Re: Exhaust in upright position?
As they said on Monty Python, "And now for something completely different".
I admire your willingness to experiment with exhaust mounting. One of those 3/4" copper flex hoses from a water heater (Home Depot or Lowes) could be used for an exhaust extension to direct the fumes as you desire. Question everything.
