    Yeah, the code here is that the entire flex must be visible and easily accessible. That's a definite code violation and improper use of a flex.

    all mechanical codes state that UNIONS must be readily accesible!!!

    gas flex is a union!

    and flex lines can not pass thru cabinets.

    Hmmm... Seems to me an install issue, not a product issue.

    While we are on the subject of flex gas hoses... I am glad they are coated now.

    We mostly use 18" flex gas hoses as a 'connector' between the shut-off and the pipe coming out of the furnace (drip leg is on the pipe coming out of the furnace). They are nice for this application. IMO flex gas hoses should NEVER touch anything... NEVER!

    Here in CA, or at least the Bay Area CA, these gas flexes are a requirement rather than an option. It is part of earthquake safety. So it is not optional to hard pipe it all the way. Those would be called as a safety hazard by the City inspectors.

    correct
    as long as they do not pass thru a cabinet and are readily accesible.

    we usually run all the black iron in the furnace cabinet and stub out a couple inches, then flex and then gas cock and drip leg.

    Correct, it ran thru the furnace cabinet directly to the valve, with a loop in it because there was too much extra, it vibrated against the cabinet and created a leak.

    We never use flex connectors. They do have a place, on a stove or drier.

Hard to tell from the pics but if the flex was damaged down by the gas combination valve, it could be sucked up into the return where, once ignited down by the valve, could explain the burn pattern.

    I agree with Pacnw: instead of vilifying the product, condemn the improper installation and mis-application of the product. Used properly, they have an excellent track record.
    help me understand your post a little.

    As I look at the photos I think the furnace is the metal you see and not a duct run.

    Are you saying that neither a shut off, flex/union or piping can be in that area because it is a duct run and therefore when closed it is not accessible AND/OR it may leak.

    OR

    Assuming it is just the joist space and the furnace cabinet you see, the piping and shut off are okay, but the flex is the only thing wrong(run through the cabinet).

    Yes the flex is one thing that is wrong. The vibrations from the furnace can loosen or cut the flex. It is supposed to be hard piped from the gas valve and out the cabinet. Typically you make a drip leg right after the hard pipe exits the cabinet, and run the flex off the drip leg. But I am not sure a drip leg is required everywhere. It definitely is in my area.

    The shutoff valve has to be in a open, easily accessible area. It can't be behind a door or behind any equipment. If you are standing in front of a water heater or furnace, you should be able to see the shutoff valve easily and shut it off without moving your body.

    This I get, thanks.

    It was hearthman's post that I was wanting clarity on.
