Downdraft cooktop ventilator

Anybody ever see a downdraft cooktop ventilator vent into the crawlspace of a maufactured home ? Today I saw my first…

Yep, and it’s improper.

Jeff, Thanks for the reply. First one in 11+ years for me. I called it out!

All exhaust fans should go directly to the outdoors, not the attic, crawlspace or just pushed into the vented soffit with hope that the exhaust air will actually get outdoors!!

IRC M1501.1 Outdoor discharge. The air removed by every mechanical exhaust system shall be discharged to the outdoors. Air shall not be exhausted into an attic, soffit, ridge vent or crawl space.
