Would this type work if it was 90 through the wall instead of the roof?

Hi forge722,
  A furnace contractor friend of mine said every 90 degree bend reduces
the flow by 50 percent.  The answer would be sure, but use a larger
diameter pipe, assuming my friend is right.  It makes sense to me.
We changed the location of a bellows once from firepot level to hanging
from the ceiling, and the blast was cut considerably.  We traded the
2" pipe to 3" and it went back, (almost) to normal.  Might consider 
larger pipe.
