A.
This method is used to protect boilers from
condensate forming due to low temperature return
water. Generally noticed in large converted gravity
systems or other large water volume systems. See
Figure #6
.
B. These methods are used to protect systems using
radiant panels and material they are encased in
from high temperature supply water from boiler
and protect boiler from condensation. See
Figures
#7 and #8
following page.
C.
This method is used to protect boilers from
condensate forming as well as protecting heating
system from high water temperature. See
Figure
#8
following page.
Note:
When using bypass piping, adjust valves A and B
until desired system temperature is obtained.
7.
Bypass loop piping must be same size piping for supply
and return.
