15. IGNITING
The wood in the boiler burns out through the refractory nozzle. Place small pieces of wood and
chips on the nozzle so that the nozzle is permeable and the flame can pass through the nozzle. Use
a paper or a solid ignitor for ignition. In the Menu, touch "Ignition", and the fan will be activated.
The ideal fan speed for heating is in the range of 20 to 40%. Higher fan speed may cause the flame
to blow out. But these values are set from the factory in the Service menu.
It is now necessary to wait for the wood to start to burn and then close the door. The boiler will
automatically enter the "Operation" mode after reaching the chimney temperature above 45 ° C.
When this happens, boiler goes to "Operation". The boiler will now work to achieve the set CH
temperature by modulating the fan speed.
16. WORK
In operation, the boiler is controlled according to the CH temperature you set and also the flue gas temperature. If the flue gas
temperature drops below 45 °C, a refueling necessary to keep flame inside the boiler.
The fan operates until the set CH temperature is reached. Then, the fan will be deactivated. The boiler temperature may continue
to rise, depending on the chimney draft and the opening of the primary air flaps.
The correct setting of the primary and secondary air flaps is indicated by a line above the flap rod. This setting ensures the required
boiler output and ideal combustion emissions.
If you want the fuel in the boiler to withstand the flame longer, the primary air rod on the side of the boiler can be closed more.
The flaps can never be closed to 100%, as the burning fuel always requires at least a minimum air supply for proper combustion.
During combustion, there is accumulation of fumes in the filling shaft. Therefore, never open the filling door during
burning. Wait for the chimney temperature to drop below 45 °C, leaving only the hot layer that forms the smallest
amount of smoke in the filling chamber. After that, then you can put more fuel inside.
The primary air rod on the side of the boiler influences the boiler output. The figure shows the setting to
achieve the desired boiler output. By closing, you reduce the boiler output and extend the burning time. The
position of the flaps must be identical on both sides, otherwise the wood in the filling chamber will burn
unevenly.
O – open flap position
Z – close flap position (still allows the air to enter the boiler)
The secondary air rod is located in the front of the boiler. It fumes the combustion air directly into the nozzle
and improves the quality of combustion of fuel and gases. The ideal position of the flap is indicated by a line
above the flap rod. During burning, there is no need to interfere with the flap position. In general, if you close
the primary flaps, you can move the secondary flap at the same rate so that the combustion quality is as
good as possible. While still in the closed position, the flap still allows air to be drawn into the nozzle.
17. FUEL LOADING
Fuel is added to the boiler when only the hot layer of wood remains in the filling chamber, all the large pieces are burned. It
happens according to the actual flue gas temperature, which is displayed at the top right of the display. The standard combustion
temperature is above 100 °C. If the flue gas temperature drops below about 50 °C, only the hot layer remains in the boiler and the
boiler is ready to load new fuel inside.
Before opening the filling door, move the suction flap to the open position and wait for 20 seconds. Opening
the flap ensures that the residual smoke is drawn directly into the chimney. After that, the door can be
opened, see if all the smoke is sucked out and then open the door slowly.
Load new logs onto the hot layer. Use gloves because the hot layer is really hot. After loading the wood, close
the door and remember to move the suction flap to the closed position.
