This will be the third month burning the BKUltra two months March ,April 2011,small fires only,and about a month now small stick fires. Well I fired her up last night at 5pm with about 6 or 7 ash splits none bigger than 3 inches got the fire roaring,engaged the cat I think and she burned till 11am this morning before the cat probe went in the inactive zone.The stovetop was around 450-500 and the cat probe was at 2 O'clock is this considered a good burn? I am new to a cat stove and trying to figure things out,my house went with a window open to 75,and cooled to 72 in the morning hours. My stove setting was 1.5. Any BK owners if you can shed some light on this I'd appreciate it,this website is awesome as are the people who post here every visit is a learning experience.
