Remove the white front casing panel. inside at the bottom you will see a metal box, this needs to be pulled off, there is a grab point at each side, pull evenly and firmly towards you the cover is held by spire clips. once the cover is off you will see the oil burner you will see a clear plastic control box with an orange light glowing, press this light/button firmly & release (this is the lock out reset.) do not reset more than twice if the boiler does not fire you will need an engineer replace cover in reverse order.
