gas-flame settings: Set the control knob to the lowest setting. If the flames go out, is the gas still running? If all the flames are still burning, turn the range exhaust fan on high. Are the flames still burning? You obviously have a very dangerous situation if they go out in either instance and the gas continues to flow. Check for debris at the base of the gas jets (usually a round top-piece with holes for gas to flow that sits on top of a circular metal ring). If this is not the problem, call a professional to adjust your gas regulators.
