In the case of an over-fueled burner, the excessive length of the flames can result in the quenching at the oven flame spreader or top burner grate even though the flame spreader and grate may be at the proper distance. Check for this before adjusting the burners.
When quenching occurs, (see Figure 3-20), the customer may complain of a chemical odor. This odor results from the Aldehydes being released from the flame as one of the by-products of incomplete combustion. Some customers may associate this odor with a gas smell, but the two odors are quite different. By examining the flame length between the burners and other components, and by looking for an out of place component, the cause of the quenching can easily be located.
