Note
Details identified by the word "Note" con-
tain additional information.
Installation, initial start-up, inspection,
maintenance and repairs must only be
carried out by a competent person (heat-
ing engineer/installation contractor).
Before working on the equipment/heat-
ing system, isolate the power supply
(e.g. by removing a separate mains fuse
or by means of a mains isolator) and
safeguard against unauthorised recon-
nection.
When using gas as fuel, also close the
main gas shut-off valve and safeguard
against unauthorised reopening.
Repairing components which fulfil a
safety function can compromise the safe
operation of your heating system.
For replacements, use only original
spare parts supplied or approved by
