yup, it happens. that's how you know your wood is properly seasoned, wet wood won't do that :)

MPD might have been closed a tad too much

Your wood is too dry and too much surface area. The wood combusted into gas and unburned particals from the heat. The fire was starved for oxygen and created mini-backdraft explosion. You simply overwhelmed the combustion air intake of the stove.

Mix some larger chunk wood in with that pallet wood and slow your fire down. Burning that hot can't be too good for the stove.

I had that with my old VC Defiant. Posted about it just the other day over in this thread. Use to fill my downstairs room with smoke in the middle of the night :shock:
