For your safety
!
Please note
Incorrect ambient conditions can
lead to heating system damage
and can put safe operation at
risk.
Extractors
The operation of appliances that extract
air to the outside (cooker hoods, extrac-
tors, air conditioning units, etc.) can
create negative pressure. If the boiler is
operated at the same time, this can
lead to a reverse flow of flue gas.
Auxiliary components, spare and wearing parts
!
Please note
Components not tested with the
heating system may damage the
system or affect its function.

Safety instructions
■ 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
humidity levels (e.g. through
continuous drying of washing).
Danger
The simultaneous operation of
the boiler and appliances that
extract air to the outside can
result in life threatening poison-
ing due to a reverse flow of flue
gas.
Take suitable steps to ensure an
adequate supply of combustion
air. If necessary, contact your
heating contractor.
Have all installation or replace-
ment work carried out exclu-
sively by qualified contractors.
