THEORY OF OPERATION

Refer to the illustration below while you read
this description.
When a surface burner control knob is turned
to the "lite" position, the gas valve r opens,
and gas from the pressure regulator s flows
into the manifold t, and through the open
valve. As gas passes through the valve and its
orifice, it is directed into the venturi u, where
it mixes with 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 module w,
which produces high-voltage pulses to all of
the burner ignitors x. The pulses cause a
spark y to occur between the burner ignitor
and the grounded burner cap z, which ignites
the gas and air mixture at the burner head, and
produces a flame.
