Leaders in continuous flow
When you turn on a tap you want water at the right temperature fast, which is
why over the years we’ve devoted considerable time and resource to leading
edge research and development.
We were the first to introduce continuous flow technology and have been tirelessly working on
improving this ever since. Our commitment to bring you the latest technology has resulted in
the next generation of water heaters.

What is continuous flow?
A continuous flow gas hot water system only heats water when it passes through the
unit. It will deliver a continuous flow of heated water at a predetermined flow rate,
depending on the model, as long as the unit is connected to the power supply.
General principle of operation
Each Rinnai INFINITY has a number of components that control the accuracy of water
temperature and water flow. These components are:
•
•
•
•
•
PCB (the onboard computer)
water control valve
water flow sensor
modulating gas valve
outlet water temperature sensor
The unit senses the need to start when water begins to flow through the appliance (when a tap is
turned on). The combustion fan starts, ignition begins (electronic requiring electricity), and the
gas valve opens. Once the flame is established the appliance will heat the water as required until
the tap is turned off.
How gas continuous flow works

Condensing technology utilises a secondary latent heat exchanger to increase the thermal
efficiency of the unit (95% vs. 80%). Incoming cold water passes through the latent heat
exchanger first where heat is extracted from the exhaust gas (which would otherwise be
wasted), which preheats the water by approximately 5 °C before going to the primary heat
exchanger.

Model selection for residential applications
When specifying residential hot water applications there are some basic
questions that you need to ask in order to correctly design a system. You also
need to bear in mind the future requirements of the building. The key point
is water heating solutions should be designed to the number of hot water
outlets and not the number of people.
Which model?
Questions to ask to
determine which model(s)
may be suitable.
the Rinnai INFINITY closer to
the kitchen sink where there
is an immediate demand for
hot water.
• How many bathrooms?
If bathrooms are situated at
opposite ends of the house
two Rinnai INFINITY units
may be required.
• Where are the bathrooms
and other hot water outlets
positioned in the house?
• How often will the
hot water outlets run
simultaneously?
• What type of tapware is
installed?
• What is the location of the
property in New Zealand?
How many bathrooms?
A VT16 or VT20 unit may be
suitable for a one bathroom
home, whereas a two or three
bathroom home will need a
larger Rinnai INFINITY, or even
multiple units.
Where are the bathrooms
and other hot water outlets
positioned in the house?
Where are the bathrooms
and other hot water outlets in
relation to where the Rinnai
INFINITY is to be installed? In
most cases it is better to site
How often will the
hot water outlets run
simultaneously?
How likely will hot water
outlets, such as showers, be
used at the same time.
Scenario one: Two bathroom
home with a couple who
rarely use the second
shower—a VT20 may be
suitable.
Scenario two: Two bathroom
home with a family of five
who fight for two showers in
the morning—a larger Rinnai
INFINITY would be needed.
What type of tapware is
installed?
There is a large range of
tapware in the market, some
with very high flow rates. The
main consideration is the
type of shower rose installed
and how many litres it puts
out—typical flow rates for
showers is around 8-10 L/min.
This needs to factored when
determining the required
Rinnai INFINITY model.
To measure the flow rate
of a shower, hold a bucket
under the shower rose for
one minute and measure the
volume of water.
Location of the property in
New Zealand?
Ambient water temperatures
will vary throughout the
country, for example, the
South Island in winter will be
much colder than the North
Island. This is important when
determining the incoming
water temperature and the
temperature rise required at
the hot water outlet as this
will affect the output of the
unit. For more information
refer appendix 1 on p. 40.
Use the New Zealand map on
the next page to determine
the location of the property
in relation to the climate
zone.
Budget, size of house, number of hot water outlets, and hot water requirements all factor
in determining the right continuous flow hot water system for your home. Use the product
selector table on the next page to work our which model is right for you.

