Plan on cleaning stove for first time before burning season starts. One story house. We are still confused on the baffle on top of firebox. We would like to clean without disassembling stove pipe. Obviously, with this stove, you can't just use a brush and debris falls into firebox like some older stoves. It would collect on baffle I would assume. Is baffle easily removed on these? If we do remove baffle, is there an opening into firebox?
