I have a wood-burning stove Contura C250, installed in 1995 in an apartment.
I have now discovered that the fireproof stone slab on the right side of the stove has started to break with small pieces of stone falling off, it seems to be starting on the left side as well.
Where can I turn to repair or find a new stone slab in Stockholm?
I don't dare to use the stove before it is repaired. Attached is a picture.
