Inspection and maintenance
Heating systems should be regularly serviced 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 reliability,
• to maintain the cleanest possible combustion,
• to ensure reliable operation and long service life.
Maintenance must only be carried out by qualified service
engineers. If parts are replaced, use exclusively Buderus-
approved components. A service must be carried out
once a year. The results of the services must be recorded
in the inspection and maintenance report.
Offer your customer an annual contract covering
inspection and demand-dependent service. The work that
needs to be included in a maintenance contract is
detailed in the inspection and maintenance reports
(

Chapter 9.14, page 52).
