ignite them. Close the feeding door and open the third door to provide air. When the
woods are on fire feed the boiler with woods. During feeding insert woods with
smallest diameter on the bottom and the biggest on the top. Ensure that the woods
are on fire and close tightly the doors of the boiler. Close the dumber pushing the
lever and start the ventilator. Ensure that the doors are closed and there not leave
smoke or sparks.
5.2. Combustion settings
The flame should have suitable dimensions and cover the combustion chamber. The
effective operation of the boiler depends largely on the settings of primary and
secondary air.
If the primary air is excessive, much ash will fall into the combustion chamber. The
flame will be very strong and fast and make noise while wood consumption would be
high.
If the primary air is not enough then the flame will be low and slow and moving by air
currents and will be attracted by the chimney. It will not cover the entire surface of the
chamber, while the production of ash will be small.
If the secondary air is excessive then the flame is small and blue.
If the secondary air is enough then the flame would be great, embracing the entire
combustion chamber and will be red and opaque.
5.3. Maintenance
Daily maintenance
On a daily basis you need to check the integrity of the boiler room and the correct
operation of the boiler. Check that the pressure in the network is correct and that all
safety devices are in good condition and functioning properly. The boiler should be
cleaned daily by the combustion residues (ash and unburned residues). Clean both
upper chamber and combustion chamber. Clean walls and ceramic plate on the
upper chamber and throw the ash in the combustion chamber. Remove the ash from
the combustion chamber. CAUTION! The ash may contain hot residues which may
cause fire in the final disposal. Finally, check the integrity of the ceramic plates.
Weekly maintenance
Weekly cleaning of the boiler includes thorough cleaning of the combustion chamber
and the upper chamber. Open the dumber and then open the feeding door, wipe the
ash from the chamber and throw it to the combustion chamber. With a brush clean
ceramic plate lying between the two chambers. Ensure that ashes do not include hot
residues before its disposal. Use a scraper for cleaning the walls of the chambers of
any deposits. If ashes have accumulated underneath the ceramic plate in the
combustion chamber, remove it and clean the chamber. Refit the ceramic in the
chamber with special attention to proper placement. Before you clean, leave the
boiler switched off for at least one or two hours to cool. In continuous operation, it is
recommended to be cleaned once every 4 days.
Monthly maintenance
During the monthly cleaning clean the smoke chamber. The smoke chamber has
openings for cleaning. Unscrew the screws and clean the deposits of ash. With a
scraper remove smoke and ash from the walls of the smoke chamber. Collect them
of the side opening. After the cleaning, close the openings tight. Check the tightness
of the openings and the condition of the sealing cord. Replace it if it is necessary.
