Chilled water systems

Figure 10 Chilled water system plus optional

1. Install boiler so that chilled medium is piped in parallel with the heating

DHW piping

 

boiler. Use appropriate valves to prevent chilled medium from entering

 

boiler. See Figure 10 for typical installation of balancing valve and check

 

valve.

 

2. The space heating system may be zoned with circulators if a separate

 

circulator is supplied for the chilled water loop.

 

3. If boiler is connected to heating coils located in air handling units where

 

they can be exposed to refrigerated air, use flow control valves or other

 

automatic means to prevent gravity circulation during cooling cycle.

 

 

Follow these piping guidelines below to ensure chilled water

 

 

 

 

does not enter the boiler loop.

 

 

 

 

Chilled medium, if used, is piped in parallel with heating boiler

 

 

 

 

as shown in Figure 10. Use appropriate valves to prevent chilled

 

 

medium from entering boiler.

 

 

If boiler is connected to heating coils located in air handling

 

 

units where they can be exposed to refrigerated air, use flow

 

 

control valves or other automatic means to prevent gravity

 

 

circulation during cooling cycle.

 

NOTE 1: To ensure adequate flow rate through the boiler, use the following

 

pipe size on all boiler loop piping (connecting boiler to and from

 

the primary/secondary connection, item 21):

 

Ultra-80 or Ultra-105 – 1" or larger.

 

Ultra-155 or -230 – 1¼" or larger.

 

Ultra-310 – 1½" or larger.

 

 

Use at least the minimum piping size above and pipe the boiler

 

 

 

 

using only primary/secondary piping as shown. Failure to

 

 

 

 

follow these guidelines could result in system problems.
