    Trap

    More info wioll be needed to size the trap. If you contact your Sarco or Armstrong rep they can size it. It will be about the smallest trap you can get.

    Small is Correct

    I like using Float & Thermostatic traps these days, they are good at removing air that you will have on start-up.  You could use a 3/4" or 1" F&T-125 trap.  Make sure you get the orifice for 125 psi steam.



    I have seen some large traps on the main headers for boiler, these are there in case there is carry-over of boiler water into the steam line.  I don't usually recommend them but prefer to prevent carry-over at all costs.

    Tiny boilers

    These must be real small to only need a 1.25" main.
