Heatpro yes I figured out purging with the link you gave me now. I want to ask you a question about my gauge on boiler. All in one gauge it says temp. boiler pressure, and feet H2O. What does that feet H2O mean? And it is lined up with lines on the boiler pressure readings like they both work together?
