5.3.3 Shutting down the installation

If the central heating system is not used for a long period of time, we rec­
ommend switching off the boiler.
1. Switch the On/Off switch to Off.
2. Cut the electrical power to the boiler.
3. Close the oil inlet.
4. Have the boiler and the chimney carefully swept.
5. Close the door of the boiler to prevent air circulating inside it.
6. Remove the pipe connecting the boiler to the chimney and plug the
flue gas nozzle.
7. Keep the area frost-free.
If the central heating system is not in use and there is a risk of frost, we
recommend activating the boiler's antifreeze protection function.
Caution
The frost protection does not work if the boiler is switched off.
Caution
The integrated protection system only protects the boiler, not the
heating installation
Caution
If the home is unoccupied for a long period and there is a risk of
frost, drain the boiler and the heating system.
