WARNINGS & IMPORTANT INFORMATION

FEATURES & BENEFITS

Congratulations on purchasing the latest technology temperature controlled Rinnai gas continuous ow water

heater.

The Rinnai gas continuous ow 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. This is particularly useful when the hot

water unit is installed where young children or the inrm may be using the hot water.

The Rinnai gas continuous ow water heater products are Fan-Assisted (power ued) appliances. This

•

makes them COMPACT, saving both oor and wall space.

The temperature of hot water is CONSTANTLY MONITORED by a BUILT-IN SENSOR. If the temperature

•

of the hot water rises to more than 3°C above the selected temperature the burner is turned OFF and only turned ON again when the temperature falls below the selected temperature.

The burner lights automatically when the hot water tap is opened, and goes out when the tap is closed.

•

IGNITION IS ELECTRONIC, so there is no pilot light. When the hot water tap is o󰀨, no gas is used.

'Deluxe' or 'Universal' Water Controllers are available as an optional extra. Depending on the models chosen,

•

these o󰀨er the following features:

Bath ll function (Deluxe Bathroom Control Only).

Voice Prompting (Deluxe Control Only).

Clock (Deluxe Control Only).

Up to four water controllers can be tted. See page 9 for details.

 For further information regarding Wireless and Deluxe water controllers please contact Rinnai or visit

www.rinnai.com.au.

The "Smartstart®" system when tted can pre-heat the water in the pipe-work between the water heater and

•

the hot water outlets. This results in water savings and reduces waiting time for heated water at the outlets.

Operating NOISE LEVEL IS VERY LOW.

•

ERROR MESSAGES ARE DISPLAYED on the Water Controllers and Status Monitor*, assisting with

•

service. *All models in the range covered by this manual have a “Status Monitor”, except Innity Enviro 16, Innity Enviro 26, B16,B20 & B26.

The Innity 26 Touch (REU-AM2626WDL) water heater model is supplied with one "MC-503" wireless

•

water controller kit that includes a transceiver and a wireless water controller, that is pre-programmed as a master controller. Additional "MC-503" wireless water controllers are available as an optional extra. Please refer the separate wireless operation manual for instructions on how to use the supplied wireless water controller.

NOTE

WATER TEMPERATURE CONTROL

MAXIMUM DELIVERY TEMPERATURES

Rinnai gas continuous ow 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.

This does not apply to “50 degree compliant” models. To meet the regulatory requirements the maximum delivery temperature is factory set and sealed.

For model specic information in regards to the factory pre-set temperature of your appliance

refer to "Table 3. Maximum Delivery Temperatures" on page 34. The appliance model number can be found on the dataplate, which is located on the left hand side of appliance.

OPERATION WITHOUT WATER CONTROLLERS

Rinnai gas continuous ow 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 owing through the appliance the burner will be ignited by electronic ignition and water will be delivered at the maximum temperature that the unit is capable of delivering. As with conventional water heaters cold water will need to added to reduce the temperature to the desired level. When the hot water tap is closed and water ceases to ow through the appliance, the burner ame will be extinguished.

Rinnai WATER CONTROLLERS

Other manufacturers water controllers are NOT compatible with Rinnai water heaters. Rinnai water controllers brought in from other countries are also NOT compatible with Rinnai appliances sold in Australia.

Water controllers MUST NOT be used with any Solar Boost water heater.

Water controllers are available as an optional extra. Wireless, Universal and Deluxe water controllers can be used together and will function as described in the Operation Sections of this manual. Refer to "Water Controller Congurations" on page 9 to conrm the maximum number and combination of water controllers that can be tted to your water heater model.

Location

Water controllers must be installed in shaded and clean locations. They should be tted out of reach of children (suggested height from oor to be at least 1500 mm).

Water Resistance

The MC-601Q universal water controller is a water resistant device, however excessive exposure to water such as immersion may result in damage to the water controller. Durability of water controllers is improved when positioned outside of the shower recess.

Controllers MUST BE installed at least 400 mm above the highest part of a sink, basin or bath.

DO NOT immerse the water controller into water.

AVOID direct exposure to water or steam as these conditions may cause a malfunction.

ALWAYS AVOID exposure to water when the battery compartment is open.

