WARNING ABOUT HOT WATER
Heated water can be dangerous, especially for young
children and the infirm.
Water temperatures above 50°C can cause severe burns
instantly and may even result in death.
Those most at risk are children, disabled, elderly and the
infirm.
Hot water at 65°C (a very common hot water temperature in
Australia) can severely burn a child in less than half a second.
At 50°C it takes five minutes.
ALWAYS......
Test the temperature of the water with your elbow before plac ing your child in the bath, also
carefully feel water before bathing or showering yourself.
Supervise children whenever they are in the bathroom.
Make sure that the hot water tap is turned off tigh tl y.
CONSIDER.....
Installing child proof tap covers or child resistant taps (both approaches will prevent a small
hand being able to turn on the tap).
Setting your appliance at a maximum temperature of 50°C (Contact Rinnai Australia).
NEVER…..
Leave a toddler in the care of another child. They may not understand the need to have the
water temperature set at a safe level.
Rinnai Australia 1 Operation Manual
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 g as supplies are co nnected, hot water is availabl e whenever hot water tap s 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 infirm may be using the hot
water.
• The Rinnai Continuous Flow water heater products are power flued appliances. This makes them
COMPACT, saving both floor 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.
• The "Smartstart®" system when fitted can pre-heat the water in the pipework between the water
heater and the hot water outlets. This results in water savings and reduces waiting time for heated
water at the outlets.
• 'Deluxe' or 'Universal' Water Controllers are available as an optional extra. Depending on the
models chosen, these offer the following features:
• Bath fill function (Deluxe Bathroom Control Only).
• Voice Prompting (Deluxe Control Only).
• Clock (Deluxe Control Only).
• Up to four water controllers can be fitted. See page 6 for details.
• Water controller cables are connected easily by the end user using a convenient quick connect
system.
• Operating NOISE LEVEL IS VERY LOW.
• ERROR MESSAGES ARE DISPLAYED on the Water Controllers and Status Monitor*, assisting
with service. *Status Monitor available on INFINITY 26 Plus (REU-VRM2630WD), HD250e (REUVRM3237WC), HD200e (REU-VRM2632WC) and HD200i (REU-VRM2632FFUC) models only.

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.
Always check water temperature carefully before
use. Refer to the WARNING ABOUT HOT WATER
on "page 1" of this manual for important safety
information.
Do Not touch the unit cover or the flue outlet.
Do Not insert objects into the flue outlet.
On colder days steam may discharged from the flue
outlet. This condition is normal for high efficiency
appliances and does not indicate a fault.
At low water flows, the hot water unit may extingu ish
without warning. Opening the tap further will restart
the appliance.
Keep flammable materials, spray cans, fuel
containers, pool chemicals, trees, shrubs, etc. well
clear of the flue outlet.
Do Not spray water directly into the flue terminal.
If freezing conditions are expected, turn off water and
gas and drain all water from the appl iance. If power
and the automatic frost protection are connected,
freezing will be prevented. (Anti-frost protection is
fitted as standard equipment on External units and is
available as an optional extra on Internal Units)
The delivered water temperature is controlled
automatically. The flow may vary depending on the
delivery temperature selected and the ambient water
temperature.

Do Not use solvents!
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.
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.
There is no need to turn the water controller(s)
off after use. However, if you prefer to turn the
water controller(s) off, selected temp eratures
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 Controller's
temperature is set above 50°C, transferring
and then returning 'priority' to the Kitchen
Controller will result in a default set
temperature of 50°C being selected. This is a
safety feature.

Whilst hot water outlets are open the set temperature may be lowered. However the set temperature
cannot then be raised above 43°C. In addition, transfer of 'priority' between water controllers is not
possible. These are safety features.
Suggested temperatures are:
Kitchen 50°C ~ 55°C* Shower 37°C ~ 43°C, Bath fill 39°C ~ 45°C
* Temperature may not be available on all installations. Rinnai water heaters can be programmed to deliver higher temperatures
via the kitchen water controller. Contact Rinnai for more details.
These temperatures are suggestions only. You may find higher or lower temperatures more
comfortable. Maintaining lower temperatures helps sa ve ener gy. To o btain wa ter tem peratures lo wer
than 37°C simply add cold water.
Water controllers are an optional extra. 'Universal' and 'Deluxe' water controllers can be fitted.
Universal water controllers allow temperature selection only. Deluxe water controllers allow
temperature selection, shower saver / bath fill and have a clock function.

