Question on stack temp target

Options

I just got my new Buderus 215/4 up and running. The stack temp spec they provide is 331F, but it doesn't state indicated or net. (My guess is indicated.) Mine is running at 360F indicated/280F net. I want to avoid flue condensation of course.
Appreciate input on a minimum stack temp target.

    Not sure but I would say the stack temp would be net. That's the one that counts. Are you firing the boiler at the correct input?
