Congratulations on purchasing the Technologically Advanced, Temperature Controlled,
Rinnai Hot Water System.
x Rinnai water heaters will NEVER RUN OUT of hot water. As long as electricity,
water, and gas supplies are connected, hot water is available when hot water taps are
open.
x Built into the main micro-processor is the facility to LIMIT THE MAXIMUM
TEMPERATURE of the hot water supplied. The water temperature may be set to
various temperatures. This is particularly useful when the hot water unit is installed
where young children or the infirm may be using the hot water. If required, the
temperature can be changed via the dip switches on the PCB or with a localised
controller. For further information, please contact Rinnai.
x Rinnai Infinity water heaters are powered flue appliances. This makes them
COMPACT, saving both floor and wall space.
x The temperature of outgoing hot water is CONSTANTLY MONITORED by a BUILT-
IN SENSOR. If the temperature of the outgoing hot water rises to more than 3°C
above the selected temperature the burner is shut OFF and only turned ON again
when the temperature falls to below the selected temperature.
x The burner lights automatically when the hot water tap is opened, and extinguishes
when the tap is closed. IGNITION IS ELECTRONIC, so there is no pilot light. When
the hot water tap is off, no gas is used.
x The Infinity Condensing 32i / HDC1500i and Condensing 32e / HDC1500e have a
built in Status Monitor on the front of the unit to display error codes and run
condition. Up to four external temperature controllers can be mounted remotely from
the heater. This offers the following additional features:
Localised temperature setting.
Diagnostic information.
Error Codes.
Clock
Bath fill
x ‘Deluxe’ Temperature Controllers are an optional extra. These provide functions
including Bath Fill, Voice Prompt, and Clock Setting.
x Temperatures selected at the controllers are retained in the SYSTEM MEMORY
x Operating NOISE LEVEL IS VERY LOW.
x ERROR MESSAGES ARE DISPLAYED on the Temperature Controllers, assisting
with service.
x FROST PROTECTION device built in as standard.
FEATURES AND BENEFITS

6
Excessively hot water is dangerous, especially for young children and the infirm. The
water heater allows you to control the temperature of your hot water to safe levels.
Do stay with children whenever
they are in the bathroom.
Do take them out of the bathroom if
you need to answer the phone or
door.
Do test the temperature of the water
with your elbow before placing your
child in the bath.
Do make sure that the tap is turned
off tightly.
Do consider setting your Rinnai
Water Heater at a maximum
temperature of 50°C.
Do install a child proof tap cover
OR,
Do install a child resistant tap.
Do not leave a toddler in the care of
another small child. The older child
may not have safely set the temperature.
IMPORTANT INFORMATION
Water temperature over 50ºC can cause severe
burns instantly or even death from scalding.
Children, disabled and the elderly are at the
highest risk of being scalded by excessively hot
water.
Always test the temperature of the water before
bathing or showering.
Burns from hot water taps can result in very
severe injuries to young children.
Hot water at 65°C can severely burn a child in less
than half a second. At 50°C it takes five minutes.
Burns can occur when children are exposed
directly to hot water or when they are placed into a
bath which is too hot.
x Consider child—resistant taps
or inexpensive tap covers, both
of which prevent a child’s hand
from turning on the tap.
x Consider reducing the
temperature of the water
supplied to the hot tap to 50°C.
This approach can be extremely
valuable because it requires a
one time action for a long term
reduction in risks of scalds.
This type of automatic protection
is important during times when a
parent or carer has been
distracted.

IMPORTANT INFORMATION
Always check water temperature before
use.
Refer to warning about hot water on
page 6 for important safety information.
Hot water may go cold without warning at
very low water flows (less than 3 l/min.)
The delivered water temperature is
controlled automatically. The water from
the hot tap may be reduced after the
temperature shown on the remote control
is raised. The water flow may also vary
with the temperature of the incoming
water supply.
Keep flammable materials, trees, shrubs,
chemicals, etc. away from the flue outlet /
terminal.
Do not spray water into flue terminal
Do not touch the flue outlet. Do not insert
objects into the flue outlet / terminal.
On cold days steam may be discharged
from the flue outlet. This is normal, do
not be alarmed. It does not indicate a
fault.
If freezing temperatures are expected, turn
off the water and gas, and drain the water
heater.
If the power is left on the Automatic Frost Protection
will prevent the unit from Freezing. Frost protection
is standard on all units.

Rinnai Infinity products have no pilot light and operate automatically as soon as water flow is
sensed.
The burner ignites with electronic ignition and the flame extinguishes as soon as water
flowing through the appliance stops.
Turn On by opening the hot water tap
The Rinnai Infinity range of water heaters are factory preset to a
temperature of 55°C; the HD range are preset to 65°C. Other limits, lower or
higher, are available on request. Temperature controllers are available to
allow precise digital temperature control. Controllers can be installed at any
time after installation of the hot water unit.
Excessively hot water is dangerous. Rinnai water heaters allow you to
control the temperature of your hot water to a safe level.
Water temperatures above 50°C can cause severe burns instantly, such
scalding may even result in death. Those most at risk are children,
disabled, elderly and the infirm. Hot water at 65°C (a very common water
temperature in the UK) can severely burn a child in less than half a
second. At 50°C it takes five minutes.
Consider using Thermostatic Mixing Valves on the Hot Water Outlets.
OPERATION WITHOUT REMOTES
CAUTION
NOTE
The new series of Rinnai Water Heaters have a built in status monitor on the front.
The status monitor has three conditions:
1 - The water heater is off (no water flowing): the monitor is blank.
2 - The water heater is on (heating water): The monitor displays the set
temperature.
3 - The water heater should be on, but is not (water is flowing, heater is
not on): The monitor will display a flashing error code.

