Abstract

A gas control assembly for a forced air furnace which includes a support frame having a top surface and two contiguous side walls which define an enclosure. A planar one piece burner assembly which has a plurality of burners and having two opposite side edges with one edge containing indexing means is positioning in a predetermined location within the enclosure of the support frame. A elongated gas manifold having a closed end and an open end which is configured to mate with the burner assembly to provide a source of combustible fuel to each of said burners is connected in fixed engagement to the support frame at its closed end through a hole in one side of said support frame and by a bracket at the open end which is attached to the other side of said support frame. The side walls of the support frame also contain slots which mate with edges of the burner assembly to provide for proper alignment of the burner assembly.

Claims

1. A gas control assembly for a forced air furnace which comprises in combination:

(a) a support frame having a top surface and two contiguous side walls which define an enclosure,

(b) a planar one piece burner assembly having two opposite side edges with one of said edges containing indexing means for positioning said assembly in a predetermined location within the enclosure of said support frame,

(c) an elongated gas manifold having a closed end and an open end and which is configured to mate with said burner assembly to provide a source of combustible fuel to each of said burners with said manifold being connected in fixed engagement to said support at its closed end through a hole in one side of said support frame and by a bracket at its open end which is attached to the other side of said support frame.

2. The assembly of claim 1 in which the side walls of said support frame contain slots which mate with edges of the burner assembly to provide for proper alignment of said burner assembly.

3. The assembly of claim 1 in which the indexing means comprise a notch at one corner of the burner assembly which is positioned to index with stop means contained on one inside wall of said support frame.

4. The assembly of claim 1 in which the burner assembly further includes an integral flame sensor bracket and an ignitor bracket mounting.

5. A gas control assembly for a forced air furnace which functions to effectively shield flames from stray currents and provides for accurate burner alignment which comprises in combination:

(a) a support frame having a top surface and two contiguous side walls which define an enclosure with said side walls each containing a horizontal slot,

(b) a planar one piece burner assembly having two opposite side edges with one of said edges containing indexing means for positioning said assembly in a predetermined location within the enclosure of said support frame, with said side edges being adapted to mate in the slots of the side walls of said support frame,

(c) an elongated gas manifold having a closed end and an open end which is configured to mate with said burner assembly to provide a source of combustible fuel to each of said burners with said manifold being connected in fixed engagement to said support at its closed end through a hole in one side of said support frame and by a bracket at its open end which is attached to the other side of said support frame.

6. The assembly of claim 5 in which the indexing means comprise a notch at one corner of the burner assembly which is positioned to index with stop means contained on one inside wall of said support frame.

7. A gas control assembly for a forced air furnace which comprises in combination:

(a) a support frame which includes two oppositely disposed side walls which define a space therebetween,

(b) a planar one piece burner assembly having two opposite side edges with one of said edges containing indexing means for positioning said assembly in a predetermined location in said space between said side walls of said support frame,

(c) an elongated gas manifold having a closed end and an open end and which is configured to mate with said burner assembly to provide a source of combustible fuel to each of said burners with said manifold being connected in fixed engagement to said support at its closed end through a hole in one side wall of said support frame and by a bracket at its open end which is attached to the other side wall of said support frame.

8. The assembly of claim 7 in which the side walls of said support frame contain slots which mate with edges of the burner assembly to provide for proper alignment of said burner assembly.
