Connect Water Piping CONTINUED

Piping for systems requiring temperatures below 140°F:

In most systems, this type of piping is not required. If system water temperature requirements are less than 140°F, such as radiant panels or converted gravity systems, use piping as shown in FIGURE 12 or 13. If system piping is plastic without an oxygen barrier, a heat exchanger must be used.
