Yesterday I installed the glass for the afterburner viewport in my stove, it had been missing since I got the stove, (see this thread http://www.hearth.com/talk/threads/harman-tl200-afterburner-glass-missing.101751/ ) I'm not seeing a big difference in how the stove operates, and I still see a lot of smoke coming out of the chimney. I've never owned a stove with an afterburner so I don't really know what to expect. So I'm asking others who have similar stoves what to expect. And how much smoke should I see coming out of my chimney? Can something else be wrong with the afterburner? Thanks!
