    Hello: Can you give us a little more detail on what isn't working? You should be able to get a threaded fitting installed so you can hook up a test gauge like is pictured. Does that help?

    Yours, Larry

    Does the manifold have air vents on it? if they have float type air vents you need to seal the cap to get an air test to hold.

    If by chance it is a Caleffi brand, you need to use the black plastic caps to air test. the brass caps are hygroscopic and only seal when they get wet.

    The gauge Larry shows will work on any system that you can adapt it to.
