Selection Guide & Sizing
To ensure that the best Continuous Flow unit is installed in any application, we recommend breaking it down to 6 basic considerations:
1. How many Showers are there?
A single bathroom home with a single shower outlet will operate using the smaller 16 or 20 litre model, whereas with multiple
bathrooms or showers with 2 roses, then you may need to factor in the likelihood of simultaneous demand. In this case the larger
26 or 32 litre unit would be required.
2. What is the Geographical location?
Ambient water temperatures vary immensely throughout Australia. Please refer to the below map and table as a guideline only:
Climate
Number of Bathrooms
The number of shower oulets the unit can
supply is dependant on water pressure, ambient
water pressure and outlet water ow capacity.
(Based on 3 Star, 9L/min)
1 2 3
Warm 16 to 20 Litre 16 to 26 Litres 26 to 32 Litre
Cool 16 to 20 Litre 20 to 26 Litres 26 to 32 Litre
07
Hot Water Delivery Temperature
3. The type of shower roses installed?
Most States and Territories have legislation where new homes must have a minimum of 3 Star rated (9 litre/min) shower roses
installed. Many older homes however, still have higher ow rated showers.
HANDY
HINT
We recommend to replace shower roses with low ow rated (WELs approved) xtures
to assist with water conservation. Rinnai Continuous Flow models are more suited to
lower ow rates than any other units on the market.
4. Is there a large bath or spa?
If there is a large bath or spa that needs lling, then regardless of the number of bathrooms or showers, we’d recommend the
larger 26 or 32 litre.
5. Design of the house? (The distance to the furthest tap)
Where are the bathrooms and other ‘wet areas’ in relation to the hot water system? The further away the shower, the longer it takes
to get the hot water. Typically if the distance to an outlet is 15m or greater you could be looking at a time delay for the hot water of
approximately 10-15 seconds.
As a general rule, Rinnai recommend:
• Units are best installed closest to the Kitchen – but with consideration to Bathroom locations
• New homes could consider two smaller units if hot water is required at opposite ends of home
• For long hot water runs, install a Rinnai Smartstart pre-heat ow and return system
6. Is it an Internal or External Installation?
Most installations are external. This is by far the least expensive alternative with the unit readily accessible for servicing.
Alternatively Rinnai have internal units which can be placed inside the house, in a cupboard or even in the ceiling cavity.
All Rinnai internal units require a ue to be installed to atmosphere. For further details of the ueing requirements, please refer to
pages 9 to 11.
Hot Water Delivery Temperature
AS/NZS3500 regulates that the temperature allowed in areas used primarily for personal hygiene (Bathrooms, Ensuites and Powder
Rooms) must be limited to a maximum of 50°C in domestic installations. There are 2 ways to achieve this with Rinnai Continuous Flow
appliances:
1. Preset 55°C Appliances – The installing plumber supply’s and installs an approved Tempering Valve on the hot water branch
line to the bathrooms etc set at a maximum of 50°C. This then allows for the hotter 55°C water to be supplied to the kitchen &
laundry which is best for cutting greases and rinsing. Whilst this requires the additional expense of a Tempering Valve, it is
Rinnai’s preferred method of installation as it gives the end-user the best hot water solution.
2. Preset 50°C Appliances – This is where the unit is factory set to 50°C and the entire house is supplied at this temperature. This
is adequate in most domestic situations, but any temperature losses in the pipe work due to poor or old insulation can result in
lower temperatures being delivered at the outlet. This is usually noticeable in the kitchen when trying to wash dishes with (say)
46 or 47
o
C. Previously there was no way of overcoming this other than re-insulating supply lines.
Rinnai Preset 50
o
C – Now adjustable to give 50
o
C at the outlet
Recent amendments to AS3498 allows for the introduction of adjustable 50
o
C Preset appliances. Similar to Tempering
Valves, the installing plumber can now measure the temperature at the outlet with a thermometer and if necessary,
adjust the Rinnai Continuous Flow unit. This can be done in increments of 1
o
C to a maximum of 4
o
C. At the time of
printing the majority of Rinnai Preset 50 appliances already have this feature.
If unsure whether a particular appliance is adjustable, please call the Rinnai HelpLine on 1300 555 545 quoting
the serial number of the appliance.

