WARNINGS & 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.
WARNINGS & IMPORTANT INFORMATION Operational Safety Information IMPORTANT This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
WARNINGS & IMPORTANT INFORMATION IMPORTANT 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. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. OFF! Always check water temperature carefully before use.
WARNINGS & IMPORTANT INFORMATION FEATURES & BENEFITS Congratulations on purchasing the latest technology temperature controlled Rinnai continuous flow water heating system. • • • • • • • • • • Rinnai 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.
WATER TEMPERATURE CONTROL 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 pre-set 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” models.
WATER TEMPERATURE CONTROL Temperature Control 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. Only one MC model water controller can be designated as a ‘Master’ water controller and this is normally used in the kitchen.
WATER TEMPERATURE CONTROL UNIVERSAL WATER CONTROLLER (MC-601Q) OPERATION WATER HEATER 'IN USE' INDICATOR PREHEAT INDICATOR Indicates that the Smartstart preheater (when fitted) is activated. Indicates that a water heater is delivering hot water. DIGITAL MONITOR PREHEAT BUTTON Used to start and stop the Smartstart preheat unit (when fitted), See Smartstart Operation on page 11. Indicates the temperature selected. Error messages flash in event of a fault.
WATER TEMPERATURE CONTROL SMARTSTART PRE-HEAT SYSTEM The “Preheat” function works in conjunction with various Rinnai water heater models when the separately installed and optional Rinnai “Smartstart®” module is installed. PREHEAT BUTTON 1 7 3 2 5 Used to start and stop Smartstart preheater.
TROUBLE SHOOTING ERROR CODES Your Rinnai Continuous Flow water heaters has a self diagnostic capability. If a fault occurs, an Error Code will flash on the digital monitor of your water controllers or on the status monitor * on the front cover of the water heater. 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.
TROUBLE SHOOTING No power display Wireless Water Controller (when fitted) When power to the water heater is disconnected the LCD of all wireless water controllers will display as shown to the right. Check that the power is available, and that the water heater is plugged in with the power point turned ‘on’. Troubleshooting Without Water Controllers If you have no water controllers and experience the following symptoms, carry out these suggestions. If the symptom continues, contact Rinnai for advice.

GENERAL INSTALLATION INFORMATION INSTALLATION, SERVICE AND REMOVAL MUST BE BY AN AUTHORISED PERSON ONLY. NOTE It is the installer’s responsibility to ensure all current AS/NZS 5601 requirements are met. Remove transit protection. Check for damage, if any is found DO NOT install and contact supplier.
GENERAL INSTALLATION INFORMATION Service Connection Points Refer to "Table 2. Supply, Flow rates, Weights & Flow & Service Connections" on page 27 for model specific connection / fitting dimension details. An Approved full flow isolation valve and disconnection union MUST BE fitted to the cold water and gas inlets. A non return valve is not required on the water inlet unless required by local regulations. Isolation Valves MUST NOT be fitted directly to the appliance.
GENERAL INSTALLATION INFORMATION HOT WATER DELIVERY TEMPERATURE Local regulations and or the requirements of AS/NZS 3500 MUST BE addressed regarding the temperature limitations of hot water supplied to areas used primarily for personal hygiene. The temperature of water to these areas may be limited to 50°C or less.

FLUEING Horizontal Obstructions AS/NZS 5601 ‘Gas Installations’ stipulates a minimum horizontal clearance of 500 mm between a building structure and obstruction facing the terminal. For correct operation of Rinnai external continuous flow water heaters such a building structure MUST ‘obstruct’ the full front cover height of the appliance (for appliance dimensions, refer to "Table 1. Appliance Dimensions" on page 26), or extend vertically above and below the front cover as shown below.
WATER CONTROLLER INSTALLATION GENERAL INFORMATION IMPORTANT Other manufacturers water controllers are NOT compatible with Rinnai water heaters. Water controllers MUST NOT be used with any Solar Boost water heater. Rinnai water controllers brought in from other countries are not compatible with Rinnai appliances sold in Australia. Regardless of water controller installation, all Rinnai water heaters must only be installed by an Authorised person.
WATER CONTROLLER INSTALLATION Location NOTE • DO NOT install water controllers near a heat source, such as a cook top, stove or oven. Heat, steam, smoke and hot oil may cause damage. • DO NOT install water controllers outdoors unless protection from water / dust ingress and sunlight are provided. • The water controller set as the MASTER water controller MUST NOT be installed in a bathroom. • DO NOT install water controllers in direct sunlight.
WATER CONTROLLER INSTALLATION Communication Cable(s) & ’Ezi connect’ CAUTION DO NOT attempt to connect cables to the 'Ezi connect' cable connector at the water heater unless the electric power to the water heater is switched ‘off’ otherwise damage to electrical components may occur. If your water heater is not fitted with an 'Ezi connect' cable connector, installation must be completed by a qualified and licensed trades person. 1.
WATER CONTROLLER INSTALLATION Additional Programming & Activation Requirements ? QUESTION 1 Are there four water controllers connected? IF NO: You have three (or fewer) water controllers, go to Question 2. IF YES: You will need to activate the fourth water controller as follows: STEP 1: For the water controller in the KITCHEN ONLY, press and hold the ‘Priority Transfer’ and ‘On/Off’ buttons simultaneously (see Fig. 1) until a ‘beep’ is heard (approximately 5 seconds).
COMMISSIONING TESTING 1. Before final connection of the water heater purge gas, hot water and cold water supply lines. Debris or swarf in either the gas or water supplies may cause damage. 2. Turn on gas and cold water supplies. 3. Test for water leaks and gas escapes near the unit. 4. Isolate gas supply. Remove test point screw located on the gas inlet connection and attach pressure gauge. IMPORTANT Confirm the control board dipswitch settings are set to the correct positions as required , i.
COMMISSIONING GAS PRESSURE SETTING The regulator is electronically controlled and factory pre-set. Under normal circumstances it DOES NOT require adjustment during installation. Make adjustments ONLY if the unit is not operating correctly and all other possible causes for incorrect operation have been eliminated. Instructions for gas pressure setting are located in the instruction pocket inside the appliance front cover.
