Standing Pilot Ignition System, Operation

STANDING PILOT IGNITION SYSTEM

OPERATION

The ignition system provides heat, which is the third element necessary for combustion. Whirlpool ranges use two different processes to provide this element. The first process is a standing pilot ignition, and the second is an electronic ignition.

The primary purpose of a standing pilot is to ignite the main burner. Pilot assemblies consist of a gas supply tube and an adjustment screw that controls the amount of gas flow to the pilot.

To produce a pilot flame, gas is supplied through the gas supply tube (see Figure 3-23), and directed toward the pilot opening, or port. As the gas is available it is manually lit. The pilot flame is usually set to a height of approximately 1/4". This is accomplished by turning the pilot adjustment screw until the desired flame is produced (see the inset). The flame should have a distinct blue body.
