General Installation Information.
External Installations.
The Rinnai Infinity 20e and Infinity 16e are for external mounting only.
The unitsare classedas Category A3 flueless appliancesas described by CEN CR1749.
Although BS 5440 does not relate directly to heaters in this category the rules must be
followed when positioning the appliance, especially with regard to other appliances,
openings, and boundaries. Figure C.1 from BS5440-1:2000 is provided for your
guidance.
The appliance must be mounted on a vertical wall or structure with the water and the gas
connections on the underside pointing towards the ground.
THIS APPLIANCE MUST NOT BE USED AS A DOMESTIC SPA OR SWIMMING
POOL HEATER.
Appliance Location.
The appliance should be placed as close as practicable to the most frequently used hot
water outlet point or points to minimise the delay time for hot water delivery. For
installations where the distance between the unit and hot water outlet points is
considerable, the appliance can also be fitted in a 'flow and return system' which
minimises the waiting time for hot water delivery. Alternatively, multiple appliances can
be strategically placed to service outlet points with minimal delay time. Contact Rinnai
for further information.
Location of the appliance flue terminal must be in accordance with the clearances shown
on page 8. Ensure that the flue terminal and hot water outlet connection cannot be
touched by children. The appliance must be clear of obstructions and shrubbery.
The wall or structure on which it is mounted must be capable of supporting the weight of
the appliance (20e : 16kg , 16e : 15kg) and associated pipework. Ensure that suitable
screws or bolts are used to secure the water heater to the wall. Bracket and fixing hole
locations are shown on page 9. The top bracket has a keyhole slot so that the appliance
can be hung on one screw, and then the other fixings can be added to secure the unit.
The appliance must be in an accessible location. Sufficient clearances shall allow
access to, and removal of, all serviceable components. The appliance should not be
mounted higher than 3.5 metres from the ground or floor level unless the customer can
arrange permanent and safe access or can arrange another means of access, for
example, by means of scissor or boom lifts.
Multiple heater installations can be installed with the heaters manifolded together.
The design of the heater draws combustion air through the casing for the external model.
Heater guards and pipe cover boxes for security and safety are available from Rinnai.

INSTALLATION INSTRUCTIONS - CONNECTIONS
Water Supply.
Where the water supply pressure exceeds 10 bar, an approved pressure reducing
device is required at the inlet of the appliance. To achieve the rated flow a minimum
water supply pressure of 1.0 bar is required at the appliance inlet. The unit will operate
at lower supply pressures but the rated flow will not be achieved. Contact Rinnai for
'gravity fed' or 'low pressure' hot water installations.
Water pipe sizing and layout should be designed correctly to ensure the given water
flows from the Rinnai Infinity are available. All hot water pipework should be insulated to
optimise maximum performance and energy efficiency.
Water Connection.
Connect the hot and cold water supply pipes. An approved isolation valve and strainer
MUST be installed in the cold water inlet pipe. An approved isolation valve should be
installed onthehot wateroutlet pipe.There must be a union or release fittingonthe
heater side of the isolation valves. A non return valve is not required unless dictated by
local regulations. A pressure relief valve should be installed in the pipework to
discharge safely into a suitable drain when the system has a flow and return, or tank.
Positions of the cold water inlet, hot water outlet and gas connections are shown on
page 9. Water connections are 1/2 inch BSP, gas is 3/4 inch BSP. This is NOT an
indication of the pipe sizes required.
If the heater is in a hard water area a suitable water conditioning device should be in-
stalled to prevent the build up of limescale within the heat exchanger. Heat exchangers
damaged by scaling are not covered by the manufacturer’s warranty. Guidelines are
given below. If the local water exceeds these values the heater must be protected.
Gas Connection
Check pipe sizing required for the heater input. The heat input for the Infinity 20e is 44.4kW.
The heat input for the Infinity 16e is 34.7kW. Refer to BS6891 (Natural Gas) and BS5482.
(Propane) for guidance on correct pipe sizing calculation.
Check that the size of the gas meter and pipework will be sufficient for all appliances on
the main. Sufficient gas must be available at the appliance if correct operation is to be
expected. An approved gas isolation valve must be fitted at the gas inlet. A union or
release fitting should be installed after the isolation valve.
Electrical Connection.
The appliance must be earthed. The appliance is suitable for 230VAC – 50Hz mains
only and all wiring must be carried out to the I.E.E regulations latest edition. The heater
electrical supply must be provided with a fused (3A) local isolator with a contact
separation of 3mm minimum on all poles for servicing. Observe polarity and ensure that
wiring is correctly restrained.

