range hood exhaust routed down into crawl space
Anyone have their range hood duct so that it sends the exhaust into the crawlspace beneath the house?
Our house is pier and beam foundation with about 2 ft high crawlspace beneath. Routing the duct exhaust behind the hood downward instead of horizontal would give us a lot of extra space in the closet where this duct work needs to be installed. (cross-section of duct is 3 X 14) - contractor says that range hood exhaust is "friendly exhaust". Of course a screen would be added where it reaches the area below so little critters couldn't enter. I was mainly worried about whether grease can travel 4 1/2 ft to escape and coat the underside of our house.
Also wondering about maintenance - do these types of ducts need to be unassembled and cleaned periodically?
