1A GENERAL WARNINGS
The instruction manual is an integral part of the product and it must
therefore be kept carefully and must accompany the appliance; if
the manual is lost or damaged, another copy must be requested
from the Technical Assistance Service.
Boiler installation and any other assistance and maintenance
operation must be carried out by qualified personnel accord-
ing to current local and national regulations.
For installation, it is advisable to contact specialised personnel.
The boiler must only be used for the application foreseen by
the manufacturer. The manufacturer shall not be liable for
any damage to persons, animals or property due to errors in
installation, calibration, maintenance or due to improper use.
The safety and automatic adjustment devices must not be
modified, during the system life cycle, by the manufacturer or
supplier.
This appliance produces hot water, therefore it must be con-
nected to a heating system and/or a domestic hot water
mains, compatible with its performance and output.
In case of water leakage, close the water supply and contact
the Technical Assistance Service immediately.
In case of absence for long periods time, close the gas supply
and switch off the electrical supply main switch. In case of risk
of frost, empty the boiler.
From time to time check that the operating pressure of the
hydraulic system does not decrease under 1 bar.
In case of failure and/or malfunctioning, deactivate the appli-
ance, and do not try to repair or intervene directly on it.
Appliance maintenance must be carried out at least once a
year: program it with the Technical Assistance Service will
avoid wasting time and money.
Boiler use requires to strictly observe some basic safety rules:
Do not use the appliance in any manner other than its in-
tended purpose.
It is dangerous to touch the appliance with wet or damp body
parts and/or in bare feet.
Under no circumstances cover the intake grids, dissipation
grids and ventilation vents in the installation room with cloths,
paper or any other material.
Do not activate electrical switches, telephone or any other
object that causes sparks if there is a smell of gas. Ventilate
the room by opening doors and windows and close the gas
central tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not
disconnected from the main power supply.
Do not cover or reduce ventilation opening of the room where
the generator is installed.
Do not leave containers and inflammable products in the in-
stallation room.
Do not attempt to repair the appliance in case of failure and/
or malfunctioning.
It is dangerous to pull or twist the electric cables.
Children or unskilled persons must not use the appliance.
Do not intervene on sealed elements.
For better use, remember that:
- a periodic external cleaning with soapy water not only improves
its aesthetic aspect but also preserves panelling from corrosion,
extending its life cycle;
- if the wall-mounted boiler is enclosed in pendant furniture, leave
at least 5 cm for ventilation and maintenance;
- installation of an room thermostat will favour a greater comfort, a
more rational use of the heat and energy saving; the boiler can
also be connected to a programming clock in order to manage
ignition and switching off during the day or week.
2A IGNITION
First ignition must be carried out by personnel from the Technical
Assistance Service. At the same time, if it is necessary to put the
appliance in service again, carefully follow the described operations.
To start-up the boiler it is necessary to carry out the following op-
erations:
- power the boiler
- open the gas tap present in the system to allow fuel flow
- turn the mode selector (3 - fig. 1a) to the desired position:
Mynute Green C.S.I. E:
Summer mode: turning the selector to the symbol summer
3a) the traditional function of only domestic hot water is activated.
If there is a domestic hot water request the digital display shows
the hot water system temperature, the icon to indicate the hot water
supply and the flame icon
Winter mode: by turning the mode selector within the area marked
+ and - (fig. 3b), the boiler provides domestic hot water and heat-
ing. If there is a heat request, the boiler switches on and the digital
monitor indicates the heating water temperature, the icon to indi-
cate heating and the flame icon (fig. 4a). If there is a domestic hot
water request, the boiler switches on and the digital display shows
the hot water system temperature, the icon to indicate the hot water
supply and the flame icon (fig. 4b)
Pre-heating (faster hot water): rotate the domestic hot water tem-
perature adjustment knob (4 - fig. 1a) to the
to activate the pre-heating function. This function keeps the water
in the domestic hot water exchanger hot, to reduce standby times
when a request is made. When the pre-heating function is enabled,
the monitor indicates the delivery temperature of the heating water
or the domestic hot water, according to the current request. During
burner ignition following a pre-heating request, the monitor indicates
the
symbol (fig. 5b). To deactivate the pre-heating function, rotate
the domestic hot water temperature adjustment knob back to the
symbol. Bring the domestic hot water temperature adjustment
knob back to the required position. This function cannot be activated
when the boiler is OFF: function selector (3 fig.1a) on
Positioning the mode selector to
hot water temperature adjustment knob (4 - fig. 1a) to the
symbol, the chimney sweep function is activated (for exclusive
use of the Technical Assistance Service).
Mynute Green R.S.I. E:
Summer mode (only with the external water tank connected):
turning the selector to the symbol summer
tional function of only domestic hot water is activated and the boiler
supplies water at the temperature set on the external storage tank.
If there is a domestic hot water request the digital display shows
the hot water system temperature, the icon to indicate the hot water
supply and the flame icon
Winter mode: by turning the mode selector within the area marked
+ and - (fig. 3b), the boiler provides hot water for heating and - if
connected to an external storage tank - domestic hot water. If there
is a heat request, the boiler switches on and the digital monitor in-
dicates the heating water temperature, the icon to indicate heating
and the flame icon (fig. 4a). If there is a domestic hot water request,
the boiler switches on and the digital display shows the hot water
system temperature, the icon to indicate the hot water supply and
the flame icon (fig. 4b).
Adjust the room thermostat to the required temperature (~20°C)
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fig. 3b) within the area marked + and -.
Depending on the type of system, it is possible to pre-select the
suitable temperature range:
- standard systems 40-80°C
- floor systems 20-45°C.
For further details, consult the "Boiler configuration" section.
Adjusting heating water temperature with an external probe
connected
When an external probe is connected, the value of the delivery
temperature is automatically chosen by the system which rapidly
adjusts ambient temperature to the changes in external tempera-
ture.
