Shutting down the heating system

Caution: Risk of system damage due to
freezing.
If the heating system has been switched off,
it may freeze up at sub-zero temperatures.
V Protect the heating system from freezing
when there is a danger of frost. To do so,
drain the water out of the heating system
from its lowest point. When doing so, the
vent at the highest point of the system
must be open.
