      According to the manufacturer, it reflects back to the boiler since it does not have a firing device.

  • Q:

    Does the BTU Input:190000 refer to the minimum BTU requirements for the Boiler to work with this indirect heater. Thanks

      That number is required for the unit to meet the rest of the listed specifications, but it can operate at lower BTU inputs. Please refer to Weil-McLain's boiler and indirect water heater manuals for specifications when specific units are paired.
