This is my second fire in the PH. After establishing a decent bed of coals burning pecan, during which it was difficult to achieve catalytic combustion temps, I threw 3 medium sized splits of oak in the stove. After 10 minutes in bypass and full open draft, I completely closed the draft and the bypass and the stove quickly went black. Now, about 1 hr. 50 minutes later, the box is still black but sporadically bursts into a box full of secondary flames about every 15 to 30 seconds., with the flames lasting 1 second or less. Top temp is up to 520 and either steady or very slowly increasing. The firebox seems to be accumulating gas and oxygen until a combustible mixture is achieved, then the mix is suddenly combusting with a "whoosh" and a sucking noise. Very similar to an old hit-and-miss gas engine. Not concerned, but very impressed as this seems to be an ultra-efficient mode with good quality wood.
