8 Heating system servicing
8.1 Why is regular maintenance important?
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 reliability,
• to maintain the cleanest possible combustion,
• to ensure reliable operation and long service life.
Servicing 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.
8.2 Preparing the boiler for servicing
▶ Shut down the heating system. ( Chapter 7.1, page 34)
▶ Remove the burner door panel or the burner hood from the boiler.
( Chapter 3.1, page 12)
▶ Disconnect electrical supply to burner.
Spare parts can be ordered from Buderus using the parts
list.
DANGER: Risk of death from electric shock.
▶ Before working on the boiler and prior to opening
control panel:
shut down the power supply by turning off the
emergency shut-off switch or disengaging the
heating system circuit breaker, and prevent from
accidental reactivation.
