2 - BOILER DESCRIPTION

Mynute LOW NOx 24 C.S.I. is a C-type wall-mounted boiler with
low NOx emissions for heating and production of domestic hot wa-
ter: according to the flue gas outlet device, the boiler is classified
in categories B22P, B52P, C12, C32, C42, C62, C82, C92, C12x,
C32x, C42x, C62x, C82x, C92x.
In configuration B22P and B52P (when installed indoors), the ap-
pliance cannot be installed in bedrooms, bathrooms, showers or
where there are open fireplaces without a proper air flow. The room
where the boiler is installed must have proper ventilation.
In configuration C, the appliance can be installed in any type of
room and there are no limitations due to ventilation conditions or
room volume.

3 - INSTALLATION REGULATIONS

3.1 Installation regulations
Installation must be carried out by qualified personnel.
Always comply with national and local regulations.
POSITION
Mynute LOW NOx 24 C.S.I. can be installed indoors (fig. 9).
The boiler has protection that guarantees correct operation with a
temperature range from 0°C to 60°C.
To take advantage of protections, the appliance must be able to
start up, since any lockout condition (for example, absence of gas
or electrical supply, or safety intervention) deactivates the protec-
tions.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular mainte-
nance operations, respect the minimum spaces foreseen for instal-
lation (fig. 10).
For correct appliance positioning:
- do not place it on a cooker or other cooking device
- do not leave inflammable products in the room where the boiler
is installed
- heat sensitive walls (for example, wooden walls) must be pro-
tected with proper insulation.
IMPORTANT
Before installation, wash every system piping carefully in order to
remove any residues that may impair the operation of the appli-
ance.
