    Proper gas connection

    Picture is a little dark. Saw this today. I love the black nipple for a flex coupling.

    You would think that the installer would at least put the nipple where it enters the furnace cabinet to make it look a little better with the doors on (as well as be somewhat safer). And I guess a drip leg was too much to ask for also.

    I agree. There was enough slack in the flex, he could have at least pulled the nipple through the cabinet!

    And what happens when the flex line rubs thru on the knock out hole ?

    Refrigerant is one thing but natural gas is a lot less forgiving
    I hope you correct that potential bomb.

    You are allowed to use ONE flexible appliance connector but it must not penetrate the cabinet. It can be inside the cabinet or outside but not through it. You can NOT splice two connectors as done here.

    A typical proper application with a flex connector would be piping to an approved shutoff, sediment trap, branch turns 90 degrees, ground union, steel through the cabinet, flex connector to the appliance valve.

    Why would you need a union when you're using a flex connector?

    i have never had an inspection fail because of not using one. i always thought it was a union. now i wonder if i was wrong and the inspector doesn't know any better.
