Operation
1. After having achieved the heating water temperature regulate the combustion air inlet. Power control is
executed by the suffocating throttle that regulates secondary air inlet under the grate by means of the damper
or by the adjusting screw of the suffocating throttle itself. Adjust the regulator so that the ash door choke is
nearly closed at the moment of achieving the required heating water temperature (see a separate Operating
Manual of Damper).
2. As need may be during the operation, fuel up the boiler again (hot layer suitable for further fuel stoking is min.
15 cm). Stoke in the way making sure that the fuel layer is equally high along the whole depth of the boiler.
ATTENTION! Prior opening of the stoking door it is necessary to open the smoke adapter partition
with use of the smoke control pull rod.
3. According to Table no. 6, slightly open the rosette of stocking door for inlet of primary air.
4. The rosette in the back part of the boiler must stay closed. In a case of smoke coming out of the chimney,
slightly open the rosette. Inlet of tertiary air in the front part of the boiler is controlled by means of a removable
cover fixed to the small ash pan. This small ash pan must be completely closed and pressed to the front
section in order that unrequired air was sucked.
Important notice!
The dark smoke from the chimney signals not fully closed partition of the smoke adapter or a lack of
tertiary air. A large volume of tertiary air results in cooling of flue gases and thereby reducing the
efficiency of the boiler. Full closure of stoking door rosette can also cause dark smoke from the
chimney and boiler tarring.
5. At the transition to the night top-fed stove damped operation the grate must be cleaned and freshly stoked fuel
must flare. The rosette of stoking door is also kept ajar the draught controller in this case can be unhung (the
choke completely closed). Close the choke of ash pan door.
6. The morning re-putting into operation make by opening the ash door choke, together with poking up the grate
after the ash door opening.
7. The ash door must be closed during the boiler operation.
8. If necessary, clean the ash pan, and the small ash pan with removable cover (the gloves needed).
