Product Q&A
3 QuestionsQ: How high does the mainfold extend above the boiler connections? I have limited headroom above the boiler.

On my unit it measures 27 inches above the back of the plastic cover where the inlet and outlet pipes come through. Sent from my iPad
Q: I have a system with 3 circulating pumps one for each zone, can I use the easy-up kit? Would I have to install electric zone valves?

Verified Reply- SupplyHouse StaffThe manifold kit just covers the near boiler boiler primary/secondary piping. You can zone by pump without zone valves and still use this manifold.
Q: does the ultra need this loop or can I use the boilers circulating pump as the circulating pump for the zone?

Verified Reply- PexSupply StaffWeil-McLain Ultra boilers require a dedicated boiler circulator and primary/secondary piping, although you do not have to use an Easy-Up Manifold Kit to create this set up.
Yes. The zone circulators do not circulate through the boiler; they circulate through the top straight piece in the loop. The boiler has counter current circulation through this loop. It seems a bit odd at first, but it is more efficient. It allows for a controlled (constant) flow rate through the boiler heat exchanger that is independent of the zone circulators; in other words the boiler circ flow is the same if one, two, three or even no zones are circulating. Doing it that way maintains rated efficiency throughout any load demand. The boiler modulates the flame to keep the temp changes measured in the zone loops relatively constant. That means optimum efficiency over a wider range of loads. The two stubs on the sides of the loop are for a DHW circulator which runs independently and is controlled by the boiler control panel. The system can be programmed to determine what system (DHW or zone heat) has priority. It usually works best to assign DHW the highest priority. DHW isn't required, but most will use it in a new install. I use mine in the wintertime and have the DHW heat exchanger in series with a hybrid heat pump water heater for summer use which allows the boiler to be shut down when zone heat isn't required. I run a circ pump through the two tanks in series and it is like having a 160 gallon water heater. That works exceptionally well by the way. Hope that helps.
You either need THIS loop or as in my case didn't have enough ceiling height so my plumber had to re-create this.( Took forever) I still have this piece sitting next to my boiler if you need:-) Anyway you look at this, it costs as much to install as the boiler costs. Very complex set-up, but I love it, No noise and heat bill cut less than in half.
