ferred to another plant. If it is damaged or lost, request an-
other copy from your local Technical Assistance Service R.
1.2 Precautions
The operation of any appliance that uses fuel, electrical power
and water demands that a number of fundamental safety pre-
cautions be respected:
0 Do not allow children or inrm persons to operate the sys-
tem unsupervised.
0 It is forbidden to use electrical devices or equipment, such
as switches, appliances, etc. if there is a smell of gas or un-
burnt products. If so:
−Ventilate the room, opening doors and windows
−Close the fuel shut-off cock.
0 Do not touch the boiler while barefoot or wet.
0 Never clean or service the boiler without rst disconnect-
ing it from the mains electricity supply by turning the mains
power switch and the control panel switch OFF.
0 Do not tamper with or adjust the safety or control devices
without prior authorisation and instructions from the man-
ufacturer.
0 Never pull, disconnect, or twist the electrical cables coming

GENERAL INFORMATION
1.3 Description of the appliance
The INSIEME EVO 32 B/100-32 B/100 S boiler produces hot water
for central heating and also produces domestic hot water in an
integrated 95 litre storage cylinder.
It can function at low temperature and is oil fuelled.
The single stage oil burner has a horizontal steel combustion
chamber.
Model INSIEME EVO 32 B/100 S (unlike model INSIEME EVO 32
B/100) has a sealed chamber.
The boiler body is thoroughly and effectively insulated with a
layer of high density glass wool.
The INSIEME EVO 32 B/100-32 B/100 S boiler's control logic in-
corporates a total shutdown function to minimise energy con-
sumption:
−In "Summer" mode ("Summer/Winter" selector turned to
Summer position), the burner only starts up to restore
the setpoint temperature of the water in the storage
cylinder. In "Winter" mode ("Summer/Winter" selector
turned to Winter position), the burner starts up either in
response to a request for heat from the heating system
(i.e. when the room thermostat switches the heating on)
or to restore the setpoint temperature of the water in the
storage cylinder (DHW heat requests are prioritised over
central heating requests).
1.4 Safety devices
INSIEME EVO 32 B/100-32 B/100 S boilers incorporate the follow-
ing safety and control devices:
−A manual reset safety thermostat that forces a safe-
ty shutdown if boiler temperature exceeds the safety
threshold (100°C). The sensor used to monitor this tem-
perature is located on the body of the heat exchanger;
−A minimum temperature thermostat that enables the
central heating pump only if boiler temperature exceeds
the minimum permissible (50°C);
−A maximum temperature thermostat that shuts down
the burner if boiler temperature reaches or exceeds the
default maximum limit ( 82°C) during the heating of do-
mestic hot water in the storage tank;
−An electronic burner controller that monitors the correct
functioning of the selected burner program and sends
a lockout signal to the control panel in the event of an
error.
9 The intervention of a safety device indicates a potentially
dangerous malfunction in the system. Contact the manu-
facturer’s Technical Assistance Service immediately.
9 Safety devices must only be replaced by the manufacturer's
Technical Assistance Service using original spare parts. Refer
to the spare parts catalogue supplied with the boiler.
0 Do not use the boiler if any of its safety devices are faulty.
Always check that the boiler is functioning correctly after repairs
have been made.
