: The supply manifold stub where all the zone tees branch to the zones and the return manifold stub would be removed from the manifold and the manifold used for some piping or discarded. Yes, It is the normal operation of a multizone system manifold off a boiler
: +++so to clarify, you are saying to pipe that vertical 1.5" pipe that is currently attached to the tee into the top of the tank.
+++ Yes; the zones can come off the top of the 2-inch tank top conection without the rest of the manifolding.
: Would the 1.5" return manifold pipe and boiler inlet pipe be teed right at the tank?
: Yes, on a 2-inch tee.
: +++It would be a tee that is 2" with a 1.5 " connection on top for return.
That won't be a flow issue when both the boiler circ and return zones are running all through the tee?
+++ No If you had two stubs out of the tank right next to each other it would be the same situation. Because they are on the same tee doesn't make water flow to the zone return from the boiler return.
: As far as the Spirovent, etc I was just going to have the plumber get an actual Spirovent by Spirotherm.
: Do you have any recommendations on exactly what to get for this application?
No, a good vent from Spirovent, B&G, or Taco will vent.
