Basic Steam question
1. From the risers I know there is a minimum 18 inches but is there a max? So go high as I can, like 24 or 30 inches?
2. With 2 or more take off is there a minimum or maximum on how far apart from each other.?
To rephrase the question for an example after the riser then going towards the equalizer does it matter if it’s close nipples or 6 inches from each other? I’m

    As long as you have the minimum (and I would think of that as 24 inches from the water line, not 18) there really isn't a limit, but shorter becomes better at some point over that, as where the riser joins the header is where entrained water gets a chance to separate from the steam.

    If by two or more takeoffs you mean the connections to the steam mains in the house -- no, so far as I can figure out there really isn't a minimum distance between them, or from them to the equalizer -- just keep some pitch on the header.
