When the preceding events occur, the BAKE
relay energizes, and its contacts close. This
provides an electrical circuit through the BAKE
ignitor and the BAKE valve to the neutral side
of the line*.
As electrical current flows through the BAKE
ignitor, it heats up. When the BAKE valve
opens, gas flows through the burner, and the
hot ignitor ignites the gas and air mixture, and
a flame is produced.
