PRODUCT OPERATION

Refer to Figure 3-1 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 spark module w,
which produces high-voltage, low amperage 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 is ignited by the spark, and a flame is produced at each
of the top burner ports.
