Abstract
The present invention is a system that utilizes high pressure gas (greater than ½ psig) to control flow rate and gas discharge velocity to enable interchangeability between a plurality of gases without having to change the gas/air mixing venturi size or air opening. A new approach is to use the available incoming higher gas pressure to the appliance then control the volumetric flow rate with the first orifice and then use a second orifice to change the velocity of discharge into the gas/air mixing venturi of the burner and therefore have adjustability of gas air mixing conditions without having to change the burner system or air flow control even when changing between very different fuel gases.
