A conveyor oven (Fig. 2) system is disclosed which includes a hood means (20) which extends over the conveyor oven (Fig. 1) and supplies make-up air and exhausts heated air. The enclosure system includes front enclosure (40) and rear enclosure walls (41) which are parallel to and spaced apart from the front and rear oven walls of the oven respectively. Additionally, a first enclosure end wall (not shown) is also included which is parallel to and spaced apart from the first oven end wall. A second enclosure end wall (45) which is parallel to and spaced apart from the second oven end wall is also included. In the enclosure system of the present invention there is an entry opening (50) in at least one of the enclosure walls which is adapted to correspond to each entry opening in the oven's walls. An exit opening (52) in at least one of the enclosure walls is provided which is adapted to correspond to each exit opeing in the oven's walls. The hood means enclosure (24), front enclosure (40), rear enclosure (41), first enclosure end, and second enclosure end walls (45) of the present invention are configured such that make-up air passes over the front oven, rear oven, first oven end, and second oven end walls before being exhausted through the hood means.
