Features and Benefits

Congratulations on purchasing the Technologically Advanced, Temperature Controlled, Rinnai Hot Water System.

ξ 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.

ξ Built into the main micro-processor is the facility to LIMIT THE MAXIMUM TEMPERATURE of the hot water supplied. The water temperature may be set to various 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 temperature can be changed via the control pad on the front of the unit or with a localised controller. For further information, please contact Rinnai.

ξ Rinnai Infinity internal units are powered flue appliances. This makes them COMPACT, saving both floor and wall space.

ξ 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.

ξ 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.

ξ The 16i has a built in controller on the front of the unit for easy control. Two additional external temperature controllers can be mounted remotely from the heater. This offers the following additional features:

Localised temperature setting. Diagnostic message.

Error Codes.

ξ 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 550C will revert to 550C when power and/or priority is regained.

ξ Operating NOISE LEVEL IS VERY LOW.

ξ ERROR MESSAGES ARE DISPLAYED on the Temperature Controllers, assisting with service.

ξ FROST PROTECTION device built in as standard.
