Zen is a PREMIXED boiler with “CONTINUOUS MODULATION ON GAS AND AIR”. It is equipped with a LOW NOx
EMISSION metal ber burner: the emission values make it one of the most environmentally friendly products on the
market.
The Rinnai Zen boiler is a FORCED FLOW gas appliance, with HIGH ENERGY EFFICIENCY: these features make it
extremely compact, guaranteeing considerable space savings and drastically reducing gas consumption.
The Zen ‘I’ range is supplied with a WiFi ROOMTHERMOSTAT as a standard, showing the operating temperatures
(heating and DHW), error codes and the advanced boiler regulation functions. By activating the WiFi FUNCTION
and installing the application ‘My Rinnai’ it is possible to control and manage the main functions directly through
your SMARTPHONE. The application allows the installation up to a maximum of ten users per command and the
management of three dierent boilers: the whole family can enjoy maximum comfort and it is also possible to manage
the boiler of a second home or of the elderly, inexperienced parents.
THE NOISE DURING OPERATION IS EXTREMELY LOW.
The Zen serie is equipped with a CONDENSATE TRAP SIPHON FILLED WITH A NEUTRALIZER: you can waste
condensate, moderately acidic and corrosive, without fear of damaging the drain or the disposal plant.
It is equipped with a SAFETY SENSOR FOR EARTHQUAKES: in case of medium or high sismic events, the boiler
automatically isolates itself from the gas plant, thus limiting gas leaks, explosions or res, which can make the
environment aected by earthquake further dangerous.
The Zen serie is equipped with a PRE-INSTALLED CLIMATIC PROBE. It is no longer necessary to work hard to
install the external temperature sensor: the probe is already connected and installed, ready for use. By activating
the ‘automatic operation’, the boiler will adjust its combustion based on the external ambient temperatures, always
guaranteeing excellent comfort and reducing fuel consumption and waste. As an optional element it is however
possible to install a specic extension probe for outdoor environments.
With Rinnai’s Zen boiler, You will NEVER BE WITHOUT HOT WATER: as long as electricity, water and gas are
guaranteed, hot water is available every time a hot water tap opens.
Hot water is exclusively produced in an INSTANTANEOUS way: it is not stored in tanks with limited capacity, always
source of constant dispersions and high energy consumption.
The appliance is equipped with a special safety and comfort function that CONTROLS THE MAXIMUM TEMPERATURE
of the hot water supplied. The temperature can be adjusted to a precise value: this function is particularly useful when
the appliance is installed at the service of children, patients or elderly people. If necessary, the temperature can be
modied at will from the control panel (remote control), supplied as standard, to better serve the user. The temperature
of the hot water supplied is constantly monitored by several internal sensors.
ERROR CODES are displayed on the remote control to facilitate technical assistance: they appear as ashing numeric
codes on the display.
The range of Zen boiler has an ‘IP 5’ PROTECTION RATE and can be freely installed in EXTERNAL ENVIRONMENTS,
directly exposed to atmospheric agents without particular protection (the correct installation of the ue gas tting is
necessary).
ANTIFROST PROTECTION is included as standard on each model: the appliance is protected up to -20°C.

1.4 OPERATION
IMPORTANT
Before to use the boiler, it is advisable to know how it properly works.
The operation of the boiler and the main functions that can be activated are described below.
Before using the boiler, make sure that the heating circuit is always lled correctly: when the
system is still cold, the pressure gauge on the front panel must indicate a value in the green
sector (0.5 ÷ 1.5bar). If necessary, restore the correct value by operating the ll/load tap at the
base of the boiler.
When the boiler is electrically connected, an automatic venting program is activated. It can
last from 60 to 120 minutes depending on the system. It is necessary to wait until the end of
the cycle to allow the expulsion of all the air that was formed in the installation phase (or in the
period of non-use). Press a button on the remote control causes the early stop of the venting
cycle and can cause problems. A particular noise can be a sign of the presence of air bubbles
still circulating in the pipes: unplug the boiler and re-plug it to repeat the venting cycle.
The boiler is ready for the use and a wireless chronothermostat is supplied as a standard. The command is pre-set
to control the ‘heating temperature’ of the system. To operate, the command must remain connected by cable to the
boiler: in case of remote installation it is possible to extend the electrical cable paying particular attention to use a
shielded cable in case it is positioned in the vicinity of high voltage electrical wiring.
The Rinnai condensing boiler can operate without the remote control connected: operated only by the control panel,
which is pre-assembled on the boiler (body controller). This basic conguration allows to:
activate/deactivate the heating mode and adjust the ow temperature of the heating system;
•
activate/deactivate the hot water supply, adjusting the temperature of the hot water;
•
check for malfunctions and error codes.
•
A second operation mode is by connecting the Rinnai WiFi chronothermostat, which is supplied as a standard with the
appliance. The main features available are:
select the heating mode (room temperature or ow temperature mode);
•
activate/deactivate the heating mode and adjust the ow temperature of the heating system;
•
activate/deactivate the hot water supply, adjusting the temperature of the hot water;
•
special functions use (fast heating; hot water pre-heat; Auto mode, Save, Reservation, etc);
•
check for malfunctions and error codes;
•
monitor the energy consumption;
•
adjustment of boiler’s operation parameters;
•
operation of the boiler through the ‘My Rinnai’ app and Your own samrtphone.
•
A third operation mode is made by connecting the boiler a third party thermostat in conjunction to the Rinnai WiFi one:
in this conguration the Rinnai remote is no more controlling the room temperature, but it can be still used to adjust the
hot water temperature. The third party thermostat is in control of the room heating temperature.
By activating the WiFi mode, the boiler can be operated and programmed by Your own Smartphone through the ‘My
Rinnai’ application (up to ten users can register and control the boiler). The main functions are all available and always
handy; more advanced and more specic ones are available, to manage and program the boiler. The application is
equipped with a simple introductory guide that explains its operation quickly and easy. The specic user manual for
the application is available on the Internet site: www.rinnai.it

