Sketch a low-pressure steam system layout showing a boiler, piping, air vents, traps, steam sep-

arator condensate pump(s), etc ., for a building system where the boiler is located in a basement equipment room. There are three stories above ground, with a steam heating device on each floor. There is a chase where the steam and condensate piping should be located, with provi-

sions for a branch on each floor. The steam line must run horizontally a short distance before rising through the chase.
