1.4 Responsibilities
1.4.1 User's responsibility
You must respect the following instructions to guarantee the optimum operation for the installation:
• Read and follow the instructions provided in the manuals supplied with the unit.
• Call on a qualified professional to carry out the installation and start the unit up for the first time.
• Have the installation explained by the installer.
• Have the necessary inspections and servicing carried out by a qualified professional.
• Keep the manuals in good condition and close to the unit.
1.4.2 Installer's responsibility
The installer is responsible for installing the unit and for starting it up for the first time. The installer is required to respect
the following instructions:
• Read and follow the instructions provided in the manuals supplied with the unit.
• Install the unit in accordance with current legislation and standards.
• Start up the unit for the first time and carry out all the necessary checks.
• Explain the installation to the user.
• Alert the user to the obligation to have the unit inspected and serviced each year.
• Hand over all the manuals to the user.
1.4.3 Manufacturer's responsibility
Our products are manufactured according to the different applicable directives. Therefore, they are delivered with marking
and all the necessary documents. To ensure the quality of our products we are constantly seeking to improve them. We
therefore reserve the right to modify the characteristics indicated in this document.
As manufacturer, we cannot be held responsible in the following cases:
• Failure to follow the unit's usage instructions.
• Insufficient or lack of servicing of the unit.
• Failure to follow the unit's installation instructions.
• Flame ionisation electrode
The flame detection electrode guarantees safety in the event of gas disconnection or poor burner ignition. In this case it
turns off the boiler.
• Hydraulic pressure controller
This device allows the burner to start only if the water pressure is above 0.5 bars.
•
Heating circulator with post-circulation
The electronic control allows the heating pump a post-circulation of 3 minutes after stopping the burner in heating mode
if the room thermostat calls for the burner to stop.
• Antifreeze protection
The boiler's electronic control system included in heating mode or domestic hot water production has a protection
against frost. If the water temperature falls below 6°C the burner starts working to reach a temperature of 30°C.
This function is only valid if the boiler is lit, gas is open, and water pressure is correct.
• Circulator blockage protection
If no request for heating or domestic hot water is received for 24 hours, the circulator starts automatically for 10 seconds
to avoid any blockage.
• Blockage protection in 3-way valve
If no heating demand is received for 24 hours, the 3-way valve automatically performs a complete operating cycle.
• Safety valve (heating circuit)
This device limits the pressure in the heating circuit to 3 bars.
Do not use to drain the heating circuit.
• Heating circulator with pre-circulation
In the case of heat in heating mode, the unit can operate the pre-circulation pump before lighting the burner. This
precirculation phase may last a few minutes depending on the operating temperature and the installation conditions.
