This is our first winter with our new Green Mountain 60. I just found this forum and somehow already have an account although I forgot about this place when we decided to buy a stove this past winter, oh well. It was an easy sell because it looked nice and had good specs but I didn't spend forever researching like I usually do.
In the manual it explains the position settings are:
low is when the air control lever is pushed all the way in.
Medium low is just under 1/4" out.
Medium high is just under 1/2"
High is when it's pulled all the way out.

The thing is.... The lever comes out a full 1.25".

So does this mean it goes all the way from Low to Medium-High in less than 0.5". And then from medium-high to high in 0.75"!?

Yes, that was just mentioned in another thread. Air control is not linear. As the draft gets stronger with a hotter stove, the velocity of air going through the air control increases.

oh! Ha. Thanks. I'll keep poking around to find it.

I found this thread which you may have been referring to. https://www.hearth.com/talk/threads...d-before-closing-primary.195556/#post-2627957
interesting.

Also interesting is how much thought and energy you all have put into this! My stove has been working wonderfully. And incedentally I have been measuring STT for fun as i've been learning this. (Although it took me 10 min to figure out what you all meant by STT).
I don't have a flue thermometer, it's double walled all the way up. I just put a blower on my stove and noticed it decreases STT dramatically depending on what speed my fan is on.

Unlike the person who posted that thread I linked, I have not been paying attention to secondary burning, char of any new wood I add, or the temp of when to add it. I just add when I need more heat. I notice the secondary and open the air control when it looks like the fire is going too low. I'm not sure what else I ought to be paying attention to if it's that important.

I've also made a habit of prematurely engaging the catalyst which may be a no no. It's just my fire burns out every night with the bypass closed, so I figured whats the harm if I start a really good fire and closing it early-- it certainly heats the catalyst up faster.

Maybe I should mention I only have Pine because I live in a pine forest. I do try to get my catalyst temp past the mid point to help burn the creosote.
