Whirlpool 4322452 manual Flame Quenching

The over-fueled burner has more of a normal flame structure and less of a blowing noise than a burner with too much primary air. The easiest way to determine whether the burner is over-fueled is to vary the air shutter opening size. If the flame length can be reduced to the correct size and structure by adjusting the air shutter, then the problem is not an over-fueled burner.

Top burners should have a cone length of approximately 5/8" (see Figure 3-18).

For L.P. installations and models without adjustable orifices, the orifice must be replaced with a recommended L.P. sized orifice.

Flame Quenching

Flame quenching occurs when the flame is cooled before complete combustion occurs. Placing an object, such as an oven flame spreader into the flame, will cool or quench the flame, resulting in incomplete combustion. The object interrupts the combustion process and releases the unburned by-products from the inner or outer cone of the flame.

The height of the surface burners in relation to the burner grates should always be closely examined and measured. If the burner is too close to the grate or too close to the maintop, quenching can result and possibly cause damage to the maintop.

Top burners can be bent out of adjustment easily by putting excessive weight on them, for example, by leaning on them. The distance from the highest point of the burner to the top of the grate should be approximately 3/4" (see Figure 3-19).
