The cleaning procedure of the ash should be performed with a specialized tool –
a metal brush, by pushing and pulling the brush upwards and downwards. After
the ash has been brushed away, the collected ash residue should be cleaned by
opening the lower lid and to scrape out the ash out of the lower section of the
convective heat exchanger of the boiler.

Draw out the turbulizers (upwards). The
practice shows that these elements could be
stuck due to ash deposition – it is necessary
to make careful handling and vertical lifting
of these elements
