It's a condensing unit and is normal. Last winter the steam from the pipe looked as if there was smoke from a fire between our house and the neighbour's (and I was on the second floor)! It doesn't freeze, in fact I don't recall icicles on the pipe.

The spray that comes out of the second PVC pipe is water vapor. The exhaust temperature of your high efficiency furnace is lower than a "standard efficiency" model. The mositure in the exhaust gas is condensing out providing and is one of the reasons for the higher efficiency. I live near Chicago and during real cold times, I get a few icicles that form on my exhaust, not nearly enough to block air flow

One of the products of combustion of hydrocarbon fuels is water vapor.
