Whirlpool 4322452 manual Not Enough Primary Air

Page 30

The inner-cone combustion process will occur in increased levels, and will release more of the harmful by-products, CO and Aldehydes. The level of secondary air will no longer be enough to convert these chemicals into the safe by-products CO2 and H2O, and there will be higher levels of dangerous chemicals released into the room.

NOTE: It is normal for the burners without mixing tubes to have blowing flames during the first minute of operation. When the burner is cold, primary air injection is increased. Once the burner heats, the injection of primary air is reduced and the flames settle.

Not Enough Primary Air

The reduction of primary air slows the burning process and results in the inner cone rising higher in the flame. Less burning takes place in the inner cone. A larger amount of the by-products that would be consumed in the inner cone pass into the outer cone.

The size of the outer cone is also reduced by the lack of primary air. The outer cone cannot consume the volume of by-products flowing from the inner cone. A percentage of these by-products flow into the outer envelope where the carbon content of the by-product is burned, causing the flame to have yellow tips (see Figure 3-16).

Over-Fueled Burner

Over-fueling of the burner can be caused by one of three common causes:

Excessive gas pressure entering the burner

The BTU rating of the gas can be too high for the burner

An oversized gas metering orifice

It is difficult to recognize the difference between an over-fueled burner and too much primary air. In both cases, the burner flame length extends too far off of the burner (see Figure 3-17).