1. Determine the hot water outlets that will run simultaneously in your house, and list the flow rates
against them.

* You can check your own actual water flow rates by holding a bucket under the hot water outlet for a minute and
measuring the volume.
** A number of washing machines, particularly front loaders, have a cold-only connection as they have an internal
heater. Hot water in this instance, as it isn’t required, would not need to be factored into the calculation.
2. Total the maximum simultaneous water flow, e.g. 24 litres.
3. In the column for geographical region move down until a number bigger than your total appears.

Location of Rinnai INFINITY units
To provide safe and effective water heating it is important to adhere to all
relevant gas installation standards. Check the guidelines detailed in this guide.
If in any doubt it pays to consult a licensed gasfitter to double check where the
unit can be located.
General installation
considerations
The Rinnai INFINITY should be
placed as close as possible to
the most frequently used hot
water outlet(s) to minimise
the delay for hot water. In
most cases it is better to site
the Rinnai INFINITY closer to
the kitchen where there is an
immediate demand for hot
water.
For installations where
the distance between the
water heater and outlets is
considerable, a flow and return
system with a buffer tank, can
be used to minimise the waiting
time for hot water delivery.
Alternatively multiple units can
be strategically placed to serve
different outlets.
Operating noise
Some people are susceptible to
low level noise. Rinnai INFINITY
units operate at 49 dB(A).
This needs to be considered if
locating the appliance near a
bedroom.
Easy access
All continuous flow water
heaters must be installed to
ensure access can be gained
for servicing and repair,
without hazard or undue
difficulty.
If mounting appliances at
height the owner must arrange
permanent and safe access,
or provide another means of
access such as scissor or boom
lifts.
External models
External models are designed
for outdoor installations only.
They must be located above
ground where the products
of combustion can be
naturally dispersed. They
should not be in enclosed
areas as the unit can be
choked by its own flue gases,
which will cause the unit
to malfunction. Refer to
the general flue clearances
diagram on the next page.
Internal models
Internal models are designed
for indoor installations only.
External models must be
mounted on a vertical structure
with the water and gas
connections on the underside
pointing downwards.
They are a flued appliance—
flue components purchased
separately. They may be
installed in an enclosure if the
requirements of AS/NZS 5601.1
are satisfied. An enclosure is
defined as a compartment,
enclosed area or partitioned
off space primarily used
for the installation of the
appliance.
For internal units we
recommend a 600 mm
clearance for servicing
access. This can be reduced
to 50 mm if installed in
a cupboard, refer to the
general access clearances
diagram on the next page.
Internal models must be mounted
on a vertical structure with the
water and gas connections on the
underside pointing downwards.

To ensure products of combustion are cleared,
adequate clearance from the building is
required.
The flue cowl should have a 500 mm clearance
from any part of the building. This also applies
to steeped and pitched roofs, which should be
clear of the ridge line.
Lesser clearances may provide perfectly

Rinnai INFINITY digital controllers
With a Rinnai INFINITY digital controller you choose your own personalised settings. Just select
the water temperature you want (37-55 °C) in up to four different locations. This means you can
set water at a safe temperature in the bathroom (a great safety feature), then set it higher, if you
wish, in the kitchen and laundry.
Additional benefits
• Reduces temperature fluctuation when other taps are used in the house.
• Receive an extended warranty, Rinnai INFINITY units installed with digital controllers receive
an extra two years warranty.
• View and troubleshoot any problems by using the controller as a diagnostic tool, for example
error code 11 when there is no gas.
Location
Water controllers are water resistant, however, durability is improved when positioned outside
the shower recess. In other areas they must be installed at least 400 mm above the highest part
of the sink, basin, or bath.
Maximum number of controllers
For residential applications a maximum of four controllers can be fitted, please note important
points regarding controller combinations below.
• Only ONE master controller can be installed, this can be a Kitchen Deluxe, Compact, or
Wireless Controller.
• Up to TWO Bathroom Deluxe Controllers can be installed.
• The fourth controller in any installation must be a Compact or Wireless Controller.
Each controller can be individually programmed, however the water heater can only deliver one
set temperature at any time. For example, John is in the shower and has set the controller to
42 °C, Jane uses the kitchen tap at the same time—the water temperature coming out of the
kitchen tap will also be 42 °C (or lower if using a mixer and adding cold water). Jane can only
change the programmed temperature once John is out of the shower.
Wired controller cables
All wired controllers come with 15 m of cable. Additional cable can be ordered:
• R1069
• R1369
Please note
Additional cable for the Compact and Bathroom Deluxe controllers
Additional cable for the Kitchen Deluxe controller
Rinnai controllers cannot be used with Rinnai INFINITY units connected to a
solar system, or when a Rinnai iHeat is installed as the preset dip switch setting
on the Rinnai INFINITY needs to be adjusted from 55 °C to 75 °C.

