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.
1. Put the boiler in frost protection mode. The standby function will be
deactivated.
The boiler will then only start up to protect itself from frost.
Note
To prevent the radiators and the installation from freezing in pla
ces where that risk exists (e.g. in a garage or an equipment room),
we recommend the connection of an outside 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:
If the water temperature is lower than 7°C, the circulation pump starts
up.
If the water temperature is lower than 4°C, the boiler starts up.
If the water temperature is higher than 10°C, the boiler shuts down and
the circulation pump continues to run for a short time.
