I need to convert a range hood that is venting both up the vertical duct and into the room, to just venting up to the duct. In the photo, the room vent is seen on top of the hood.

I have looked inside at all angles, and the squirrel cage fan is plenty strong enough to vent only up the duct. There is an assembly connected between the outlet of the fan to the top of the hood that directs some flow through the vent in the top of the hood into the room. But I don't see any way to close it - at least without taking things apart. No manual and searching the series number turned up nothing at www.broan.com.

Seems odd to me, but in any case, anyone ever seen this type of setup before?

Thanks buddies!


I bought a new vent hood and it came set up to do up the vent and out
the front. It came with a plastic insert that you put over the front
exit if you wanted it to go up the roof vent. As this was an existing
house with a roof vent I hooked it to the vent tube and installed the
plastic cover. I could still feel air coming out thru the plastic
cover area. I suspect you are missing whatever sort of cover it came
with originally to cover up the inside vent area OR it's already
installed and just leaks some air like mine did. How strong is the
air flow out the inside part? I just left mine with the leakage since
it's in a rental. If it had been in my house I'd have figured how to
put metal duct tape over it on the inside to really seal it up.
