My poterton netaheat boiler 10/16 is making a buzzing noise when on?

When the flame has been on full for approx half an hour the buzzing starts. Is this an alarm? What should I do?

i think you may find its the solenoid on the gas valve, nothing to worry about, just anoying, mind you it might pack up eventually
