Hi Daniel,

It appears that you experienced the very same issue I'm having. The output vent blows a bodacious amount of air. The intake over the oven, however takes in almost nothing. The vent into the kitchen is also sucking in just a wee tiny bit.

The fans are oriented to blow outside via the back of the unit. According to the installation manual, everything is properly in place.

What was your solution?

Cheers,

-Patrick
