BOILER FUNCTIONS
The boiler electronically controls pellet combustion and water distribution to utilities.
Pellets are taken from the storage tank by the gear motor driven auger and transported directly to the combustion basket by a second
auger driven by another gear motor.
The tank on the top of the bioler is filled through the lid, at the top of the cladding, and equipped with a safety micro switch to permit
access to the container chute. Pellets must be placed in the tank with a shovel and not directly poured from the bag.
Ignition is through air aspirated into the crucible by the centrifuge fan and brought to high temperature by heating an electrical resistance.
The fireplace is made up of a special steel heat exchanger, closed at the front by a ceramic glass door. The exchanger has a gas pass
that allows it to be defined as a flue stove, whose constructions fully exploits the heat produced by combustion.
The quantity of fuel, the feeding of comburent air and the extraction of fumes are regulated with an electronic card in order to obtain a
highly efficient combustion.
All data typing for operation management has to be carried out through the apposite control panel (see
CHAP. 08.2 – USER DISPLAY).
As far as cleaning and/or maintenance operations are concerned, it may be necessary to open the outer boiler door or the combustion
chamber door or disassemble the boiler cladding side panels; in this case proceed as described at
CHAP. 08.6 – ORDINARY
MAINTENANCE
.
It is important to handle very carefully the cladding components, whether they are glazed, polished or painted, as they may be prone to
scratches and dents during either handling or assembly.
Pellet combustion products must only be used with the combustion chamber door closed. NEVER open it during
operations. .
