As long as A (primary condensate line) the opening lower then B (secondary condensate line), then those are correct.

The catch pan, which is what I called it years ago too, is the auxiliary condensate pan.

I used to use the term 'secondary condensate pan', but that was confusing as the secondary condensate opening and secondary condensate drain line were not from that pan.

Are the secondary drain lines (as shown in dans' arrow b) required by IRC/manufactures?

Yes.


Are the secondary drain lines required to be insulated in attic? I'd think so since the primary is required to be insulated.

Yes.

But not auxiliary pan drain lines.
