Manifold for Navien to zone panel assembled and ready to be pressed. Any thoughts before doing so?

Updated picture of manifold all pressed. I have the supply line sloping down to the zone panel, and the return line sloping up at an angle. What's everyone think?

    How are you supporting the tank?

    can’t tell if you have a shutoff between in and the air removal device.  If not I’d add one.

    @PC7060 it's supported in the back by a metal hangar strap connected to the zone panel frame. The air removal device is the brass cylinder looking object left of the top pressure gage on the panel. There is a shutoff valve left of that and the two yellow lever shutoffs closer to the top with fill and purge valves. I am also able to disconnect the manifold with it's 4 disconnects (2 on the boiler, 2 on the zone panel).

    @hot_rod yes for this particular WATTS model, vertical installation with flow up is okay.

    Anyone have concerns with the taco zone box being mounted below water?
