flames and sparks. Do not
switch lights or electrical appli-
ances on or off.

ply utility and your local heating
contractor from outside the

place (outside the building).
If you smell flue gas
Danger
Flue gas can lead to life threat-
ening poisoning.
■ Shut down the heating system.
■ Ventilate the installation site.
■ Close all doors in the living
space.

What to do if the heating system
develops a fault
Danger
Fault messages indicate faults in
the heating system. If faults are
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.
Installation room requirements
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
materials (e.g. petrol, solvents,
cleaning agents, paints or paper)
can cause deflagration and fire.
Never store or use such materials
in the installation room or in direct
proximity to the heating system.
!Please note
Incorrect ambient conditions can
lead to heating system damage
and can put safe operation at
risk.
■ Ensure ambient temperatures
are above 0 °C and below
35 °C.
■ Prevent air contamination by
halogenated hydrocarbons
(e.g. as contained in paints,
solvents or cleaning fluids) and
excessive dust (e.g. through
grinding/polishing work).
■ Avoid continuously high humid-
ity levels (e.g. through continu-
ous drying of washing).
Extractors
The operation of appliances that extract
air to the outside (cooker hoods, extrac-
tors, air conditioning units, etc.) can cre-
ate negative 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.
Only allow qualified contractors
to carry out installation or
replacement work.
