Abstract

A pilot tube assembly for easy repair and/or replacement of a pilot hood is disclosed. In one example, a field configurable burner tube assembly may include a burner tube, a pilot hood, wherein the pilot hood engages the burner tube and can be secured to the burner tube in any of two or more different orientations in the field, a thermo-electric device, and a bracket for carrying the pilot hood and burner tube assembly adjacent to the thermoelectric device.

First claim

What is claimed is:

1. A field configurable burner tube assembly for a pilot burner, comprising:
a burner tube;
a pilot hood;
wherein the pilot hood is securable in any of two or more different orientations in the field via a set screw, the two or more different orientations being within 90° or less of one another;
a thermo-electric device;
a bracket for carrying the pilot hood and burner tube adjacent to the thermoelectric device, wherein the bracket has a first side and a second side with an aperture extending between the first side and the second side, the burner tube positioned on the first side of the bracket with an end portion of the burner tube extending through the aperture, a collar positioned on the second side of the bracket, and including an aperture extending through the collar with the end portion of the burner tube extending into the aperture of the collar;
the end portion of the burner tube including an aperture configured to accept and engage at least part of the pilot hood; and
wherein the set screw extends through a set screw hole in the collar, through a set screw hole in the end portion of the burner tube and rests against part of the pilot hood that is accepted by the aperture in the burner tube.

2. The field configurable burner tube assembly of claim 1 wherein the set screw frictionally engages the pilot hood to frictionally secure the pilot hood relative to the collar.

3. A field configurable burner tube assembly for a pilot burner, comprising:
a burner tube;
a pilot hood;
a set screw;
wherein the pilot hood is positioned in any of three or more different orientations relative to the burner tube via the set screw;
a thermo-electric device;
a bracket for carrying the pilot hood and the burner tube adjacent to the thermoelectric device, the bracket having a first side and a second side with an aperture extending between the first side and the second side;
the burner tube is positioned on the first side of the bracket and has an end portion that extends through the aperture in the bracket and past the second side of the bracket, the end portion of the burner tube including an aperture configured to accept at least part of the pilot hood; and
a collar is positioned on the second side of the bracket and engages at least part of the end portion of the burner tube and is secured relative to the burner tube via the set screw, the collar including an aperture extending through the collar, with the end portion of the burner tube extending into the aperture of the collar;
wherein the set screw extends through a set screw hole in the collar, through a set screw hole in the end portion of the burner tube and rests against part of the pilot hood that is accepted by the aperture in the burner tube.
