Again thanks to all for the great info. I'm proceeding with a 10kw
Guardian. I can offer some small info back to everyone: the installer told
me that their units are not guaranteed to start if the temperature is
below -20 deg. F. I asked him about the poster who had a freeze up and oil
blow out and he said it was probably your PVC valve that froze or clogged
because of cold. He offered a solution for us who live in very cold
climates. He has customers that put a small strip light in the cabinet which
is more than enough to prevent the problem.

Or at least one genset manufacturer sells a cold weather start kit which
consists of an electric blanket for the battery and and oil heater for the
motor. It automatically comes on when the temps drop so you aren't running
needlessly during the day.
