A ue structure is provided for venting hot air and gases from broiler compartment b and oven compartment c. This structure embodies a flue |65 in the upper rear corner of the wrapper 20. This ilue is formed by said wrapper and a wall which includes a vertical portion |66 which has its upper end flanged, as at |66a, andvwelded to the inner face of top member 23 of the wrapper and a downwardly and rearwardly inclined portion |61, the lower end of which is welded to the back member 22 of the wrapper. -The vertical portion |66 of the wall of flue |65 is provided with an opening |69 which registers with an opening |10 in the back wall of the oven liner, through which hot air and gases from the oven compartment flow. The wall portion |66 is also provided with an opening |1| which registers with an opening |12 in the back wall of the broiler liner. An insulating element |14 isy provided around openings |69, |10, between the front wall of ue |65 and the back of the oven liner, and a similar insulating element is provided around openings |1|, |12 between the broiler'liner and the front wall of ilue |65, yfor minimizing heat transfer between said liners and iiue |65.

A stack |16 for venting hot air and gases from ue |65 is mounted on and supported from the portion of the back of the wrapper which is disposed rearwardly of the baking compartment c. These gases pass into said stack through an opening |80 in the upper rear portion of the wrapper. This stack is formed with side walls |8|, a back wall |82, a front wall |63, and an inclined top wall |84. Between the lower end of the front of inclined front wall |83 and the top wall |84, an opening is formed for venting gases from the 'l stack through horizontal slots |61 in the front wall of the splashback. The lower end |85 of the stack is open to permit air in back of wrapper 20 to flow into said stack, which receives the hot air and gases from the broiler compartment liner. Air for supporting combustion at the burner I8 for the baking compartment c and broiler compartment b enters the wrapper 20 through openings 6| and 62 in the wrapper. The baking compartment c is vented through openings |69, |10 to iiue |65. The broiler compartment b is vented through opening |12 into flue |65. Gases pass from flue |65 through opening |80 into stack |16, from which they escape into slots |81 in the splashback. The upper rear corners of the broiler liner and oven liner are angularly inset and spaced from the front wall of flue |65. Stack |16 draws unheated air from the back of the wrapper through its lower open end, to cool the air and gases discharged from the stack.

The oven compartment and the broiler compartment are both disposed within the wrapper frame 20, and are laterally spaced from each other to form a space between the adjacent walls of the compartment, in which space insulating material may be placed. Obviously, insulating material may also be provided at any and all places, wherever necessary or desired.

While the preferred form of the invention has been herein shown and described. it is to be un- 1 derstood that various changes may be made in the details of construction and vin the combination and arrangement of the several parts. within the scope of the claims, without departin from the spirit o! this invention.
