such as switches, home appliances, etc., if you smell gas or
fumes. In the event of gas leaks, ventilate the room opening
doors and windows; close the gas general tap; contact the
qualified personnel from the Technical Assistance Service im-
mediately
Do not touch the boiler while barefoot or if parts of your body
are wet or damp
Before cleaning operations, disconnect the boiler from the
main power supply by turning "OFF" the two position system
switch and the main control panel switch
Do not modify safety and adjustment devices without the
manufacturer's permission and relative instructions
Do not pull, disconnect or twist the electric cables coming
out of the boiler even when it is disconnected from the main
power supply
Avoid covering or reducing the size of ventilation openings of
the installation room
Do not leave inflammable containers and substances in the
installation room
Keep packaging materials out of reach of children.
C.A.I. models: do not cover or reduce the size of the ventila-

ventilation openings are vital for correct combustion.

2 - BOILER DESCRIPTION

Mynute Boiler B.A.I. is a wall-mounted type B11BS boiler for heat-
ing and the production of domestic hot water, supplied with a 60
liters inox water tank. This type of appliance cannot be installed
in bedrooms, bathrooms or showers, or in rooms with open flues
without adequate ventilation.
Mynute Boiler B.S.I. is a C-type wall-mounted boiler for heating
and production of domestic hot water supplied with a 60 liters inox
water tank (28 B.S.I.) - 45 liters inox water tank (24 B.S.I.): accord-
ing to the flue gas outlet device, the boiler is classified in catego-
ries B22P, B52P, C12, C22, C32, C42, C52, C62, C82, C92, C12x,
C32x, C42x, C52x, 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.
The boiler is fitted with the following safety devices:
- Safety valve and water pressure switch intervening in cases
of insufficient or excessive water pressure (max 3 bar-min 0.7
bar).
- Temperature limit thermostat intervening by putting the boiler
into safety stop if the temperature in the system exceeds the limit
according to current local and national regulations
- Mynute Boiler B.A.I.: Fumes thermostat intervenes by block-
ing the boiler into a safety standstill status if there is a spillage of
combustion products in the hood; it is located on the right hand
tile of the vent-damper draught breaker device Intervention of
safety devices indicates a potentially dangerous boiler malfunc-
tion; contact the technical assistance service immediately.
The fumes thermostat not only intervenes for a fault in the com-
bustion products outlet system, but also with various atmospher-
ic conditions. One can therefore try to start up the boiler again
after waiting a short while (see first ignition section).
Repeated intervention of the fumes thermostat signifies
