Sorry in advance for the simple question as I'm just a DIY.
I have a Navien condensing boiler that was installed with a whole home renov. a few years ago. The GC/Plumber who put in the unit...lets just say didn't do a great job with supports of the plumbing under the Navien. So the entire heating water and DHW manifold is hanging from the unit inlets as support with a single strap of copper being the only external support. Its not very solid at all, I'm thinking putting a lot of stress on the unit and if you happen to bump into it, the whole assembly sways back and forth. Id like to rectify that.
What I would like to do, what I think would work best, is install a few copper coated split clamps with threaded rod and plates to the manifold pipes and plywood backer board where space is available. This picture is a good example. Please note this is NOT my install:

My question is, when building and installing these assemblies around the pipes (1"), how tight do I make the whole clamp/rod/plate assembly? Do I need to account for potential thermal expansion at all?