NOTE
ABOUT THE SMARTSTART® PREHEAT SYSTEM
Preheat Function
The “Preheat” function works in conjunction with various Rinnai water heater models and the
separately installed and optional Rinnai “Smartstart®” module.
When the “Preheat” function is activated and used in accordance with these in structions, 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.
The “Preheat” function is activated as follows:
1. Ensure that the hot water unit is on (temperature digits are displayed in the digital monitor ).
If more than one controller is fitted pre ss the ‘Transfer’ button to pass on priority to your
desired controller, the ‘Controller On’ indicator will illuminate to confirm that priority has been
assigned to this controller and that the hot water unit is ready to deliver hot water.
2. Select the desired temperature using the 'Temperature' buttons until the required
temperature is displayed in the digital monitor .
3. Press the ‘Preheat’ button once. The ‘Preheat’ indicator and the ‘In Use’ indicators
will illuminate, signifying that the preheat system has been activated.
4. Wait approximately two minutes before opening an outlet. This will allow the water in the
pipework to be warmed.
The waiting time may be longer or shorter than two minutes depending on your
particular installation configuration.
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 sho rt time and will not affect the
other functions of the water controller or water heater.
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 /Off' button twice.
Other Controller Functions
Controller functions such as temperature control and transfer of priority between multiple controllers
is not affected by the operation of the preheat. Such functions are described in the applicable sections
of this manual.

GENERAL INSTALLATION INSTRUCTIONS
(All Models)
This appliance must be placed as close as practicable to the most frequently used hot water outlet or
outlets to minimise the delay time for hot water delivery. For installations wher e the distance between
the water heater and the outlets is considerable, a flow and return system or the Rinnai Smartstart®
system can be used which minimise the waiting time for hot water delivery. Alternatively, multiple
appliances can be strategically placed to serve outlets with minimal delay t ime. Contact Rinnai for
further information.
An AC240V, 10 Amp, earthed power point must be provided adjacent to the appliance. For outdoor
installations this power point must be weather proof. It must be clear of the gas and water connection s
to the appliance and also the flue exhaust and water pressure relief valve. The power cord of the
appliance is 1.5 Metres long.
All appliances must be installed to ensure access can be gained without hazard or un due difficulty for
inspection, repair, renewal or operational purposes. Sufficient clearances shall allow access to, and
removal of, all serviceable components. Appliances should not be mounted higher than 3.5 metres
above the ground or floor level unless the customer can arrange permanent and safe access or can
provide another means of access, for example, by means of scissor or boom lifts acceptable to local
authorities.
PIPE SIZING
See Table 1 page 23 for appliance gas consumption. If the gas pipe sizing is insufficient the customer
will not get the full performance benefit. Gas pipe sizing must consider the gas input to this appliance
as well as all the other gas appliances in the premises. The gas meter and regulator must be specified
for this gas rate. An approved sizing chart such as the one in AS5601 should be used.
Water pipe sizing and layout should be performed in accordance with AS/NZS3500. All hot water pipework should be insulated to optimise performance and energy efficiency.
WATER SUPPLY
See Table 1, page 23 for applicable water pressures. Approved pressure limiting valves may be
required if the ‘Maximum’ rated water supply pressures in Ta ble 1 are exceeded. To achieve the rated
flow, the ‘Minimum’ water supply pressures in Table 1 must be supplied. The water heaters will
operate at lower pressures but will not achieve the rated flow. Contact Rinnai for ‘gravity fed’ or ‘low
pressure’ installations.
Water chemistry and impurity limits are detailed under ‘Warranty Conditions’. Most metropolitan water
supplies fall within the requirements. If you are unsure about your local water quality, contact your
water authority. If sludge or foreign matter is present in the water supply, a suitable filter or strainer
should be incorporated in the water supply to the water heater.
HOT WATER DELIVERY TEMPERATURE
Local regulations and or the requirements of AS/NZS 3500.4 must be considered 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 50º C or less. To ensure these regulations and
or requirements are met the system MUST be installed in accordance with the 'Water Heater and
Controller Installation Configurations' Section of these instructions.
WATER HEATER AND CONTROLLER INSTALLATION CONFIGURATIONS
If the appliance is marked to state that it delivers water not exceeding 50°C, local regulations may
permit it's installation without a Temperature Limiting Device. Installations without a Temperature
Limiting Device are shown in Diagram 1 (page 23). If you are unsure about your local regulations
contact your regulating authority or Rinnai.
If the appliance is NOT marked to state that it delivers water not exceeding 50°C, or your local

