LEONARDO
is a combustion safety and control system which allows optimal performance 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 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
type of pellets and automatically djust the ow moment by moment to ensure the required level of
combustion.
