General information
Frost protection
Frost protection is fitted as standard on
all models. Frost protection operates
automatically, as required, whenever the
appliance is connected to power.
If the power has failed and there is a risk of
damage from frost, turn off the gas supply to
the unit and open a tap to allow flow through
the unit, this may prevent damage from
freezing.
If the INFINITY is not going to be used for a
period and the power supply is disconnected,
turn off the water and gas supplies, and
arrange for a plumber to drain the water to
prevent frost damage. If for practical reasons a
plumber is unable to drain the INFINITY, there
is an instruction on p.10.
Installation by a licensed tradesperson
Only a licensed tradesperson can install,
adjust, maintain, and service this water heater.
Any work carried out by a non-licensed
tradesperson is illegal and will void any
warranty.
Safety devices
The Rinnai INFINITY has the following safety
devices fitted:
•
flame failure
•
boil-dry protection
•
overheat protection (OHS)

Discolouration of flue outlets
The colour of the flue outlet
may change over time due
to condensate in the exhaust
gases. This is normal. The
discolouration will not damage
the unit and will not affect the
performance of the water heater.
Environmental
The Rinnai INFINITY is
manufactured from a number of
recyclable materials. At the end
of its useful life please consider
what parts could be recycled, for
example scrap metal, PCB etc.
Servicing
Rinnai has a maintenance, service and spare
parts network with personnel who are fully
trained and equipped to give the best advice on
your Rinnai appliance.
Servicing and repair should only be carried out
by authorised personnel, please call Rinnai
(0800 746 624).
For reliable operation Rinnai INFINITY water
heaters in residential applications should be
serviced every two years*.
Regular maintenance and servicing is not
covered by the Rinnai warranty. Do not attempt
to carry out any service work other than that
mentioned in this guide. If you have any other
faults or problems, please contact your installer
or Rinnai.
* Including the flue system if you have an internal unit
* Installations located in or near coastal areas may require
additional maintenance due to corrosive airborne ocean salt
INFINITY controllers
Temperature controllers are available
to allow precise digital temperature
control
—
a great safety feature if you
have young children. Controllers can
be fitted at any time during or after
installation of the Rinnai INFINITY.
Solar installations
There is a recommended solar layout for
continuous flow water heaters used in solar
installations. It is important your installer
configures your solar system correctly as water
heaters in solar installations produce higher
than normal temperatures.
INFINITY controllers cannot be used with
Rinnai continuous flow water heaters in solar
installations as the hot water does not always
pass through the unit.
The A-Series range of water heaters are not
suitable for solar installations as they cannot be
set to 75
°
C.
