Note: Flow rates and pressure drops shown above are through the boiler only and include no field piping. The field piping must also be
considered when sizing system pumps.
Note: The standard factory supplied internal rear header mounted pump is sized for the boiler and up to additional 50 equivalent feet
of field piping.
