OPERATING PRINCIPLE

The high combustion quality is guaranteed by an electronic 

microprocessor that regulates and optimises the fuel inlet (6 

mm pellet) that, falling from the main tank, flows into a worm 

screw auger, fed by an electric gearmotor (controlled by the same 

P.C.B.) which, according to its speed, makes more or less pellets 

arrive inside the combustion chamber.

The P.C.B. also controls an inverter for fan operation for the 

expulsion of the flue gas, also creating the right negative pressure 

to draw the correct amount of inlet combustion air from the 

room (where the boiler is located).

With normal combustion, the flame must have a tapered, com-

pact shape and be “lively” with tips that are mainly vertical or 

pressed against the back of the furnace. 

The power supplied by the boiler is automatically modulated, 

depending on the heat requested by the P.C.B.. 

The ability to modulate the power avoids continuous switching 

on and off of the boiler, thus maintaining very high efficiency.

By falling, the pellet arrives in the cast iron crucible where, inside 

the carbon steel chamber (resistant to very high temperatures) 

the actual combustion takes place. 

At first ignition or re-ignition after a switch-off for reaching the 

temperature, there is an incandescent electrode which allows to 

fully automatically ignite the flame.

The electrode resistance, located under the crucible, heats the 

combustion air at a very high temperature (hairdryer effect) 

which in turn, ignites the pellet in the brazier itself.

The hot flue gas produced directly by combustion are directed 

towards a row of 10 heat exchange pipes (smoke pipes) with the 

system water (1st round of smoke), made to move by a very low 

electric consumption circulator located on the boiler return.

The hot flue gas meets a vermiculite cover and is channelled 

along the other 6 pipes located on the back of the boiler, giving 

water the additional heat present in the flue gas before their 

expulsion (2nd round of smoke), by means of the fan.

There are turbulators inside the smoke ducts that are manually 

operated via a special lever, to clean the heat exchanger surfaces, 

as well as ensure and maintain an optimal heat exchange.
