D. PIPING FOR ZONED SYSTEMS
1. See Figures 3.6 and 3.7 for basic zoned system
layouts. Circulators may be installed in either supply
or return piping. Refer to PB Heat Water Installation
Survey for additional information.
2. Run each zone pipe down then up to zone to
prevent air accumulation in piping.
3. If required, provide means to isolate and drain each
zone separately.
