Breezo causing backdraft on kamado.

puff, puff, puff, whoosh with smoke shooting out the vents with pressure for about 2 seconds.... no pun intended, but am I playing with fire? Just a matter of time before this blows out my ceramics?

still trying to figure out the S1+Breezo. it should be easy, but it's not.

Last night ended in failure (again), so pulling off the fan and going old school manual.

however twice when I force the fan to work in "manual mode" ( because the s1 would not control fan, so just the a/c power) im pretty sure it puffed it's way into a back draft.
