Minister of Fire
I get this every few weeks in the colder part of the winter. Usually when the thermostat decides that the stove should be warmer and the fuel load moves from sleepy coals to an active flame. Some people might call it an explosion or a burst of flames or a puff but I do get it and it certainly it must make a puff out the chimney but no smoke in the house. Looks really cool. Totally silent. Even the wife notices the cool looking burst of fire.
Huh, I guess I see a similar thing sometimes, but not accompanied by a noise or a jolt or smoke leakage or anything. I think maybe I phrased the original question badly, as this is not the effect that was causing the other guy to report explosions and smoke leaks. (Also, I think I stopped caring and won't re-ask it. )
Mine usually start as a little tongue of flame and whoosh around in a swirly pattern. Big ones stabilize as a bar of flames across the top near the cat sometimes, and sometimes it just swirls around like a caged dragon in there. It's not a firebox-filling flame as the cat was already reburning wood gas without visible flames, but it's pretty when it happens.
I've had bangs that made the pipe rattle and the door pop the rest of the way open with old pre-EPA stoves, but probably everyone who ever tried to run a sufficiently airtight stove as low as possible knows all about that already.
