焼安全装置。[Claims for Utility Model Registration] A thermoelectric element converts heat from a pilot burner into an electromotive force to be used as a power source, and a gas detection element made of a gas-sensitive metal oxide semiconductor detects incomplete combustion and activates a fuel cutoff element. In a control device, the main burner is ignited and heated with a predetermined thermal time constant.
A combustion safety device comprising a heat-sensitive element configured to stop the operation of the fuel cut-off element during the thermal time constant.
