FEATURES AND BENEFITS Congratulations on purchasing the Technologically Advanced, Temperature Controlled, Rinnai Hot Water System. x 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. x 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.
IMPORTANT INFORMATION Excessively hot water is dangerous, especially for young children and the infirm. The water heater allows you to control the temperature of your hot water to safe levels. Water temperature over 50ºC can cause severe burns instantly or even death from scalding. Children, disabled and the elderly are at the highest risk of being scalded by excessively hot water. Always test the temperature of the water before bathing or showering.
IMPORTANT INFORMATION Always check water temperature before use. Hot water may go cold without warning at very low water flows (less than 3 l/min.) OFF Refer to warning about hot water on page 16 for important safety information. The Infinity 16i controls the water temperature automatically. For high temperatures it may reduce the flow. The water from the hot tap may be reduced after the temperature shown on the remote control is raised.
TEMPERATURE CONTROLS The purpose of a Temperature Controller is to enable the user to have complete control over the hot water supply. Used correctly, the Infinity will supply hot water at the temperature selected, even when the water flow is varied, or when more than one tap is used. Adjustments to the operation of your hot water unit can be made with any of the Temperature Controllers. Each Temperature Controller can be individually programmed.
TEMPERATURE CONTROLS - OPERATING Remote temperature controllers are a feature that provides control over the water temperature. The Rinnai Infinity 16i water heater can be operated with 1, 2, or 3 temperature controllers. The controller MC-45-SR-EU comes as standard with this water heater installed into the front panel. Digital Monitor Priority Indicator Priority Button Indicates the temperature selected. Error message flashes in the event of a fault.
TEMPERATURE CONTROLS - OPERATING Using the Temperature Controllers. Press the ON/OFF button on a temperature controller. The system will become active, the temperature will default to 400C and the controller that turned the system on will have priority. The temperature setting on the controller will light up. Adjusting Temperature Simply press the Hot Water Temperature Up or Down arrow button until the desired temperature is displayed on the digital display.
TEMPERATURE CONTROLS - OPERATING Using 2 or more Temperature Controllers. Switching the system ON. The hot water system and all controllers can be switched ON and OFF from any controller by pressing the ON/OFF button as shown. When the system is turned ON the water temperature display will be lit. . During normal operation the system is left ON. Do not push the ON/OFF button when water is running. Ensure the system is switched On by verifying the temperature display is lit.
TEMPERATURE CONTROLS - INFORMATION Do not push the ON/OFF button on the Master controller after transferring priority of temperature selection to a Secondary controller as the system will shut down. Temperature priority can not be switched to another controller when the water is flowing through the water heater.
CARING FOR THE INFINITY Maintenance Even if there does not seem to be a problem with the water heater it is required in the UK that all gas appliances are serviced every year by a certified gas engineer. This is to ensure continued safety of the gas appliance. If you need a recommended service engineer contact Rinnai or your supplier. Care When the appliance casing, operation panel, and remote controls surfaces become dirty gently wipe them clean with a soft, damp cloth.
ERROR MESSAGES Rinnai water heaters have the ability to check their own operation continuously. If a fault occurs, an error code will flash on the Digital Display if you have temperature controllers installed. This assists with diagnosing the fault, and may enable you to overcome a problem without a service call. Please quote the code displayed when enquiring about service. Some of these remedies can not be checked by the user because they require the front to be taken off of the unit.
ERROR MESSAGES Troubleshooting without controllers If you have not installed temperature controllers and experience the following symptoms, please carry out the suggestions below. If symptoms continue, please contact Rinnai for advice. Fault Remedy Heater does not attempt Check the power is on at the heater. to start at all.

OPERATION PRINCIPLE HOT WATER SUPPLY OPERATION Ignition Press ON/OFF Button of Remote Controller to turn on unit and the remote controller display and priority LED will light up. When a hot water tap is opened the Water Flow Sensor revolves and sends a pulse signal to the Printed Circuit Board (PCB.) When the PCB detects water flow it begins the ignition process with the Combustion Fan Motor starting first.
MAIN COMPONENTS 1. Gas Control Unit 1.1 Modulating Valve This device is used by the PCB to adjust the volume of gas to the burner in proportion to the volumetric flow rate of water in order to maintain a supply of constant temperature hot water amid changes in water flow rates and incoming temperatures. 1.2 Change-over Solenoid Valves Additional solenoid valves are included to section the burner and stage the control in 3 steps.
MAIN COMPONENTS 3. Thermal Fuse The thermal fuse is an electric link which must be intact for the unit to operate. If the thermal fuse reaches a set temperature it will melt and the unit will shut down. The thermal fuse must be replaced if it melts. It is to protect against over heating and heat exchanger splits where water may leak out and be super heated into steam. 4. Overheat Safety (Bi-metal Switch) This Bi-metal Switch is fixed at the bend of the Heat Exchanger hot water outlet.
