What is the minimum size for a gas supply piping outlet for a recessed oven?

The minimum size for a gas supply piping outlet for a recessed oven is 1/2 inch. This dimension is established to ensure that the gas flow is sufficient to provide the necessary BTUs for proper oven operation. If the outlet were smaller, there could be a risk of inadequate gas supply, potentially leading to poor performance or safety hazards.

Using a 1/2 inch outlet allows for efficient gas transport, accommodating the oven's requirements without causing undue pressure drop. This is particularly important for recessed ovens, which may require more precise gas flow to achieve the desired temperature and cooking performance.

Choosing larger or smaller pipe sizes would not meet the performance requirements set forth in building codes and standards for gas installations. A size greater than 1/2 inch may not be necessary, while sizes smaller than this could lead to operational issues.
