I don't know why they don't just explain the bottom 3 buttons in the owners manual? They just say the bottom 3 three buttons need no adjustment they come preset at the factory.Not the case with my stove ! After days of playing around I finally figured out the buttons were way off! They were at 5 7 9 .... Not good ! I guess the last button should all ways be at 1 . If this was just in the manual it wouldn't be an issue! Any way I figured out the factory setting for my stove should be 4 5 1 --- Am I the only one that thinks that's stupid??? I have found other members with this stove {55 shp -22} and they play with the first 2 of the three,3 7 1 ... 5 6 1 ... Thank you responders Wonder if this company says don't touch buttons they are preset?????
