Dennis, I'm burning oak that is 1 yr seasoned and shows 19% and 2yr maple showing about the same, and there is always more soot on the left corner of the glass than any other location. Would this indicate an air leak? If so, how would you resolve it? Stove chalk the inside joint in that area? Might call woodstock and discuss this......thanks.
Take a lighter around the outside of that glass and see if the flame gets sucked in anywhere. It could be a gasket issue or maybe just draft or weather conditions.

. And we have no season's, no fall, no winter, no spring. Tree's don't change much down here. what you see is what you get. It's either warm or hellish hot most of the time. We do get our little cool spells now and then during the heart of so called winter but our summers are something strait from down below and I hope and pray I don't have to endure to many more of them.I'm a weather buff and let me tell ya it's just downright boring here as far as that goes. Like right now, there is no real change in our day to day weather for the next 7 days
. Looking long range the next burn I get will be after christmas. I wouldn't have puchased a stove right now but wanted one for so long and with the tax incentive at the time, I couldn't pass it up. After rebates and incentive, wound up only putting about 1500.00 in the stove and chimney package, and its going with me when I leave FL
!! Sorry so long, I get carried away on this subject.....
