Hello, and welcome to my experiment. After adding secondary air to my old Timberline stove, I'm experimenting with a few things. But my question is for the people with a 3.0 or larger firebox. The baffle I added inside the stove has about 5.5" of frontal clearance, and the same to the top of the inside of the stove. I think I need to decrease that dimension, and keep the off-gassing in the box a-little longer. So to everyone with a larger EPA stove, when it cools down, could you tell me the dimensions of your smoke route- width and depth? My baffle is approx. 26" wide. The free flow area at the front of the stove is currently- 26x5.5= 143 square inches. Any thoughts?
 
Sadly I am not burning right now, and I just checked my Quad 5100 insert with a 3.1 cu ft firebox. I have 4 X 22 front clearance of the baffle and 2 X 22 above the kaowool blanket.
Above the kaowool blanket the top of the stove has about a 1 inch rim that sticks down in like a diamond shape around where the flue goes up. So that would bring the clearance from the kaowool blanket to the flue to ~1 in. The area of the diamond is maybe 12 X 12. I would need to remove the baffle to measure and this is from memory.
So it seems that you have the front correct and need to reduce the top area, maybe add some bricks up there.
 
Thanks, Hurricane. I think I'll add some material to my baffle, close it down to 4" like yours.
