    True! In commercial-institutional kitchens in schools, prisons, and high rise structures there is often a requirement to have the ANSUL system tied to an electrically (fail secure) powered main gas shutoff solenoid valve that kicks off the gas valve if the kitchen vent hood ANSUL fire suppression system triggers.

    That fuse wire under the vent hood will often have a cable to the spring loaded gas valve and ANSUL unit.

    The fire suppression gas valves are in almost every restaurant that has a large 60+ person seating area.

    High pressure gas pipe must be welded solid flange pipe and painted yellow in false ceiling areas to code.

    A gas shutoff valve is needed so the furnace can be replaced without disrupting other gas appliances on the line.

    All gas appliances need their own shut off valve. So yes.

    Fire code in jurisdictions where there is one generally requires a manual shut off at each gas appliance.

      IRRELEVANT. Multiple shutoffs are OFTEN required.

    You don't get it? How could you understand if it's something that somehow became a fad?

    She swings the leek; and talks really weird- looks really really hyper;and it's just absurd...

    It's okay if you think it's really weird. that's the point-- it's just really weird.

    It repeats on loop again and again until you get sick and press STOP.
