National Requirements For Gas Stoves

1. Air tightness: From the gas inlet to the gas valve, the leakage is ≤0.07L/h under the pressure of 4.2kPa.

2. Thermal efficiency: desktop stove: ≥55%, embedded stove: ≥50%

3. Carbon monoxide (CO) content: ≤0.05% (theoretical air coefficient = 1)

4. Air inlet mode: there are upper air inlet, lower air inlet, full air inlet, etc.

5. Flameout protection: The new national standard (GB16410-2007) stipulates that all stoves must be equipped with flameout protection devices.
