I have heard of venting a furnace out of the basement with a PVC pipe
instead of a chimney for a gas furnace (propane and natural gas). I
can't get natural gas where I live, but I want to look into the option
of venting the oil furnace out of the basement instead of using a
chimney (several reasone for not wanting to use the old chimney which I
don't want to bore ou with) . Is it at all possible to exhaust an oil
furnace out of the basement with a pipe (I'm guessing if the answer is
yes it would have to be a stainless pipe) undergound and venting into
the yard as is done with some gas furnaces? Also, could this setup be
retro-fit on an oil furnace that is about 10 years old, or only on the
newest more efficient oil furnaces?