Congratulations on purchasing the Technologically Advanced, Temperature Controlled,
Rinnai Hot Water System.
•The Rinnai Infinity 20e and Infinity 16e 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.
•Built into the main micro-processor is the facility to LIMIT THE MAXIMUM
TEMPERATURE of the hot water supplied. The water temperature may be limited to
various maximum temperatures. This is particularly useful when the hot water unit is
installed where young children or the infirm may be using the hot water. The Infinity
20e and Infinity 16e delivered with a preset temperature of 55°C. If required, the
temperature limits can be changed by an authorised person. For further information,
please contact Rinnai.
•TheRinnai Infinity external units are powered flue appliances. This makes them
COMPACT, saving both floor and wall space.
•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.
•The burner lights automatically when the hot water tap is opened, and distinguishes
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.
•Up to three temperature controllers can be mounted remotely from the heater. This
offers the following additional features:
Localised temperature setting.
Diagnostic message.
•‘Deluxe’ Temperature Controllers are an optional extra. These provide functions
including Bath Fill, Voice Prompt, and Clock Setting.
•Temperatures selected at the controllers are retained in the SYSTEM MEMORY.
•Operating NOISE LEVEL IS VERY LOW.
•ERROR MESSAGES ARE DISPLAYED on the Temperature Controllers, assisting
with service.
•FROST PROTECTION device built in as standard.
FEATURES AND BENEFITS

12
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
Infinity 20e or Infinity 16e 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.
DO
•Consider child—resistant taps
or inexpensive tap covers,
both of which prevent a child’s
hand from turning on the tap.
•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.
DO
NOT

13
IMPORTANT INFORMATION
Always check water temperature before
use.
Refer to warning about hot water on
page 12 for important safety information.
Hot water may go out without warning at
low water flows.
The Infinity 20e and Infinity 16e control
the water temperature automatically. For
high temperatures it may reduce the flow.
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 heater.
Do not touch the unit cover or the flue
outlet. Do not insert objects into the flue
outlet.
On cold days steam may be discharged
from the flue outlet. This is normal, do
not be alarmed. It does not indicate a
fault.

TEMPERATURE CONTROLS - GENERAL
When deciding on the best position for the temperature controls, the following points
should be taken into account.
•Fit the controls out of reach of children (suggested height from the floor 1.5m.)
•Avoid positions where the controllers will become hot. Do not fit them near stoves or
ovens, or above radiators or heaters.
•If possible, avoid exposure to direct sunlight or positions where bright lights will make
the digital display difficult to read.
•Position away from areas where the controller will be prone to splashing by cooking
products such as oils and fats.
•The temperature controllers are water resistant, however they should be positioned
away from areas where direct or persistent splashing could occur.
•Refer to the I.E.E electrical wiring regulations current edition for location requirements
in shower and bath areas.
•The cables to the temperature controller carry only 12VDC (extra low voltage.)
•When using more than one temperature controller the signal cable should be run in
parallel. That is, from controller to controller to heater, or from each controller to the
heater. Do not wire the controllers in series.
The installation in every application will vary, therefore the temperature controller cable
has been provided so that you may cut the length accordingly and fit the spade
connectors, ensuring a good connection.
Cables are simply ‘piggy-backed’ at the water heater or at the primary temperature
controller. Polarity is not important when connecting the cables, either colour wire can
be connected to either terminal at both the heater or primary temperature controller. If
more cable is needed any cable with similar specification to the cable supplied with the
controller can be used. Maximum length is 50 metres.

TEMPERATURE CONTROLS
The purpose of a Temperature Controller is to enable the user to have complete 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 three Universal and Deluxe Temperature Controllers can be fitted with the Infinity
20e and 16e. Universal Controllers allow temperature selection only and come as
standard with the water heaters. Deluxe Temperature Controllers are an optional extra.
These controllers have temperature selection, bath fill, voice recognition, and time clock
functions. When more than one Universal Controller is used one may be set as the
Master Controller to allow higher temperatures.
Various water temperatures (°C) can be selected as follows:
Universal Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Master Universal Controller:
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
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C
If a temperature 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 become 43°C. This provides additional safety for the
consumer.
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.
Up to three controllers can be used for one Infinity 20e or Infinity 16e. 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.

19
Remote temperature controllers are a feature that provides control over the water
temperature. Rinnai Infinity water heaters can be operated with 1, 2, 3, or no
temperature controllers. The Universal controller MC-91-1A comes as standard with all
Infinity water heaters.
NOTE:
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.
