The full SBL explanation for citing ANF and NPNF can be found at: https://sblhs2.com/2017/07/13/citing-text-collections-6-anf-and-npnf/.
Footnotes should include the author, "work," and where the citation can be found in the classic text (chapter, section, and paragraph numbers may be given, as available, separated by periods) as well as the NPNF series/volume and page numbers.

This footnote shows a citation of Book I, chapter 3, paragraph 2 of Eusebius's The Life of the Blessed Emperor Constantine, which is found on in the First Series volume 1 on page 482.Note that both The Life of the Blessed Emperor Constantine and NPNF are italicized.
Your bibliography should list the standard bibliographic entry for NPNF (see that SBL link above), with our library copy's reproduction information (highlighted in yellow below) at the end.
A Select Library of Nicene and Post-Nicene Fathers of the Christian Church. Edited by Philip Schaff and Henry Wace. 28 vols. in 2 series. 1886–1889. Repr., Grand Rapids, Mich. : Eerdmans, 1989.
If you use a different copy (online or at a different library), you should change the reproduction information (yellow above) for the same information from the back of the title page of the copy that you used.
NPNF only needs to be listed once in the bibliography regardless of how many authors or volumes were consulted.
