WARNING

WARNING ABOUT HOT WATER

Hot water can cause scalding. Those most

at risk are children and disabled, elderly and

inrm persons. (65°C water can severely

burn a child in half a second).

Rinnai have water heater models which

limit the delivery temperature to 50°C which

signicantly reduces the scald hazard.

Temperature limiting devices may also be

able to be tted. Contact Rinnai for further

information.

ALWAYS test the water temperature before

use, such as when lling a bath or basin or

entering a shower, to ensure it is suitable

for the application and will not cause scald

injury.

ALWAYS supervise children whenever

they are in the bathroom or near other

sources of hot water. Ensure any hot water

taps are closed rmly after use.

WARNINGS & IMPORTANT INFORMATION

Rinnai 5 HW_HD_CF OIM

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.

To clean your water controller(s) use a soft damp cloth

with a mild detergent.

DO NOT use solvents!

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.

Depending on the weather conditions and the length

of the pipe between the hot water unit and the

outlet in use, there may be a variation between the

temperatures displayed at the water controller(s) and

the temperature of the water at the outlet.

There is no need to turn the water controller(s) o󰀨

after use. However, if you prefer to turn the water

controller(s) o󰀨, your selected temperatures to a

maximum of 50°C will be stored in the system memory

at all times whilst mains power remains connected.

As a safety precaution, if a Kitchen Water Controller's

temperature is set above 50°C, transferring and then

returning 'priority' to the Kitchen Water Controller

will result in a default set temperature of 50°C being

selected. This is a safety feature.

DO NOT push the On/O󰀨 button on any Water

Controller when the water heater ‘In Use’ indicator is

illuminated as this will turn o󰀨 the water heater causing

the water to go cold. Someone maybe in the middle of

having a shower or lling a bath.

WARNINGS & IMPORTANT INFORMATION

Rinnai 7 HW_HD_CF OIM

FEATURES & BENEFITS

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

heater system.

• 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 three 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.

• A high altitude setting is built into the programming, and can be enabled, for those installation applications

sited from 610 to 2000 metres above sea level such as Alpine regions.

WARNINGS & IMPORTANT INFORMATION

Rinnai 8 HW_HD_CF OIM

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.

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 30. 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. 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

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_HD_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.

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)**

Master (MC) 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55*, 60*, 65*, 75*

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

NOTE

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.

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 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.

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

temperature is available to outlets.

Universal and Wireless 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 CONFIGURATIONS

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 THREE optional 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).

IMPORTANT

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 maximum of an additional TWO further water controllers can be tted, these can be deluxe bathroom,

universal or wireless water controllers.

To nd out more about the full range of Rinnai water controller models, contact Rinnai or visit: www.rinnai.com.au.

UNIVERSAL WATER CONTROLLER (MC-601Q) OPERATION

Turning On

If the water controller is switched o󰀨 (No digits displayed in the digital monitor window)

press the On/O󰀨 button once. The ON indicator will illuminate, indicating that the hot

water unit will be ready to supply hot water once a hot water tap is opened.

Adjusting Temperature

Select the desired temperature using the Hot water temp or buttons until the

required temperature is displayed on the digital monitor.

To operate the hot water unit, open any hot water tap. This will automatically light the

burner providing hot water. The water heater ‘In Use’ indicator will illuminate on the

water controller(s).

Once the hot water is running, if the set temperature is either too hot or cold press the

Hot water temp or buttons until the desired temperature is reached.

NOTE

Whilst hot water outlets are open, the set temperature may be lowered to a minimum of 37°C. For

safety, it cannot then be raised above 43°C until all hot water taps are closed.

If the water heater is turned ‘O󰀨’ whilst hot water taps are open it can not be turned back ‘On’ until

all hot water taps have been closed.

Temperatures higher than 50ºC MUST NOT be able to be selected on controllers installed in

bathrooms, ensuites or toilets. This is to help reduce the risk of burns from hot water. If this is not

the case, the controllers have been incorrectly installed. CONTACT YOUR INSTALLER.

The 'beep' sound can be muted by pressing the and buttons simultaneously for more than

3 seconds. To cancel sound muting, simply repeat the process.

CAUTION

Always check outlet water temperature before use. The parent / carer MUST check the temperature

before placing dependants in contact with hot water, see "Warning About Hot Water" on page 4.

Transferring Priority

To control the water delivery temperatures when using two or more water controllers it is

necessary to have priority transferred to the water controller you wish to use. Transferring

of priority will NOT be possible if the ‘In Use’ indicator is currently illuminated, as this

indicates hot water is owing and that another water controller already has priority.

An illuminated Priority indicator conrms that the desired water controller is in control

of the water delivery temperature. If the Priority indicator is not illuminated press the

Priority Transfer button once. The Priority indicator will illuminate, indicating that hot

water temperature control has been transferred and that the hot water unit will be ready

to supply hot water once a hot water tap is opened.

Water Controller Combinations & Congurations

Preheat Function

When the “Preheat” function is activated and used in accordance with these instructions, water in the pipework

connected between the water heater and the hot water outlets in your house is warmed before any outlets are

opened. This results in water savings and added convenience.

Preheat Operation

1. Ensure that the hot water unit is on (temperature digits are displayed in the digital monitor

3

). If more than

one water controller is tted press the ‘Priority Transfer’ button

8

to pass on priority to your desired water

controller. The ‘Controller Priority’ indicator

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.

NOTE

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 will go out.

This is to conserve energy. To reactivate, simply repeat steps 2-4 above.

* If the ‘Preheat’ button is pressed and the ‘Smartstart’ preheat unit is not installed, the ‘Preheat’

indicator will still light but there will be no preheat function. The ‘Preheat’ indicator 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.

NZS 5601 section 6. Wooden plugs shall not be used.

The top bracket has a keyhole slot so that the appliance

can be positioned by hanging it on one screw, once in

position the appliance can then be fully secured with

the application of further appropriate ttings.

The appliance can be mounted directly against the wall

or structure. There is no need to use, non combustible

sheeting or leave an air gap between the appliance

back panel and the wall or structure to meet the

temperature hazard requirements of AS/NZS 5601.

Service Connection Points

Refer to "Table 2. Supply, Flow rates, Weights & Service Connections" on page 30 for model specic connection

/ tting dimension details.

An Approved full ow isolation valve and disconnection union MUST BE tted 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 be tted to the appliance via a connection union.

If may be necessary to t a temperature limiting device for delivery to areas used primarily for the purposes of

personal hygiene. Refer to "Hot Water Delivery Temperature" on page 17.

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 gas 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 29, 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.

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.

Under these conditions appliances can abut each other as shown below.

The total gas consumption of all appliances applies when determining other clearances.

For appliance dimensions, refer to "Table 1. Appliance Dimensions" on page 29.
