    Gas sediment trap inside the cabinet

    I have never seen it done this way. Its a horizontal furnace, with the gas line entering from above.

    I see you are in PA... that method keeps the trap from freezing any accumulated moisture

    At least they put one one it.

    I can't fix it if it won't stay broke..

    You know, its not normal but its not hurting anything. I get more aggrevated when I see unions inside the cabinet or a gas cock located 20' from the unit or none at all on fairly new installs.
    If your not getting the results you desire then change. People change from either desperation or inspiration.

    WOW

    Never seen that before at all. Somethings just make me wonder.

    I always put the dirt pocket on the outside with the union and shut off.

    I just ran into that on a unit heater I changed. It had the union and gas cock inside the unit. The building was located 200ft from the main building and had NO shut off for the secondary building that I could find. Good thing it was low pressure, I had to remove the gas pipe going into the unit and install a new gas cock on the fly.

    Exclamation Read your gas code for proper terminology

    Actually, its not. It is called a "sediment trap". Look in your gas code. Drips are installed in the lowest point of the gas piping usually right inside the house from the meter and required only when you have 'wet gas'. Rarely required anymore. Now, everyone calls them "drip legs" or "dirt legs" but those are incorrect terms, similar to Southerners ordering a "Coke" when they want any brand of soda--generically speaking.

    The code does not prevent the installation of the trap from being located inside the cabinet but it is rather awkward. Cannot see it clearly but there must be a ground union joint so the unit can be disconncted and there must be a listed shutoff within 6 feet. As long as this pic is the actual orientation of the trap, it is acceptable.

    At least it is at the point of direction change. Amazing how many are in a horizontal run.

    Maybe the installer was short one 1/2 inch elbow, and came up with a creative solution....
    Technical incompetence is NOT a sales tool....
