    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?
    By Collin C. - NFI Master Hearth Professional on January 10, 2013

    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 am needing a 3/8 female (on both ends) natural gas line for my vented gas fireplace. I would like it to be about 24 inches long, black preferred. Can you recommend a product?

    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 hit a gas connection (pictured) with a lawnmower. I used a hacksaw to cut through the horizontal pipe and now am left with 2 vertical 1" pipes. Is there a type of flexible connection that I can use to make a repair? The pipe runs under my patio and through a stone wall to the actual fire-pit, so there is no easy way to get to the burner and work backwards.

    The use of flexible gas connections may not be allowed in your municipality and you should contact a local plumber or gas fitter to determine what may be used outdoors, as National Fuel Gas Code is only the standard when adopted locally.

    Can I connect (2) 18" connectors together? I have a vent-free gas log system, but my gas pipe is on the left side not the right. I have not been able to find a connector long enough.
    By Will M. on December 19, 2016

    You may absolutely use two flexible connectors together when one is not long enough.

    I'd like to connect the two pipes seen in the first picture. They look to be 1/2 pipes with 3/8 90 degree fittings on them. The fittings will not come off. What do you have that will allow me to connect 3/8 male to 3/8 male in a fireplace that's used to burn wood. The gas is just used to start the fire. As you can see from the second picture, the prior owner connected them with a short line which looks like it was aluminum. It seems to have melted, which I discovered when I cleaned out all of the soot in the fireplace.

    The connector we carry that would work for your installation would be the Hearth Products Controls Brass 1.5 Inch Gas Pipe Swivel Connector - 3/8 Inch Flare Ends.

    I recently purchased a stainless steel 36'' gas line to connect to the gas fireplace pan inside the firebox. Is this product designed to withstand the heat inside the firebox?
    By eFireplaceStore on December 5, 2016

    The flex connectors we carry are indeed rated for installation within a firebox.

    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?
    By Chris C. on June 17, 2016

    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.

    By Nathan from Katy, TX on January 15, 2015
    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?
    By eFireplaceStore on January 15, 2015

    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.

    I'm attempting to replace the log lighter pipe and I'm unsure of which way to turn the existing pipe to loosen it from the gas supply line that it connects to at the side of the firebox. Please advise.
    By Will M. on May 30, 2017

    You should turn the pipe to the left or counter-clockwise, but only after after the manual shut off valve has been turned to the off position. If you are unsure about this, only a licensed plumber or gas fitter should remove or install any gas fittings that are currently in place.
