Ferroli F30B digital display not working correctly?

Hi peeps,
i have a ferroli F30B boiler, which works on lpg. The digital display is not working correctly i have spoken to Ferroli they say i need to replace the PCB board. Before i try and source a pcb board i was wondering if i asked you the professionals first.
The bit that is putting me off is that Ferroli told me that the new pcb will need to be programmed to run on lpg is this true?
Any help or advice would be fantastic or somewhere i can source a pcb cheaply even better,
