  • Safety controls for any fuel gas fired boiler

    2012-11-3 · A pressure switch in the natural gas line stops the burner if the gas pressure gets too high. If the natural gas pressure control valve fails, excessive gas can flow to the burner. If too much natural gas flows to a combustor, the burner could go out or the flame could be large enough to cause overheating.

  • How do I adjust my boiler pressure properly? –

    The pressure gauge needle indicates the actual pressure of the system. A green zone shows the correct pressure range, while a red zone shows the critical zone.: A red needle serves as a marker, while a black needle corresponds to the actual pressure.These two needles should be on top of one other.: In some boiler models, the water pressure is given by indicator lights on the control panel.
