I want to convert my propane gas grill on the deck to natural gas. Inside the basement I have an existing 1/2 copper tubing gas line that is accessible. I would like to 'T' off it using compression joints and run a line, about 12 feet, out under the deck and then up to the grill. The grill is a dual fuel convertible grill, which I will convert with a kit. Can I use some 5/8 inch copper tubing the I already own to run the extension? Are there any other things that I should take into consideration?

Thanks.
 
I do hope you realize that converting LP to Natural gas is not just a matter of changing the supply line. I could be mistaken, but I don't think it is possible to do what you want to do. Before spending any time or money, you had better check this out.
 
I do a lot of DIY projects myself but gas is one I will not touch. I didn't think they allowed copper to be used for gas in interior spaces- I thought that had to be threaded "black iron".

I have a buried propane tank in my yard that was installed three years ago by the propane supplier. He also ran the lines to my gas heater (which required the conversion kit) with a tee off that to my gas grill. The buried portion of the line is copper inside a poly sheath and he converted to iron just above grade. He then has a pressure reducer followed by the tee. The lines are all black iron from there, under the deck and poking through, with a ball valve, then a quick connect to a rubber hose to the grill. He cut off the pressure reducer that came with the grill, and used a simple barb to barb connection to connect the hoses.

He pressure tested the whole system then soaped the joints for good measure.
 
gas

He said it is a convertible one and has the kit, so he must have the new regulator and jets unless the LP ones just need adjustments. But, if you really intend to do this yourself, which is not always a smart idean, NO compression or solder joints. ONLY flare or brazed connections. I will not say "silver solder" because then you might consider the current silver bearing soft solders, which are a completely different thing, to be adequate.
 
I mispoke. I will use flared connection connections. The grill is convertable with a kit. My real question is, can I use the 5/8 tubing off a tee where I will tap into the 1/2 tubing? I don't see any restriction on using copper tubing for gas lines.

Thanks.
 
It depends on the BTU/hr rating of the grill whether that would supply enough fuel.
 
I think I'm over engineering this. My main supply source will be 1/2 inch. I'll tee off that to 5/8 inch (because I already have some 5/8 tubing) to the grill. The grill needs only 1/2. It was a stupid question to ask if okay to go from 1/2 to 5/8. Going down in size might be a problem, but not going up, I would think.

The inlet to the gas grill assumes proper pressure and flow up to it...the length of the pipe going to it and how many fittings and turns there are will affect the flow. 1/2" might not be big enough.

tubing

Are you measuring the tubing by the i.d. or o.d., because there is no 5/8" i.d. plumbig tubing. That is strictly a refrigeration size. But if you are measuring the o.d., then 1/2" o.d. tubing is too small to do what you intend to.
 
It would be...
But seriously don't worry about it...
Your plumber will have the right materials and know how to do the job!:cool:
 
Gas line extension

You really need to reread "REDWOOD" posts,
running gas pipe requires a lot more then knowing how to connect
two pieces of pipe together,
you need to know how to correctly size the piping for the demand load ! ! !
Some thing you ! ! Obviously do not know how to do !
Under sizing gas piping can cause carbon monoxide poisoning

not to mention that nice picture of the explosion and fire that
"REDWOOD" posted
that is why plumbers get paid the big bucks, and have to be tested, and large sums of money for liability insurance

i know you won't believe me but all you have to do is "google"
it on the internet i have message alerts ever day on this,
 
tubing

Refrigeration tubing is typically much thinner than plumbing tubing. It is type ACR, not "K", "L", or "M" which are plumbing sizes and grades. I would not use it, but then I would not want to take the chance and have my insurance company foot a liability claim.
 
I wonder how much money I could save if I fashioned a duct tape helmut of some sort. You know, removable but still structurally sound. Getting this stuff off is time consuming and the last few wraps really suck.
 
I bet it's a lot like this...

Certainly better than having your head explode....

Anyway back to the DIYer gas installation...
