Hi,
A manual is available here that would have break-downs of the parts:

Yes igniter is flame sensor. If burner ignites then goes out shortly afterwards either the igniter is positioned incorrectly or there may be a spider web in the main burner oriface that is blocking the flow of gas to support the flame.
