REGULATORY INFORMATION
Your Rinnai Continuous Flow water heater complies with NZS5262. A declaration to this effect can be
found on the Energy Safety Service website; www.ess.govt.nz.
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.
All dimensions referred to in these instructions are in millimetres, unless otherwise specified.
Please keep this instruction booklet in a safe place for future reference.
WARNING ABOUT HOT WATER
Excessively hot water is dangerous, especially for young
children and the infirm. Rinnai Continuous Flow water
heaters allow you to control the temperature of hot water to
safe levels.
Water temperatures above 55°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 New Zealand ) can
severely burn a child in less than half a second. At 55°C it
takes half a minute.
ALWAYS......
Test the temperature of the water with your elbow before
placing 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 tightly.
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 55°C
(Contact Rinnai New Zealand).
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.

FEATURES AND BENEFITS
Congratulations on purchasing the latest technology temperature controlled Rinnai continuous flow
water heating system.
• The Rinnai Infinity and Infinity HD 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 microprocessor 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 Infinity, HD and Efficiency24 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.
• '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 XR26 Plus, XR20 Plus, Infinity HD250, HD250i, HD200
and HD200i models only.

The anti frost protection system operates
automatically as required whenever the appliance is
connected to the electric power supply.
If the appliance is not going to be used for an
extended period and it is desired that the electric
power supply is disconnected, turn off the water and
gas supplies and arrange for your plumber to drain all
water from the appliance to prevent frost damage.

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 temperatures
to a maximum of 50°C will be stored in the
system memory at all times whilst mains power
remains connected.

Kitchen
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.

GENERAL WATER CONTROL INFORMATION
Remote 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. 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:
Kitchen Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C* ( 60, 65, 75°C Infinity HD models only )
Bathroom Controller:
Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Bath fill Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48°C
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 save energy. To obtain water temperatures lower
than 37°C simply add cold water.
Water controllers are an optional extra. 'Universal', 'Deluxe', and ‘Wireless’ water controllers can be
fitted. Universal water controllers allow temperature selection only. Deluxe water controllers allow
temperature selection, shower saver / bath fill, voice prompting and have a clock function.
Water controllers allow the water temperature to be set from the various locations where they are
installed. The temperature selected will be available to all outlets.
Universal (MC-91-2A), Deluxe (MC/BC-70-2A and MC/BC-100V) and Wireless Water Controllers
- available configurations:
A maximum of 4 water controllers can be fitted. Any combination of deluxe, universal
and wireless controllers can be used with the following limitations:
Only ONE master controller can be installed. This can be a MC-70V/MC-100V, a
Wired and
Wireless
Installations
MC-91 (when programmed as a master controller) or a MC502S (wireless) water
controller.
Up to TWO BC-70V/BC-100V water controllers can be installed.

that are located directly below the 'Shower / Bath
temp.' buttons located behind the flip panel.
The selected volume is displayed at the bottom of the
controller monitor numerically, and graphically by the
long bar against the level markers.
When filling a bath for the first time, it is
recommended that a low bath fill volume such as 100
litres or lower be used. During any subsequent bath
fills the volume can then be adjusted to suit your
known bath volume and or desired fill level.
The long bar and the level markers are used to
graphically represent the current shower / bath
volume in litres. The examples to the right show
shower / bath volumes set to 60, 120 and 240 litres.
Remember that the bath level markers on the display are not a true
representation of your bath. i.e. the 'half-way' mark on the monitor is not
NOTE
necessarily the 'half-way' point on your bath.

APPLIANCE LOCATION
(External Models)
This appliance is designed for ‘Outdoor’ Installation only. As such, it must be located in an above
ground open air situation with natural ventilation, without stagnant areas, where gas leakage and
products of combustion are rapidly dispersed by wind and natural convection.
This appliance must be mounted on a vertical structure with the water and gas connections on the
underside pointing downwards. For appliances installed on elevated structures or under floors specific
requirements apply. Refer to NZS5261 for details.
This appliance must not be used as a domestic spa or swimming pool heater.
Location of the appliance flue terminal must be in accordance with NZS5261 Section 2.6.11, 2.6.12
and 2.6.13. Figure 3 is reproduced in the ‘Horizonal Flue Terminal Clearances’ section of these
instructions. Note that NZS5261-2003 was current at the time of printing but may have been
superseded. It is the installers’ responsibility to ensure current requirements are met.
(Internal Models)
This appliance is designed for ‘Indoor’ installation only. It may be installed ‘Outdoors’ in an enclosure
if the requirements of NZS5261 are satisfied. An enclosure is defined as a compartment, enclosed
area or partitioned off space primarily used for the installing of the appliance. If installed in an
enclosure, either Internally or Externally, the location should be ventilated to allow gas to dissipate
and provision must be made for the safe disposal of any leaking water to an exposed location.

the 'OFF' position.
NOTE
Rinnai New Zealand 19 Installation Manual
Page 22
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 where the distance between
the water heater and the outlets is considerable, a flow and return system can be used to minimize
the waiting time for hot water delivery. Alternatively, multiple appliances can be strategically placed to
serve outlets with minimal delay time. Contact Rinnai for further information.
An AC230V, 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 connections
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 undue 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.
PIPE SIZING
See Table 1 page 21 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 NZS5261 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 21 for applicable water pressures. Approved pressure limiting valves may be
required if the ‘Maximum’ rated water supply pressures in Table 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 55º 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.
MOUNTING THE APPLIANCE
See Table 1, page 21 for individual appliance weights. The wall or structure on which the units are to
be mounted must be capable of supporting these weights and the associated pipe-work.

CONDENSATE DRAIN (REU-K2430WG ONLY)
A
B
C
D
E
The Efficiency REU-K2430WG water heater generates condensate continuously at a rate of up to 5
litres per hour as a by-product of a 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
NOTE
considerations.
Water heater drain outlet connection, ½” (20mm) BSP male.

plastic fitting.
Drain pipe and fittings to match item .
B
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.

CONDENSATE DRAIN (REU-K2430WG ONLY)
(g) Where discharging over a tundish or gully trap, drain 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 25.
COMMON STACK DISCHARGE
Where individual water heaters are installed in a multistorey building, the condensate drain 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 25.
AREAS SUBJECT TO FREEZING
In areas where water pipes are prone 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.

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 turn 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 rate, in accordance with manufacturers
instructions.
8. With all gas appliances in operation at maximum gas rate, the pressure should read between
1.0 - 3.5 kPa on Natural Gas. On LPG the pressure should be 2.75 - 3.5 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 55º C cannot be selected on bathroom or ensuite controllers.
13. After testing is completed, explain to the householder the functions and operation of the water
heater and temperature controllers (if fitted). Ensure the 'Customer Record' on page 17 of this
manual is filled in and that the booklet is handed to the customer.
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.

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.
All boxes and covers are suitable for painting to blend in with the exterior of your home.
Pipe Cover:
Where a recess box is not used, pipe covers are recommended as the finishing touch to an Rinnai
continuous flow hot water heater installation. Basically the covers are 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 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 tamper proof
installation.
Flue Diverters
Designed to redirect flue products when the water heater is installed on a balcony, patio etc. this
product is available for selected models only.
