Operation
1.
After having reached of heating water temperature, modify the combustion air supply. It is necessary to adjust the primary air throttle valve
and fit it so that the throttle valve of the stocking door was half-closed to 30 - 45 mm depending on specific properties of the fuel.
2.
Depending on the needs in heat and burning intensity, it is necessary to repeatedly add fuel during boiler operation. Add fuel on the
glowing layer with a thickness of about 15 cm. Before adding fuel, perform manual grating the firewood from up through the stocking door.
Before adding fuel, release the orifice of the hole in the bottom part of the combustion chamber lining so that it was possible to smoothly
burning of fuel.
3.
The ash-pan door has to be permanently closed during operation.
4.
Where necessary, empty ash-pan (it is necessary to use gloves).

Maintenance
1.
Check and where appropriate remove ash from the ash-pan, because a filled up ash-pan prevent from correct division of the combustion
air under the fuel and causes non-uniform heating the fuel on the grate. All fuel remnants in the heating chamber and in the combustion
output hole in the lining before each new kindling. For the combustion chamber lining, we recommend that you once-a-month push out its
upper front part (6), middle front part (4) (see Fig. No. 16) and perform cleaning of the space of the combustion chamber. Ash has to be put
in non-flammable vessels with a cover.
Use protective equipment while working
and be particular about personal safety.
2.
With using a brush, once a month clean up walls inside the heating chamber, boiler flues, and chimney pot (cooled boiler, when its
temperature does not exceed 40
°
C). A cleaning cover in the bottom part of the chimney pot serves for the removal ash from it. To demount
the cleaning cover, push and slightly rotate the screw in its bottom part.
After having cleaned-up the chimney pot, mount back the
cleaning cover and be particular about tightness of the cleaning cover with the chimney pot.
3.
As far as during the use of fuels with higher generation of gas, a tar deposit is sedimented on the walls of the combustion space, remove it
by a scraper or with help of burning with help of dry hardwood which operating the boiler at the maximum operational temperature.
4.
After having finished the heating season, clean up the space behind the throttle valve of tertiary air supply, treat pivots of all doors.
5.
Cracks caused by tensioning or light corrosion of the fire-resistant lining are caused by thermal fluctuations and temperature above
1000 °C in the combustion chamber. But what is decisive for the functionality of the device is shape stability of the structural parts. Cracks
do not affect functionality and they can be considered, the same as in case of tiled stove, to be normal.
6.
In the case of impurities on covering parts and control elements, remove them with a soft wet cloth. We recommend slight cleaning agents
without dissolution reagents. Dissolution reagents such as alcohol, petrol or solvents cannot be used because they can damage the device
surface.
7.
We recommend that you clean up the glazing of the throttle valve of the stocking door more frequently and not to allow creation of a too
thick layer of deposits. We recommend that you use preparations for the cleaning-up of glasses of the hearths and stoves. While cleaning,
follow the manufacturer's manual for the cleaning preparation.
8.
We recommend that you clean up the heating system filter after having performed a heating test and consequently before beginning of the
heating season.
