The valve and regulator assembly consists of a pressure regulator and the gas control valve. The pressure regulator reduces the high-pressure gas from propane cylinder down to the proper pressure needed for the burner. The control valve allows you to turn the gas on and vary the burner flame. The regulator or valve can become restricted or plugged by debris. The internal components (such as the O-rings) can eventually fail. This can lead to insufficient gas flow or the loss of flame control.
