burner switch (black) /18/). Open the cleaning door and clean the combustion chamber of the burner
including the air openings in the chamber with the provided poker. If the combustion chamber of the
burner is heavily soiled, remove it for cleaning and knock it out.
Remove the ash from the whole cleaning chamber with the half-round ash pan (accessory of the
boiler). Insert the ash pan into the boiler to the end, push the ash into the ashtray by thrusting it into
the rear wall and remove the ashtray. Never leave the ash pan in the boiler!
Use the handle on the cleaning lid in the rear part of the boiler hidden under the cover for operation
cleaning of the tube exchanger and decelerators. By repeated pulling out and releasing of the handle
the ash is knocked out from the decelerators and the tube plate walls are scraped off.
To thoroughly clean the tube exchanger, firstly remove the decelerators from the tube plate
together with the lid and clean it with the provided brush. Also, do not forget to clean the back smoke
channel and scrape the walls of the combustion chamber of the boiler with the provided poker or
brush. Put everything in the original condition after the cleaning. The ash removal from the lower
chamber is always performed after operation cleaning of the tube exchanger since the dust falls to the
lower chamber when cleaning the tube plate so there are no other cleaning opening necessary in the
boiler!
The interval of the cleaning and ash removal depends on the fuel quality, heating intensity,
chimney draught and other circumstances, and it must be observed therefore.
At least once a year clean (sweep) the rotating wheel of the draught fan and remove the pellet
burner and clean it completely – see the instructions for use of the burner.
NOTE
– Regular and thorough cleaning is important to ensure continuous output and
service life of the boiler. If insufficiently cleaned, the boiler and the burner can be damages
– and the guarantee will expire.
INFO
– The pellet burner ATMOS A25 can be equipped with pneumatic cleaning of the
combustion chamber. It will be appreciated especially by those using lower quality pellets
forming certain agglomerates. See accessories for ATMOS boilers.
