1 DESCRIPTION OF THE APPLIANCE

1.1 Characteristics

Brava One 40 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 Brava One 40 BF boilers are:

• the atmospheric burner combined with a copper heat exchanger 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 installed, 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 Brava One 40 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 "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 parameters 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 repair interventions easier and allows appliance operation to be restored correctly.

1.2 Check and safety devices

The Brava One 40 BF boilers are equipped with the following check and safety devices:

• thermal safety sensor 100°C
• 3 bar relief valve
• heating water pressure switch
• delivery sensor
• DHW sensor.

IT IS FORBIDDEN

to commission the appliance with safety devices which do not work or which have been tampered with.

WARNING

Safety device may only be replaced by professional qualified personnel using Sime original spare parts.

1.3 Identification

The Brava One 40 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

• For further information on the type of additive and usage, please contact the appliance manufacturer.
• Please remember that you MUST install a Y filter (not supplied with the appliance) on the heating system return (R).

2.7 Water system treatment

When filling and restoring the system it is good practice to use water with:

- aspect: clear if possible

- pH: 6÷8

- hardness: < 25°f.

If the water characteristics are different from those indicated, it is recommended that a safety filter is used on the water delivery pipe to retain impurities, and a chemical treatment system to protect against possible deposits and corrosion which could affect boiler operation.

If the systems are only low temperature systems, it is recommended that a product is used to prevent the development of bacteria.

In any case, please refer to and comply with the legislation and specific technical standards in force in the country where the appliance will be used.
