4.3 Stopping the boiler
4.3.1 Switching off
Set the On/Off switch to {.A boiler which is switched off is not protected against frost.
The control panel should always be switched on to take
advantage of the heating pump anti-sticking function
4.3.2 Antifreeze protection
Leave the boiler on standby:
- Turn the boiler thermostat to Min.
- Turn the domestic hot water thermostat to Min.
The pumps start up when the temperature falls below 8°C.
The pumps and the burner start up when the temperature falls below
6°C.
4.3.3 Cleaning the pumps
Leave the boiler on standby:
- Turn the boiler thermostat to Min.
- Turn the domestic hot water thermostat to Min.
The pumps operate for 5 seconds if they have been inactive for more
than 24 hours.
4.3.4 Precautions to take if there is a danger of frost
Heating circuit:
Use a correctly dosed antifreeze to prevent the heating water
freezing. If this cannot be done, drain the system completely. In all
cases, consult the fitter.
Domestic hot water circuit:
Drain the domestic water tank and pipes.
4.3.5 Precautions to take in the event of prolonged shutdown (one year or more)
- Close the gas valve
- The boiler and the chimney must be swept carefully.
- Close the door of the boiler to prevent the internal circulation of air.

4. Operating the appliance
4.4 Restart of the boiler
Initial commissioning must be done by a qualified
professional.
1. Open the gas valve.
2. Set the boiler thermostat to the desired setting.
3. When preparing domestic hot water: Set the DHW thermostat to
the desired setting.
4. Set the On/Off switch to z.
If the flame is not detected, the boiler tries to ignite 4 more times
before going into safety shutdown.
5 Checking and maintenance
Make the following checks at least 1 time a year:
- Safety devices
- Water level
- Checking burner safety
- Checking the gas inlet
Carry out the following maintenance at least 1 time a year:
- Principal exchanger
- Plate exchanger
- Burner
- Cleaning the "cold water" filter
- Cleaning painted surfaces
