is particularly useful when the hot water unit is installed
where young children or the infirm may be using the hot water. If required, the tem-
perature can be changed via the control pad on the front of the unit or with a local-
ised controller. For further information, please contact Rinnai.
•
Rinnai Infinity internal units are powered flue appliances. This makes them COM-
PACT , saving both floor and wall space.
•
The temperature of outgoing hot water is CONSTANTLY MONITORED by a
BUILT-IN SENSOR . If the temperature of the outgoing hot water rises to more than
55°C the burner is shut OFF and only turned ON again when the temperature falls
to below the selected temperature.
• The burner lights automatically when the hot water tap is opened, and extinguishes
when the tap is closed.
IGNITION IS ELECTRONIC , so there is no pilot light. When
the hot water tap is off, no gas is used.
• The 16i has a built in controller on the front of the unit for easy control. Two addi-
tional external temperature controllers can be mounted remotely from the heater.
This offers the following additional features:
Localised temperature setting.
Diagnostic message.
Error Codes.
• Temperatures selected at the controllers are retained in the SYSTEM MEMORY
when the controller gives up priority or the system is turned off. Temperatures over
55
0
C will revert to 55
0
C when power and/or priority is regained.
•
Operating NOISE LEVEL IS VERY LOW .
•
ERROR MESSAGES ARE DISPLAYED on the Temperature Controllers, assisting
with service.
