INSTALLATION AND OPERATION MANUAL
door and push the handle of the damper 3 (Fig. 1). Press the ventilator knob 4 (Fig. 10) on the front control panel into the
„60-95° C“ position. The ventilator will start and the boiler will continue its firing mode.
If you lack time to stoke the boiler in the two stages mode as described above, then stoke it by one stage. The boiler will operate
as usual. But if there is the possibility to do so, use the two stages mode in order to achieve an even more effective combustion.

While adding firewood into the combustion chamber, during boiler operation or after a load has burned off, keep strictly
to the following procedure:
1. Open the damper of the upper flue 19 by pulling the handle 3 towards yourself (Fig. 1).
2. Switch off the ventilator switch 3 (Fig. 9).
3. Wait at least 20 seconds, allowing the smoke to be removed by draught; then slowly open the upper door.
4. Put the firewood in and close the door tightly.
5. Switch on the ventilator to the 0-60° C position, if the actual water temperature is lower than 60° C.
6. Close the damper of the upper flue 19 by pushing handle 3.
7. Switch the ventilator button to the 60-90° C position, after the actual water temperature has rised over 60° C.
If operated following this order, smoke and carbon monoxide will not enter the room. Water temperature and pressure in
the system are checked by readings of the thermometer-manometer, installed in the heating system.

The status of the boiler firing process can be seen from the indications of the thermometer 2 (Fig. 10). The firing is active if
the temperature of water in the boiler exceeds approximately 60° C. The flame in the boiler can be checked by opening the
door of the lower combustion chamber when the ventilator is on. The visible tongue of flame has to be yellow or yellow-red
and reach the ceramic element; this means the firing is proceeding in an optimal manner.
Do not keep the lower door of the boiler open for extended periods of time during firing: the lower chamber
contains gases which, when escaping into the boiler room in larger amounts, can impair human health.
• cleanInG THe boIleR
Ashes are removed from the boiler every 4-7 days. Open the door of the upper combustion chamber and shovel ashes down to the
lower chamber. Open the door of the lower chamber, take out only ceramic segments 3 (Fig. 2), pour ashes to a metal box. It is not
necessary to take out the triangle ceramic chopper 2 (Fig. 2) at the time of cleaning, ashes underneath it may be raked using scraper.
In any case, strictly follow the established procedure when opening the upper door: open the damper
of the upper flue, then after 20 seconds, open the boiler door.
Clean boiler chambers from tar, pitch and scurf once or twice a month. Clean the boiler when the fuel has been completely
burned and the boiler is cooled down to at least +40°C.
Open the upper cap 15 for cleaning the flue (Fig. 1). Remove the turbulence plates from the flue by hooking them and
pulling them out with the poker, then clean them using a scraper. Clean tar and scurf from combustion chambers and flue
walls using a scraper and metal hog. Clean with the doors of the combustion chambers open. The soot residues falling down
from the flue walls during the cleaning process are raked out of the boiler through the lower opening of the combustion
chamber 25 (Fig. 1), pulling them outwards. When finished, place the turbulence plates back and close the cleaning cap.