TEMPERATURE CONTROLS
The purpose of a Temperature Controller is to enable the user to have localised control
over the hot water supply. Used correctly, the hot water unit will supply hot water at the
temperature selected, even when the water flow is varied, or when more than one tap is
used. Adjustments to the operation of your hot water unit can be made with any of the
Temperature Controllers. Each Temperature Controller can be individually programmed.
Up to four Universal and/or Deluxe Temperature Controllers can be fitted with Rinnai
water heaters. Universal Controllers allow temperature selection only and one comes as
standard with the water heaters. Deluxe Temperature Controllers are an optional extra.
These controllers have temperature selection, bath fill, voice prompt, and time clock
functions. When more than one Universal Controller is used one may be set as the
Master Controller to allow temperatures above 50°C.
Various water temperatures (°C) can be selected as follows:
Universal Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 500C
Master Universal Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C ( 60, 65°C HD )
Deluxe Bathroom Controller:
Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Bath fill Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48°C
Deluxe Kitchen Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C ( 60, 65°C HD )
If a temperature of 43°C or higher is selected on any controller and this temperature is
then decreased to below 43°C and increased again whilst the water is running, the
maximum selectable temperature will be 43°C. This provides additional safety for the
user.
Suggested temperatures are:
Kitchen 50°C - 65°C*; Shower 39°C - 43°C; Bath fill 39°C - 45°C
* This temperature may not be available on all installations.
These temperatures are suggested starting points for selection. You may find higher or
lower temperatures are more comfortable. Maintaining lower temperatures helps to save
energy. To obtain water temperatures lower than 37°C simply add cold water.
When multiple temperature controllers are used they allow the temperature to be set
from various locations by pushing the transfer button which gives that controller priority
over the system. The temperature selected by the controller with priority will be available
to all outlets.

10
TEMPERATURE CONTROLS - OPERATING
Safety features
Whilst the hot water tap is open, the
following safety features apply:
x Temperature selection cannot be
transferred.
x The temperature setpoint on the
controller with priority can always be
lowered, but the setpoint can only be
raised to 43°C.
x Other controllers are unable to take
priority or change the delivery
temperature of the water.
x If off, the controller cannot be turned on.
The temperature of the outgoing
water is constantly monitored by
a built in sensor.
If the temperature of the outgoing
hot water rises to more than 3ºC above the
selected temperature shown on the digital
display, or the preset limit if controllers are
not fitted, the burner will automatically go
out.
The red operation indicator will also go out.
The burner will ignite again once the
outgoing hot water temperature falls to that
shown on the digital display (or the pre-set
limit of the Rinnai Infinity heater).
Remote temperature controllers provide control over the water temperature. Rinnai water
heaters can be operated with 1, 2, 3, 4 or no temperature controllers.
Each time a button is pressed, a BEEP will sound. The BEEP sound can be
muted by depressing the Temperature Controller Up and Down buttons
simultaneously for more than 3 seconds. This can be done for each
Temperature Controller. To return to original settings, repeat this step.

symptoms, please carry out the suggestions below. If symptoms continue, please
contact Rinnai for advice.
NOTE: Faults caused by insufficient gas/water supply or gas/water quality and
installation errors are not covered by the manufacturer’s warranty.
Installations with circulation pumps
With temperature controller fitted.
If you have an installation using a secondary circulation pump this must be
switched off so that there is no flow through the heater when starting or after a
power failure. If the pump is running the unit will not operate (no display on the
controller). Isolate pump then start heater before restarting pump. This is a safety
feature.
The pump should also be fitted with a timer to prevent the consumption of energy
while the building is not used. The timer should bring the system back on at least
one hour before it is to be used.
Without temperature controller fitted.
The heater should automatically reset and provide water at the temperature set by
the internal limit switches.
Fault Remedy
Heater does not attempt
to start at all.
Check the power is on at the heater.
Check the cold water valve supplying the heater is open.
Heater starts then shuts
down immediately.

CARING FOR THE INFINITY
Maintenance
Even if there does not seem to be a problem with the water heater it is required in the UK
that all gas appliances are serviced every year by a certified gas engineer. This is to ensure
continued safety of the gas appliance. If you need a recommended service engineer contact
Rinnai or your supplier.
Care
When the appliance casing, operation panel, and remote controls surfaces become dirty
gently wipe them clean with a soft, damp cloth. Do not use detergents on these parts.
Filter
The water heater has a filter on the cold water inlet connection. This filter will need to be
cleaned occasionally. How often will be determined by the local water conditions. The water
filter can be located on the diagram on page 20. Isolate the cold water inlet and hot water
outlet with the valves near the heater. Release the pressure in the heater by unscrewing the
drain valve (shown on page 20.) Then remove the filter, clean it and replace it.
