    I recently ordered a new gas log set and the supply line is not long enough so I need to order a longer line. My question is what is the difference between low and standard capacity? My fireplace is natural gas.

    By Collin C. - NFI Master Hearth Professional on January 14, 2014

    Low capacity lines have a 1/4 inch inside diameter and are limited to a BTU capacity of 40k to 30k, depending on the length needed. Standard capacity lines use a larger 3/8 inch inside diameter and can handle an input of 100k to 70k, depending on the length. Depending on the BTU capacity of your gas logs, the low capacity line may not be large enough.

    I'm looking for a stainless double disconnect box for propane, what would you recommend?

    My apologizes, but we do not carry such an item. You will likely need to inquire with a plumbing shop that sells specialty gas fittings.

    I'm looking for the gas line that actually goes inside a fireplace to disperse the flame. I'm not sure exactly what it's called though, so I'm having a little trouble finding it.

    Just to clarify, would this be something that is used in a brick fireplace or a manufactured (metal) fireplace? I am also a little unclear about the part you are referring to. We have gas burners that usually are covered with a thin layer of sand or embers that are used to fan/disperse the flame and give a more natural looking appearance.

    I have a Waterford gas fireplace (made in Ireland) which has a flexible gas line that is too small for a 1/2" pipe thread and too big to fit a 3/8" pipe thread. Any suggestions as to what to do?

    If possible, disconnect the line from the appliance, and visit a local HVAC supply or plumbing supply store to identify the correct adapter or fitting necessary.

    I am having difficulty making my gas line connection from the burner pan to the gas supply stub. The burner pan is in the middle of the fireplace but I have to go up, make a 90 degree turn to the right, and then go up again and make a 90 degree left back to the gas supply stub. What should I be using instead of the flexible tubing? What should I be doing to make this connection?

    Your application is the ideal scenario for a corrugated flexible supply line, such as the Hearth Products Controls Standard-Capacity Black Stainless Steel Flex Gas Line - 12 Inch. The line would allow the flexibility to run out of the shutoff valve and behind the burner, curving around and back to the side connector on the burner pan.
