I'm finishing up my basement bar that includes a range with a grill.
These beasts tend to generate some smoke, so a vented exhaust is a
must. I've got a nice, beefy blower, but I'm concerned that the 20'
duct that will be installed above the suspended ceiling will leak
smoke and/or grease, particularly since the blower will be installed
at the hood, meaning that there will be positive pressure along the
entire length of the duct. How can I minimize this? 4" PVC would be
nice, but I suspect that it wouldn't be well suited to this
application (and probably not code). What are my options?


I'd buy an outdoor propane heater like bars use for their smoking patios in
the winter, and do your grilling outdoors on the BBQ. No matter what you do,
your 20 foot duct will be disgusting in no time at all, and you will
contemplate suicide.
