Troubleshooting a Gas-Fired Hot Water Boil

The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure. If there isn't a pressure-reducing valve, manually feed the boiler by opening up the water feed valve until the boiler pressure reaches 12 psi. The natural gas or propane control valve for the burner is closed: Make sure the valve is open.
