General installation information
Securing the Rinnai INFINITY
The wall structure on which units are mounted
MUST BE capable of supporting the weight of
the appliance and associated pipe work.
Ensure that suitable xing screws or bolts
are used to secure the unit to the wall, in
accordance with AS/NZS 5601 section 6.
Wooden plugs shall not be used.
The top bracket has a keyhole slot so that the
appliance can be positioned by hanging it on
one screw. Once in position the appliance can
be secured with appropriate xings.
The appliance can be mounted directly against
the wall or structure. There is no need to use
non-combustible sheeting or leave an air gap
between the appliance back panel and the wall
or structure to meet the temperature hazard
requirements of AS/NZS 5601.
Pipe sizing
If the gas pipe sizing is insu󰀩cient the
appliance won’t perform properly. Gas pipe
sizing must consider the gas input into this
appliance as well as other gas appliances in
the premises. The gas meter and regulator
must be specied for this gas rate.
An approved sizing chart such as the one
in AS/NZS 5601 should be used. Refer
specication for gas consumption details.
Water pipe sizing and layout should be
performed in accordance with AS/NZS 3500.
All hot water pipe work should be insulated to
optimise performance and energy e󰀩ciency.
Water supply
The appliance is intended to be permanently
connected to the water mains.
Refer specication for operational water
pressure limitations. Approved pressure limiting
valves may be required if the maximum rated
water supply pressures are exceeded. To
achieve the rated ow, the minimum water
supply pressures must be met.
The water heaters will operate at lower
pressures but will not achieve the rated ow.
Contact Rinnai for gravity fed or low pressure
installations.
Water chemistry and impurity limits are detailed
in the operation guide within the warranty
section. Most metropolitan water supplies fall
within these requirements.
If you are unsure about the water quality
contact your water authority. If sludge or foreign
matter is present in the water supply, a suitable
lter or strainer is required in the water supply
to the water heater to prevent unwarranted
damage and loss of performance.
Frost protection
Frost protection operates automatically, as
long as the appliance is connected to the
electrical power supply, by activating when the
temperature inside the unit drops below
3.5 °C
1
, and turns o󰀨 once the temperature
inside the unit reaches 7 °C

Approximate temperatures
Frost protection thermistor
The EF26 and A-Series models have an
external thermistor to control frost protection. It
is a small black indicator located on the bottom
right hand side of the unit, directly underneath
the cover screw (circled below). The frost
protection thermistor needs to be exposed to
the outside air to correctly function—do not
insulate the frost protection circuit will not work
correctly.
