I know the smoke smell problem has been solved in the newer Progress Hybrid stoves, but what was the final fix for the original older stoves? I have a stove purchased in Spring of 2012 and I get a smoke smell especially when the cat bypass is closed. There is no visible smoke, and the smoke alarm does not go off. I have already replaced the cook top gasket with little change. I love this stove and it does a wonderful job of heating my house. 8 to 10 hour burns with only a half load are the norm for me.
