    This model is equipped with spark ignition. The pilot burner has a built-in thermal switch, to prove pilot ignition was successful & advance operating sequence. No flame sensor. Does the unit re-start automatically, or require powering off/on to re-start?

    Do you have a 3 wire pilot that looks like this?