HORIZONTAL FLUE TERMINAL CLEARANCES (Extract from AS5601 - 2004)
HORIZONTAL OBSTRUCTIONS
AS5601-2004 ‘Gas Installations’ stipulates a minimum
horizontal clearance of 500 mm between a building
structure and obstruction facing the terminal. For Rinnai
external continuous flow water heaters such a building
structure must ‘obstruct’ th e full front cover height of the
appliance, or extend vertically above and below the front
cover. 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 INSTALLATIONS OF EXTERNAL MODELS
Dimension ‘h’ above does not apply when multiple Rinnai
external water heaters of the same model are installed on
the same vertical face with flue terminals at the same
height. Under these conditions appliances can abut each
other as shown. The total gas consumption of all
appliances applies when determining other clearances.

COAXIAL FLUEING FOR INTERNAL MODELS
Rinnai internal models described in this manual must use the coaxial Rinnai FF flue components. The
use of non Rinnai FF flue components may result in a dangerous situation and violates regulations.
The FF flue system must be installed in accordance with the ‘FF Flue Installation Manual’ which is
provided with the FF flue terminal components FFWALLTERM or FFROOFCOWL.
Installations can consist of both
horizontal and vertical runs to a
maximum length of 9 metres and
with a maximum of three 90°
bends.
If flue length exceeds 1.5m,
dipswitch 1 of SW1 is to be
switched to the 'OFF' position.
This increases the combustion
speed to overcome the additional
friction loses.
Basic methods of installation
There are four basic flue
installation methods available.
These are:
(1.) Direct Horizontal
(2.) Extended Horizontal
(3.) Vertical
(4.) Combination Vertical /
Horizontal
Multiple Terminal Installations
The terminal clearances stated in
AS5601 do not apply to the Rinnai
internal continuous flow water
heaters when they are installed
side by side.
AGA certification allows for a
horizontal separation of 160 mm
for roof terminals and 270 mm for
wall terminals.

