Ok, so HB is 100% correct with this statement; but many and I mean many people don't have draft within spec of what BK calls for (.05" while running at max setting, cat engaged) I myself never really gave 2 cents of my time to draft until this season when I went through my second cat on the stove (within 5 years) Having a higher draft than what is called for by spec allows more air to travel though the system, yes the t-stat can reduce flow but sometimes finding that sweet spot is nearly impossible, it will click over then the flames die out and loss of heat occurs during colder times when higher stove top temps are needed, or the draft is strong enough (my case) that the t-stat wont kick over unless ran extremely low (stall area) or the heat gets sucked out faster and up the flue creating less transfer for stove top temps to rise, allowing more air and fuel to hit the cat and make it self destruct with heating temps over 1500 deg f.
In an earlier post I asked a member to post pics of there underside of the cat - case, this metal will turn brown / red when overheated, just like steel in after a building fire.
Yeah, I had a feeling that the thermo was a tradeoff between benefits and drawbacks..kenny fleshed out those suspicions in that post.Very good post. I have no idea what my draft is. As I am positive 95% of all wood stove (including BK) are in the same boat.
95%? Maybe more like 99.something. Yet they call them "set and forget." Hmmm..
We need an "unlike" button..
