For more detailed information, please contact the DEALER who has performed the fi rst
1st ignition.
LEONARDO
®
is a combustion safety and control system which allows optimal perfor-
mance in all conditions thanks to two sensors measuring the pressure level in the combu-
stion chamber and smoke temperature.
The detection of and subsequent optimisation of these two parameters is continuous in
order to correct operation anomalies in real time.
The LEONARDO
®
system offers constant combustion, automatically regulating the
draft based on the characteristics of the chimney fl ue (bends, length, shape, diameter,
etc..) and environmental conditions (wind, humidity, atmospheric pressure, installations
at high altitude, etc.).
The standards for installation must be respected. LEONARDO
®
system is also able to
recognise the type of pellets and automatically djust the fl ow moment by moment to
ensure the required level of combustion.
FUSE
two fuses are inserted in the so-
cket with switch, located on the back of
the boiler-stove, one of which operational
(*) and the other is held in reserve (* *).
