8 Heating system inspection and maintenance

When carrying out maintenance work, observe:

B Always check that the heating system is working

properly after carrying out any maintenance work.

8.1 Why is regular maintenance

important?

Heating systems must be serviced regularly for the

following reasons:

• to maintain a high level of efficiency and to operate the

system economically (low fuel consumption)

• to achieve a high level of operational safety

• to maintain the cleanest possible combustion

• to ensure reliable operation and a 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. Maintenance must

be carried out once a year. The results of the inspection

must be recorded in the maintenance log (Æ page 44).

8.2 Checking the flue system including

the combustion air supply, inlet and

outlet air openings

Check the venting system, including the combustion air,

inlet and outlet openings. All faults must be repaired

immediately. Make sure that the combustion air supply

and the inlets and outlets are not blocked at any point.

8.3 Inspection of the boiler and burner

B Perform a visual inspection of the boiler and burner for

external contamination.

B If contamination is found, clean the boiler and burner.

DANGER: Risk of fatal injury from electric

shock!

B When carrying out servicing work, label all

connection cables before disconnecting

them.

B If cables are connected incorrectly, the

system may not operate correctly with

possibly dangerous consequences.

Spare parts can be ordered from Buderus

using the parts list.
