31. Boiler cleaning and ash removal
The burner and the boiler must be cleaned regularly and thoroughly once every 1 to 30 days
depending on the quality of pellets and the output setting.
Fly-ash and dirt accumulated in the com-
bustion chamber of the burner and boiler considerably reduce the service life and output.
Do the regular cleaning of the boiler in such a way that you first let the burner burn out (switch off
pellet burner switch). Open cleaning (filling) door of the boiler clean the combustion chamber of the
burner, incl. the air openings in the chamber with the provided poker. If the combustion chamber of the
burner is heavily soiled, remove it for cleaning.
Then sweep the ashes down through the grill into the lower area (ash-pan). Remove the ashes. Thor-
oughly once every 14 dasy - 2 mounts clean the tube heat exchanger (placed above the combustion chamber)
regularly by the supplied brush. With the boiler types D20P, D30P, D40P, D50P carry out the cleaning with
the brush inserted in the exchanger (the brush also serves as an air-break valve). At least two time a year
check and sweep upper heatproof shaped piece – upper spherical chamber (caution - fragile). If the boiler
operates with a pellet burner, also clean the cinder from the burner‘s burn-off chamber. With the boiler types
(the D20P, D30P, D40P, D50P models), clean the ventilator‘s rotating wheel which is placed on the extraction
fan (in the rear section of the boiler) at least once a year. The cleaning and ash-removing interval depends
on the fuel quality, heating intensity, chimney draught and other conditions. At least once a year remove the
burner and thoroughly clean space where pallets fall down into the burner and where the pellets burn out.

- By D20P, D30P, D40P, D50P we recommend switch on the extraction ventilator for
cleaning.
