Safety instructions explained
Danger
This symbol warns against the
risk of injury.
!Please note
This symbol warns against the
risk of material losses and envi-
ronmental pollution.
Note
Details identified by the word "Note" con-
tain additional information.
Target group
These instructions are exclusively
designed for qualified personnel.
■ Work on gas appliances must only be
carried out by a qualified gas fitter.
■ Work on electrical equipment must
only be carried out by a qualified elec-
trician.
Regulations
Observe the following when working on
this system
■ all legal instructions regarding the pre-
vention of accidents,
■ all legal instructions regarding envi-
ronmental protection,
■ the Code of Practice of relevant trade
associations,
■ all current safety regulations as
defined by DIN, EN, DVGW, TRGI,
TRF, VDE and all locally applicable
standards.
Working on the system
■ Isolate the system from the power sup-
ply and check that it is no longer 'live',
e.g. by removing a separate fuse or by
means of a mains isolator.
■ Safeguard the system against unau-
thorised reconnection.
■ When using gas as fuel, also close the
main gas shut-off valve and safeguard
against unauthorised reopening.

When connecting external switching contacts or components to the low voltage circuit
of the control unit, please observe the safety requirements of protection class II, i.e.
8.0 mm air gap/creep path or 2.0 mm insulation thickness towards 'live' compo-
nents.
For all on-site components (incl. PC/laptops), ensure safe electrical separation to
EN 60 335 or IEC 65.
!Please note
Electronic modules can be dam-
aged by electrostatic dis-
charges.
Before beginning work, touch
earthed objects, such as heating
or water pipes, to discharge static
loads.
Note
■ Only route cables and capillaries on
the r.h. or l.h. side of the boiler under-
neath the casing panels, and secure
these with cable ties.
■ Ensure that subsequent maintenance
work is not hindered by cables.
■ Never allow cables/leads to come into
contact with motors or hot boiler com-
ponents.
