OPERATION MANUAL REGULATORY INFORMATION.............................................................................................. 4 WARNING ABOUT HOT WATER ........................................................................................... 4 FEATURES AND BENEFITS .................................................................................................. 5 IMPORTANT INFORMATION..................................................................................................
REGULATORY INFORMATION Your Rinnai Continuous Flow water heater has been certified by the Australian Gas Association. The A.G.A. Certification Number is shown on the data plate. This Appliance must be installed correctly by an authorised person. The installation of gas, water, and electricity must conform to local regulations. The installation must also comply with the instructions supplied by Rinnai. All dimensions referred to in these instructions are in millimetres, unless otherwise specified.
FEATURES AND BENEFITS Congratulations on purchasing the latest technology temperature controlled Rinnai continuous flow water heating system. • The Rinnai Continuous Flow water heater products NEVER RUN OUT of hot water. Whilst electricity, water and gas supplies are connected, hot water is available whenever hot water taps are open. • Built into the main micro-processor is the facility to LIMIT THE MAXIMUM TEMPERATURE of the hot water supplied. The water temperature may be limited to various values.
IMPORTANT INFORMATION S O L V E N T Max. 43°C To clean your water controller(s) use a soft damp cloth with a mild detergent. Whilst hot water outlets are open the set temperature may be lowered. However they cannot then be raised above 43°C. In addition transfer of 'priority' between controllers is not possible. These are safety features.
IMPORTANT INFORMATION NOTE The range of Rinnai continuous flow water heaters referred to in this manual are incompatible with solar water heating systems. A dedicated range of solar compatible continuous flow water heaters is available from Rinnai. OFF! At low water flows, the hot water unit may extinguish without warning. Opening the tap further will restart the appliance. Always check water temperature carefully before use.
OPERATION WITHOUT CONTROLLERS Rinnai Continuous Flow water heater products do not use a pilot light. When installed and operated without water controllers, the opening of any hot water tap will automatically start the appliance. Once water is flowing through the appliance the burner will be ignited by electronic ignition. When the hot water tap is closed and water flowing through the appliance has stopped the burner flame will extinguish.
GENERAL WATER CONTROL INFORMATION RADIO COMMUNICATIONS Rinnai wireless water controllers are classified as short range radio communications devices and referred to as Low Interference Potential Devices (LIPD’s) in AS/NZS 4268*. As such, they operate in the same radio frequency spectrum as many other devices classified as LIPD’s such as garage door openers and keyless automobile entry systems. Although interference with other LIPD's is unlikely, it is not guaranteed interference will not occur.
GENERAL WATER CONTROL INFORMATION Suggested temperatures are: Kitchen 50°C ~ 55°C*, Shower 37°C ~ 43°C * Temperature may not be available on all installations. Rinnai water heaters can be programmed to deliver higher temperatures via the kitchen controller. Contact Rinnai for more details. These temperatures are suggestions only. You may find higher or lower temperatures more comfortable. Maintaining lower temperatures helps save energy. To obtain water temperatures lower than 37°C simply add cold water.