Water Controllers
Water Controllers
Why install Water Controllers?
Rinnai strongly recommend installing Controllers to allow you to take full advantage of all the benets available. Water Controllers
depending on the model selected, enable the following additional benets with any Continuous Flow model with the exception
of Solar Boost units:
Maximum number of Water Controllers
A maximum of 4 Water Controllers can be tted to all Rinnai Continuous Flow water heaters. Any combination of Universal Wireless
or Wired or Deluxe Water Controllers can be used with the following provisions:
1. Only ONE Deluxe Master Water controller can be installed
2. Up to TWO Deluxe Bathroom Water Controllers
3. The FOURTH Water Controllers MUST BE a Universal Controller (Wired or Wireless)
HANDY
HINT
Water Controllers are great for unit servicing as they are also a diagnostic tool.
Should there be a problem with getting hot water, the Controllers will usually ash a
predetermined number advising of the fault. i.e. low gas supply.
All Controllers:
• Eliminate temperature uctuations if someone else turns on another tap
• Allow the user to pre-set safe temperatures
• Enable precise temperature control up to 50
o
C in the Bathrooms and
up to 55
O
C in the Kitchen
• Conserve water usually wasted juggling the hot & cold taps
• Installing 2 Controllers extend the Parts & Labour warranty of the Rinnai
INFINITY by 2 years to 5 years
• Activate the Rinnai Smartstart® pre-heat function (see page 16 for details)
• Install up to 4 Controllers (some limitations apply, see below)
Universal (Wired) Controllers
• Ideal for new homes and renovations where easy access to running wires
is appropriate

Internal Flueing
Internal Flueing
Rinnai oer the only 26 litre internal units available on the market. The Rinnai INFINITY 26i domestic unit and the HD200i commercial
model. Ideal for replacement of existing internal hot water systems or simply used when limited space is available externally in
applications such as apartments and townhouses. It is a room sealed appliance, drawing combustion air from the outside.
There are 4 ueing options that enable the installation of an internal Continuous Flow model virtually anywhere:
1. Vertical Direct Flueing - Straight up through the ceiling and penetrating the rooine
2. Horizontal Direct Flueing - 90º bend o top of unit, backwards through the wall
3.
Horizontal Extended Flueing - Identical to horizontal ueing but with additional components to extend the length of the ue
4.
Combination Flueing - Mixture of both horizontal and vertical ues
Flue Components
All Rinnai Internal Flue systems are made up from individual components. All components must be ordered separately.

Internal Flueing
Vertical Direct Flueing
This is the most common system sold with ueing
directly above the unit penetrating the roof line in a
single storey home.
The following components will be required in these
combination:
• Vertical Flue Terminal with roof cowl
• Additional Flue lengths (if required)
• Ceiling/Wall Ring (Cover plate)
Note: For vertical installations over 1.5m a condensate
drain trap is also required.
Combination Flueing
(Vertical and Horizontal)
(Multiple bends with a vertical or
horizontal ue termination)
The exibility of the various Rinnai
ueing components enables our
Continuous Flow internal models to
be installed virtually anywhere, using
a roof or wall terminal, extension
pieces (mounted vertically and
horizontally), bends, adaptors and
condensate traps as required.
11
Internal Flueing
Horizontal Direct Flueing
The second most common system where the Continuous Flow model is ued directly out through a back or side wall.
For this installation you will require the following components:
• 90° Bend & Starter
• Horizontal Flue Terminal (in desired lengths)
• External Wall plate
• Ceiling/Wall Ring (Cover plate
Horizontal Extension Flueing
This option is used when the water heater is mounted against an internal wall and ueing needs to extend horizontally to exit an
external wall. Rinnai ueing components must be used together with extension pieces and bends as required.
Important Flueing Rules
1. Installations can consist of both horizontal and vertical runs to a maximum length of 9 metres
2. Installations can have a maximum of three 90° bends.
3. For any installation over 1.5 metres in height, a condensate drain must be installed

Technical Information
Continuous Flow Technical Information
Flow Rate Characteristics
In response to market trends and as part of our continuous improvement processes, Rinnai have developed new technologies and
are introducing a number of modications that allow our continuous ow models to operate over a wider range of conditions.
Collectively known as “Enhanced Combustion Technology” (ECT) and in conjunction with new lower minimum gas rate and ow
rates, these improvements deliver tangible benets to our domestic continuous ow customers.
Our core Rinnai INFINITY Continuous Flow products now have the lowest minimum gas rates on the market. This means that at our
new lowest possible burner settings the following two enhanced features are realised:
a) They now operate at lower ow rates which makes them more compatible with 3 star (7.5-9.0 l/min) low ow water saving
xtures
b) They can now operate at far higher ambient incoming water temperatures. This is particularly of benet to the northern
States of Australia and some inland areas where the water temperature from the ground can be as high as 30
o
C
Many Rinnai Continuous Flow models have variable ow rates that can exceed the commonly known ow rate. i.e. a Rinnai INFINITY
20 can actually give a maximum ow rate of 24 litres per minutes with a temperature rise of only 20
o
C. Ambient water temperatures
vary immensely throughout Australia and often higher ow rates can be achieved with our models. This is most common when in
use with Water Controllers set at showering temperatures between 39 and 42
o
C.

