Before working on the equipment/
heating system, isolate the power
supply (e.g. by removing a separate
mains fuse or by means of a mains
isolator) and safeguard against
unauthorised reconnection.
When using gas as fuel, also close
the main gas shut-off valve and safe-
guard against unauthorised reopen-
ing.
Repairing components which fulfil a
safety function can compromise the
safe operation of your heating sys-
tem.
For replacements, use only original
spare parts supplied or approved by
Viessmann.
Dispose after installation.
