A low pressure gas burner has a mixing chamber portion mounted to a vapour gas chamber portion. The mixing chamber portion has six individual mixing chamber barrels fixed together in a closed circular fashion, although it may have more than six hollow barrels or as few as one barrel, depending on the amount of maximum heat output for which the burner is being designed. Gas entering through an inlet is distributed about the gas chamber and then exits through a gas orifice into the open end of a respective mixing chamber barrel. As the gas moves from the orifice into the barrel a venturi effect draws fresh into the barrel. The gas and air mix in the barrel and exit at the far end past a flame retainer to be burned. It has been found that this burner functions acceptably with gas pressures as low as .5 to 8 psi, be it natural gas or other types of combustible gases. Hence, because the burner is capable of such low pressure operation, a user has the ability to choose from a wider variety of gas supplies than with prior art burners, and should therefore be able to pick a lower cost gas to reduce the burner's energy or operating costs.
