not rectified, they can have life
threatening consequences.
Do not acknowledge fault mes-
sages several times in quick suc-
cession. Inform your heating con-
tractor so the cause can be ana-
lysed and the fault rectified.
Conditions for siting
Danger
Sealed vents result in a lack of
combustion air. This leads to
incomplete combustion and the
formation of life threatening car-
bon monoxide.
Never cover or close existing
vents.
Do not make any subsequent
modifications to the building
characteristics that could affect
safe operation (e.g. cable/pipe-
work routing, cladding or parti-
tions).
Danger
Easily flammable liquids and

Extractors
The operation of appliances that extract
air to the outside (cooker hoods, extrac-
tors, air conditioning units, etc.) can cre-
ate vacuum pressure. If the boiler is
operated at the same time, this can lead
to reverse flow of the flue gas.
Danger
The simultaneous operation of
the boiler and appliances that
extract air to the outside can
result in life threatening poison-
ing due to reverse flow of the flue
gas.
Take suitable steps to ensure an
adequate supply of combustion
air. If necessary, contact your
heating contractor.
Auxiliary components, spare and
wearing parts
!Please note
Components not tested with the
heating system may damage the
system or affect its function.
Have all installation or replace-
ment work carried out exclusively
by qualified contractors.

The appliance is only intended to be
installed and operated in sealed unven-
ted heating systems that comply with
EN 12828, with due attention paid to the
associated installation, service and
operating instructions. It is only designed
for the heating of heating water that is of
potable water quality.
Intended use presupposes that a fixed
installation in conjunction with permissi-
ble, system-specific components has
been carried out.
Commercial or industrial usage for a pur-
pose other than heating the building or
DHW shall be deemed inappropriate.
Any usage beyond this must be
approved by the manufacturer in each
individual case.
Incorrect usage or operation of the appli-
ance (e.g. the appliance being operated
for longer periods when open) is prohibi-
ted and will result in an exclusion of lia-
bility. Incorrect usage also occurs if the
components in the heating system are
modified from their intended use (e.g. if
the flue gas and ventilation air paths are
sealed) or if other fuels than those inten-
ded for this appliance are used.
Commissioning
The commissioning and matching up of
the control unit to local conditions and
the structural characteristics of the build-
ing must be carried out by your heating
contractor.
Service instructions
As the user of new combustion equip-
ment, you may be obliged to notify your
local flue gas inspector of the installation
[check local regulations]. Your local flue
gas inspector (where applicable) will
also provide you with information on
additional activities concerning your
combustion equipment (such as regular
testing, cleaning, etc.).

The appendix contains a chapter entitled
"Terminology" to provide you with a bet-
ter understanding of the functions of your
boiler.
Energy saving tips
Use the adjustment options offered by
your boiler control unit:
■ For central heating, select the operat-
ing program that meets your current
requirements:
– For short periods of absence (a few
hours e.g. shopping trips), select
"Economy mode" (see page 32).
As long as economy mode is activa-
ted, the room temperature is
reduced.
– If you are going away, select the
"Holiday program" (see
page 33).
The operating program for central
heating is automatically set to
"Standby mode" while the holiday
program is active.
– If, for an extended period, you do not
want to heat the rooms and you do
not require DHW, select the
"Standby mode" operating pro-
gram for the relevant heating circuits
and for DHW.
– See page 24 for the relevant
heating circuits
– See page 35 for DHW heating
■ Never set the DHW cylinder tempera-
ture excessively high (see page 35).
Contact your heating contractor for addi-
tional energy saving functions offered by
the control unit for your boiler.
For recommendations for energy saving,
see page 67.
