Boiler-side piping

Figure 7 Zoning with circulators — direct-connected system piping

Notes

•Place circulators at begin- nings of zones. Placing them at the ends of zones could result in heating idle zones.

•Size manifold piping for total flow of all zone cir- culators.

•Locate flow / check valves as close as possible to water heater boiler side connec- tions — to reduce heat loss between cycles.

Wiring

•WMCR zone controller, optional priority — Fig- ure 18, page 21.
