  • Gas Stove hood

    I have seen stove exhaust hoods in both configurations:

    1. typically a 6" round duct vented to the roof with a rain shield
    2. a 6" round duct with a damper to keep it closed when the fan is not on

    what is the preferred configuration???

    I look at the range hood as just another hole in the house allowing hot or cool air a means to
    escape or enter.
    I'm in Arizona so cold is actually not a problem nor critters entering unless you count
    scorpions!

    Scorpions?... really? How the hell do you sleep at night?

    Mine runs horizontal thru the wall with a flapper. It vibrates loud during a windy day. Used to sound creepy but now its kinda soothing. Most houses here are two or three stories so roof penetrations are rare.

      Any outside venting will have a backdraft damper someplace. Fart fans, microwaves, most range hoods will usually be on the appliance, dryers and larger fans typically on the outside of the home. Both methods "should" have protection to keep critters and large debris out.

      I don't really have a preference, both potentially howl with the wind during storms, but internal flappers you can hear slapping when the wind blows.
      We don't have preventative maintenance around here, we have CRISIS MANAGEMENT!

        Of course this is all "after the fact" and has been in service almost 5 years before
        I thought about it.

        I have a Nutone brand range hood stainless steel, halogen lights, etc....

        It has a 6" round duct running 8 to 10 feet straight up to the roof.
        It has a rain shield over the top but no damper what so ever.
        There is a critter screen at the top opening which is accessible
        to allow washing every year or so to eliminate a grease fire!

        The duct connection to the hood is a straight push on and use two zip screws.
        no damper there either.

        At the range end the hood has two removable grease filters and when you look up
        you see the plastic impeller of the air moving fan.

        When I do the smoke test [Dominican cigar smoke] the smoke does travel upwards and no
        leaks.


        Shall I leave it alone? [if it ain't broke don't fix it] -or-
        should I investigate adding at the roof top some sort of damper?

        Oh..this is a gas stove and I'm the cook
