Safety instructions
For your safety
If there is a fire
Danger
Fire presents a risk of burns and
explosion.
What to do if water escapes from the appliance
Danger
If water escapes from the appli-
ance there is a risk of electrocu-
tion.
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.
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).

■ Shut down the heating sys-
tem.
■ Close the shut-off valves in
the fuel supply lines.
■ Use a tested fire extinguisher,
class ABC.
■ Switch OFF the heating sys-
tem at the external isolator
(e.g. fuse box, domestic distri-
bution board).
■ Notify your heating contractor.
Do not acknowledge fault mes-
sages several times in quick
succession. Inform your heating
contractor so the cause can be
analysed and the fault rectified.
Danger
Easily flammable liquids and
materials (e.g. naphtha/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.