1.4.4 HOT WATER RAPID HEATING AND PRE-HEATING FUNCTION
Rapid heating
The rapid heating function can be used to quickly restore the suitable temperature in a cold environment: the boiler
will operate at maximum power for twenty-ve minutes, in order to create the right conditions for a sudden rise in
temperatures in the installation.
At the end of this time interval, the boiler will go automatically back to the pre-set functioning.
To activate the rapid heating function, perform the following steps:
Activate the heating mode, by pressing the button ;
•
Press again for three seconds:
•
the display will show a temperature of 40°C if the boiler is set on
the’room temperature’ mode; or 80°C if the boiler is set on the ‘ow
temperature’ mode.
To deactivate the rapid heating function:
Turn the dial.

Hot water pre-heating function
Ambient temperature mode
Flow temperature mode
The pre-heating function consents to prepare the boiler for the provision of domestic hot water and to benet of a
superior comfort: pre-heat function allows a faster delivery of hot water at the desired temperature shortening the time
needed for its production.
When the function is activated, the hot water preparing circuit is immediately raised to the right temperature and
mantained hot for thirty minutes (or until rst use).
At the end of this time period (or after having used hot water), the boiler stops this function automatically in order to
reduce wasted energy and minimize the consumption, then returns to normal operation.

1.4.6 AUTO MODE (AUTO
NOTE
NOTE
)
Auto mode will be also indicated by the abbreviation AUTO.
The AUTO mode enables the boiler to adapt the regular ow temperature of the heating circuit to the values of the
outdoor ambient temperature, in complete autonomy. The auto mode only works on the heating mode and not on the
production of hot domestic water.
The device periodically monitors the external temperature in order to adjust the internal ow temperature by means of
a sensor: in the cold seasons, the boiler will be able to adjust the heating circuit’s water’s temperature proportionally to
the outdoor temperature reduction; the other way round, the boiler will lower the indoor temperature to adjust it to the
rising outdoor temperature in the warmer seasons.
The device works autonomously, adjusting its own functioning to the actual temperatures of the current season. This
provides a greater domestic comfort while reducing polluting emissions and fuel consumption.
To activate the AUTO mode, perform the following steps.:

1.4.6 ENERGY-SAVING MODE (SAVE
)
Energy-save mode will also be mentioned as SAVE.
Energy-saving mode exclusively operates on the heating mode and not on the domestic hot water production. When
the SAVE mode is on, the boiler modies the on/o operation of the burner. The dierent temperatures that is possible
to set with the chronothermostat are limited (in order to reduce energy consumption). So the maximum selectable
room temperature shall be 20°C and the maximum ow temperature shall be limited to 60°C.

The functioning of the ‘reservation mode’ will also be mentioned as RESERVATION.
The Rinnai Wi’s chronothermostat consents you to set time slots for the heating mode every day. It is possible to
program the favourite time slots during which the boiler must maintain a comfortable temperature and those during
which it is allowed to reduce the temperature (night time or whenever nobody is at home).
The specic time reservation works both in ‘room temperature’ mode and in ‘ow temperature’ mode and works
exclusively on the heating mode but not on the domestic hot water production.
To activate and program the RESERVATION mode, perform the following steps.:
