PROPANE HEATER TANK

Check local building codes to be sure of materials permitted for your purpose first. A call to the building safety department of your local municipality will usually get you the answers you need. If not, check out a book called the Uniform Plumbing Code at your local library.
Flared copper pipe is usually OK to convey gas to appliances. The connections are considered mechanical joints. If you mean the corrugated type, the length is limited for different appliances because they are not as strong as other pipes. Remember that gas leaks are deadly and you should check carefully with soapy water for bubbles when you are done.
You should also know it is always in the code that a licensed gas fitter is the only one allowed to turn on a gas supply once it is turned off. He/she will only do that after it is inspected by the local authority. That is for safety reasons. You can probably do it safely yourself as long as you take the proper precautions and test it thoroughly when you are done. To be honest, most water heaters are changed out without the required inspection but I wanted to impress the safety issue. Be careful and good luck.
