COKE

The most suitable fuel is coke of 24-60mm grain-size.

WOOD

To reach the nominal output it is necessary to keep the max. 20% moisture content of wood

Fuel must be stored in dry place..

Cleaning of the grid is made so as not to let burning fuel drop down to the ash collection basin. do popolníka

BLACK COAL

The most proper fuel is black coal of 24-60mm grain-size.

How to start fire

1. Check the amount of water in the heating system on the thermomanometer.

2. Open boiler fittings between the boiler and heating system.

3. Clean the grid, ash collection basin, flues, and walls of the boiler. ( after cleaning the boiler check the tightness of the cowl )

4. Spread wood through the ash port and chamber port along all the lenght on the cleaned grid.

5. Flue flap in the cowl adjust into the position of open and close the load port..

6. Inflame wood thorugh open ash port and chamber port.

7. Close the chamber port and ash port and open the fuel cut-off slide fully.

8. On burning wood load a thin layer of basic fuel..

9. After inflaming it, load other dose of fuel up to the bottom edge of a load port and arrange the fuel into an even layer.

10. As soon as fuel gets deep red glare, open a little the air disk of secondary air inlet on the load port by means of a tool.

11.After the flame turns yellow, close the air disk of secondary air.

Operation

1.After reaching the temperature of heating water adjust the inlet of combustion air. The boiler output is regulated by the change of

draught with the help the flue flap in the cowl. A slight output regulation is carried out with a fuel cut-off slide that regulates the air

inlet under the grid either manually or with a draught regulator. Adjust the draught regulator so that the cut-off slide in the ash port

was almost closed in the moment when the required temperature is reached.

2. Reloading the boiler during operation depends on the need for heat and burning intensity. When realoading, the layser of fule must

be equally thick.

3. When using coke, black coal, wood, it is necessary to open partially the air rose of secondary air inlet in the loading port during all

the time of inflamation of reloaded fuel. (The air rose must be controlled by a tool due to the surface temperature.)

4.When starting the night operation, clean the grid, let the reloaded fuel burn thoroughly and then decrease the boiler output by

cutting off the draught by the cut-off slide and turning down the air rose of the secondary air inlet. The level of opening of the cut-off

slide and air rose must be tested and it is necessary to prevent escape of flue gases into the boiler room. The draught regulator should

be turned off (close the cut-off slide)..

5. To restart operation of the boiler in the morning, open the cut-off slide and air rose and rake the grid after opening the ash port.

6. The ash port must be permanently closed during the operation of the boiler.

7. If necessary, deplenish the ash collection basin (use protective gloves).

Dew formation and tarring of the boiler

After first burnings in a cold boiler water condenses on the walls and flows down into the ash collection space which can make the

impression that the boiler is leaking. This dew disappears after setting ashes down on the inner walls of the boiler. When the boiler

runs with low temperature of water under 65°C and with wet wood, water condensates in flue gases, condensate flows down cold

walls of the boiler. Heating with low temperatures is also not suitable for the service life of the chimney body.

Tarring of the boiler occurs under similar conditions (low output, low temperature) furthermore during insufficient burning (lack of

combustion air) Tar from the boiler can be removed best under the minimum temperature of 90°C in the boiler. This temperature can

be reached fast by turning off the radiator. To prevent dew formation and tarring of the boiler, it is recommended to run the boiler with

the temperature over 65°C and choose the boiler according to the needed output of the heating system.

Interrupting the operation of the boiler

The operation is interrupted when the fuel in the boiler is let to burn up. We do not recommend to haste the interruption of the

operation in any way..

Shorttime interruption of the operation

For shorttime interruption of the operation clean from burnt fuel, empty the ash collection basin, clean surfaces of load port,

clean the ash collection space and close the load and ash port..

Longtime interruption of the operation of the boiler

For longtime interruption of the operation (e.g. end of heating season) clean the boiler properly, so as moisture causing excessive

corrosion is not kept in soot and ash..
