1. If system water temperature requirements are less
than 140 °F, such as radiant panels or converted
gravity systems, use piping as shown in Figure 10
or 11.
2. If system piping is plastic without an oxygen barrier,
a heat exchanger must be used.
3. Follow instructions on page 14 and 15 to install
near-boiler piping.
