I’m currently building a mastersuite addition that features a newly installed miniature furnace/AC in the existing attic to heat/cool the new space. Part of the installation requires a condensation line drain. My question is: Can I tie that line into the plumbing vent system (wet vent). Or do I just run it out the house under an eave? If I were to tie it into the vent system, would I just add a wye and miniature p-trap and branch off the main stack? Any ideas?
Much appreciaton to all ideas!

Don't forget an overflow pan and drain line.

Be careful under the eaves. I was out walking the neighborhood yesterday, read wakling off TG Turkey, and saw a house with a broad rust stain spreading down the side of the house from a condensate drain. Don't know why it was rusty as condensate should be rust free ; but I was really ugly.

OK, but was the stain on the house ugly too?
Will you have gutters? Put the drain into the gutter.
Most codes that I work with will not allow a solid connection to the santary/vent system, it must be connected to a storm water line or run to grade outside the building. Make sure that you read the manufactors instructions, some require a trap regardless of where you run the line. Two things pertain to this post, manufactor and local code. Lots of luck.

Don't know where you're located, but a drain to the outside can freeze, backing condensate up into the furnace and shutting it down. I had to pull mine inside, install a pump, and run it into a trap attached to a sink drain line.
