阅读本文和所有评论后，//m.etiketa4.com/article/how-to-provide-makeup-air-for-a-wood-------，我现在非常关心安装在我的壁炉上的化妆通风口，这是一个连接到右下角的4英寸通风孔（请参阅图片）。我认为壁炉上的阻尼器基本上是关闭/打开该通风口，但事实并非如此，现在听到这可能是火灾危险，而壁炉确实只需要15-25 CFM，我想我会断开它的连接……

My new house will be very, very tight (still need to have the blower door test), I’m thinking of converting this vent as a hood range makeup air with a motorized damper and inline fan, controlled by a sensor on the range chimney. I know 4″ will not provide a lot of CFM but not intending to have a powerful hood range either. The fireplace is maybe 15 feet away from the hood range. Do you think this is a good idea? What about using the same makeup air vent for the dryer (I get I could not use both the dryer and range hood at the same time)? Maybe also add a switch nearby the fireplace to open the damper just to provide some makeup air when starting a fire instead of opening a window? Any expert opinions are welcome!
