Just came back inside from bringing more wood in. No smoke visible from my chimney. I have a 3/8 steel baffle and SS liner (22ft). I realize I`m not getting a secondary burn. But I am curious as to what my particulate output would be per hour? My front mounted thermometer always reads between 300-450. So I never had smoldering fires, and always use well seasoned wood. We also don`t attempt to burn 24/7, but rather 16/7. Any guestimates from those of you in the business? I can also add that we only get the chimney cleaned once every summer-that`s all it has ever needed. My insert is (1985) PE D series.
