Boiler Cleaning - ATTACK SLX20 Instructions For Use Manual

8.1 BOILER CLEANING

It is necessary to clean the boiler regularly to ensure correct operation and required comfort and
life-time.
NOTICE: Always perform boiler cleaning regularly and thoroughly, otherwise it may
leads to the life-time decrease or incorrect combustion! Warranty is not valid if the boiler
is not cleaned regularly and sufficiently.
It is necessary to perform cleaning regularly and thoroughly every 3-5 days, because sedimenta-
tion, condensates and tar in the combustion chamber significantly lower life-time, output and
efficiency of the boiler. If there is a higher amount of ash, fuel does not have sufficient space for
burning and it might lead to the damage of holder of ceramic nozzle and because of that, to the
damage of whole boiler. Perform boiler cleaning by starting the fan at first, opening feeding
door and brushing all dirt down to the lower part. Leave long pieces of unburned fuel in the
loading chamber. Move several times with the lever of exchanger cleaning, on the left side of the
boiler. Open the lower cleaning hole and take the ash and soots out. Open lower door and clean
lower part of dirt. Cleaning interval depends on fuel quality (moisture) and heating intensity,
chimney draught and other factors. We recommend to clean the boiler once a week. Do not pull
the fireproof parts out of the boiler during cleaning.
NOTICE: Regular and proper cleaning is important for ensuring permanent output and
life-time of the boiler. Boiler might get damaged if it is not cleaned properly and war-
ranty is not valid.
