Well the chimney sweep still hasn't got back to me and I could really do with the log burner at the moment with all this cold weather and snow looming!
I am contemplating risking it and lighting the fire anyway! Probably shouldn't do that though, fossil fuel and all that! Plus the bit that goes from the burner into the chimney is loose! With warnings of carbon monoxide poisoning occurring due to badly fitted burners I don't think I should take any risks:(
