RE: Non-condensing Boiler Pumping with 3-way Valve HVACMech (Mechanical) 26 Feb 16 12:50 So they are using it as a outside air reset for the supply water temperature.
Aug 19, 2014 · Boiler water is up to the correct level, closing the low-water cutoff switch. The low-water light (panel) is off. The operating limit pressure control (steam boiler) or the operating limit temperature control (hot water boiler) and high limit pressure or temperature control are below their cutoff setting.
chillers and boilers need to see constant flows no matter what position the 3-way is moving to as the AHU reaches setpoint the valves moves to shut coil entering and by pass that water into the returns thru the by pass.seeing 2-wy valves on chilled water sytems is a flag where engineers go with the idea water will pass thru the coils to make the loop into that return..the chiller picks up low flow returns and reacts unloading or tripping flow switch or going off on freeze protection
The ejector overcomes the pressure drop by feeding pressurized high temperature condensate into the centrifugal pump, making it possible to pump condensate without the fear of cavitation even with an NPSHA as low as 1 m [3 ft].
The steam boiler gauge going to zero doesn't mean there's no water in the steam boiler. It just means the temp has dropped below the boiling point. I would start by draining both boilers and measuring how much water comes out. See the manual for instructions. Be sure to let the machine cool off completely before draining the boilers.
