G. SPECIAL APPLICATIONS
1. If the
P
ure

ire
®
boiler is used in conjunction with a
chilled medium system, pipe the chiller in a separate
secondary loop.
a. Assure that the boiler circulator is disabled during
chiller operation so that chilled water does not
enter the boiler.
b. Install a flow control valve (spring check valve) to
prevent gravity flow through the boiler.
c. See Figure 4.7 for recommended system piping
for chiller operation.
2. For boilers connected to heating coils in a forced
air system where they may be exposed to chilled
air circulation, install flow control valves or other
automatic means to prevent gravity circulation of the
boiler water during cooling cycles. See Figure 4.8 for
an illustration.
