Well, here was my fun for the day.
I only burned less than a third of a cord last year since that was all I had, but I wanted to sweep the chimney anyway partly because it seems like good practice but mostly because I wasn't sure how successful I would be at getting the sweepings out of the stove. The F45 doesn't have a bypass, so if you keep the liner or stovepipe connected while sweeping it all ends up on top of the insulating blanket that sits on top of the baffle. This is what I did for a first attempt and I won't be doing it again.
No matter what, I have to disconnect the liner which is a pain in itself because it has to be lifted a good two inches and it doesn't like to bend to allow that to happen. I think the only reason it's possible is because the chimney tiles are so large - 13x17 with only a 6 inch liner inside - gives it some space to move. My mineral wool insulation seemed to be dense enough to keep it from moving, so I had to remove it to get the liner out which is unfortunate because it makes a big mess. After getting the liner out, I discovered that I hadn't gotten the brush all the way to the bottom of the liner.
Next, I disconnected the flue collar in order to vacuum out the sweepings. If at all possible, avoid doing this. The top of the flue collar is just slightly lower than the top of my fireplace opening, so it required significant contorting to get my arm down in there to hold the nut that is not welded to the inside of the stove. After finally removing both nuts/bolts, as you can see in the photo the gasket did not survive the disassembly process. I called the fireplace store that I bought the stove from to see if they had a gasket in stock, and ended up having to make a trip there. They seemed surprised that it didn't use a rope gasket, and gave me some adhesive rope gasket free of charge. I was a little unsure about this non-OEM substitution, but after cleaning both surfaces thoroughly, carefully installing the gasket, bolting everything up, and inspecting carefully, it looks like it should seal OK. If anyone knows of a reason why this isn't acceptable, please let me know.
Anyway, after getting the flue collar reinstalled I wanted to sweep the liner again. This time I put a trash bag in a small bucket and stuck it over the end of the liner, sitting on the stove more or less where the liner is sitting in the photo. Get the brush back of of the basement, get the ladder back out, nothing like doing the same job twice! This time I actually came inside to check if I had reached the bottom - the first time I hadn't. I think the curve in the liner just before it enters the stove causes extra resistance causing the brush to stop about a foot before the end of the liner. Anyway, after verifying that the brush made it to the end of the liner I marked the brush with tape so next time I know how far down it should go. I'm happy with what came out of the liner - mostly soot and not too much shiny creosote. I know I made some beginner mistakes last season so I expected some shiny stuff.
The takeaway here is that sweeping the chimney would be a much easier job if I had gotten an insert instead of a freestanding stove, but I don't regret my decision. It's definitely a pain to do, but it only has to be done once a year.
