    My WaterFurnace Series 7 is in use about 6 years. I was cleaning the condensate pan and noticed discoloration on what I believe the be the coaxial heat exchanger - see attached photo. Does this look normal?

    Mine looks like that also. Maybe it's from brazing the HX.

    Thanks for your input. Technician was out today on unrelated call and theorized the same!

    Good that it sounds like it's not an issue with the unit.
