ABSTRACT:
A heat duct support assembly for an impingement oven having a plurality of horizontally oriented heat ducts therein, which are connected to a plenum to direct hot air from the plenum against food being conveyed through the oven. The assembly comprises two studs projecting from each of the oven opposite sides and an elongated bracket horizontally positioned between the oven opposite sides for supporting the remote ends of the heat ducts. The bracket is supported by a pair of bracket supports connected to its ends and which are adjacent to the opposite sides of the oven. The bracket supports have slots in their bottom and top edges that engage the studs in order to support the bracket between the oven opposite sides. The opposite ends of the heat ducts are supported by flanges peripherally disposed about openings in the plenum and over which the heat ducts are fitted.
The method comprises providing the studs and bracket with the bracket supports, positioning the bracket in the oven and guiding the slots in the bracket supports in alignment with the studs, and then rotating the bracket to engage the slots with the studs. Thereafter, the heat ducts are fitted over the flanges and the remote ends rested on the bracket.
