Don't know but it's 30 degrees here and wet heavy snow falling but my BGE is puffing smoke
Yadda, yadda, yadda, yadda,..... My WSM will do the same thing.
Whatcha yer point, cowboy ???
Btw, if yer BGE is puffing it's sick.
My WSM gently emits a thin blue smoke as it should.
Sorry about the snow. it's 72 and balmy.
