Removing the flame sensor on Rinnai E50
Tech at Rinnai tell me to remove & clean the flame sensing rod on my almost new E50C.
I can see no threads, and no flats, just the ceramic(?) end with the wire connection.
Getting the dreaded E 02 error.
After 2 months in service and 5 months after startup this is a bit scary and we hope not a harbinger of things to come.
Thanks in advance,
