Does not draw air at all. I've had the 900 cfm range hood for 2 months and it has been a total waste of money. No reply from Z-Line at all to my emails. 

Update. I got in touch wit Zline finally. They do not handle Canadian warranty. I  was instructed to order a specific part from Wayfair. I contacted Wayfair with the part number. After answering all the same questions I answered for Zline, a part was ordered. 3 days later it was canceled since it cannot be shipped to Canada!!!  I argued that Wayfair must find a way to ship the part to me. They have reordered the part and I am now waiting for it to arrive
