Well, i finally found the time to cut a section of stovepipe to the right size and move my Bukhari (see earlier blog post) to connnect with the internal chimney.
I'm pleased to say it works perfectly - and it's now in a much better position in the room, and i can close my curtains properly!
Here's a picture of it in its new place:

A typical Afghan wood stove
Hopefully this is the end of the bukhari saga. We'll see...