Rinnai INFINITY upwards flue diverter
Description
The Rinnai INFINITY upwards flue diverter is an accessory
that can be fitted to an external Rinnai INFINITY water heater.
It is designed to expel combustion products in an upwards
direction.
The flue diverter is fitted with screws to the flue terminal of the
water heater.
Construction: Stainless steel
Specific applications
Noise reduction, in particular with the larger Rinnai INFINITY
models, where the unit is positioned close to a neighbouring
property.
Where there may be an obstruction such as a tree, fence,
wall, or other structure, that even though the Rinnai INFINITY
is installed with the required clearances, will perform more
efficiently if the flue gases are expelled upwards and away from
the obstruction.
Where there are multiple units installed that are positioned
facing each other—there is the potential for the units to
suffocate from the flue gases of the unit directly opposite.
With an upwards flue diverter the flue gases can be expelled
upwards and away from the units.

Rinnai INFINITY manifolding
Description
Rinnai INFINITY units can be manifolded together, in banks of
five (up to 25 individual units), by connecting them together in
parallel to enable a greater hot water flow rate than is possible
with a single unit.
A manifold electronic control system links each Rinnai
INFINITY unit in the system and will turn on each unit as
required. The system is designed to ensure gas is not wasted
and that an endless supply of hot water is always available.
Codes
REUMSB REUMSBMB REUMSBC1 REUMSBC2 (int. master)
(ext. master)
(slave)
( joiner )
Suitability
• VT24 and VT26 models (in residential applications)
• All HD models
• All EF models
Please note:
• Rinnai do not specify manifolded systems for smaller VT units
• For commercial applications use HD or EF250 models
How it works
A master (located internally or externally) and subcommunication PCB is installed in the first unit, other units only
have the sub-communication PCB (slave cable) installed. The
master communication PCB receives information about flow rates
from the PCB of each unit and balances the load on each unit.
Random selection of the units required to supply the flow
demand means that all units share the workload evenly.
All information is transmitted via communication cables to the
slave units. The master control also has an inbuilt fault detection
system and will allocate a replacement unit should one fail.
Manifold components
• REUMSB
Internal (connection made inside the unit) master manifold
kit.
• REUMSBMB
External (connection made outside the unit) master manifold
kit.
• REUMSBC1
Manifold slave cable.
• REUMSBC2
Joiner for greater than five manifolded Rinnai INFINITY units.
Refer appendix 3 ‘Manifolding components what to use where’
to determine manifolding components required.

Appendix 1
Water flow and gas usage
When calculating the model of the Rinnai INFINITY required it is important
to determine what the incoming water temperature will be. This is usually
calculated on the worst case scenario (winter). For example:
• Northland and Aucklanduse 15 °C
• Bay of Plenty, Gisborne, and Hawke’s Bay
use 10 °C
• Waikato, Taranaki, Wanganui, Manawatu, Wairarapa,
use 5 °C
Wellington, and South Island
Degree rise
In the specification pages for the Rinnai INFINITY water heating range we express a parameter
called ‘Nominal water capacity’. This means that at a 25 °C rise, the unit will produce a certain
number of litres per minute of hot water. For example:
• The VT26 external will produce 26 litres per minute at a 25 °C rise
• The VT24 external will produce 24 litres per minute at a 25 °C rise
Using the example above, for incoming water of 10 °C and a required temperature rise of 55 ° C,
the VT26 external will produce 14.4 litres per minute at a 45 °C rise (55-10), and the VT24 external
will produce 13.3 litres per minute at a 45 °C rise.
Water flow and gas usage tables
Use these tables to calculate model performance based on the incoming water temperature,
and the required outlet temperature.

