Did any of them bother to measure the differential pressure across the APS?
On a standard flue the pressure is marginal when they come out of the factory...providing the fan and heat exchanger(s) are clean and the fan is running correctly then removal of the restrictor ring normally resolves an E34. It's a well known fault by now.
