Hi everybody.
I have Ecotec Bioline 20 and it already works normal at 8 years. I clean ash from all system aprox. 1 time in every month and system works very well
But this winter start problems.
Right now comes every day 1-2 times "Hot Stock Pipe Error". I don't know what to do.
In Estonia we don't have anymore Ecotec dealer eather.
Check if the gate wings are worn.
Check also if the short pipe between the input feeder pipe and the air distribution box is clogged.
You can see this pipe on the first picture at page 4.
Clean the pipe with a wire. You have to dismount the fan to do this.
