ABSTRACT:
A gas leak and cut-off device is provided including a gas-powered hot water heater having a cylindrical configuration with a circular top face, a circular bottom face, and a cylindrical periphery formed therebetween. The bottom face has a plurality of stanchions coupled thereto and extending downwardly for engaging a recipient surface. A gas input pipe is provided having a first end connected to a gas supply and a second end connected to the periphery of the hot water heater for supplying gas thereto to heat water. A plurality of monitors are each mounted in spaced relationship on the recipient surface with the outboard ends in line with the periphery of the water heater. Each monitor is adapted for generating an activation signal only during the detection of fluid. A control valve is mounted on the horizontal portion of the gas input pipe and has an unbiased open orientation for allowing gas to be supplied to the water heater during the lack of receipt of power and a biased closed orientation for precluding gas from being supplied to the water heater only during the receipt of power. Control circuitry is connected between the monitors and control valve for supplying power to the control valve upon the receipt of at least one activation signal.
