To Adjust By-Pass Flame (Minimum Burner Flame):

When oven reaches the temperature at which the dial is set, the oven control cuts down the flow of gas to the amount required to keep the oven at that temperature. The control must by-pass enough gas to keep the entire burner lit to maintain this minimum flame. The by-pass must be carefully and accurately set as follows (Fig. 5).

1.Light oven burner, then turn dial to highest set tem- perature.

2.After 5 minutes, turn dial clockwise to a point slightly beyond first mark on dial (shown by "X").

3.Remove dial and sleeve.

4.With a screwdriver, turn by-pass adjustor counter- clockwise to increase flame, clockwise to decrease flame, until ther is a flame about 1⁄8" high over entire burner.

5.Replace sleeve and dial, turning dial clockwise until it locks in the OFF position.
