I'm sure this exact post is on here, but I am feeling pressure from my builder to get exact dimensions for a fireplace quickly and need to decide what kind. I live in Texas and it will run off propane, I have been reading about the condensations problems with the vent free. Which do you think is better a direct vent or vent free? It seems to me vent free would still have to vent somewhere, but that is what my local installer sells and swears by. Thanks.
