The reasoning is that it requires outside air. Basement air is a no-go. It can go down through the floor if it then takes a 90º turn to get to the outside wall for the intake. It can also draw from a fully ventilated, open crawlspace.I ordered the Drolet Escape 2100.
it arrived a week later ( Today)! It is still sitting on a pallet in the yard, and I might even burn it out there a time or two to set the paint.
anyway, I ordered the Outside air intake with it.
instructions say to NOT go down through the floor, but go out a wall?
what is the reasoning there?