Smartstart® Water Saver
The Rinnai Smartstart® water saver has been developed to specically reduce
water wastage whenever a hot tap is turned on.
• Allows user to pre-heat the water in the pipes before the tap is turned on
• Simply activated by the ‘preheat’ button on any Rinnai Water Controller
• Takes a minute or two to warm up depending on the size of the
installation
• Saves literally tens of thousands of litres of water over the life of the hot
water system
Plumbing is designed as a ‘ring-main’ or ow and return loop around the
house. In existing homes, a return line can be plumbed in from the furthest
point back to the Rinnai Continuous Flow unit.
Operation overview
The Smartstart® system heats the water in the pipework water connected
between the water heater and the hot water outlets before any outlets are
opened using the ‘ow and return’ pipework principle. This results in water
savings and reduced waiting time for heated water delivery from the outlet
when opened.
Traditional ‘ow and return’ systems usually keep the water in the pipework
heated continuously. The Smartstart® system however, only heats the water
before the outlet is opened. This results in signicant energy savings because
water is not heated unnecessarily whilst retaining the benets of traditional
ow and return systems.
The Smartstart® module is usually located below the Rinnai Continuous Flow
water heater, however, it can be mounted anywhere within the return loop.

Close Coupled Systems
Where the Storage Cylinder and the Solar Collectors (panels) are coupled
together and the installation is on the roof. A choice of an electric boost
element in the cylinder or a gas booster installed usually on the side of the
house completes the system.
Benets:
• Technically very ecient, economical to install and low maintenance
• No recirculating pumps and pipe runs – reducing heat losses and
improving running eciencies
• No electricity required to operate pumps to recirculate the water
through the panels
• Space saving in that it eliminates the need for a storage tank at ground
level – ideal for courtyard homes or small blocks
• Supplied standard in NEW Titanium colour
• Wide range of Colorbond® colours available. Ask your Rinnai Solar
consultant for selection
What is the Booster?
The booster is simply a backstop to make sure you always have hot water available, such as during cloudy or rainy weather or
during the winter months. It also operates should you exhaust the stored water on those occasions when an extra family stays for
a weekend!
If the majority of your hot water is used in the evening (i.e. for running baths &
spas etc) then re-heating will occur as follows depending on the type of booster:
Electric Boost – the thermostat will turn on the element overnight to bring the
water back to temperature. This means that if no hot water is used in the morning
the suns energy is wasted the next day as the water is already hot.
Gas Boost – the booster will not activate until the hot water is required. If that is
early morning then the gas booster will be required, but if later in the day, some
solar reheating will have occurred.
Regardless of whether your hot water is used in the mornings or evenings, gas
boosting is the most ecient, convenient and cost eective boost option.
Gas boosters operate only on demand and have the additional benet of
never running out of hot water
Rinnai Solar Hot Water Systems
Split Systems
Where the Storage Cylinder and the Solar Collectors are literally split and
installed separately. A choice of an electric boost element in the cylinder or
an in-line gas booster which can be installed on the side of the cylinder, or
remote mounted on a wall.
Benets:
• Easy installation on roofs
• Streamlined appearance - minimal impact on the aesthetics of your
roof line with only the Collectors visible
• Split Systems do not require reinforcement of the roof structure, as the
weight associated with water storage is at ground level
• Split System cylinder can be installed internally or externally
• Collectors and the tank do not need to be installed at the same time
– ideal during construction of new homes and major renovations

