        Neil, correct, BUT, you can  orient it temporarily so the
adjustment is pointing down and the vent  horizontal.  It will not be a problem.  I
have done this many time and  currently have it that way on my van as I too
am testing different propane  pressure settings to see what effect it has on
the fridge operation.  I  have a fairly new, one year I think, Marshall
Brass 290 and have now screwed in  the adjustment screw two full turns and the
fridge seems to be operating  better.  I will know more after this weekends
adventures at BOTC.
