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.

●
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,

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.
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 con-
figuration" 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-con-
trolled water tank (accessory kit available on request), for the pro-
duction of hot water. If the water tank is not supplied by our com-
pany, 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) 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:
- 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.
Cleaning the system and characteristics of heating circuit water
After installing a new system or replacing a boiler, clean the heat-
ing 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 sat-
isfy the parameters indicated in the table.
