5.2 Starting up the boiler
1. Check that the storage tank is filled with fuel.
2. Open the oil inlet valve.
3. Switch on the boiler.
4. Check the hydraulic pressure in the installation indicated on the user
interface.
Important
Recommended hydraulic pressure between 0.15 and 0.2 MPa
(1.5 and 2.0 bar).
5. Confirm the selection by pressing the selector .
If the boiler is connected to a domestic hot water tank, the boiler
begins an automatic venting cycle that lasts around 3 minutes and
is repeated each time the power is cut. If there is a problem, an
error message is displayed on the home screen.
6. If an error message is displayed on the home screen, contact the
installer.
5.3 Shutting down the boiler
The boiler must be shut down in certain situations, for example during any
intervention on the equipment. In other situations, such as an extended
absence period, we recommend that the System holiday mode
operating mode is used in order to benefit from the boiler anti-blocking
function and to protect the installation from frost.
To shut down the boiler:
1. Switch off the boiler.
5 Operation

Selecting the operating mode, page 20
Periods of absence or going on holiday, page 24
5.4 Frost protection
Caution
The frost protection function does not work if the boiler is powered
off.
Caution
The integrated protection system only protects the boiler, not the
heating system.
Caution
Have the boiler and heating system drained by a qualified
professional if the home is left empty for a long period of time and
there is a chance of frost.
Important
To prevent the radiators and the installation from freezing in
places where that risk exists (e.g. in a garage or an equipment
room), we recommend connecting an outdoor temperature sensor
to the boiler.
If the temperature of the water in the boiler falls too much, the integrated
protection device switches itself on. This device functions as follows:
