In case of fire
Danger
Fire presents a risk of burns and explosion.
■Shut down the heating system.
■Use a tested fire extinguisher, class ABC.
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 messages several
times in quick succession. Inform your heating
contractor so the cause can be analysed 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 carbon 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/pipework routing, cladding
or partitions).
Danger
Easily flammable liquids and materials (e.g.
naphtha, solvents, cleaning agents, paints or
paper) can cause deflagration and fire.
Never store or use such materials in the installa-
tion 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, sol-
vents 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 out-
side (cooker hoods, extractors, air conditioning units,
etc.) can create vacuum pressure. If the boiler is oper-
ated 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 poisoning due to
reverse flow of the flue gas.
Take suitable steps to ensure an adequate sup-
ply 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 replacement work carried
out exclusively by qualified contractors.

Changing the heating curve
■If the room temperature does not meet your require-
ments for a prolonged period of time you can alter
the heating characteristics.
■You influence the heating characteristics by chang-
ing the slope and level of the heating curve. For
more information regarding the heating curve, see
page 21.
■Please observe the modified heating characteristics
over several days (if possible, wait for a major
change in the weather) before making further adjust-
ments.
Changing slope and level
For assistance, use the following table.
