Group II
Possible
cause 1 .
CAUSE 1 – The flap in the boiler is closed which is operated with a handle positioned on
the side. A lot of smoke appears and flue gases do not rise fast enough so the boiler is
fading out.
The procedure for
troubleshooting 1
– Open the flap, i.e. push the lever towards the
chimney.
Possible
cause 2
.
CAUSE 2 – Fan speed in the phase of ignition. The speed of fan for primary air at this
stage is determined by the parameters and Uc00 and Uc01. If the speed is drastically
changed compared to the factory default adjustment it is not good nor is it significant to
reduce or or to increase it. In case when the fan, in the phase of ignition, is weak, then
there is no increase in temperature of flue gases, but if it is too strong it can cause the
rapid consumption of pellets in the chamber, which in turn leads to a reduction in
temperature of flue gases in the ignition.
The procedure for
troubleshooting 2
– Adjust values of parameters UC00 and Uc01 the
factory default or close to the factory default values.
Possible cause 3
CAUSE 3 – Fan speed in the flame stabilization phase. The boiler inters the ignition and
the smoke appears, on the display it says Stb, which means that it is in the flame
stabilization phase, but after that the boiler goes out. The most frequent cause for this is
too weak fan in the stabilization phase which is adjusted by means of parameter UC04.
The procedure for troubleshooting 3 – Increase the fan speed by means of the parameter
UC04.
Possible
cause 4
CAUSE 4
– Too much or too little pellets in the phase of stabilization. If there is too
many or too little pellets, while on the display it says – Stb – i.e. the stabilization, this
may cause the blocking of flame and restoring the boiler into the state extingushing. The
quantity of pellets in the stabilization phase is regulated by means of parameter CL04.
The procedure for
troubleshooting 4
– Set the value of the parameter CL04 to factory
default or close to factory adjustment.
Possible
cause 5
CAUSE 5 – The boiler has entered the phase of stabilization but it is going into the
extinction phase because there is not a sufficient increase in temperature of flue gases.
Specifically there is the stagnation, i.e. a slight decrease of temperature of flue gases
which is visible when re-filling of pallets is done into the furnace.
