The gist of the present invention will be explained below.In indoor piping that supplies flammable gas into the house, an automatic gas cutoff valve is installed in a part of the outdoor part of the house, and on the downstream side of the automatic gas cutoff valve, outdoors,
A gas pressure regulator is installed to adjust the secondary pressure to below atmospheric pressure, and the pressure of the gas flowing through the indoor piping is always adjusted to below atmospheric pressure. When a gas suction device is attached to burn flammable gas in a combustor, this suction device sucks in flammable gas adjusted to below atmospheric pressure from indoor piping and supplies it to the burner. This is a supply method, and since the gas pressure inside indoor piping is always below atmospheric pressure, gas will not leak indoors even if there is a crack or an accidental opening in the indoor piping or in the pipes, etc. .

6 is a secondary pressure detection device attached to the secondary side of the zero governor 3. This secondary pressure detection device 4 always detects the pressure of indoor piping, and when this detected value is below a certain standard, the automatic gas The automatic gas cutoff valve 2 is configured to open the cutoff valve 2 and close the automatic gas cutoff valve 2 when the secondary pressure exceeds a certain standard.

In the method of the present invention, by employing the above configuration, city gas supplied from the gas conduit 1 at a pressure higher than atmospheric pressure is adjusted to lower than atmospheric pressure by the zero governor 3 and then supplied to the indoor piping 5. For this reason, a. Even if a gas leak occurs in the indoor piping or a part of the terminal terminal, the gas pressure in the indoor piping 5 is below atmospheric pressure, so gas will leak from the indoor piping or terminal. Without a doubt,
There is no danger of ignition or poisoning due to gas leaks.
