5.Turn the control knob quickly to the “LO” position after the burner lights. If the flame goes out, turn the control knob to the “OFF” position.

6.Check each cooktop burner for proper low flame. The low flame should be a minimum, steady blue flame. The flame size should be ¼" to ³⁄₈" (0.64 cm to 0.95 cm) high.

If the low flame needs adjusting:

1.With the burner flame on, turn control knob to the “LO” position and remove control knob.

2.Insert a small flat-blade screwdriver into the valve stem. Turn the valve adjusting screw to obtain the smallest flame that will not go out when the control of a cold burner is quickly turned from “HI” to “LO.” Turn right to decrease flame height. Turn left to increase flame height. Repeat for other cooktop burners as needed.

OVEN TEMP

■The oven pilot should now be larger with the flame burning against a small metal bulb.

■The oven burner should light in 20-40 seconds; this delay is normal. The oven valve requires a certain time before it will open and allow gas to flow.

To avoid damaging the hot surface igniter, do not insert any object into the openings of the shield that surrounds the igniter. Do not clean that area.

3.Check the oven burner for proper flame. The flame should be ½" (0.13 cm) long, with inner cone of bluish-green. The outer mantle should be dark blue and should be clean and soft in character. No yellow tips (not enough air), blowing or lifting (too much air) of flame should occur.

If the flame needs adjusting:

1.Turn the oven off. Wait for the oven burner to cool down.

2.Open oven door and remove oven racks, oven tray, and flame spreader and set aside.
