NOTICE

Indirect water heaters are capable of transferring a limited number of Btu’s into the water. Ensure boiler output does not not exceed indirect water heater transfer capabilities.

Please note that these illustrations are meant to show system piping concept only, the installer is responsible for all equipment and detailing required by local codes.

System flow should always remain higher than the required flow for the boiler(s) when the boiler(s) is in operation to prevent short cycling and high limit issues.
