A paint bake oven (10) including an outer insulated housing (12), the outer insulated housing having an inner wall surface (14). An inner housing (16) is disposed within the outer housing (12) and has an outer wall surface (18) spaced from the inner wall surface (14) to define a gas flow channel (20) therebetween. The inner housing (16) has an inner product passageway (22). A gas supply plenum (46) is disposed above the inner housings for supplying a gas flow to the gas flow channel (20). A gas exhaust passageway (38) exhausts gas from the product passageway (22). The oven (10) is characterized by including a manifold wall (28) for directing the gas flow along a flow path from the gas supply plenum (46) downwardly along the inner wall surface (20) of the outer housing (12) and then upwardly over the outer surface (18) of the inner housing (16) to uniformly distribute the gas flow over the inner housing (16).
