Hi,
I have been using the above stove for a while now, but wonder if any one can help?

There is a facility to change the balance between the combustion air and the quantity of pellets that are sent to the burn pot, the range is -9 to +9.
The stove is sooting up somewhat so I have steadily reduced the quantity of pellets and it has helped, but I am now on the -9 setting when using EN Plus A + grade pellets.

I initially thought that it was the length of the flue at around 7 metres that was causing the problem but having relocated the stove, the flue is now about 3 metres long, with no bends and it has not helped.

It would seem that increasing the airflow might cure this. In order to do this I suspect that I need access to the "technician menu", which requires an access code to be input, I have been unable to get that code from my supplier or the manufacturer and wondered if anyone on here knows what it is and would be prepared to reveal it? :)
Thank you for any advice that you could give
