CAUTION: Risk of system damage due to freezing!
The heating system can freeze up in cold weather if it is
shut down.
▶ 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.

Heating system inspection

Heating systems should be regularly maintained for the following
reasons:
• to achieve a high level of efficiency and to operate the system
economically (low fuel consumption),
• to achieve a high level of operational safety and reliability,
• to maintain the cleanest possible combustion,
• to ensure reliable operation and long service life.
Maintenance work may only be carried out by a qualified service
technician. If parts are replaced, only Buderus-approved
components may be used. A service must be carried out once a year.
The results of the services must be recorded in the servicing and
maintenance log.
Spare parts can be ordered from Buderus with the aid of
the parts list.
