Boiler Cleaning - ATTACK AWP 25 Instructions For Use Manual

14. BOILER CLEANING

To ensure the correct boiler operation and the appropriate comfort and life, it is necessary to
clean it regularly.
CAUTION
Always clean the boiler regularly and properly, otherwise it my cause decreased boiler life
or wrong burning. If the boiler is not cleaned regularly and sufficiently, the warranty is not
valid.
The boiler must be cleaned regularly and properly, every 3–5 days, because the ash accumulated
in the feeding chamber or the combustion chamber together with the condensate and tar
significantly decrease the lifetime, output and efficiency of the boiler.When there is more ash,
there is not enough space for fuel burn-out and the holder of the ceramic nozzle could get
damaged and thereby the whole boiler would be damaged. Remove the ash and soot through
the bottom opening. Open the bottom door and clean the bottom space form dirts. The
frequency of cleaning depends on the quality (humidity) of wood and the intensity of heating,
chimney draught and other conditions. We recommend to clean the boiler 1× a week. Do not
take the refractory piece out, when the boiler is being cleaned.
It is necessary to clean the following places in the below mentioned intervals:
 feeding chamber of the gasification part (every 3 days)
 combustion chamber of the gasification part (everytime before loading)
 space under the combustion chamber of the gasification part (everytime before loading)
 removable ash tray of the pellet part (depends on a boiler usage, but at least every 2 weeks).
 burner grate (2× a year)
 pellet chamber (1× a year)
 radial impeller of the ventilator (2× a year)
 air chamber of the vetilator (2× a year)
 pipes of exchanger (1× a year, it is necessary to undo the turbulators)
 integrated pellet tank from the residual pellet powder (depends on the operation, at least 1×
a year)
 filter of the integrated tank (1× a year)