E
The INFINITY ENVIRO 32 (REU-KM323 7WD) and INFINITY ENVIRO 26 (REU-KM263 5WD) 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. Instead, Rinnai recommend
plastic pipes and fittings such as Unplasticised Polyvinyl Chloride (UPVC) or Polyethylene (PE) which
is commonly used for irrigation piping.
IMPORTANT CONSIDERATIONS FOR THE CONDENSATE DRAIN PIPE
The content of AS3500.4:2003 Section 5.12 ‘Temperature / Pressure Relief and
Expansion Control Valve Drain Lines’ has been used as a guide in preparing these
considerations.
Water heater drain outlet connection, ½” (20mm) BSP male.
PE ½” BSP (20mm) female to barbed irrigation system connector (13 – 19mm) or equivalent
plastic fitting.
Drain pipe and fittings to match item .
Continuous fall (of at least 2°) from water heater to discharge point. Lengths and bends in
accordance with ‘LENGTH AND CHANGES OF DIRECTION’ below.
Suitable points of discharge are deemed to be drains, sewers or pits. DO NOT discharge onto
electrical connections, earth stakes, copper pipes, concrete paths or into a pond.
LENGTH AND CHANGES OF DIRECTION
Maximum length and changes of direction
greater than 45 ° should be as follows:
Max changes of direction >45° 3 4 5 6
Lengths and changes of direction
Max length (Metres) 9 8 7 6
INSTALLATION
(a) The drain line MUST NOT discharge onto electrical connections, earth stakes, copper pipes,
concrete paths or into a pond.
(b) The point of discharge from each drain line shall be located so that the release of condensate
does not cause a nuisance, is readily discernible and incurs no risk of damage to the building.
In view of (a) and (b), suitable points of discharge are deemed to be drains, sewers or pits.
(c) There shall be no tap, valve or other restrictions in any line.
(d) Each line shall fall continuously from the valve to the approved point of discharge.
(e) Drain lines shall not discharge into a storage water heater safe tray.
(f) The end of the condensate drain line shall be:
(i) not lower than 200 mm or higher than 300 mm above an unpaved surface; or
(ii) not lower than 75 mm or higher than 300 mm above a gravel pit not less than 100 mm in
diameter in a paved surface.
Rinnai Australia 27 Installation Manual
CONDENSATE DRAIN (REU-KM’ MODELS ONLY)
(g) Where disch arging over a tu ndish or gully trap, dra in lines shall have an air gap of a size at least
twice the diameter of the drain line.
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 27.
COMMON STACK DISCHARGE
Where individual water heaters are installed in a multistorey building, th e condensate dr ain lines may
discharge into a common stack, subject to the following:
(a) The discharge from the common stack is to a tundish, having a discharge line, that is not less
than the size of the common stack, directly connected to a fixture trap, and installed in connection
with any adjacent soil or waste stack.
(b) The discharge point of the common stack is such that any discharge is readily visible and not
cause any nuisance.
(c) The common stack is vented by extending the pipe upwards, above the roof level.
TUNDISH DRAIN LINES
The drain line from any tundish shall be not less than DN 20 or less than one size larger than that of
the largest drain line discharging into the tundish. Tundish drain lines shall comply with the
‘INSTALLATION’ requirements on page 27.
AREAS SUBJECT TO FREEZING
In areas where water pipes are p rone to freezing, the drain pipe from any valve shall be insulated and
not exceed 300 mm in length. It shall discharge into a tundish through an air gap of not less than 75
mm and not more than 150 mm measured from the outlet of the drain pipe to the rim of the tundish.

NOTE
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 6 to confirm the maximum number and combination of water controllers that can be fitted.
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.
POSITIONING OF WATER CONTROLLERS
Water controllers must be installed in shaded and clean locations. They should be fitted out of reach
of children (suggested height from floor to be at least 1500 mm). BC-100V remote controllers are
water resistant, however, durability is improved when positioned outside the shower recess. All deluxe
remote controllers must be installed at least 400 mm above the highest part of a sink, basin or bath.
• Do not install remote 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 remote controllers in direct sunlight.
• The MC-100V remote controller MUST NOT be installed in a bathroom.
• Do not install remote controllers outdoors unless protection from dust
ingress and sunlight are provided.
• Do not install remote controllers against a metal wall unless the wall is
earthed in accordance with AS/NZS3000.
• Water controllers MUST NOT be installed where chemicals such as benzine,
alcohol, turpentine or other similar chemicals are in use.
POSITIONING CONSIDERATIONS FOR THE MC-100V WATER CONTROLLER.
The MC-100V uses a Liquid Crystal Display (LCD) for the digital
monitor. Light reflections can make the LCD difficult to see at
direct eye level.
For best results when Installing the MC-100V mount the remote
controller lower than your eye-level to avoid these light
reflections.

CONNECTING COMMUNICATION CABLES TO THE WATER HEATER
Communication cables connect the water heater to water controllers and operate at an extra low
voltage (12 Volts DC) which is supp lied from the water heater . Communication cables ar e supplied
with the water controllers (15m) and are fitted with spade ter minals for co nnection to water heater . Up
to two cables can be connected directly to the ‘Ezi connect’ cable connector at the water heater.
Extension cables are available from Rinnai. Alternatively, two core sheathed (double insulated) flex
with minimum cross sectional area of 0.5mm² may be used. Cable length s must not exceed 20 metres.
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.
To connect up to two cables to the 'Ezi connect' cable connector
1. Isolate the electric power supply by switching the power point off and removing the power plug of
the water heater from the electric power socket.
2. Remove the retaining screw of the 'Ezi connect' cable connector at the base of the appliance.
3. Swing the 'Ezi connect' cable conn ector door op en an d thread the cab le th rough the weathe r seal
of the cable access hole in the direction shown allowing sufficient cable length so that the
sheath of the cable can be secured with cable clamp supplied with the transceiver.
4. Loosen screw terminals and and connect the cable spade connectors to these terminals
and re-tighten. Polarity is not important, either wire colour can be connected to either terminal.
5. Return the 'Ezi connect' cable connector to the original position taking care not to damage cable
wires in the process and replace the retaining screw .
Connecting Three or Four Controllers
Repeat steps 1, 2 and 3 above.
To connect three or four cables, separate all the cabl es to be fitted into
pairs. Cut off the existing spade connectors from each pair and reterminate each pair into a new spade connector (available from your
local electrical component retailer) so that there are only two sets
of spade connectors (4 spade connectors in total) to be terminated.
Repeat steps 4 and 5 above.

