Patent ID: 7210495

Claim:
A system for selectively toggling a gas line between operating and non-operating modes, said system comprising: a control valve operably connected to a gas meter, said control valve intersecting a gas flow path downstream of the gas meter and upstream an entry point of a building, said control valve being adaptable between open and closed positions based upon stimuli received from at least one gas-powered appliance located with the building; a main gas supply line mated to said control valve and including a plurality of auxiliary lines branching to selected ones of the appliances; a plurality of sensors operably coupled to the appliances and being in communication with said control valve; and means for transmitting a control signal to said control valve and eliminating a fully charged gas line when the stimuli are detected by at least one said sensors such that said control valve can selectively allow and restrict gas flow to the appliances during operating and non-operating modes respectively.
