> Although the blower is designed to mount with the wheel shaft horizontal,
> the assembly can be placed flat with the plenum on the rack-top, and the
> hot air gets sucked up and blown out through the circumference of the
> wheel. When placed this way, the plenum box is about 12x18x4" tall. The
> blower assy adds 3".
