Inspection and maintenance
NOTICE
Boiler damage through a lack of, or unsatisfactory, cleaning and
inspection or maintenance!
▶ Have the heating system inspected at least once a year, and have any
necessary maintenance or cleaning work carried out.
▶ Clean the boiler at least every 2 years. We recommend annual
cleaning.
▶ Check and clean the condensate pipes and siphon annually.
▶ Carry out any maintenance immediately to avoid any damage to the
system.
▶ Remedy all faults immediately.
Heating systems must be serviced regularly for the following reasons:
• to achieve a high level of efficiency and to operate the heating system
economically (low fuel consumption),
• to achieve a high level of operational safety and reliability,
• to maintain the cleanest possible combustion,
• to ensure safe and reliable operation and a long service life.
Maintenance work must only be carried out by approved contractors.
Use only original spare parts. The results of the inspection must be
recorded in the inspection and maintenance protocol.
Offer your customer an annual maintenance and inspection contract,
which is based on actual requirements. You can check in the inspection
and maintenance protocols which activities must be included in a
maintenance contract ( Chapter 17.7).
Refer to the spare parts catalogue when ordering spare parts.
We recommend the service set for the burner maintenance.
