| I need to move my natural gas stove during a kitchen remodel. My question is this: can a gas flex line be used to connect to the black iron pipe in the basement,and then come up through the kitchen floor between the stove and the wall. One complicating factor is that the flex line would have to pass right next to the heating duct before coming through the floor.
I have read a few statements online that the flex line should not come up through the floor, and that it should not pass next to the heating ducts (due to issues with lightning strikes), so I think the flex line is probably not a good idea in this case. But those statements were a few years old, and I really don't know for sure if they are correct, so I would greatly appreciate a few more (hopefully knowledgeable) opinions on this issue before I proceed. Thanks in advance. |

| There are bonding requirements for CSST developed to eliminate issues with lightning. CSST can pass through the floor, it may need some protection. If you are talking about a flex whip it should not pass through the floor. |

| In my area, the longest run of flex you can have between the black iron pipe and the stove is 6', there must be a readily accessible gas shutoff where these two join, and the shutoff must be in the same room as the stove. I agree that the best thing to do is to extend the black iron pipe to a location near the stove: this will minimize potential problems with the more fragile flex getting damaged at some point. You should also check with your local code people to see what is to code in your area. When it comes to gas, it's wise to adhere to code requirements. |

| You have to check with your local code. In my area we are not allowed to have any flex line. We have to use BIP or brass pipe all the way to the appliance regulator. |

| In NC, copper tubing can be used for gas lines. Fittings must be flared or silver brazed. |

| "In my area, the longest run of flex you can have between the black iron pipe and the stove is 6', " Short flex connections are not the same as CSST. In areas that allow CSST it can be used for almost the entire job. |

| Thanks for your replies. After consulting with 2 licensed plumbers (gas makes me a little nervous), it turns out that the best position to put the line is actually right through the air return joist bay, and flex line is apparently not allowed for that, so it will have to be the hard black pipe, regardless. Thanks again. |

| joe71- Thanks for the followup. It's always good to know how these things turn out. |
