7.2 Burning Pot Manual Cleaning
Clean burning pot daily or at every ignition
(fig. 18). If the boiler/thermostove mainte-
nance and ash removal are not performed
regularly, it can cause:
• Poor combustion;
• Glass smoke up;
• Accumulation of ash and unburnt pel-
lets in the burning pot;
• Ash residue depositing on the heat
exchanger and its poor efficiency as
result.

7.3 Automatic Exchanger Cleaning
High thermal exchange remains constant
in time thanks to the patented Ungaro tube
bundle cleaning. The models with Automa-
tic Exchanger Cleaner do not request any
user's intervention.
7.4 Exchanger Manual Cleaning
Remove the butterfly screw, pull and
push intensively several times the grate of
exchanger cleaner (fig. 19). This operation
should be performed each three days.
Regular exchanger cleaning helps
to keep high efficiency of the boiler/
thermostove.
