Is it ok to Modify Gas Pipe Line behind the Gas Range in this way

tester22 · January 7

Hi guys, I don't have Gas Shut Off Valve easily to Turn Off Gas in case Gas Leak in Emergency situation, so I want to modify the black Iron Gas Pipe behind the Range in this way, so that Shut Off Valve install behind the Stove 4 or 5 foot above and every one in Home easily Shut Off in Emergency.

I am worry about this is 1/2" Pipe line, if I make this many Bends in Pipes, then it is going to decrease GAS PRESSURE, so I am not weather is this good idea or not.

Please make me correct, still can I get same good Gas pressure like 7 WC (water column), after modifying Gas Pipe line behind the Range or my Gas Pressure decrease and it is not good idea.

Let me know please.

Thanks

Adding 2 90's to the piping should not affect your pressure.

Do you have an open basement under the range? If so you could add a valve down there and leave the one behind the range. That worked out for me in my house.

If the range is not on an outside wall, then you could cut an access panel behind it and cover with access door. That would be flush to the wall and paintable.

I don't have open Basement, I am in Town House.
If it is not necessary in case if Gas Leak, then this very heavy Range unable to Move to Shut Off Gas, so what other option to Shut Off Gas, if I not make this situation easy.

I know out side House, there is a City Gas Meter is there, and City can Shut Off Gas with Tools, but ordinary home Peoples they don't know there is a Shut Off Valve out side House and need a Tool to do that.

So I am thinking.

The valve fits into a notch in the bottom of the stove. With that piping you will not be able to push the stove all the way to the wall. If that is a concern?

Sometimes pulling out the bottom drawer give you access to the valve. If you have long arms🤭

Ok got it, I think no need to Modify and its look UGLY & when selling Home it can be problem,
may be Stove not go in completely.
and yes when we pull bottom drawer, I can see Shut Off Valve, but it is very very difficult to Turn Off from there, because Hand not reach there.

Thanks for the Help.

Shut off valves are for service- not emergencies. If there is an emergency, evacuate the building without turning off lights or switches and call 911 from outdoors. The emergency shutoff is at the meter. If you have an indoor meter let the pros handle it. The code does not expect you to reach into a combustible vapor cloud to shut off gas. To reach over a burning stove is even more dangerous. If you really feel the need for an accessible shutoff, pipe a 'key' valve in the toe kick of the cabinetry. These use a 'T' shaped wrench to a 1/4" square valve stem down in the valve, they have a round brass escutcheon plan that threads onto the valve body. You can get them inline or 90 degree and they're 1/2" NPT. Many people refer to them as 'Dante' valves but that's actually just a popular brand.

You are way over thinking it.

Most gas meter shutoffs do not require special tools. Usually it just takes large crescent wrench on the flat tab.

I've never seen a gas stove / range with a shutoff you could get to without pulling it out first.
It's only there so you can change the appliance without turning the entire building off.

You’re way too concerned about a failure in your gas appliance. Will you also install a shutoff upstairs for your furnace or your water heater? See my point?

This is for entertainment purposes only.

This picture was taken a few years ago on the way to Mississippi from NE.
Could be a hotel in Missouri.
I am thinking that insurance or local fire marshall required tools at the gas meter to shut down the system.

I believe that these small crescent wrenches would be challenged by the meter valves, but the AHJ must have been satisfied.

High pressure into the hotel.....BTW, the ball valve on the left would shut the entire system down.

Hi there, when I pull out Bottom Tray of my Gas Range then I can see like this below. So what is this WHITE KNOW inside it, and is there any way I can Turn OFF Gas in case if I notice any Gas Leak in this way.

And what is the name of this WHITE KNOW Bottom of my Range inside it, and at this place my Hand can reach.

please let me know....Thanks

Its not a knob. Its a cap. I don't know what it is for.

The shut off valves for appliances are service valves, to be able to turn off the gas to service the appliance. They are not emergency or safety valves.

If you smell gas or otherwise have a gas emergency, evacuate the building and call 911.

These units are usually supplied with convertible NG/LP regulators. Yours is factory set to NG.
You only touch that if you were to convert to LP, which will probably be never. So don't touch it ^^
