    Yes, it was a GE Premier 36" Gas Cooktop, it was already in place when they bought the house so it may very well have been installed without a permit.

    My question is

    “”Now the contractor is telling her, the
    Inspector states the new cooktop/vent is in some kind of code violation and we should
    replace the new cooktop with the original Premier style unit. “”


    Both open flame devices

    So is the inspector changing the violation

    Or misunderstanding of original violation??

    So do an online search for the install and specs on the new vent

    See what it says

    Maybe post a link to it

    Has the code or manufacturers manual changed since the original cooktop was installed?
    Where does the vent daylight too, is it below the finish floor?
    How is water prevented from entering from the outside?

    MH, thank you for an excellent breakdown of the calculations.

    That information was second hand, coming from the GC. It didn't make sense to me and is why I decided to go directly to the inspector.

    The cooktop/vent are located on an island in the kitchen. The duct runs under the slab (6" PVC) outside it turns vertically to about 18" above grade and is protected by a rain cap - this is all to code and is not what the inspector is finding fault with.
    His specific statement was that the vent was not to be used with an open flame gas cooktop per the manufacturer's installation manual.
    I suspect he may have grabbed the manual from the original vent (which was a cheap model). The previous homeowner left all the manuals in a kitchen drawer so it is a possibility.
    I have contacted GE directly and they told me they will do a little research and give me a definitive answer shortly - I wanted to do this to be sure before I confronted the inspector again...I'm a mechanical engineer, and as you may know, we're a pretty anal bunch. Funny thing, my company holds a mechanical contractor's license in the State of Florida.

    See pages 9 & 12 where installing the vent with the Monogram cooktop is specifically addressed.

    Why don't you detail your proposed installation on your company's letterhead and affix your mechanical engineer's stamp. Most reasonable AHJs will accept an engineer's detail over any prescriptive regulation. Of course, if you are dealing with an unreasonable CBO this may not work.

    GE Tech Support sent me a definitive Email that the downdraft vent is absolutely compatible with the Monogram cooktop so come Monday morning I will be sending the inspector an Email with all the evidence I have collected, I can't see how he will not sign off on the installation given the information I have...we will see.
    BTW, Tech support also questioned where he was getting this information from and stated that he was mistaken.
    Fingers crossed.
