I have no issue with the exhaust pull, since I have thec1200cfm fan pulling through a 10 inch duct. My problem is that the motor to raise the unit when turned on is too weak to raise the unit. Called service out, he called factory, they said it must not be straight and is binding. We removed the cooktop and made sure the vent was free floating and it still does not work. It will work if I take the filters out, they are quite heavy. Clearly the motor is too weak, but company will not stand behind it. DO NOT BUY CHEAPLY MADE EXPENSIVE PRODUCT