Solar Rebates
How to claim the RECs rebate?
Ultimately the RECs awarded to any system are traded/sold on the open market at a price which uctuates according to supply and
demand.The simplest way is to ll out the REC rebate declaration form that is supplied with each system which transfers the RECs
to Rinnai. In return we will pay you the market rate which is current at that time less a small admin fee. Alternatively, you can
speculate on the market value and sell them at a later stage either to us or another authorised trader.
Additional Rebates/Incentives
From time to time both the Federal and State Governments as well as some local councils oer rebates (additional to RECs) as an
incentive to install Solar Hot Water systems. These are often conditional and must always be checked before purchase.
Conditions for additional rebates sometimes include:
• Conversions from Electric Systems to Solar Systems
• Gas Boosted systems only
• Regional/Rural areas only
• Means testing on household income
• Concession Card holders
• Minimum RECs contribution (i.e. minimum 20 RECs)
• Residency restrictions
• Domestic applications only
Government Rebates
The Australian Greenhouse Oce awards Renewable Energy Certicates (RECs) according to how much energy each Rinnai Solar
system saves compared with a conventional electric water heater. The Federal Government legislation states that RECs are
applicable when a solar system is installed in a new home or replaces an existing hot water system.
Solar Zones
The number of RECs awarded to a particular Rinnai Solar System varies according to the amount of energy saved relative to an
electric water heater installed in the same location. This is inuenced by the amount of local solar gain and the local operating
conditions. Darwin, for example, has more solar gain than Hobart, hence a particular system installed in Darwin will be assigned a
higher number of RECs than if it were installed in Hobart. For the purposes of REC assessment, Australia is divided into 4 solar zones
as shown in the map.

How much can I get?
As can be seen from the above table, Rinnai Solar Systems are typically awarded between 20 to 42 RECs. Each REC has a $ value
that uctuates according to market demand, which needs to be checked at the time of purchase. If a REC was valued at (say)
$40, your rebate for Rinnai systems would be anywhere between $800 and $1680.
At the time of printing this brochure, the Federal Government is also oering an additional $1600 to switch from an electric
system to Solar. In some States there are additional rebates on top of this again!
RECs and Rinnai Solar Systems
The following tables show the awarded RECs for a selection of the most popular systems that Rinnai sell. If your particular system is
not shown, please ask you Rinnai Solar specialist who can further advise.
Standard Rinnai Systems are calculated with the following Collectors:
• Rinnai Prestige Excelsior & Excelsior (FTC) Collectors
• Rinnai Sunmaster Enduro & Equinox (FTC) Collectors

Sizing
Correct Sizing
Correct Sizing is vital for optimum performance
Number of Occupants
The number of users in any installation is extremely important as it directly aects the size of unit that is required. Nobody likes a
cold shower so it is vital that any system is correctly sized for an application. Please talk to your Rinnai Hot Water Specialist about
the best model to suit your needs.
Below we have outlined some of the considerations for various Rinnai Solar Systems:
Tips on selecting the best Rinnai System
To correctly select a Rinnai Solar System for a home, a number of lifestyle factors need to be considered.
1. What Solar Zone is applicable for the installation?
This determines the amount of solar energy that will be available and can inuence the number of collectors
that should be installed.
2. Is Gas available?
Natural Gas boosting is the cheapest to run and the most environmentally friendly form of boosting for a Solar
System. Rinnai recommends that gas boosting should always be the rst choice if available. Alternatively, both
LPG & Electric boosting are also economical to run with correctly sized systems.
3. Is there limited space available?
This can determine whether space is available at ground level for a Split System storage cylinder. If limited,
then a Close Coupled roof mounted system would be the most appropriate.
4. Is the area prone to frost or sub-zero temperatures?
Frost protection should always be used if temperatures fall below zero. This can be achieved by using
Frost Tolerant Collectors (FTCs) which must be requested at the time of ordering. FTC panels are warranted
to -6ºC under certain conditions. Please ask you Rinnai Solar Specialist for further details or see on-line at
www.rinnai.com.au
Gas Boosted Solar
• Sizing parameter – Number of bedrooms in the home
• The storage cylinder capacity determines the available solar
heated hot water
• The Gas Booster is always available as a backup, therefore hot
water will never run out
• Undersized system could mean the system is relying on the gas
booster more often – increasing running costs
• Insucient Solar Collectors would also reduce the solar gain
causing reliance on the gas booster
Electric Boosted Solar
• Sizing Parameter – Number of Bedrooms in the home
• The Storage Cylinder size determines the amount of hot water
available regardless of whether solar generated or electric
boosted
• Hot water can run out if not correctly sized
• Choice of electricity tari aects availability of re-heated water:
- Normal (peak) tari continually re-heats
- O-peak will generally not re-heat until overnight

For Cyclone prone areas it is often mandatory but in any event, it is highly
recommended to use a cyclone frame. These have a dierent conguration to the
standard frames and are made in much stronger materials.
Reverse & Side Pitch Installations
In addition to the above frames, you can also order Reverse & Side Pitch adaptor kits

