Convection conveyor oven manifold and damper system

A gas manifold comprising:

• a housing defining an interior volume, the housing including
• a gas inlet in fluid communication with the interior volume,
• a plurality of gas outlets in fluid communication with the interior volume and spaced apart along the housing, each gas outlet of the plurality of gas outlets configured to be coupled with a gas burner, and
• a plurality of valve openings into the interior volume and spaced apart along the housing such that there is no fluid flow through the plurality of valve openings to the plurality of gas outlets, wherein each valve opening of the plurality of valve openings is aligned with a gas outlet of the plurality of gas outlets;
• at least one valve coupled to the housing and configured to be selectively received in any one of the plurality of valve openings, wherein the at least one valve has a first position to block a flow of gas from the gas inlet to a first gas burner coupled with a first gas outlet and a second open position to allow the flow of gas from the gas inlet to the first burner, the first gas burner in fluid communication with the interior volume, wherein the first gas burner is coupled to the first gas outlet independently from the at least one valve;
• and
• at least one cover plate configured to be coupled to the housing and selectively disposed over any one of the plurality of valve openings to close the selected valve opening.

A gas manifold comprising:

• a housing defining an interior volume, the housing including
• a gas inlet in fluid communication with the interior volume,
• a plurality of gas outlets in fluid communication with the interior volume and spaced along the housing, each gas outlet of the plurality of gas outlets configured to alternatively be coupled with a gas burner or a plug to close the gas outlet, and
• a plurality of valve openings into the interior volume and spaced along the housing, wherein each valve opening of the plurality of valve openings is aligned opposite a gas outlet of the plurality of gas outlets such that there is no fluid flow through the plurality of valve openings to the plurality of gas outlets;
• at least one valve coupled to the housing and received in a first valve opening of the plurality of valve openings, wherein the at least one valve is aligned opposite a first gas outlet of the plurality of gas outlets, wherein the at least one valve has a first position to block a flow of gas from the gas inlet to a first gas burner coupled to the first gas outlet and a second open position to allow the flow of gas from the gas inlet to the first burner, the first gas burner in fluid communication with the interior volume, and wherein the at least one valve is configured to be selectively received in any one of the plurality of valve openings;
• and
• at least one cover plate configured to be coupled to the housing and disposed over a second valve opening of the plurality of valve openings, wherein the at least one cover plate is configured to be selectively disposed over any one of the plurality of valve openings.

A gas manifold comprising:

• a housing defining an interior volume, the housing including
• a gas inlet in fluid communication with the interior volume,
• a plurality of gas outlets in the housing and in fluid communication with the interior volume, the plurality of gas outlets spaced along the housing, each gas outlet of the plurality of gas outlets configured to alternatively be coupled with a gas burner or a plug to close the gas outlet;
• and
• a valve coupled to the housing and aligned opposite a first gas outlet of the plurality of gas outlets, wherein the valve has a first position to block a flow of gas from the gas inlet to a first gas burner coupled with the first gas outlet and a second open position to allow the flow of gas from the gas inlet to the first burner, the first gas burner in fluid communication with the interior volume,
• wherein the first gas burner is coupled to the first gas outlet independently from the valve.
