LP gas operation.

Additional low flame check
1. Quickly open and close the cabinet door while the cooktop burner is set on LO.

If the flame is extinguished, increase the low flame setting and repeat the test
until the flame is stable.

2. Turn the knob from HI to the lowest setting quickly. If the flame goes out at the

lowest setting, increase the low flame setting and repeat the test until the flame
is stable.

Adjusting low flame setting on cooktop burners

All Cooktop burner flames should be checked at their lowest setting. Use the
following steps to check and adjust the cooktop burner settings.

NOTES

• Low setting adjustments should always be made with two or more burners

operating at the same time.

• Call for service when you need to adjust the inner flame of the cooktop center

burner settings.

1. Turn on two or more cooktop burners and set them between MED and HI.
2. Quickly turn one of the control knobs counterclockwise to the lowest setting.

The flame should stay lit. If the flame flutters or goes out, adjust the bypass
valve on the control valve for that burner.

3. Pull the control knob for that burner straight off.
4. Using a small flat-bladed screwdriver, adjust the bypass valve screw in the base

of the valve stem. Turn the bypass valve screw counter clockwise to increase
the flame size.