Mains Pressure Systems
Rinnai has two mains pressure ranges of Electric Hot Water – Centurion & HOTFLO. They are simply a storage cylinder that holds
water at a pre-set temperature with the use of thermostatic control. As hot water is used, it is replaced with cold water and reheats
again. Hot Water delivery is at mains pressure or the maximum allowable pressure should the home have a pressure limiting device
installed.
Rinnai Centurion
Rinnai centurion electric tanks are made from high quality stainless steel, they have positive
domes on both ends of the cylinder, for optimum capacity in a slim line water heater. All
centurion water heaters come standard with a hot water return connection point, which is
ideal for ow and return plumbing or solar conversions at a later date.
• Superior quality long life Stainless Steel tank with a 10 year warranty
• No requirement for a sacricial anode – reduced maintenance
• Taller slimline tank. With positive domes at both ends for optimum capacity
and neater appearance
• Solar compatible - added exibility at a later stage
• Connection for pumped return line
• Colorbond® outer case - durable and weather resistant
• Flexibility - suitable for internal and external use
• Thermostatically controlled with safety temperature shut o for added safety and
peace of mind
• Left handed connections - suits most common installations
Colorbond® is a registered trademark of BlueScope Steel Limited.
Rinnai HOTFLO
Our quality HOTFLO range of electric tanks are available in various storage capacities
ranging from a compact 40 Litre right up to the large 315 Litre model. We also have a
complete range of element sizes minimising changeover costs.
• Economical Vitreous Enamel lined steel tank with a 5 year warranty
• Inbuilt anode protection - extends the life of the tank
• Dual handed - allows increased exibility of installation
• Flexibility - suitable for internal and external use
• Foam Insulation exceeds MEPS* (Minimum Energy Performance Standard)
by an average of 20%, reducing heat loss and running costs
• Thermostatically controlled with safety temperature shut o for added safety
and peace of mind
* Excludes 40 litre
Gravity Feed Systems
Similar to normal storage cylinders the gravity feed systems again hold water at a pre-set temperature but this time not under
mains pressure. Sometimes also referred to as ‘constant pressure’ systems, the Roofmaster is usually located in the roof space.
Whereas mains pressure systems usually operate between 300 – 500kPa, a gravity feed system operates at the ‘head of pressure’
dependant on how high the tank is above the tap/shower. In single storey installations this is generally about 20 to 24kPa.
Rinnai Roofmaster
The Rinnai gravity feed Roofmaster water heaters are concealed in your roof space. The
storage cylinder is made from heavy duty copper which makes it extremely reliable and
corrosion resistant. The lower pressure at which they operate puts much less stress on
the cylinder and ttings, so everything lasts that much longer.
• Copper cylinder construction - reliable and corrosion resistant
with a 7 year warranty
• Specically designed for in-roof Installations
• Gravity feed, less stress on components means longer life
• Thermostatically controlled with silent operation
• Flexibility to integrate with solar and/or combustion stove (wetback) installations
• Operates at the ‘head of pressure’ 20 to 24 kPa

The recovery times for all storage tanks is based on 3 factors:
1. The volume of water
2. The size of the electric element
3. The set temperature
The table below shows all available Rinnai sizes and assumes that the unit is wired for immediate reheat i.e. peak tari. For
O-peak wired units, the table can only be used as a guide for how long it will take from the point that re-heating occurs.
Element size Litres per hour heated by 50ºC
1.2kW element heats 20.6 litres
2.4kW element heats 41.2 litres
3.6kW element heats 61.9 litres
4.8kW element heats 82.5 litres

A Rinnai Manifold Pack consists of 2 to 6 Heavy Duty continuous
ow water heaters plumbed together to allow higher ow rates
than a single unit can provide.
The Rinnai Heavy Duty (HD) water heaters are suitable for single
installation, Manifold Pack or Demand Duo installations. Each
Commercial application require dierent quantities of hot water,
therefore if you are unsure on the sizing guidelines, please contact
our National Commercial Project Division on 1300 555 545 for
assistance.

Commercial
Rinnai Demand Duo Systems
Rinnai Demand Duo is the combination of between 1 to 6 gas
Continuous Flow water heaters with single or multiple storage
cylinders. The storage cylinder allows a short period of high hot
water ow rate, greater than the continuous ow rate of the HD
water heater(s). i.e ‘peak demand’ applications such as:
• Hotels & Motels
• Apartment Blocks
• Student Accommodation
• Shower Blocks
• Commercial Kitchens
• Commercial Laundries
Rinnai Commercial Solar Systems
Rinnai Commercial Solar hot water systems provide solar pre-heated
water to the Rinnai Commercial gas hot water systems such as the
Manifold Pack or Demand Duo system. The system is selected
according to the daily hot water demand for the application, the
required solar contribution, and what solar zone the system is
located in.
For further information or on site assistance please contact our
National Commercial Project Division on 1300 555 545.
