Safety instructions
For your safety
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 materi-
als 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
humidity levels (e.g. through
continuous drying of washing).
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 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.
