DESCRIPTION OF THE APPLIANCE
5.1
Characteristics
Brava Slim BF
are last generation low temperature wall mounted
boilers which Sime has produced for heating and domestic hot
water production. The main design choices made by Sime for the
boilers are:
Brava Slim BF
– the atmospheric burner combined with a copper heat exchang-
er for heating and a rapid heat exchanger for DHW
– the sealed combustion chamber which can be classified "Type
C" or "Type B" in relation to the room where the boiler is in-
stalled, depending on the smoke outlet configuration adopted
during installation
– the command and control microprocessor electronic board
provides efficient management of both heating and hot water
production. It can also be connected to a remote control with
an Open Therm protocol or to room thermostat and/or external
sensor. If connected to an external sensor, the boiler tempera-
ture varies on the basis of the external temperature according
to a selected optimal climatic curve providing significant ener-
gy and economic savings.
Other special features of the Brava Slim BF boilers are:
– the anti-freeze function which activates automatically if the
temperature of the water inside the boiler falls below the
threshold of the value set at parameter "PAR 10" and , if there
is an external sensor, if the external temperature falls below
the threshold of the value set at parameter "PAR 11"
– the anti-blocking function of the pump and diverter valve, this
activates automatically every 24 hours if no request for heat
has been made
– the chimney sweep function lasts 15 minutes and makes the
job of the qualified technician easier when measuring the pa-
rameters and combustion efficiency and when checking gas
pressure at the nozzles
– domestic hot water comfort function which allows the time
necessary for the hot water to become available to be reduced
and ensures that the temperature is stable
– screen display of the operating and self-diagnostic parameters
with error code display when the fault occurs. This makes re-
pair interventions easier and allows appliance operation to be
restored correctly.
5.2
Check and safety devices
The Brava Slim BF boilers are equipped with the following check
and safety devices:
– thermal safety sensor 100°C
– 3 bar relief valve
– heating water pressure transducer
– delivery sensor
– DHW sensor.

Identification
The Brava Slim BF boilers can be identified by means of:
this is located on the outside of the packag-
1
Packaging label:
ing and provides a code, the serial number of the boiler and
the bar code
2
Technical Data Plate:
this is located inside the front panel of
the boiler and provides the technical specification, appliance
performance and any other information required by law.

CAUTION
Tampering with, removing or failing to display the
identification plate or carrying out any other operation
which does not allow safe identification of the product
or which may hinder installation and maintenance op-
erations.
