Firing-up process
The firing process is carried out as follows:
●
Feeding time - the feeder feeds the starting portion of fuel;
●
Ignition test time - operation of the fan and feeder to start a fire from embers;
●
Firing-up time - operation of the blower together with the igniter;
The firing-up cycle has 3 attempts, if the boiler does not fire up the message "Failed firing-up" will appear.
The operation of the igniter is illustrated by the flame
shown in the photo opposite.
The boiler is considered to be fired up when the flue gas
temperature exceeds the boiler temperature by 10
degrees.
In the picture on the right, we can see that the flue gas
temperature is not higher than the boiler temperature by
10 degrees, therefore the boiler operates in the "FIRING-
UP" mode.
If the flue gas temperature is higher than the boiler
temperature by 10 degrees the boiler goes into normal
operation mode, which is illustrated by the pictures
opposite.
