Guide :Kitchen Ranges : Savona ZSA-M90S Kitchen Hood

Flap valve and noise

1. The hood is shipped with a 6 inch round flap valve, presumably to keep outside air from blowing into the kitchen. The manual makes no mention of this part. Is installation recommended? If so, just drop it into the opening at the top of the hood? 2. The blowers make an unusual noise, hard to describe, audible at low speed only. Am wondering if there's a bad bearing, etc. Where do I take the unit to have it checked out under warranty? Live in Seattle, Washington.
