COOKTOP OPERATION

The range ships from the factory ready for use with natural gas.
Conversion to LP must be performed by a qualified installer or
servicer. An LP conversion kit ships with each range, and the kit is
also available as a service part.
Each of the sealed surface burners is controlled by a gas valve
attached to a common manifold pipe. The spark igniter switches are
assembled in a continuous harness, and each switch fits onto a
control valve. The valve shafts extend through the front panel where
the knobs are attached.
Each burner has an electronic igniter; there are no pilot lights.
When the knob is pushed inward and rotated clockwise to the
position...
 Control valve opens and gas flows from the manifold to the
burner tube into the jet holder assembly and through the
orifice, where it combines with air to create the mixture
necessary for combustion.
 Spark switch closes and sends 120VAC to activate the
electronic spark module.
 Spark module output sends 14,000VDC to the igniter
(electrode) through the spark wire.
 Gas and air mixture at the burner head is ignited by the spark
created beneath the grounded burner cap, causing the burner
to ignite.
 If the flame is lost while the knob is on, a flame-sensing circuit
re-applies spark energy at the burner to re-ignite the gas.
