Abstract

A burner assembly including a gas inlet fixture for use with a burner tube, the gas inlet fixture including a plurality of tabs to engage a neck of a gas control valve to improve ignition and center the gas flow down the center of the burner tube.

First claim

What is claimed is:

1. A gas inlet fixture for use with a gas burner tube in conjunction with a gas control valve having a neck and a gas orifice, the burner tube having an open end, a length and a cross-sectional shape, the gas inlet fixture comprising:
a face generally perpendicular to the longitudinal axis of the open end of the burner tube, the face having a central opening and at least two tabs adjacent to the central opening and projecting generally rearward from the face;
a plurality of rearwardly projecting flanges generally perpendicular to the face, the flanges adapted to cooperate with the open end of the burner tube; and,
wherein the tabs of the central opening slidably engage the neck of the control valve to provide positive contact with and a friction fit between the tabs and the neck of the control valve such that the gas inlet fixture is free to move longitudinally along the neck of the control valve to accommodate the expansion and contraction of the burner tube along the neck of the control valve, and wherein the tabs of the central opening substantially centers the neck of the control valve with the center of the burner tube.

2. The gas inlet fixture of claim 1 wherein at least one securing member is provided to secure the gas inlet fixture to the burner tube.

3. The gas inlet fixture of claim 1 wherein inverted v-shaped members are provided and function as a venturi within the burner tube.

4. The gas inlet fixture of claim 1 wherein three tabs are provided.

5. The gas inlet fixture of claim 4 wherein the face is rectangular.

6. The gas inlet fixture of claim 5 wherein the burner tube is rectangular in cross-section.

7. A gas inlet fixture for use with a gas burner tube in conjunction with a gas control valve having a neck and a gas orifice, the burner tube having an open end, a length and a cross-sectional shape, the gas inlet fixture comprising:
a face generally perpendicular to the longitudinal axis of the open end of the burner tube, the face having a central opening and at least two tabs adjacent to the central opening and projecting generally rearward from the face;
a plurality of rearwardly projecting flanges generally perpendicular to the face, the flanges adapted to cooperate with the open end of the burner tube;
an inclined frustroconical portion around the central opening connecting the face and the rearwardly projecting flanges; and,
wherein the tabs of the central opening slidably engage the neck of the control valve to provide positive contact with and a friction fit between the tabs and the neck of the control valve to accommodate the expansion and contraction of the burner tube along the neck of the control valve.

8. The gas inlet fixture of claim 7 wherein at least one securing member is provided to secure the gas inlet fixture to the burner tube.

9. The gas inlet fixture of claim 7 wherein inverted v-shaped members are provided and function as a venturi within the burner tube.

10. The gas inlet fixture of claim 7 wherein the face is rectangular.

11. The gas inlet fixture of claim 10 wherein the burner tube is rectangular in cross-section.
