LEONARDO is a combustion safety and control system which allows optimal performan-
ce in all conditions thanks to two sensors measuring the pressure level in the combustion
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
À
ue (bends, length, shape, diameter, etc..) and
environmental conditions (wind, humidity, atmospheric pressure, installations at high al-
titude, etc.). The standards for installation must be respected. LEONARDO system is also
able to recognise the type of pellets and automatically djust the
À
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 (* *).
