A thread in another newsgroup put a bee in my bonnet to ask this. I have a microwave installed over my stove. I wasn't there when the decision was made to install it as a recirculating vent. It's useless.
Don't get me wrong, I understand why they did it. The oven is on an inside wall and how to get the vent pipe to go to the outside, which leads to my question. Bear with me.
Do you think there is any reason why the vent pipe can't be a rectangular shape rather than round? If it was flat it woud go along the top of the cabinets and wouldn't be visible. I think.
But who knows, maybe that shape would cause a grease buildup or something I wouldn't think of. Is there a good reason why vent pipes usuallly are round?
Thanks. nancy
