1 - GENERAL SAFETY DEVICES
The boilers produced in our factory are built with care down to the last
component to protect both the user and installer from eventual accidents.
We therefore recommend qualified personnel that after working on the
product they should pay particular attention to the wiring, especially the
bare wires, that must not be exposed outside the terminal board for any
rason to prevent any contact with the live parts of the wiring.
This instructions manual is integral parts of the product. Make sure they
remain with the boiler, even if it is transferred to another owner or user
or moved to another heating system. In case of loss or damage, please
contact your local Technical Assistance Service for a new copy.
This boiler may only be installed and serviced by qualified fitters who
satisfy the requirements of local rules. Work must be done in compliance
with regulations in force and subsequent updates.
The boiler must be serviced at least once a year. This should be booked
in advance with the Technical Assistance Service.
The installer shall instruct the user in the operation of the boiler and the
safety devices.
This boiler may only be used for what it was expressly built to do. The
manufacturer declines all contractual and non-contractual liability for
injury to persons or animals or damage to property deriving from errors
made during installation, adjustment and servicing and from improper
use.
This appliance is used to produce hot water and must therefore be
connected to a heating and/or a domestic hot water system, according
to its performance and power
After removing the packaging, make sure the contents are undamaged
and complete. If this is not the case, contact your dealer.
The safety and automatic adjustment devices on the appliance must
never be modified during its lifetime, except by the maker or dealer.
If the appliance develops a fault and/or works badly, switch it off and do
not attempt to repair it yourself.
Immediately after installation, inform the user that:
• in the event of leaks, he/she must shut off the water supply and
promptly inform the Technical Assistance Service
• the operating pressure of the system ranges between 1 and 1,5 bar
and must never be greater than 3 bar. If necessary, contact the
Technical Assistance Service
• if the boiler is not planned to be used for a long period, he/she should
call in the Technical Assistance Service to perform the following
operations:
- turn off the main boiler and general system switches
- close the gas and water taps on both the heating (C.S.I. - R.S.I.)
and domestic hot water circuits (C.S.I.)
- drain the heating (C.S.I. - R.S.I.) and domestic hot water (C.S.I.)
circuits to prevent freezing.
Connect the outlet collector to a suitable outlet system (refer to chapter
5).
Safety measures:
The boiler should not be used by children or unassisted disabled people
Electrical devices or equipment, such as switches, appliances, etc.,
should not be used if there is a smell of gas or fumes. If there is a gas
leak, open all the doors and windows to ventilate the area, turn off the
general gas tap and immediately call the Technical Assistance Service.
Do not touch the boiler barefoot or if parts of your body are wet or damp.
Move the function selector to OFF-RESET until "- -" is shown on the
display and disconnect the electricity supply by turning off the two-
position system switch, before cleaning.
It is forbidden to modify the safety or adjustment devices without the
manufacturer's permission and relative instructions.
Do not pull, detach or twist the wires from the boiler even if they are not
connected to the power supply.
Do not block or reduce the size of the ventilation openings in the room.
Do not leave inflammable containers or substances in the room.
The following symbols are used in this manual:
CAUTION= operations requiring special care and adequate
preparation
NOT ALLOWED= operations that MUST NOT de performed
R.S.I - DHW functions refer only if a water thank is connected
(accessory available on request).

Keep packaging out of reach of children.
Only use appliance for purposes it is devoted to.
Do not lean any object on the boiler.
Do not tamper with sealed elements.
It is forbidden to block the condensate outlet.
2 - BOILER INSTALLATION
Boiler must only be installed by qualified personnel in compliance with current
legislation. MYNUTE GREEN is available in the following models:
Model
28 C.S.I.-32 C.S.I.-36 C.S.I.
12 R.S.I.-15 R.S.I.-25 R.S.I.-35 R.S.I.
MYNUTE GREEN C.S.I. are type C wall-mounted condensation boilers for
heating and the production of domestic hot water.
MYNUTE GREEN R.S.I. are type C wall-mounted condensation boilers
capable of operating in different conditions through a series of jumpers fitted
on the electronic board (consult the "Boiler configuration" section):
CASE A: only heating. The boiler does not provide domestic hot water.
CASE B: only heating with an external thermostat-controlled water tank: in
this condition, the boiler delivers hot water to the water tank whenever a
demand is made by the relative thermostat.
CASE C: only heating with an external temperature probe-controlled water
tank (accessory kit available on request), for the production of hot water. If
the water tank is not supplied by our company, make sure that the relative
NTC probe has the following characteristics: 10 kOhm at 25°C, B 3435 ±1%.
This kind of appliance can be installed in any kind of room and there are no
limits as to ventilation or volume.
Depending on which fumes discharge accessory is used, it is classified in
the following categories B23P; B53P; C13,C13x; C23; C33,C33x; C43,C43x;
C53,C53x; C63,C63x; C83,C83x.
To position the boiler correctly, bear in mind that:
• it must not be fitted over a cooker or other cooking appliance
• it is forbidden to leave inflammable substances in the room
• suitably insulate heat-sensitive walls (e.g.: in wood)
• in order to allow access to the inside of the boiler for routine maintenance
operations, the minimum installation distances must be observed: at least
25 mm on each side and 200 mm under the boiler.
The boiler is supplied standard with a support plate featuring a built-in template
(fig. 2.1) and a gas tap. Hydraulic kits are available as accessories.
The position and size of the water connectors are shown in detail.
Install as follows (fig. 3.1):
• put the boiler support plate (F) with the pre-assembly template (G) to the
wall and use a spirit level to check they are perfectly horizontal
• mark out 4 holes (Ø 6 mm) for fixing the boiler support plate (F) and 2
holes (Ø 4 mm) for fixing the pre-assembly template (G)
• check the measurements and then drill the holes in the wall using a drill
and the correct size of bit as shown above
• fix the plate with the built-in template to the wall.
Connect to the water supply.
2.1 - Cleaning the system and characteristics of heating circuit water
After installing a new system or replacing a boiler, clean the heating system.
To ensure the product works correctly, after cleaning, additivating and/or
chemically treating the system (e.g.: anti-freeze, film-formers, etc.), make
sure the characteristics of the water satisfy the parameters indicated in the
table.
