A carburetion system and method for adapting a low-Btu gas source with a low-Btu gas consumer. The carburetion system comprises a low-Btu gas inlet, a gas outlet, a zero-pressure regulator, and at least one pressure-based air-gas mixer capable of maintaining a volumetric air to low-Btu gas ratio of no more than about 2: 1. The method comprises diverting a low-Btu gas to a gas outlet when the gas consumer is off. Further, during operation of the consumer, diverting low-Btu gas to a zero-pressure regulator in order to balance low-Btu gas pressure with air pressure, passing low-Btu gas to at least one pressure-based air-gas mixer capable of maintaining a volumetric air to low-Btu gas ratio of no more than about 2: 1, mixing the low-Btu gas with air in the at least one pressure-based air-gas mixer to form an air-gas mixture, aid sending the air-gas mixture to the consumer.
