About your Rinnai iHeat
Congratulations on the purchase of your Rinnai iHeat combined water and heating system.
The Rinnai iHeat is a ducted home heating system that uses hot water from your Rinnai Infinity
continuous flow water heater to warm air and circulate it around your home.
Rinnai Infinity continuous flow installed—external or internal* models available
Rinnai iHeat installed in the ceiling space or under the floor
Ducting outlets—up to 12, each outlet provides approximately 1.8 kW
Rinnai thermostat controller provides multiple control options
Suitability
The Rinnai iHeat may be retrofitted to any home with an existing Rinnai Infinity continuous flow water heater, or
both units can be installed simultaneously.
The Rinnai iHeat can be installed in the ceiling space or under the floor. It must not be mounted in areas subject
to direct splashing—this is relevant to underfloor installations that could be exposed to water.
Specification summary
-- Power output
-- No. outlets
-- Heating area
-- Efficiency
-- Noise level of fan
= nominal 20 kW, maximum 25 kW (dependent on installation)
= up to 12 (each outlet provides approximately 1.8 kW)
= up to 250 m² (depending on where you live and how well insulated your house is)
= delivers heat at the same efficiency as the Rinnai Infinity
= sounds like an air conditioning unit
The Rinnai Infinity provides hot water to the iHeat air handler unit (heat exchanger). The heat exchanger extracts
the heat from the hot water and transfers it to a steady stream of air. This air is fed into the ducting system and is
distributed into each room. Water is returned to the Infinity for reheating.
The Rinnai iHeat is controlled via a wall thermostat which has three fan speed settings and can control up to four
different schedule periods per day.
* Ensure the Rinnai Infinity is positioned where overnight operation will not disturb occupants or neighbours.

Modes of operation
Ideally your installer will have
discussed your needs and
configured the thermostat to your
requirements, and spent some
time with you setting it up for the
first time.
During the cooler months there
will be two main modes of
operation.
1. System is in manual mode
(non-programmable mode)—
no timers are set and the
system is manually turned on
and off via the thermostat.
2. System is on heat with the
fan on auto—system runs on
timers, and is on all the time.
Location of the thermostat
The thermostat must be installed
approximately 1.5 m above the
floor on an internal wall and in the
location that requires heating. Do
not place in areas subject to:
---
draughts (hallways, regular
accessed doorways etc.)
--
Up and down
keys
Heat on
dead spots where the air does
not circulate freely (alcoves,
corners, behind doors etc.)
LCD screen: Important
The thermostat has an LCD screen.
Sharp instruments like a pen or
pencil can damage the thermostat.
Batteries
The thermostat comes
with two AA alkaline
batteries installed.
When the batteries are running
low a warning will display on the
main screen for approximately 30
days. It is recommended that you
replace the batteries once a year
to prevent leakage, and to prevent
the thermostat from shutting
down. Replace the batteries as
follows:
1. Remove the front of the
thermostat from the base
by pulling it straight out. All
programming is retained
during battery replacement.
2. Install two new AA alkaline
batteries.
3. Replace the thermostat back
on its base making sure the
terminal screw blocks align
with the pins on the back
of the thermostat. After
two minutes the device will
automatically return to the
main screen.

Care of your iHeat
Your iHeat system needs very little maintenance, however the following information will keep it
working efficiently.
Cleaning the return air filter
Your iHeat system has a large
return air grille through which air
is returned to the iHeat for
reheating. The return air grille
contains a filter that traps dust
and other particles from the air.
This needs to be cleaned regularly
(every 2-4 weeks). If this is not
done you may notice increased
noise at the return air grille.
To clean the return air filter:
1. Remove filter from return air
grille housing.
Cleaning the Rinnai Infinity
water filter
Cleaning the Infinity
water filter will reduce the
likelihood of blockages
to the water heater which
could cause insufficient
water flow to the iHeat.
It is recommended the water filter
is cleaned every year. This would
normally be completed by a Rinnai
Service Centre as part of annual
servicing, but could be needed
inbetween times if you experience
any problems with insufficient
water flow to the pump.
To avoid burns wait until
the water heater cools
before cleaning the water
filter as hot water may drain from
the unit if there has been recent
hot water use. Turn off the gas and
power to the Infinity.
WARNING
2. Clean any dust or debris from
both sides of the filter using
a vacuum cleaner, a soft dry
cloth, or a soft brush. Do this
on a flat surface to stop the
frame from bending out of
shape.
1. Unscrew the water filter from
the position marked in the
diagrams below.
3. If required, wipe down the
return air grille using a damp
cloth.
4. Return the filter to the return
air grille and secure the grille
in place.
2. Flush the filter using clean
water.
3. Replace the water filter.
4. Turn on the gas and power to
the unit.