COMMISSIONING
TESTING
1. Before final connection of the water heater purge gas, hot water and cold water supply lines.
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.
5. Turn the power 'on' at the power point socket and tu rn on gas.
6. If water controllers are fitted, turn ensure they are controller 'ON', select the maximum delivery
temperature and open ALL available hot water taps including the shower. If remote controllers
are not fitted, simply open all available hot water taps. (CAUTION: Ensure building occupants do
not have access to hot water outlets during this procedure.)
7. Operate ALL other gas appliances at their maximum gas r ate, in accordance with manufactur ers
instructions.
8. With all gas appliances in operation at maximum gas rate, the pressure should read between
1.13 - 3.0 kPa on Natural Gas. On LPG the pressure sh ould be 2 .75 - 3.0 kPa. If the pressure is
lower, the gas supply is inadequate and the appliance will not operate to specification. It is the
Installers responsibility to check the gas meter, service regulator and pipe work for correct
operation/sizing and rectify as required. Note that the gas regulator on the appliance is
electronically controlled and factory pre-set. Under normal circumstances it DOES NOT need
adjustment during installation.
9. Close hot water taps including the shower.
10. Inspect and clean the strainer located on the cold water inlet connection. This procedure may
need to be repeated to ensure the strainer remains clear, especially on new installations.
11. If water controllers are fitted, it is necessary to test their operation through the complete range of
functions (refer to the Operation sections of this manual).
12. Confirm the hot water delivery temperature(s) using a thermometer. If controllers are fitted,
ensure temperatures exceeding 50º C cannot be selected on bathroom or ensuite contr ollers.
13. After testing is completed, explain to the householder the functions and operation of the water
heater and temperature controllers (if fitted). Ensure the “PRODUCT RECORDS” on page 35 of
this manual is filled in and that the booklet is handed to the customer. Reminding the customer
to complete the Warranty Card and forward to Rinna i.
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 to be found in the instruction pocket located inside the
appliance front cover.
COMMISSIONING CHECK LIST
A commissioning check list is provided to enable the installer to step through the correct
commissioning procedure when installing a Rinnai Continuous Flow water heater.
The check list can also assist the installer to identify potential installation errors that may prevent the

ACCESSORIES
Recess Box:
When installing an Rinnai Continuous Flow hot water heater in a new home or renovation, it is a great
idea to allow for a recess box to be included at the construction stage. These boxes allow you to
literally recess the appliance into the cavity of the wall saving precious space. In addition they virtually
hide your hot water system altogether. A semi recessed (approx. 70mm proud of the wall) model is
available for all water heater models. In additio n, a fully recessed (flush to the wall) model is available
for use with the INFINITY 32 and HD250e water hea ters. All boxes and covers are suitable for painting
to blend in with the exterior of your home.
Pipe Cover:
Pipe covers are recommended as the finishing touch to an Rinnai Continuous Flow hot water heater
installation. Basically the covers ar e designed to hide the plumbing pipework and valves. These are
particularly popular in installations where the unit is permanently visible to the occupants of the house.
The cover can be easily attached to the appliance and two pipe covers can be joined together for
longer pipework if necessary.
Security Cage:
The Rinnai cage is available t o protect the unit from theft and da m ag e if th e Rinn a i Co n tin uo us F low
hot water heater is located in an exposed area.
Security Bracket:
Prevent theft by securing your Rinnai Continuous Flow hot water heater with our custom security
bracket, easily installed it covers the lower mounting bracket of the appliance to create a ta mper proof
installation.
Rinnai Smartstart® Water Saver
How much water is wasted everyday in Australian households waiting for the shower to get hot?
