Quadrafire Santa Fe howling on startup.

Upon ignition of pellets I got a puff of smoke into the room, from a leaky door seal. Replaced it and now stove makes a loud sound like a low vibration, sounds like someone blowing over top of a bottle upon ignition of pellets. Goes away after initial fire dies down a bit.
Where should I start looking? Tried cleaning, looked for obvious leaks, etc. Not sure how the combustion air is brought into the stove.

Most pellet stoves do that or a variation of that noise
It is normal when the flame starts it burns the gases in the smoke
Normal some pellets smoke more than others and take longer to ignite.
The more smoke the more noise some people have a small explosion

Resonance from air flow, just what you say it sounds like, it is. In my case, sometimes get that from the exhaust. The combustion air comes in below the exhaust in the back (mostly). If you have outside air also piped into that, rather than just using the room air, I suppose that could resonate too.

When my CB 1200 is super clean, it has some harmonic resonance as well --it might be the mothership communicating with alien intelligence lol
