primary/secondary radiant loop

802vt

I have 2 separate 3 loop radiant zones 50 feet from the boiler ,one goes to a slab the other to second floor,each loop is approximately 200 feet each, at the time these were installed it was off a older smith boiler ,I upgraded to a well mclain gv5 6 years ago . I am upgrading these radiant zones to new manifolds and working on the one feeding the slab, I am doing this on my own but am learning as i go ..the old manifolds had a crossover with a valve partially opened not a true primary/secondary but worked on old boiler, I did not install these .The supply and return come down from ceiling its a small utility room so trying to fit everything in there …as I stated I am by no means a "professional"..I would like to know if this setup will work ..Its all 3/4 pipe and I realize I need to straighten out the circulator…pictures posted are of new boiler, old radiant loop to second floor, my attempt at close spaced tees for supply and return and what i am working on ..The circulator all the way to the right on boiler header is the one feeding this zone…Thanks
