Capping gas pipe?

[LGTWhit]

Having a contractor install our new E2 as soon as we cap off the propane line. I assume I can do this myself. Turn off gas, wrap pipe threads with Teflon and cap. Turn on gas and retest spraying with water??

 

[Big papa]

I would expect that you can but notify your gas co just to be thorough

 

[LGTWhit]

Well, found out where to cap in basement and shut off valve. Next is to find a cap

I can't go to that link says there's an error but I would think you could get a cap at lowes hd or even from ur gas company

 

[LGTWhit]

Can you see pic now? Going the Depot now. I assume caps are pretty standard fit

I had an LP pipe that penetrated the firebox to feed an LP insert. Unfortunately the pipe stuck a bit too far into the firebox for the new pellet insert. I capped the LP line in the basement. Afterwards I applied a cheap angle grinder to the problem pipe in the firebox. Afterwards, I filled the pipe with refractory cement. It is NEVER easy.

Inside of the copper nut on the yellow pipe there are sealing washers and rubber o rings. take care to not loose them, I would suggest capping or plugging both pipes to keep dirt etc. out. Never know when something might get hooked up again.
Also use Black Iron not galvanized fitting and Yellow Teflon tape .
There should be a main gas shutoff outside on the meter to turn the gas off for the entire house so you can work on it.

It's not a difficult task but, if you are not comfortable doing it, you probably shouldn't.
The probability of failure is low, but the consequences of failure could be unacceptable.

Yes, like that. I couldn't just cap it because the pipe would have been too long. I suppose I am committed to solid fuels now, but I don't see that as a problem. We only have LP ($$$$) and natural gas won't be coming down the street in my lifetime.

Man I wish they had that csst when I was learning!
I wouldn't worry about "saving" the gas tubing. If you go back to gas, that csst is small cost.
I would leave about a 1-2" stub out of the plastic conduit that the csst was run in. That's required and annoying to replace.
You will need to cap in the "basement" or where that prior picture was taken.
A pro trick is to tie a 2x3" paper string tag to any abandoned & capped end describing the status and where the other end is.

Now you see why I asked if your installation quote was "inclusive of everything".

PS. Please do not let your new pellet insert ever get this dusty.

The only thing he told me to do is call local gas company to cap off line. Our local gas company are complete dicks (osterman fuel) so I'd rather do it myself. I'm gonna call him to see if he wants me to cut the line or if he will do it, and then we are golden!

Anyone have any better ideas on how to brake the iron pipe free from the fitting. I've used two vice grips and iron pipe just spins

Try two pipe wrenches facing opposite directions. Squeeze the handles together.
If that doesn't work, apply heat (torch) and break them loose with the wrenches while still hot.

 

[LGTWhit]

Or I could probably break free those brass fittings from each other and use a bigger cap

 

[CaptSpiff]

What do you mean the iron pipe spins?????

Assuming the iron pipe is the supply and the csst tubing is the appliance side, the iron pipe should not be "spinning". Now you got me worried that a connection loosened up further back. Check that out

Make sure the GAS, or an upstream valve is off !

OK, enough shouting.

The number one mistake of gas rookies is over-tightening. Remember that gas pressure is so low most leaks can be stopped with your finger or some sticky chewing gum. And do not use heat as suggested, eyebrows take weeks to grow back.

Also don't use ViceGrip pliers. They are too powerful and can squeeze so hard as to crack a cast fitting.

Use pipe wrenches as suggested above. You need 2, small ones are better, a pair of 10" or 8" would be good here.
As Harvey mentioned apply the wrenches in opposite directions, decide which part will move, and which part is stationary.
Then hold the stationary wrench with one hand, while pushing or pulling the other to remove fitting.
It's much easier doing it than describing it.

Since you've been to the store, did you get a Cap for the pipe, or a Plug for the coupling?

 

[Big papa]

Good stuff I was hoping someone would atleast rule out the heating of the pipe theroy.

 

[LGTWhit]

All set, these pipe wrenches were beast. Broke them free no problem. Yes capt, the whole pipe spun half turn. After completing job I tightened other side. Used yellow Teflon tape and gas pipe sealer and didn't over tighten cap. Will test in an hour. Oh yeah, I turned off spin valve in propane tank and upstream valve before capped pipe before work.

Nice Job!

Things always go better with the right tools.

Now on to the insert.

 

[LGTWhit]

Leaving that to the contractor. I want it done to a T. Don't want to be seen on the news cause of a rookie mistake!

 

[LGTWhit]

Yes, like that. I couldn't just cap it because the pipe would have been too long. I suppose I am committed to solid fuels now, but I don't see that as a problem. We only have LP ($$$$) and natural gas won't be coming down the street in my lifetime.

Couldn't you just pull the piping through the box instead of cutting

 

[vgrund]

No way, that thing was mortared in solidly. I left what remained in place as a structural element.

 

[LGTWhit]

Ill let the contractor figure it out
