Navien CH240 drawing intake air from basement?

in THE MAIN WALL
Just visited a new client of ours to take a look at their new heating system install. They have a Navien CH240 that is drawing intake air from the basement, instead of the usual outside air intake.



The manufacturer does include an option for non-direct venting, although it seems insane unless absolutely necessary (of course, in this case it's not necessary at all). In this case I believe the old dusty basement would quickly void the warranty.



Anyone else seeing this?

    Besides

    the possibility that if the house is tight where will the unit gets it's makeup air from then after inside air is exhausted ?  Not a good install in my opinion .
