Installation, commissioning, inspection, maintenance and repairs

Before working on the appliance/heating system, isolate it from the
power supply (e.g. by removing a separate fuse or by means of a
mains isolator) and safeguard against unauthorised reconnection.
Repairing components that fulfil a safety function can compromise
the safe operation of the system.
For replacements, use only original spare parts supplied or
