C. This method is used to protect boilers from condensate forming as well as protecting
the heating system from high water temperature. See figure 8, below.
7. Note: When using bypass piping, adjust valves
A
and
B
until desired system
temperature is obtained.
8. Bypass loop piping must be the same size piping for the supply and return.
9. Typical installation using circulators is shown in figure 9, below.
