jtown,
Thanks for the speedy reply. I understand the beginning of your reply (re: general, sediment-removing blowdown). But I'm afraid that the bit about the gauge glass went over my head. Specifically:

SRULI: Couldn't find anything in the owner's manual called anything like a "blowdown petcock". I found the "drain cocks" where the general, full-boiler-get-rid-of-sediment blowdown gets done. (And I discovered that I have a probe LWC, which obviously won't have any valves). But I can't find any drain-like things near the gauge glass that would facilitate a specific drain of the gauge glass.

SRULI: As far as the "top try cock" is this the same as the "Pressure release valve"?
I apologize for asking such remedial questions in a professional forum. As such, a suggestion for a good book on steam heating (targeted at a relatively dense home owner like myself, of course!) would be gladly accepted in lieu of a specific reply!
Thanks again,
