Use with refrigeration systems:
• Install boiler so that chilled medium is piped in
parallel with heating boiler. Use appropriate valves
to prevent chilled medium from entering boiler.
Consult I=B=R Installation and Piping Guides.
• 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.
