Alright everyone been so helpful, one more question on the glass on my new stove there was this sticker( pic below) regarding damper setting. I searched both the owners manual and the tech manual. In the owners manual it explained a little and then said to refer to figure 7, ironically the manual went from figure 6 to figure 8. Next I check the tech manual it said same thing and to refer to figure 16 that manual went from figure 15 and none there after. I'm assuming that the damper was factory set. Is this what I would use a magnahelic gauge for.
