Moved into a house last year with existing Jotul Firelight F600. Works great. Finished use for the season and had a chimney sweeper come by to clean the other day, but he could not do the work because he couldnt figure out how to remove all the elements on the inside top of the stove so he could drop a line down the chimney and clean properly. Cant find any manuals, pictures, advice etc on how to do this. No stove shop in Vancouver has a clue what I'm talking about. What is proper procedure for chimney cleaning one of these stoves? Thanks much!
