This question comes up several times and there have been differing opinions on it. Tony suggested I post how we do it and we sort of have Woodstock's blessing on this. Here is what I received from Woodstock:
"Those instructions for the first fires are great. I wish more people would follow them. It's more to cure the cast iron. If you had the time, you can usually achieve that in 2 days."
The only way I differ is that I think the break-in can be done in one day. So here is a suggestion:
1. First fire. Up to 6 pieces of kindling (1" x 1" maximum). Light the fire (super cedar works great), leave the draft full open and just let it burn out.
2. Second fire. (Stove should cool some but should not have to be cold before second fire.) Same amount of kindling. No more than 2 small or medium splits. Light the fire and let it burn. After splits get burning good, close draft to about 50%. Let the fire go until it is out.
3. Third fire. Stove should cool down some but no need to wait for total cold stove. Just luke warm. Same amount of kindling. This time 3-4 splits and light the fire. Stove top should reach 350-400. If the temperature goes higher, no worries. Again turn the draft down to 50% as on your second fire but after you feel the fire is good and established, turn the draft down to at least 25%. Let the fire burn itself out.
At this point you should be good to go with hotter fires. I'd suggest aiming for 500-550 on the next fire and finally to 600 or more. The stove should be ready for big time burning now.
EDIT: On the second burn you may or may not get hot enough to engage the cat but you should on the third burn. (200 degree stove top and 400 flue (measured on single wall flue pipe.))
I hope this will clear up the break-in for those who buy a new stove.
