    Not sure whether there is

    a "correct" way to do it -- but so long as the vaporstat isn't subject to getting water in it...

    Mine is piped with a regular red brass pigtail, then a snubber, then the vaporstat.  The oddity in my install is that the vaporstat is on a tapping on the drop header, not on the boiler (there are two pressurstats on the boiler directly).

    I would go for a 0 to 3 psi gauge to go with it -- but keep in mind that you need to keep the 0 to 30 gauge to keep the building inspector and insurance fellow happy.
