6. When we already have good, strong flame, add a bigger quantity of fuel than the first time
but through the upper door. Close all doors and press the command button, 4,, START''. Hold
the button until the display shows,,'' ACC. This means that the automation entered the stage of
ignition, the fan is started and there comes to the increase in temperature of flue gases.
When firing, make sure that firewood does not struck onto the upper door with great
force, in which case it is ejected out of balance and returns to the closed position. Then the
boiler operator can have the injuries.
After some time the boiler enters the normal operating mode and this is manifested in such a
way that there are no messages on the display except for the current water temperature.
7. When the temperature of flue gases exceeds about 200 degrees Celsius, the flap inside the
boiler with handle lever on the side, should be pushed towards the front or into the working
position. Reading of temperature of the flue gases is done by briefly pressing the command
button 1, then command button 3 and then the command button 2. On the display there will
appear the temperature of flue gases. This is described in the instructions for fast handling of
automation.
8.2. Adding fuel during operation of solid fuel boiler
During operation of the boiler it is possible to add the amount of coal or wood in it, but
previously the work of blower fan should be stopped by pressing the “STOP” button (see
Quick guide for automation).
When firing during the operation, the upper door should be opened cautiously only for
2-3 cm, and hold it like that for about ten seconds. Only after that open he door completely.
This prevents possible explosive penetration of flames from the firebox towards the operator.
The boiler is possible to fire up with the coal dust and sequence of operations is the same. The
difference is that first the boiler is filled with coal dust and on the top some paper is placed as
well as the firewood.
The boiler is used both for wood and coal as fuel or with their mixture, with the note, that our
recommendation is that the maximum filling level coal is somewhat lower, as shown in the
Figure 11, “Display of the maximum amount of coal for firing."
