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 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! Always check water temperature carefully before use. Refer to the WARNING ABOUT HOT WATER on "page 1" of this manual for important safety information. At low water flows, the hot water unit may extinguish without warning.
IMPORTANT INFORMATION S O L V E N T Max. 43°C 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. To clean your water controller(s) use a soft damp cloth with a mild detergent. Do Not use solvents! 49°C 50°C There is no need to turn the water controller(s) off after 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 MAXIMUM DELIVERY TEMPERATURES Rinnai continuous flow water heaters are factory pre-set to various maximum delivery temperatures depending on model and their intended application. For the majority of applications, the factory preset temperature is appropriate. In the unlikely event this is not the case this setting can be increased or decreased by an authorised person such as a licensed plumber. NOTE This does not apply to “50 degree compliant” or “Solar” models.
GENERAL WATER CONTROL INFORMATION Remote water controllers allow precise temperature control by the user. When used correctly, the hot water unit will deliver the selected temperature, even when the water flow is varied, or more than one tap is in use. Each water controller can be individually programmed, however the water heater can only deliver one set temperature at any time.

GENERAL INSTALLATION INSTRUCTIONS CO-AXIAL FLUEING FOR INTERNAL MODELS Rinnai internal models described in this manual must use the Co-Axial Rinnai FFU flue components. The use of non Rinnai FFU flue components may result in a dangerous situation and violates regulations. The FFU flue system must be installed in accordance with the ‘FFU Flue Installation Manual’ which is provided with the FFU flue terminal components FFWALLTERM or FFROOFCOWL.
CONDENSATE DRAIN (REU-KM’ MODELS ONLY) The INFINITY ENVIRO range water heaters generate condensate continuously at a rate of up to 5 litres per hour as a by-product of highly efficient gas burner system. This condensate must be drained via a pipe to a suitable point of discharge. Because the condensate is a by-product of gas combustion it is mildly acidic. For this reason copper tube and fittings MUST NOT be used as it will corrode.
CONDENSATE DRAIN (REU-KM’ MODELS ONLY) INTERCONNECTION OF CONDENSATE DRAIN LINES Condensate drain lines from multiple water heaters may be joined together provided they conform with the ‘INSTALLATION’ requirements on page 28.
WATER CONTROLLER INSTALLATION RINNAI WATER CONTROLLERS Water controllers are available as an optional extra. Universal and Deluxe water controllers can be used together and will function as described in the Operation Section of this manual. Please refer to page 7 to confirm the maximum number and combination of water controllers that can be fitted. NOTE Other manufacturers water controllers are NOT compatible with Rinnai water heaters. Water controllers MUST NOT be used with any Solar Boost water heater.
