A gas conveyor oven has a conveyor belt for conveying an item through a heating chamber in which separate parts or sides of the item are to be concurrently heated at different temperatures. A blower draws heated air from a gas burner into a ventilation chamber in which a first baffle directs a first fraction of the heated air from the blower into a first portion of the heating chamber; and a second baffle directs a second fraction of the heated air from the blower into a second portion of the heating chamber. The second fraction of the heated air has a different rate of flow than the first portion, because the first and second baffles are positioned asymmetrically with respect to the heater, so that the fraction of air deflected by each baffle onto a different part or side of the item differs in volume and flow rate.
