Gas Outlet Box

I'm reworking my kitchen, and part of that is switching from an electric cooktop + wall oven to a freestanding gas range. Originally, the plumbers wanted to run a line up through the floor after the cabinets were installed, but I've never been a huge fan of something like that. Well, I ended up finding these gas outlet boxes, and I'm wondering if there's any reason why I shouldn't go that route? (To note, my existing lines are 3/4" black iron pipe, so that should be the one that I need.) I did notice that there are fire rated variants, but I can't seem to find any codes that specify whether or not I need to have one.

that should work. you probably have 1/2 in pipe, which is closer to 1 in outside dia and standard in residential construction. The thread is 1/2 in NPT. be sure to see if the stove will work with this, as some are built expecting the gas to come up from the floor and do not have room for the pipe sticking out of the wall. We changed ranges in our past home and had to swap the electrical and gas lines from one side of the hole to the other for the stove to fit correctly.

I believe I have 3/4" pipe based upon this picture that I took a week or so ago:

I wasn't sure what size it was until I saw the 3/4" on the ball valve.

As for making sure that it fits, I've been thinking about that a bit too. I do have the range already in my house (sitting in my family room), so I can look at the back to get an idea where each part hooks up. If I had to guess, would it be better to install the connector (electrical or gas) on the opposite side of where it connects on the range? I figure that the cord/pipe will need some space, and forcing it to go from one end to the other would do that.

Try this link to determine your pipe size: http://products.anssteel.com/viewitems/steel-pipes/sch-40-bare-black-standard-steel-pipe?

Get the outside diameter and compare the chart to determine for sure what you have.

One a side note. 3/4 pipe is probably oversized for a typical stove or range (my boiler takes 3/4 inch pipe). Unless the distance from the gas meter is very long. Typical ranges, 1/2 pipe is mostly sufficient. Look at the back of your stove to determine what size pipe you actually need and install that size valve behind.

I do like those boxes though. Neat and fit into the wall. I'd probably insert a short nipple and elbow pointing up to screw the flexible tubing to.

on my range, the back is flat. we had to have the gas outlet at floor level to go under and to the right front corner to hook up. the electrical hook up had to be on the left side about 10 inches up to get it to squeeze in. it all depends on how the range is set up.
