Turn off the boiler gas tap.
Warning - Drain boiler
If there is a chance that the boiler and system can be effected by

carried out. If the central heating system is not used for a long time
(during the holidays, for instance, or periods of milder weather) it is
advisable to disable the boiler.

Now the boiler will only start working to protect itself against freezing.
With an external frost protection connected, the boiler can also prevent
the central heating system from freezing.
