I do have aMPD. I have used a couple of stoves and some you can almost choke out the fire by using MPD. However, the WM does not react as it should. It keeps roaring.
I have tried to seal all areas that I expect suck air and even made mental notes off the areas to seal, but the fire continues to rage at times. I just installed anew stainless chimney from the stove through the roof, a new MPD too before the firing season
