Yes, that's what I said to myself.
Yes there is enough area coming,
And then it worked well for 1 year and a half and nothing has changed in the room in the meantime.
I tested with the garage door open, I checked that the entrance to the fireplace was clear as well as the small holes at the level of the burner plate.

This is what makes me think of the fan, which, if it does not rotate well, becomes the main obstacle. Given the configuration of the exchangers in a condensing boiler, without ventilation, this does not work! Unlike a simple wood stove, for which natural draft is enough.

This is probably a problem during ignition ...

This could be the case if the pellets are wetter than expected (less than 10% humidity). In the event of a failed ignition, it starts the "program" again. And it begins by "filling" the plate of the burner so that the pellets are near the igniter; If this happens again, the plate may overflow ...
