Gas-Fired Heater with Environmental Detector

A portable heater supplied by an associated fuel source, comprising:

• a housing, said housing
• defining an interior region of the heater,
• comprising a top and a bottom,
• comprising an air inlet adapted to provide communication between the interior of the housing and the environment and adapted to provide a flow path to allow air to enter the housing;
• a fuel connection fitting adapted to provide fluid communication between said associated fuel source and said heater;
• an orifice;
• a burner assembly within the housing, said burner assembly comprising
• a fuel valve adapted to control communication between the burner assembly and the associated fuel source,
• a venturi for mixing air from the air inlet and fuel from the fuel valve into a fuel-air mixture;
• and
• a combustion region adapted for the combustion of said air-fuel mixture to produce combustion products and heat, said combustion region comprising,
• a rear face in communication with said venturi, and
• a radiant surface;
• a regulator operatively engaged between said fuel connection fitting and said burner assembly, said regulator adapted to provide a flow path adapted to pass fuel therethrough;
• a controller for selectively switching among operation states of the portable heater, wherein said operation states comprise,
• a first operational state wherein the heater is adapted to produce at least 4000 BTUs per hour, and
• a second operational state wherein the heater is adapted to produce at least 9000 BTUs per hour;
• a power source,
• wherein said power source comprises, a thermopile, a thermoelectric generator, or combinations thereof,
• said power source being adapted to generate electrical power from said heat;
• and
• a detector system adapted to detect the level of a particular gas in the atmosphere,
• said detector system adapted to interrupt combustion of said air-fuel mixture if levels of the particular gas in the atmosphere are within a predetermined range,
• said detector system adapted to use electrical power generated by said power source.
