Remove the gas control knob and turn the adjustment
screw at the side of the valve shaft fully clockwise.
Once the above is complete, refit the knob and verify that the
burner flame is stable (the flame must not extinguish when
turning the control knob rapidly between maximum and
minimum position). Leave the control knob at the minimum
