Inspection and service
8.1
General notes
Offer your customer an annual contract covering inspection and
responsive service. For the work covered by such a contract, see
chapter 8.5 "Inspection and maintenance reports", page 35.
8.2
Preparing the boiler for inspection and maintenance
▶ Shut down the heating system (
chapter 7.1, page 31).
Prior to opening the combustion chamber door:
▶ Check the general condition of the heating system.
▶ Visual inspection and function check of the heating system.
▶ Check all system parts that carry fuel or water for leaks and visible
corrosion.
NOTICE:
System damage due to frost.
When there freezing conditions, the heating system can
freeze up if it is not operational, e.g. because of a fault
shutdown.
▶ When there is a risk of frost, protect your heating
system against freezing.
▶ If your heating system has been shut down for several
days due to a fault shutdown and there is a risk of
frost, drain the heating water at the drain & fill valve.
Also leave the air vent valve at the highest point in the
system open.
NOTICE:
System damage due to frost.
The heating system can freeze as a result of a power
failure or if the power has been switched off.
▶ Check the "Control unit settings" to ensure the system
remains operational (especially when there is a risk of
frost).
Only in emergencies, switch OFF the heating system via
the boiler room MCB/fuse or the heating system
emergency stop switch.
NOTICE:
System damage due to inadequate cleaning
and maintenance.
▶ Carry out cleaning and maintenance at least once a
year. In the course of this work, check the entire
heating system including the neutralising system for
correct function.
▶ Immediately correct all faults to prevent system
damage.
Annual inspection and service are part of the warranty

work on the heating system.
▶ Prior to opening the heating system: Isolate the
heating system from the mains power supply via the
heating system emergency stop switch or the
corresponding domestic MCB/fuse.
▶ Secure the power supply against unintentional
reconnection.
DANGER:
Risk to life through explosion of flammable
gasses!
▶ Work on gas components must only be carried out by
qualified and authorised gas engineers.
If gas lines have to be detached from the gas burner, the
combustion chamber door may only be opened by a
qualified contractor.
