Abstract: A method and apparatus for detecting and preventing electrically induced fires in a gas tubing systems constructed of Corrugated Stainless Steel Tubing (CSST) and Gas Appliance Connectors (GAC). The system of the present invention may include one or more energy detection schemes to detect electrical energy surges on the gas line. When such a surge is detected, the control circuitry of the present invention causes an electric two-way main gas valve to de-energize into a position wherein the flow of gas from a gas feeder pipe to the gas tubing system is blocked and residual gas pressure in the gas tubing system is automatically vented to the atmosphere.

Abstract: A method and apparatus for detecting and preventing electrically induced fires in a gas tubing systems constructed of Corrugated Stainless Steel Tubing (CSST) and Gas Appliance Connectors (GAC). The system of the present invention may include one or more energy detection schemes to detect electrical energy surges on the gas line. When such a surge is detected, the control circuitry of the present invention causes an electric main gas valve de-energize into a closed position. In addition, the system of the present invention further includes a residual gas dispersal system that automatically vents the residual downstream gas pressure remaining in the gas tubing system after the closure of the main gas valve.
