Testing the Flame Stability

Test 1: Turn the knob from HI to LOW quickly. If
the low flame goes out, increase the flame size
and test again.

Test 2: With the burner on LOW setting, open and
close the oven door quickly. If the flame is
extinguished by the air currents created by the
door movement, increase the flame height and
test again.
