risk of material losses and envi-
ronmental pollution.
Note
Details identified by the word "Note"
contain additional information.
Installation, initial start-up, inspection,
maintenance and repairs must only be
carried out by a competent person
(heating engineer/installation contrac-
tor).
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
Viessmann.
