My husband got the insert and (insulated) liner swept. It was expensive, a little over $200, but it had been almost a year so we needed it. I told him to pay attention so we could get some rods and brushes and do it ourselves more frequently. He's pretty aware of how to get the cap off and stuff since he already cleaned that off some prior to the sweep coming, and took a pic down the uncleaned liner. He had no idea how much creosote came out of the 16' liner, since the sweep had a vac working in there the whole time as he cleaned from the top. But the sweep took apart and reassembled the whole baffle. Do those of you who clean do this too? I was kind of wondering if it was necessary and sort of hoped that I could just open the bypass damper and let it all fall in that way, but I suppose that would inevitably end up with a bunch of creosote up there on top of the baffle to some extent. I imagine taking it out's not rocket science but I just wondered if all you guys have to do that as well. Maybe it's different because our stove is an insert?
