No incident, no one hurt Made Mar 6, 2024, sent to the company Mar 15, 2024, published by CPSC Mar 29, 2024
The product, in the report: Broan model 634 vent cap and other similar models. With the vent hood turned on a significant percentage of the flow comes back into the attic due to the gap between the vent duct and the roof. Without the range vent hood turned on natural draft flow from the living space to the attic would be increased since the roof cap damper is not reducing the flow. The instructions indicate to make the hole in the roof approximately 1/2” larger than the duct. No instructions are given to seal the gap before installing the roof cap. I contacted the manufacturer and they indicated that the same design has been installed for 3 decades. Similar product made by [REDACTED] has a stub duct that eliminates this problem. I would assume that thousands or tens of thousands of home owners have significant range hood exhaust flow into their attic due to this issue. This violates residential construction code and presents a fire/safety hazard.
During investigation into condensation dripping in attic from a range vent hood duct we noticed that the roof cap design and installation guidelines would permit direct venting of the range hood into the attic.
