Is there a way for me to clean this chimney from inside?

[EbS-P]

Well, I wouldn't say this is the easiest method but it can be done. Not sure I'll be able to put it back together though
The metal bits on either side that hold up the baffle also have to be removed, which has to be done while holding the baffle up off of them with one hand and the baffle is not light and the opening of the stove is not huge, so it's a little bit painful. It looks like the have tab at the rear that you lift them off of and then swing them to the inside of the stove so the can slide out of the holder at the front.
The blanket has to be manipulated a bit so it doesn't get caught between the baffle and the firebricks. The baffle seems to be exactly the same width as the gap between the firebricks.

How does one remove the top? Older Jotuls had the top bolted for shipping but one could remove those bolts and the top lifted off.

Isn’t there a cooking plate on the top. Same question how does one remove it?

Yes the top can be removed and is gasketed. Two bolts on the inside center that are accessible from the flue collar. There is also that center cook plate that can be removed as well.
