From what I've come to understand- the electric mode gets the chimney
warmed up sufficiently so as to get the convection flowing so that propane
won't pool and flood the combustion chamber and a also a proper amount of
oxygen (or atmosphere at least) is able enter.  Basically, it gets the
juices flowing well enough for the propane to just jump in.  Think of DC
operation as the guy who warms up the crowd before Regis comes on stage.
        (I'm sure Mark Dorm has a much more brilliant analogy.)