Appendix 2
Rinnai INFINITY inbuilt frost protection
Frost protection is fitted as standard on all Rinnai INFINITY models. Frost
protection operates automatically, as required, whenever the appliance is
connected to the electric power supply.
How frost protection works
When the temperature inside the unit drops below 3.5 °C the frost protection turns on, providing
approximately 15 W of heat via electricity. Once the temperature inside the unit reaches 7 °C the
frost protection switches itself off.
The heat, provided by strategically placed ceramic heating elements, stops the water from
freezing within the pipework of the unit.
As frost protection requires electricity to run it is important that the unit is connected to the
power supply at all times. If left off in an area prone to frost Rinnai recommend draining the
appliance to prevent frost damage (not covered by warranty).

Appendix 6
LPG gas bottle consumption and cylinder clearances
LPG gas bottle consumption
Overview of LPG cylinder clearances
We often get asked about how long a gas bottle
will last when running a gas appliance. Using
the calculation below you can work this out
yourself.
LPG gas bottle energy calculation
1 kg of LPG gas contains 50.4 MJ of energy. This
means that a 45 kg LPG has bottle has 45 kg x
50.4 MJ = 2268 MJ. This calculation works for
different gas bottle sizes, here are the most
common:
• 9 kg
= 453.6 MJ
• 45 kg
= 2268 MJ
• twin pack = 4536 MJ (two 45 kg gas bottles)
B
A
C
D
Calculating how long an LPG bottle will last
To work out how many hours an LPG bottle will
last you need to divide the energy (MJ) of the
gas bottle by the total MJ input of the appliance.
A Min. clearance to a door
1m
B Min. clearance to an openable window
150 mm
For example
A household has a VT26 installed which runs
approximately 20 minutes a day, three five
minute showers and intermittent use of vanity
and kitchen taps (approx. five minutes).
D Min. clearance to a drain
• 2268 ÷ 199 MJ/h (maximum input of unit)
= 11.40 hours (running at full capacity)
• 11.40 hours x 60 minutes = 684 minutes
• 684 minutes ÷ 20 minutes (use per day)
= 34.2 days (approx. one 45 kg per month)
The above example is based on the unit
operating at a maximum flow rate and MJ/h
input (26 L/min and 199 MJ/h). In the real-world
this won’t be the case as the flow rate and gas
consumption when using vanity and kitchen
taps is much lower (2.4 L/min and 13 MJ/h), so in
reality the gas bottle will last a little longer.
Please note: This doesn’t factor other gas
appliances in the house.
For more information you can search the
internet (how long will a 45 kg gas bottle last)
as there are additional resources and blogs
available.

The above diagram is a modified version of a
drawing originally produced by ongas
(www.ongas.co.nz). It is intended to provide an
overview of the general clearances required for
LPG cylinders.
For detailed information relating to LPG cylinder
placement it is advisable to consult a licensed
gasfitter, your nearest LPG cylinder supplier, or
consult AS/NZS 5601.1 Gas Installations.
Appendix 7
Gas boosted solar
Rinnai INFINITY models can be easily plumbed to provide additional heat to a
solar hot water system to heat water when the solar hot water is not available.
How a gas boosted system works
1. The sun’s rays heat water in the solar
panels.
2. Hot water from the panels is stored
in the tank.
3. If the water is too cold, the Rinnai
INFINITY gas boost heats the water
on demand as it travels from the tank
to the tap.

The size of the Rinnai INFINITY depends
on the number of bathrooms, select
the Rinnai INFINITY model as if solar hot
water was not available.
