Update:
Swapped both burner capacitors AND circuit board, just to be sure.
Did the new weighing - 1435g. Put everything together and turned it on...so far so good! Been running now 6h normally (at least I think it is normal
![:D :D](./images/smilies/icon_biggrin.gif)
)
Cleaned all the chimney pipes and boiler, just to be sure again.
Now just need to know what kind a blower percentage should I need (low, mid, high values I mean). Right now lower slightly previous values, flame seemed to be fine.
And those P.I things, have no idea what do with that.
