Abstract
A gas appliance retrofit drive orifice is provided for use in resizing the existing orifice in a gas burning appliance. The retrofit orifice comprises an elongated body having an enlarged diameter head formed on one axial end and a fluid passage formed axially through the body. The end of the elongated body opposite from the enlarged head forms a pilot section and is inserted into a receiving hole drilled in the existing orifice. A retention portion axially adjacent the head is substantially the same or slightly larger than the drilled receiving hole whereby upon driving the retrofit orifice into the receiving hole, the retention portion frictionally engages and secures the retrofit orifice to and fluidly coupled with the existing orifice.
