Abstract
A new Combination Carbon Monoxide Sensor and Furnace Shut-Off System for automatically terminating natural gas flow to a malfunctioning boiler or furnace which is producing dangerous levels of carbon monoxide. The inventive device includes a carbon monoxide sensor system for detecting carbon monoxide, and a control valve electrically connected to the carbon monoxide sensor system and connected within a gas pipe for controlling the flow of natural gas within the gas pipe. When the carbon monoxide sensor system detects a dangerous level of carbon monoxide surrounding the boiler or furnace, a solenoid is electrically activated for closing the control valve for stopping the flow of natural gas into the malfunctioning boiler or furnace.
Claims6
A combination carbon monoxide sensor and combustion heating device shut-off system kit for control of carbon monoxide danger, said kit comprising:
- a control valve connected in a gas pipe supplying gas to a combustion heating device employing a flame to burn gas, wherein said control valve controls a flow of gas to said combustion heating device;

- and
- a pair of sensitivity switches secured within said housing for allowing manual adjustment of a sensitivity of said carbon monoxide sensor system whereby said sensitivity is shown upon said display.
In combination,
- a combustion heating device employing a flame to burn gas supplied to said heating device by a pipe:
- a thermostat adapted to control operation of said combustion heating device to regulate the air temperature of a space;
- and
- a carbon monoxide sensor and combustion heating device shut-off system for control of carbon monoxide danger from said combustion heating device;
- said shut-off system comprising a carbon monoxide detecting means for detecting carbon monoxide levels in an air space, said carbon monoxide detecting means being positioned near said combustion heating device, said detecting means comprising a carbon monoxide sensor system positioned in a housing, said carbon monoxide sensor system including a sensor device for detecting various levels of carbon monoxide in the air near the combustion heating device and an audible alarm device for emitting an audible alarm in an event a pre-determined level of carbon monoxide is detected, a power switch positioned in said housing and electrically connected to said carbon monoxide sensor system for controlling power to said carbon monoxide sensor system and a pair of sensitivity switches secured within said housing for allowing manual adjustment of a sensitivity of said carbon monoxide sensor system,
- wherein said carbon monoxide detecting means is electrically connected to said thermostat of said combustion heating device, said sensor device being electrically connected to said thermostat in a manner such that an electrical signal from said sensor device causes said thermostat to stop the burning of gas by said combustion heating device upon detection of a predetermined carbon monoxide level to thereby stop generation of carbon monoxide by said combustion heating device.
