Boiler fires but after 10 minutes goes out, as does the pilot light. have drained out flushed through and filled again with inhibitor. thermo coupling looks ok, but pilot light looks tall, could this be a sticky gas valve?

hi harry, i wouldnt have thought it was the gas valve. moor likley to floppy pilot light lifting off the thermo coupler . you didnt say if it was bf or cf flue type .