Checking the LED lights
Viewing panel
You can check the LED lights through the narrow viewing panel on the control box lid. Do not remove the control
box lid as there is a risk of electric shock due to high voltage.
---
One or more green lights—you have power
Red flashing light—an error has occurred
Bleeding air from the system
Sometimes air can get trapped in the iHeat circuit which can affect the performance of the system. This can be
easily fixed by operating the easing gear on the pressure relief valve for approximately two minutes.
To avoid burns (water can come out of the unit at 75 °C), wait until the water heater cools as hot water may drain
from the unit if there has been recent hot water use. Turn off the gas and power to the Infinity.
The pressure relief valve of the iHeat is located in between the Rinnai Infinity piping (as shown below). To bleed air
from the system gently raise the easing gear and hold open for approximately two minutes. If air is in the system it
will come ‘sputtering’ out—just like air in your water pipes. To close gently lower the easing gear.
Lift and lower gently

General information
Before operation please read these instructions to get an overview of how to operate, maintain
and service your Rinnai iHeat system.
Electrical connection
The iHeat air handler
unit is supplied with
a 1.5 m power cord
and 3-pin plug. The
standard electrical
connection is to the side of the
unit. This must be plugged into an
earthed power point.
The electrical cord should not
come into contact with the air
handler unit. If the supply cord
is damaged, it must be replaced
by a licensed tradesperson. This
must be a genuine replacement
part available from Rinnai—part
number 12019.
Keeping the power on to the
iHeat on at all times
It is critical that power to the iHeat
unit is left on at all times. This is
required to enable the automatic
frost protection and biosafe
operations.
Biosafe operation
This operation occurs if the iHeat
has not been used in seven days
(i.e. during summer).
Power is required to run the
biosafe operation, which runs the
pump for two minutes every week
(after a week of inactivity) to kill
any bugs in the water.
Rinnai water controllers
If you have existing
Rinnai water
controllers these
will need to be
disconnected as
these will not work with the Rinnai
iHeat system. This is because the
preset temperature of your Rinnai
Infinity needs to be raised from 55
°C to ≥ 60 °C, to get sufficient heat
output for your central heating
system, and to operate the biosafe
operation.
The timing of this operation will
depend on when the unit was
connected to power. For example,
if this occurred at 4pm, the biosafe
operation will operate at 4pm.
Gas and/or electricity failure
during operation
If the power and/or gas is
disrupted during operation the
central heating system will stop
operating, but the thermostat
will still indicate the system is on
due to the battery backup. Once
the power and/or gas is restored
the system will return to normal
operation without you having to
do anything.
Frost protection
Frost protection is fitted
on your iHeat unit as
well as on all current
Rinnai Infinity VT, HD,
and EF models. Frost protection
operates automatically, as
required, whenever the appliance
is connected to the electric power
supply. For the iHeat unit, it will
activate when temperatures fall
below 2 °C, and for Rinnai Infinity
models (with frost protection),
when the temperature inside the
units falls below 3.5 °C.
If normal operation does
not resume refer to the
Troubleshooting section in this
guide.
If you experience a power cut in
the middle of the night the biosafe
operation will revert to the time
that the power was restored. If
this is a nuisance (due to noise),
disconnect the power to the iHeat
at a suitable time to reset the
biosafe operation.
gas supply to the Rinnai Infinity
unit and open a tap slightly to
allow water flow through the unit.
This may prevent damage from
freezing.
If the iHeat and Infinity are not
going to be used for an extended
period, and the electric power
supply is disconnected, turn off
the water and gas supplies and
arrange for your plumber to drain
all the water from the iHeat unit
and the Rinnai Infinity to prevent
frost damage. This is important
as frost damage is not covered by
warranty.
Typical modes of operation
The four common modes of iHeat
operation will be:
Cooler months
-- System is on heat with the fan
on auto—runs on timers and is
on all the time.
--
System is in manual mode—no
timers are set and the system
is manually turned on and off
via the thermostat.
Warmer months
-- Thermostat is set to ‘heat off’,
or
--
Thermostat is set to ‘heat
off’, but the fan is set to
continuously run on lo, med,
or hi to circulate air through
the house—this will need to
be done manually each time
(p. 9).
If power has failed and there is risk
of damage from frost, turn off the
iHeat Operation Guide: 12063-A 01-13 | 15
Installation checklist
The installer must complete an installation checklist, which is on the back of the commissioning
sheet supplied with the iHeat. They must also instruct you about the use and care of the
appliance, and ensure you understand the safety instructions and operation of the appliance.
Before the installer leaves ensure they leave the commissioning sheet with you. This is important
as it demonstrates they have installed the system in accordance with our instructions.

