Hello,
Hopefully this is posted to the right place.
I'm running a 10" sheet metal duct out the roof, for an island range hood.
Is any separation of the residential kitchen range hood exhaust duct required from combustible materials? I believe part of the reason flex ducting is not used, is due to potential fire hazard with the range hood, so just want to verify that as I go through the roof I don't have minimum separation requirements from combustibles.
Additionally, do I understand screws are allowed in this duct, and minimum of 3, evenly spaced?
Lastly, the duct slides up into the roof cap (about 3"). Is any sealing or attachment required there? Both would be near impossible, though possibly from the inside for both.
Many thanks!
