Whirlpool 4322452 manual Sealed Burner, Flow

Refer to Figure 3-33 for the following sequence.

SEALED BURNER

When a main burner control knob q is turned to the “lite” position, the gas valve r opens, and gas flows through the pressure regulator s into the manifold t through the open valve. As gas passes through the valve and its orifice, it is directed into the venturi u, where it mixes with primary air to create the proper mixture necessary for combustion.

At the same time, line voltage is applied through the ignitor switch v, to the ignitor spark mod- ule w, which produces high-voltage pulses to all of the spark ignitors x. The pulses cause a spark y to occur between the spark ignitor electrode, and the grounded burner cap z. The gas and air mixture at the burner head is ignited by the spark, and a flame is produced at each of the top burner ports.
