Figured this deserved it's own thread, after all my questions getting to this point. Huge thanks to everyone who helped answer all my dumb questions! I also put a link to this forum in the video description so people can learn more.
Couple things so far:
1. LOVE IT! Gets the coldest room in the house about 80 deg so far. Our furnace is barely on, which... is a bit problematic as we do need heat in the other end of the house, but I only have two zones, upstairs and downstairs. And of course, the hardwired thermostat is 8' from the fireplace insert... so... yeah. Not sure how to solve that issue yet.
2. My air damper valve plate thing... it's bent up at a 90 degree angle because the insert is recessed into the fireplace a bit. Previous owner bent it. I'm not sure if I'm getting fully closed, or fully open. When I close it, the vertical handle runs into the side of the stove. When I open it, it hits the masonry. Not really sure what to do about that yet either.
3. I've read about efficiency. Some say, get it as hot as possible right away by burning smaller, stuff, then switch to large chunks and close down the damper for most efficient burn, and try to keep an eye on temps so it stays in the optimum burn range to avoid creosote. I've also read to let things burn all the way down to coals before refilling... which makes sense from not using wood standpoint, but then the stove is cooler and I need to get it hot again. Which is correct?
