5 DESCRIPTION OF THE APPLIANCE
5.1 Characteristics
OF-BF
are last generation low temperature wall mounted boilers
which Climit has produced for heating and domestic hot water
production. The main design choices made by Climit for the OF-BF
boilers are:
– the atmospheric burner combined with a copper heat exchan-
ger 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 not
only allows a better management of the heating system and
the system for domestic hot water production but it can also
be connected to air thermostats or a remote control (with an
Open Therm protocol), an auxiliary sensor for the connection
of any possible solar kits or to an external sensor. If this is the
case, the boiler temperature varies on the basis of the external
temperature according to the selected optimal climatic curve
allowing for significant energy and economic savings.
Other special features of the
OF-BF
boilers are:
– the anti-freeze function which activates automatically if the
temperature of the water inside the boiler falls below the thre-
shold of the value set at parameter "tS 1.0" and , if there is an
external sensor, if the external temperature falls below the
threshold of the value set at parameter "tS 1.1".
– 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 parame-
ters and combustion efficiency and when checking gas pressure
at the nozzles
– 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
OF-BF
boilers are equipped with the following check and sa-
fety devices:
– thermal safety sensor 100°C
– 3 bar relief valve
– heating water pressure switch
– delivery sensor
– DHW sensor.
d
IT IS FORBIDDEN
To commission the appliance with safety devices which
do not work or which have been tampered with.
a
WARNING
Safety device may only be replaced by professional qua-
lified personnel using
Climit
original spare parts.
5.3 Identification
The
OF-BF
boilers can be identified by means of:
1 Packaging label: this is located on the outside of the packaging
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 iden-
tification plate or carrying out any other operation which
does not allow safe identification of the product or which
may hinder installation and maintenance operations.
