    The model MST396SL was discontinued because the part number was changed by the manufacturer. No modifications were made to the replacement product MST396SL-HB.

    Q: There's a reference to hookup for an indirect (several references) including Figure 6: "Piping Arrangement for Drain Valve and Indirect Water Heating Return." Why are you saying "no indirect" on this model?

    The installation manual shows the installs for all the MST series boilers. This particular SKU number is for the model that does not include the tankless coil. There is a version offered with the coil, but this particular part number is the version that does not come with the tankless coil for an indirect water heater.
