Having an off-center drilled orifice can lead to yellow flames due to an improper mixture of gas and air. When the orifice is not drilled correctly or is misaligned, it can disrupt the intended flow of gas. This can create a situation where there is not enough air mixed with the gas, leading to incomplete combustion. As a result, you may observe yellow flames, which indicate that carbon is being produced due to this incomplete combustion. Yellow flames also suggest a cooler flame temperature and can create more soot and carbon monoxide production.

This outcome is significant because the ideal combustion process requires a specific air-to-gas ratio, which is compromised by an incorrectly positioned orifice. Proper flame color is essential for indicating efficiency and safety in gas appliances.