When cleaning your water controller use ONLY a damp cloth and a mild detergent.

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 ow 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. All the remaining water controllers are designated as ‘Sub’ water controllers and are for use in bathrooms, toilets and laundries. The maximum temperature limit for all ‘Sub’ water controllers is restricted to 50°C to minimise the risk of burns in these areas.

Any water controller that currently has priority is capable of setting the water temperature to be delivered, however the water heater can only assign 'priority' to one controller at a time and deliver the one set temperature. The available temperatures (°C) are as follows:

Water Controller

Temperatures (°C)**

Whilst hot water outlets are open ONLY the control used to set to delivery may be used to further adjust it. Transfer of 'priority' between controllers is NOT possible until all hot water taps have been closed. These are safety features.

For hygiene in sanitary areas such as bathrooms, the suggested temperature should be 37°C ~ 43°C.

The above is a suggestion only, as you may nd higher or lower temperatures more comfortable, however maintaining lower temperatures also helps to save energy.

To obtain water temperatures lower than 37°C, simply open the cold water tap and add cold water until the desired lower temperature is reached.

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 3°C above the selected temperature shown on the digital monitor or the pre-set limit when water controllers are not tted, the burner

will automatically go out. The ‘in use’ indicator once the outgoing hot water temperature falls to that shown on the digital monitor (or the pre-set limit of the appliance)

* Temperature may not be available on all installations. Some Rinnai gas continuous ow water

heaters can be programmed to deliver higher temperatures from the master water controller, or may be programmed to restrict the maximum available delivery temperature. Contact Rinnai for more details.

Master (MC) 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55*, 60*, 65*

Sub (MC or BC) 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50

will also go out. The burner will ignite again

** Temperature limiting devices (where tted) may further control what maximum delivery

temperature is available to outlets.

Universal and Wireless and water controllers allow temperature selection only. Deluxe water controllers allow temperature selection, have a clock function and the Deluxe Bathroom water controller has a shower saver / bath ll function is also available, contact Rinnai for further information regarding Wireless and Deluxe water controllers or visit www.rinnai.com.au.

Water Controller Congurations

Deluxe kitchen, bathroom and wireless water controllers are also available and various combinations of universal and the deluxe and wireless water controllers can be used with the following limitations:

A maximum of FOUR water controllers can be tted.

•

Only ONE master controller can be installed. This can be a deluxe kitchen (MC-100V), or any other MC

•

model water controller (when programmed to be a 'Master' controller).

When a deluxe kitchen (MC-100V) water controller is tted it will always function as a 'Master'

controller, this is the default setting and can NOT be changed.

A up to a maximum of TWO BC-100V water controllers can be installed.

•

The FOURTH water controller in any installation MUST BE a MC-601Q or a MC-503RC-S.

3. Press the "Preheat" button 1 once. The "Preheat" indicator 2 and the "In Use" indicator 7 will illuminate, signifying that the preheat system has been activated.

4. Wait for the "In Use" indicator 7 to go out (this may take 2 to 5 minutes). When this happens it signies that the water in the pipework has now been pre-warmed and is ready for delivery, and that a hot water tap can now be opened.

The waiting time may be longer or shorter depending on your particular installation conguration.

For best results always wait for the "In Use" indicator 7 to go out before opening a hot water tap.

The preheat function is cancelled 5 minutes after activation and the "Preheat" indicator 2 will go out. This is to conserve energy. To reactivate, simply repeat steps 2-4 above.

If the "Preheat" button 1 is pressed and the 'Smartstart' preheat unit is not installed, the "Preheat" indicator 2 will still light however there will be no preheat function. The "Preheat" indicator 2

will go out after a short time and will not a󰀨ect the other functions of the water controller or water

heater.

When deluxe Bathroom water controllers are tted, after using the Shower Saver / Bath Fill

function wait 30 seconds before activating the 'Preheat' function. Attempting to use the 'Preheat' function earlier will result in voice prompts being repeated until the system is reset. The system

can be reset by pressing the "On /O󰀨" button twice.

Water Controller Functions

Water controller functions such as temperature control and transfer of priority between multiple controllers are not

a󰀨ected by the operation of the preheat. Such functions are described in the applicable sections of this manual.
