Page 12: Chapter3 The Fuel
Chapter3 THE FUEL Pellets are realised by subjecting wood shavings i.e. the rejects of pure wood (without paint) sawmill, carpenter products and products from other activities connected to working and transforming wood, to very high pressures. This type of fuel is absolutely ecological as no glues are used to hold it together. In fact, the compactness of the pellets is guaranteed through time by a natural substance that is found in wood: lignin. -
Page 13: Chapter4 Safety Devices
Chapter4 SAFETY DEVICES FLUE EXHAUST BREAKAGE If the suction device stops, the electronic board immediately blocks the pellet supply. PELLET FEED MOTOR STOP If the motor reducer stops for any reason, the machine goes into alarm mode and the fumes motor continues to function in order to expel all combustion gas until the minimum cooling level is reached. -

Page 33: Ignition
Chapter7 The boiler you have purchased uses pellet fuel. This type of material is obtained from natural waste from the machining of wood. By means of a special process that does not require the use of any binding agent and additive, the waste is compressed in industrial machinery under high pressure and they become solid wooden pellets. -
