Does this mean the flapper isn’t working properly if the knob creeks and turns hard? Since day 1 of owning this stove, it has never operated as other BK owners swear by. I’m constantly moving the knob to adjust the output, mainly shutting it down to keep it from getting too hot. A while after reloading the stove, I’ll turn the knob down to keep the flu temps in range. An hour after the burn seems to settle, the cat temps will climb, the cat will glow and get over 1300 degrees (measured with a Auber probe). And the flapper will not have moved from where I initially set it. In fact it’s always where I set it. Except on a rare occasion or two when I have the flapper almost closed i notice it’s closed by itself but doesn’t open because it’s chocking the fire out. On my stove, I can visually see the flapper, and that’s how I adjust its stopping point. Not by where the dial shows. I currently have 3 wood stoves, and have had 2 more in past homes. This stove requires way more attention than any stove I’ve ever used.
