    A little high

    That is high for a 3 pass boiler.  Do you have the baffles in?  Is your stack thermometer ok?  Normal stack temp for the 215/4 is around 400 after adequate run for a combustion test.

    Baffe in place

    I have the two baffles that came with it in place and the thermometer I am using to the best of my knowlege is accurate.
    I since have replaced the 1.1 tip with a 1.0 using the same 8/2 air settings and lowered the stack temp only slightly to 520.
