Abstract: A conveyor oven for cooking food includes an oven housing defining an oven chamber in which the food is cooked. A conveyor is operable to convey the food through the oven chamber. An opening is defined in an end of the oven chamber, a portion of the conveyor extending through a first portion of the opening. A second portion of the opening below the conveyor is closed by a removable end plug. The removable end plug is configured to pivot into a closed position while an upper edge of the removable end plug is received in a pocket formed at the end of the oven chamber by the oven housing and/or at least one stationary portion of the conveyor.
