I think IAMPO Will Not allow gas line in confined space even Garage How ever if the inspector or Local Authority in your state allows I agree that perhaps to run the gas line inside conduit and provide venting for better to check with your Local Authority .I’m running a gas line to a garage. Usually I’ll bring the line up outside and then go hard pipe into the building. In this case there is no floor poured yet. It would be much easier just to run the line right into the garage and pop up in the boiler room. In this case there is no floor poured yet.

I’ve never run into The situation of burying a gas line under a structure. I’m really not sure if it’s legal or not I’m going to find out about it on Monday. I’m thinking no. Are you guys allowed to do it where you are?
