A pyrolytic self-clean gas double wall oven having over and under ovens, and an exhaust manifold on top which receives combustion products from both ovens and vents them through a single front port. The flue pipe from the bottom oven runs up along the back of the upper oven and enters the manifold above the flue pipe for the upper oven. The entrance of the upper oven to the manifold is larger than the lower oven entrance and larger than the flue pipe exit from the upper oven so as to avoid putting a back pressure on the upper oven. Both ovens are encased by an air chamber through which air is forced to cool the outside surfaces of the double wall oven.
