Congrats on getting it going.
There is/was a manometer loaner program here at one point that would allow you to borrow a manometer to measure your draft and set your baro. Or, you could head to the Grainger store up in New Castle (no sales tax) and buy one (~$40) to keep installed so you can tell if draft is changing due to ash build up or whatever.
I started a wood fire this morning for the first time this season. It's already up to 73* in here. Probably keep it going off and on through the weekend but since it is supposed to get to the mid-60's next week I'll let it die out then. Usually don't get going full bore with coal until sometime in Nov.
