1.4 Technical description

The stove works exclusively on pellets, providing healthy and safe heat in the room. The stove's automatic control
systems guarantee optimum heat output and complete combustion; there are also safety systems to guarantee safe
operation for the stove parts and for the user.
When correctly installed, the unit works in any outside climatic conditions, and in any case in critical conditions
(strong wind, frost, etc.) the safety systems can cut in, shutting down the stove.
