Gas supplied from the factory is supplied at atmospheric pressure or higher via the main pipe and branch pipes to the gas pressure regulator. The gas pressure regulator adjusts the gas pressure above atmospheric pressure to below atmospheric pressure, that is, negative pressure, and supplies gas at negative pressure into indoor piping. The gas suction device on the gas appliance side is activated when the appliance switch is turned on, sucks in gas from indoor piping, and supplies it to the gas burner.
