I find the air and bypass levers very easy. Horizontal - closed. Vertical - open. My bypass handle rotates slightly more than vertical - about 30 degrees beyond, for a total of about 120 degrees. My handle made a really wierd noise last week. Woodstock told me to loosen the allen head screws in either end of the handle, open the top of the stove, make sure the bypass was closed, and then tighten the screws. They are designing a new method of fastening the bypass handle.... The smoke baffle is not an issue for me...I seldom load the stove that full. Get a huge amount of heat with the stove 3/4 full. Wish the door was about an inch wider. I load the back, then the front, then the middle, Inconal screen has been redesigned, so not an issue on a new stove. Have not had to adjust the handle. Fireview was easy to adjust. Have an interior double wall ICC chimney, and have excellent draft, extremely easy starts, no problem with smoke. If you have an issue with smoke, you could try opening air all the way for a minute, opening bypass, then after a minuite closing draft before opening door. Should have a good strong draft going, an is you shut the primary air after establishing a good draft, it may pull air in through the door and keep a good draft going that way. If you do this: (a) open door AS SOON AS you close draft./ (b) remember to open draft AS SOON AS you close door. WHAT I DON'T LIKE ABOUT THE STOVE: No one wants to go to bed, including house guests. Everyone wants to sit in front of the fire, then sleep downstairs in front of the fire. If anyone in your household likes to sunbathe, I guarantee they'll sleep in front of this stove. It doesn't have an oven HEAT: I have a severely handicapped brother who used to get dangerously close to the Fireview, because it was toasty warm, but my house was not always, because the FIreview wasn't big enough for my large home. With the Progress HYbrid, the home is so comfortably and uniformly heated that he ignores the stove. When people come in from a cold day, theny stand in front of the window to get warm. That usually lasts about a minutes...then they back away from the hearth and either lie down on the sheepskin rug, about three feet from the stove or sit on the chairs or sofa.....semicirclular placement about 9-12 feet from the stove. One is warm, but not boiling hot. Love the stove. Addendum: One can sit quite close to the stove as long as not directly in front of the window. We have a chair placed to the side, just past the side clearance recommendation. Very comfortable.