All Rinnai appliances must
be installed, commissioned,
serviced, repaired and removed
in accordance with the
manufacturer’s instructions, local
regulations, and municipal building
codes by persons authorised by
local regulations to do so.
All appliances must be operated
and maintained in accordance
with the manufacturer’s operating
instructions.
The warranty applies only to the
components supplied by Rinnai.
It does not apply to components
supplied by others, such as,
isolating valves, electrical switches,
pipe work, electrical cables, fuses,
and where applicable components
supplied by others, but not limited
to these.
Where the appliance has not
been sited in accordance with the
installation instructions or installed
such that normal service access is
difficult, a service charge will apply.
If at the discretion of the attending
service person the installation
is deemed illegal or access is
dangerous, service will be refused.
Any work required to gain access
to the appliance will be chargeable
by the attending service person
(for example, removal of walls, or
the use of special equipment to
move components, but not limited
to these).
Where a failed component is
replaced under warranty, the
balance of the original appliance
warranty will remain effective. The
replacement part or appliance
does not carry a new warranty.
Rinnai reserve the right to transfer
functional components from
defective appliances if they are
suitable.
Rinnai reserve the right to have the
installed product returned to the
factory for inspection.
Where the iHeat central heating
system is installed outside the
metropolitan area or further than
40 km from a Rinnai authorised
service centre, travel costs shall be
the owner’s responsibility.

Most metropolitan water supplies fall within these limits. If you are unsure about water quality, please contact
Rinnai and we will provide you with details of an authorised agency able to test your water for compliance to
Rinnai standards. If sludge or foreign matter is present in the water supply, a suitable filter should be incorporated
in the water supply. Some examples of water quality issues where water may need to be treated:
----
Hard water (areas including Wanganui)
Aggressive water (areas including Christchurch)
Both hard and aggressive water (some bore water)
Other continuous flow water heaters connected to the Rinnai iHeat
The Rinnai iHeat system has been designed and tested for optimum performance with a Rinnai Infinity continuous
flow water heater. Other continuous flow water heaters may also be suitable. Please check the suitability with the
manufacturer of the water heater before installation as this may affect your water heater warranty.
If a continuous flow water heater, other than a Rinnai Infinity, is installed with the Rinnai iHeat this will be deemed
as a component supplied by others and will not be covered by this warranty. This includes iHeat system faults
caused by a faulty continuous flow water heater other than a Rinnai Infinity.
Installation by trained installers only
The warranty only applies to systems installed by listed installers, installers who have completed the Rinnai iHeat
online specifying and installation courses. For listed installers please refer to the Rinnai website:
