for this purpose. Were the boiler is extinguished and cooled down, clean the com-
bustion chamber and exhaust ducts through the clean out holes and inspection
doors on the front wall of the boiler. To do this, remove the cover of the top clean
out. The access for cleaning of vertical partitions of the exchanger is possible after
removing the gas chamber cover. Before cleaning the exchanger remove the gas
turbulator through top clean out hole (Fig. 13). Using the available tools, clean the
surface from dust/soot.

Carefully clean the ceramic panels inside the combustion chamber. After thoro-
ugh cleaning of the ducts, clean the flue pipe trough side clean outs. After cleaning
these openings must be tightly closed. Remove periodically precipitated dust/ash
through the door of side clean out and burner air box clean out. The boiler is equip-
ped with the ash-box drawer located in the bottom part of the device, and it must be
regularly emptied of the burning process residues (ash, dust, slag).
At the factory, the boiler was equipped with a set of ceramic sealant (see inspec-
tion/clean our doors/holes). Regular inspection of the sealant condition is recommen-
ded, and its replacement when any wear is discovered.
Inside the furnace special attention should be paid to the periodic cleaning of ho-
les in the automatic firebox and on its sides. These operations should be carried out
after the boiler turns off and when furnace cools down to allow safe cleaning. Access
to the furnace is possible after removing the cover (upper section) using available
tools (e.g. poker), using the mounting bracket on the housing. The housing removal
must be carried out carefully so as not to damage the refractory ceramic material
shape. After removing the housing also clean the surface of ceramic shape from the
residues of biomass combustion (ash, slag). Additionally, an air chamber located
below the furnace should also be cleaned periodically, because ash falling from the
automated furnace plate collects there. Cleaning is done through the air chamber
clean out located under the automatic furnace. After cleaning the furnace, close the
air chamber clean out and refit the housing with the ceramic shape (see figure 7).
