Buderus GB142/30 no fire on initial start-up
I just installed a new Buderus GB142/30 for a customer. This is my fourth Buderus install, so I'm new at this, but every other GB142 I'veinstalled worked fine from the start. My problem is that when I went to start it, the intake fan ran to purge the combustion chamber and then it did nothing after that. I'm not getting an error code, but the LED gives me the temp (63 deg F.), water pressure (P19) and OH indicating that the unit is ready to run. However after several attepts it won't respond to the stat calling for heat. Any thoughts?
