1.1 General safety instructions

Danger This appliance is not intended to be used by persons (including children) whose physical, sensory or mental capacity is impaired or persons with no experience or knowledge, unless they have the benefit, through the intermediary of a person responsible for their safety, of supervision or prior instructions regarding use of the appliance. Care should be taken to ensure that children do not play with the appliance.

Warning Only qualified professionals are authorised to work on the boiler and the heating installation.

Danger of electric shock A disconnection device must be fitted to the perma nent pipes in accordance with installation rules.

Danger of electric shock

Danger If you smell flue gases:

1. Switch off the appliance.

2. Open the windows.

3. Evacuate the premises.

4. Contact a qualified professional.

Warning Do not touch the flue gas pipes. Depending on the boiler settings, the temperature of the flue gas pipes may exceed 60°C.

Warning Do not touch the radiators for long periods. Depending on the boiler settings, the temperature of the radiators may exceed 60°C.

Warning Take precautions with the domestic hot water. De pending on the boiler settings, the domestic hot water temperature may exceed 65°C.

Danger of electric shock If the power cable is damaged, it must be replaced by the manufacturer, its after sales service or persons with similar qualifications in order to obviate any dan ger.

1 Safety

7615193 - v01 - 09072015 EFU 5

Caution Do not neglect to service the boiler. Contact a quali fied professional or subscribe to a maintenance con tract for the annual servicing of the boiler.

Caution Only genuine spare parts may be used.

1.2

Recommendations

Caution The installation must satisfy each point in the rules (DTU, EN and others, etc.) that govern works and in terventions in individual homes, blocks of flats or other buildings.

Note Keep the boiler accessible at all times.

Caution Install the boiler in a frost-free location.

Caution The appliance should be on Summer or Antifreeze mode rather than switched off to guarantee the follow ing functions:

Anti-blocking of pumps Frost Protection

Note Regularly check the presence of water and pressure in the heating installation.

Note Never remove or cover labels and data plates affixed to the appliances. Labels and data plates must be legible throughout the entire lifetime of the appliance. Immediately replace damaged or illegible instructions and warning stickers.

Note Remove the casing only to perform maintenance and repair work. Put the casing back in place after mainte nance and repair work.

Note Insulate the pipes to reduce heat losses to the mini mum.

Caution If the home is unoccupied for a long period and there is a risk of frost, drain the boiler and the heating sys tem.
