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
reconnection.
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
