8.1 Generality
The grid's firebox and the fumes pipes of the generator must be periodically cleared from
solid fuel residues (ash).
The maintenance of fumes pipes cleared by ash guarantees draught efficiency and,
therefore, greater yield of the heat generator.
Tab. 8.2
lists the cleaning operations in
chronological order.
ATTENTION!!
BEFORE CLEANING, DISCONNECT THE ELECTRIC ENERGY
FROM THE GENERATOR BY INTERVENING ON THE MAIN SWITCH
AND ENSURE THAT THE RESIDUE FUEL INSIDE THE FIREBOX IS
OFF AND HAS COOLED DOWN
