Operational Overview of Ignition / Re-Ignition System

Refer to figure 4-1

When the user turns on a burner the following actions occur:

The Mechanical Gas Regulator (Item 2) opens when the control

knob is pressed down.

The Ignition Switch (Item 1) is closed when the control knob is

turned to the 9 o'clock position. This allows power to be

provided to Electronic (Item 7) and the Transformer (Item 8).

The Electronic (Item 7) provides approximately 8 millivolts to the

activate the Thermocouple Solenoid (Item 3) for approximately 6-10

seconds to allow gas flow to the burner.

At the same time, the Transformer (Item 8) sends voltage to the

Ignition Electrodes (Item 4) to ignite the gas at the Burner (Item 5).

Once the Burner (Item 5) is lit, the Thermocouple (Item 6) is heated

and produces approximately 6-8 millivolts. The power from the

Thermocouple (Item 6) is monitored by the Electronic (Item 7) and

keeps the Thermocouple Solenoid (Item 3) open permitting gas

flow to the Burner (Item 5).

Should the Burner (Item 5) be extinguished (example: by wind) the

Thermocouple (Item 6) begins to cool down and the voltage being

produced drops. The Electronic (Item 7) detects the drop in power

and triggers the Transformer (Item 8) to spark the Ignition

Electrodes (Item 4) to re-ignite the gas. The Thermocouple (Item 6)

heats up producing 6-8 millivolts and the appliance resumes regular

operation.

In the event that the gas does not re-ignite (i.e. a defective or

contaminated Ignition Electrode (Item 4) the Thermocouple (Item 6)

continues cooling and dropping in power. Eventually the drop in

power can no longer keep the Thermocouple Solenoid (Item 3)

energized; this shuts off the gas supply to the burner (regardless of

the position of the Mechanical Regulator) (Item 2).
