Gas pottery kiln

Hi all.
I'm planning to set-up a Nat Gas pottery kiln. The kiln is outdoors, fires 350,000 BTU/hr, about 100' from the meter. Gas company said current meter will do the job.

Is there a safe way to do this hook-up above ground? I live in an area that doesn't have frequent inspections and I would take the whole set-up with me when I move, but I do want to do things super safe.
Rubber gas line an OK option? Flex line?

Any help is appreciated. Thanks!

Welcome to the forums.

I've moved your thread to the plumbing/piping forum as that's what you need help with.

I'm not the plumbing pro but I don't think you'd want rubber gas line laying on the ground. I'm not sure you'd want any type of flexible gas line just laying on the ground.

350kBTU is more than most meters can deliver. The max delivery should be right on the meter. That load may require a meter upsize.

I'll let the others respond on the connecting methods.

Thanks, Pete.
I've gotten mixed thoughts talking to folks in my area, excited to get more input. I guess I'm really trying to hook this thing up but know I'll move in the fairly near future so digging is not attractive, plus the ground is not very cooperative. Propane is an option but tends to be more expensive.

Thanks for your thoughts!

I don't have much (any) experience with above-ground gas piping... but I would think the only method you could use is black steel, but it would need to be supported somehow, and not just laied across the ground.

Rubber or flexible metal I believe is length-limited to about 5', so that won't work.

If there is a fence or wall between the gas meter and kiln you could run the piping above ground mounted to the fence/wall. But, you can not simply have a gas line above ground unsupported and unprotected.

I would look at your meter and confirm that it is capable of delivering enough gas. 250 is what the meters on most of my rental houses can provide which would be too small for your application.

Thanks for the replies.
The meter is capable, I've confirmed that with the gas company.

If I were to disconnect and the gas when not in use would that change things? I'll only be firing this thing up once a month or so.

Thanks again.

When operating the kiln will still consume that same amount of gas regardless of how often you fire it. When it's running it needs up to 350'000 but/hr worth of gas.

There is no approved scenario for a gas line of that size to be run so far outside and be temporary. So, the answer is still "no". You cannot simply lay a hose across the lawn to fuel it.
