Mmmmm.

Glad they remembered to send the boiler, otherwise it might be said that that was not needed either...

I don't think I have ever seen a boiler, steam or HW, with at least a low-point tapping for a drain or blowdown. (I think you mean this as different than a skimming port or "surface blowdown".)

It is at the very least common practice if not common sense. Anyone's powers of persuasion will not coax out low point liquids and dissolved solids. Dale Carnegie did not even try.

I also have not seen many boilers so tapped with the valve installed (freight damage), so the accessory box would have that.

Sometimes though, in a steam system, the low point may be in the near-boiler piping, under the contractor's control. Places such as a seal trap or mud drum and you have the obligation to remove mud and debris. Even if the boiler had a blow-off tapping and valve, you would still need one at the low point, if not a removable plug. Give me a full port ball valve any day though.

What are you calling a blow Down

If you mean on the LWCO then no one would not be on a probe style LWCO however if you are referring to a bottom drain or skim tapping then yes.
