The ignition spark works on all gas rings but as soon as you let go of the knob the ring goes out. 4 of the 6 will light eventually but then the sparking system keeps activating unless you depress one of the knobs again. One of the rings will not light at all and oine lights but then cuts out after a couple of minutes.
