An air nozzle assembly for use in associated combustion apparatus which includes a first elongated housing having first and second axial extremities. The first axial extremity thereof is open to the interior of the first housing and tapers axially from a larger to a smaller cross section that constitutes a generally flat nozzle at the first axial extremity. A second elongated housing has first and second axial extremities. The fist axial extremity is open to the interior of the second housing, at least the first axial extremity and an axial portion of the second elongated housing are dimensioned and configured to extend with at least the first axial portion disposed within the first elongated housing. The first axial portion tapers axially from a larger to a smaller cross section at the first axial extremity. The apparatus also includes means for selectively preventing flow in the second elongated housing.
