Aug 13, 2015 · Gas-Pressure Switch. Some boilers require gas pressure switches to meet code compliance. The gas pressure switches are to verify that the gas pressure is within a safe range. If the gas pressure is too low or too high, the burner will not operate correctly. Several years ago, a main gas regulator failed in Chicago. People were reporting five foot tall pilot flames on their stoves. The high gas pressure switch will be located on the burner head. The low gas pressure switch …

Jun 24, 2017 · The pressuretrol starts and shutdown the boiler according to adjusted pressure it also controls its operating range. For example, an average operating range of a steam boiler may be 240 to 250 psi. When the steam pressure in the boiler drops 10 psi, the boiler will start up automatically. When the pressure reaches to 250 psi, it will shutdown the boiler. In case of modulating pressuretrol it controls the boiler firing at high and low …
