FEATURES & BENEFITS

Congratulations on purchasing the latest technology temperature controlled Rinnai continuous ow 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� 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 Continuous Flow 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 off, no gas is used�

•

'Deluxe' or 'Universal' Water Controllers are available as an optional extra� Depending on the models chosen, these offer 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 B16,B20 & B26�

•

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

WARNINGS & IMPORTANT INFORMATION

Rinnai 8 HW_CF OIM

MAXIMUM DELIVERY TEMPERATURES

Rinnai 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�

NOTE

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 27� 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 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 owing through the appliance the burner will be ignited by electronic ignition. When the hot water tap is closed and water owing through the appliance has stopped the burner ame will extinguish.

RINNAI WATER CONTROLLERS

NOTE

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

Combinations & 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�

NOTE

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

Rinnai 9 HW_CF OIM

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�

Each water controller can be individually programmed, however the water heater can only deliver one set

temperature at any time. The available temperatures (°C) are as follows:

Water Controller

Temperatures (°C)**

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

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�

NOTE

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 will also go out� The burner will ignite again 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 Continuous Flow 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�

** 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�

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 ow 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.

IMPORTANT

There MUST be NO partial obstructions to the front cover of the appliance or any other parts of the appliance casing� This will avoid the appliance failing to operate under windy conditions�

Sideways Flue Diverter

When a Sideways Flue Diverter is to be tted the installer MUST also refer to the instructions provided with the Sideways Flue Diverter and observe all the specic clearances and warnings.

WARNING

CONTROL BOARD DIPSWITCH SETTING:

The installer MUST follow the Sideways Flue Diverter instructions of the "Commissioning Check List" provided on the front cover of the appliance and the "Commissioning Instructions" located in the inside the appliance front cover�

When delivered ex-factory ALL the switches of the control board dipswitch are set to OFF (left position)�

When a Sideways Flue Diverter is tted

the installer MUST set switches SW1 and SW3 to ON (right position) ONLY�

Improper setting of the switches will cause the appliance to operate incorrectly�

Multiple Appliance Installations

In reference to Horizontal Terminal Clearances (Extract

from AS/NZS 5601) dimension ‘h’ on page 18 does

not apply when multiple Rinnai external water heaters of the same model are installed on the same vertical

face with ue terminals at the same height.

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 controllers, transceivers and water heaters DO NOT contain user serviceable parts and must ONLY be serviced and repaired by an authorised person�

Master / Sub Water Controllers & Associated Temperatures

Only one MC model water controller can be designated as the 'Master' water controller� This water controller is

normally used in the kitchen and usually has a maximum temperature of 55°C, which is sufcient for almost all

kitchen applications� Temperatures higher than 55°C are possible but usually unnecessary and will result in higher gas use and increase the risk of burns�

Some additional conditions regarding Master Controller maximum temperatures apply when a wireless water controller is used as the 'Master' water controller�

(i) Temperatures of 55°C or higher can only be selected on the controller designated as the 'Master' water

controller if the transceiver 'Max Temp' is also programmed to 55°C or higher�

(ii) The temperature of hot water delivered is always limited to the maximum temperature programmed into the

water heater itself� For example, if the transceiver maximum temperature is programmed to 55°C and the water heater is limited to 50°C, the maximum temperature that the water heater will deliver is 50°C� In this case 55°C will be displayed on the wireless Master Controller until a tap is opened after which the display will revert to 50°C�

IMPORTANT

The water heater maximum temperature cannot be adjusted by the user� These adjustments can

ONLY be carried out by a qualied and licensed trades person.

The remaining water controllers are designated 'sub' controllers and are for use in bathrooms, toilets and laundries� The temperature limit for all 'Sub' controllers is always 50°C to minimise the risk of burns in these areas�

Adhesive labels are included for individual identication of wireless water controllers as master (Kitchen) or sub (Bathroom) water controllers. These labels are usually placed on the top back of the wireless water controller body.

Water Controllers Limitations

An installation can have up to 4 universal MC-601Q water controllers�

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 4 water controllers can be tted.

•

Only ONE master controller can be installed� This can be a deluxe kitchen, wireless or a universal (when

programmed as a master controller) water controller.

IMPORTANT

When a deluxe kitchen is tted it will always function as a master controller, this is the default

setting and can not be changed�

•

Up to TWO deluxe bathroom water controllers can be installed�

•

The FOURTH water controller in any installation MUST BE a wireless or a universal water controller�

For more information regarding deluxe kitchen, bathroom and wireless water controllers, contact Rinnai or visit: www�rinnai�com�au�

handed to the customer� Reminding the customer to complete the Warranty Card and forward to Rinnai�

DELIVERY TEMPERATURE

50°C Compliant Models

"50°C Compliant" appliances are factory set to deliver a maximum temperature not exceeding 50°C. For ne tuning they have an incremental adjustment mechanism that allows the installer to increase the appliance delivery temperature incrementally from the 'Factory Set’ value to temperatures slightly exceeding 50°C� This is intended to enable compensation for temperature losses in the pipe-work between the water heater and any outlets and

achieve the required temperature at the outlet. Instructions for incremental temperature adjustment are located in

the instruction pocket inside the appliance front cover�

For All Other Models

Rinnai 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 it is not this setting can be increased or decreased by the installer� Instructions for changing the maximum delivery temperature are located in the instruction pocket inside the appliance front cover�
