Hi again,
It wasnt the engineer that fitted the pcb that mentioned the ventilation, it was the engineer from Worcester Bosch that condemned the boiler due to ventilation issues. The pcb engineer did test the boiler after fitting it......unfortunately it had started working again prior to his visit today. He did leave the old board
