ABSTRACT:
This invention reveals an improved gas valve with a thermoelectric security device that has a shortened distance from the gas inlet to the front of an appliance, enabling the overall size of the appliance to be smaller than normal for this type of device.The current invention achieves this goal by reversing the gas inlet and outlet and hence the gas flow through the gas valve.
