    Vertical separation between standard sidewall sprinklers

    Well, I cleared things up quite a bit with a site visit. The submittal I was working off of made it appear that the duct run would be parallel with the wall on which the sidewall heads are going, with a stand-off, so that's why I was worried about vertical spacing/stacking and cold soldering...
