1. A portable gas-fired heater comprising: a housing configured to at least partially enclose at least a first fuel source;a burner assembly disposed in the housing; anda carbon dioxide detector system comprising: a standing pilot configured to produce a pilot flame;a processor configured to: determine a level of atmospheric carbon dioxide based at least on data indicative of an identified temperature of the pilot flame; anddetermine a level of atmospheric oxygen based at least on data indicative of the level of atmospheric carbon dioxide. 2. The heater of claim 1, the burner assembly disposed in the housing comprising one or more of: a gas valve configured to receive fuel from at least the first fuel source;an orifice in fluid communication with the gas valve;an air inlet in fluid communication with the environment outside the housing;a venturi in fluid communication with the orifice, and in fluid communication with the air inlet, the venturi configured to mix air from the air inlet and fuel from the orifice into a fuel-air mixture; anda combustion region configured to provide a combustion site for the air-fuel mixture, comprising one or more of: a rear face in fluid communication with the venturi, anda radiant surface. 3. The heater of claim 2, the carbon dioxide detector system comprising one or more of: a safety valve; anda power source configured to provide power to the processor. 4. The heater of claim 3, the carbon dioxide detector system comprising a temperature sensor configured to detect a temperature of the pilot flame. 5. The heater of claim 3, the standing pilot configured to produce a pilot flame, the heat produced by the pilot flame indicative of an amount of atmospheric carbon dioxide present. 6. The heater of claim 1 the first fuel source comprising at least two propane fuel tanks, wherein the propane fuel tanks are at least partially enclosed in the housing. 7. The heater of claim 1 further comprising a fan; anda power source for the fan. 8. The heater of claim 7 the power source comprising one or more of: a dry cell battery; anda battery pack. 9. The heater of claim 1 comprising an elongated hose assembly configured to provide fluid communication between the heater and a second fuel source. 10. The heater of claim 1 comprising: a fan configured to increase air circulation through the heater; anda power source configured to power the fan, the power source comprising one or more of: a dry cell battery; anda battery pack. 11. The heater of claim 1 the first fuel source comprising at least two propane fuel tanks, the propane fuel tanks are completely enclosed within the housing. 12. The heater of claim 1, the first fuel source comprising at least two propane fuel tanks, a first propane tank comprises a first temperature controller and a first igniter and a second propane tank comprises a second temperature controller and a second igniter. 13. A portable gas-fired heating device, comprising: a housing configured to at least partially enclose at least a first fuel source;a burner assembly disposed in the housing; anda carbon dioxide detector system comprising a processor configured to: determine a level of atmospheric carbon dioxide based at least on data indicative of a detected temperature of a standing pilot; anddetermine a level of atmospheric oxygen based at least on data indicative of the level of atmospheric carbon dioxide;the carbon dioxide detector system configured to cause a fuel supply valve to be shut when a non-desired atmosphere is detected, the non-desired atmosphere comprising one or more of: an elevated level of atmospheric carbon dioxide; anda reduced level of atmospheric oxygen. 14. The device of claim 13, the carbon dioxide detector system comprising a standing pilot configured to produce a pilot flame, the pilot flame configured to heat an associated temperature sensor. 15. The device of claim 14, the heat produced by the pilot flame indicative of an amount of atmospheric carbon dioxide present. 16. The device of claim 13, the carbon dioxide detector system comprising a power source configured to provide electrical power to the processor. 17. The device of claim 13, the carbon dioxide detector system comprising a safety valve configured to close a fuel supply to the device upon cessation of receipt of an open valve signal, the open valve signal indicative of an atmosphere that does not comprise an elevated level of carbon dioxide or a reduced level of oxygen. 18. A method of manufacturing a portable gas-fired heating apparatus, comprising: producing housing that is configured to at least partially enclose at least a first fuel source;disposing a burner assembly in the housing; anddisposing a carbon dioxide detector system in operational engagement with at least the first fuel source, the carbon dioxide detector comprising: a standing pilot configured to produce a pilot flame, the pilot flame configured to heat an associated temperature sensor, the heat produced by the pilot flame indicative of an amount of atmospheric carbon dioxide present;a processor configured to: determine a level of atmospheric carbon dioxide based at least on data indicative of the temperature of the temperature sensor; anddetermine a level of atmospheric oxygen based at least on data indicative of the level of atmospheric carbon dioxide;a power source configured to provide electrical power to the processor; anda safety valve configured to close a fuel supply to the device upon cessation of receipt of an open valve signal, the open valve signal indicative of an atmosphere that does not comprise an elevated level of carbon dioxide or a reduced level of oxygen.
