Sorry Ian I did not make it very clear..Its a Myson Velaire 60/80 balanced flue, when the boiler shuts down, the burner fan does not run for long enough to clear the fumes

No its burner over run when it shuts down, it leaves a smell of burnt fuel

is it an economist 60/80?
do you mean the pump overrun thermostat?
if so the time that you refer to will be an estimate, as it is an overrun thermostat, not a timer, and will cut out according to the temperature and not a time.
and if it's not causing a problem then leave it be.
