Gas Bottle Wood Burner

Step 2 Drain

Unscrew the gas valve in a ventilated open space, preferably outside, away from open flames and sparks.

Turn the bottle upside down, then wait for a lot more gas to come out.

Wait until gas stops coming out, then unscrew the valve from the bottle, which requires plenty of force, and probably a vice. A little more gas should come out.

Turn the right way up, then fill with water, using positive displacement to remove the last of the gas.

Leave the water in until you are ready to cut.

Bottle should now be gas free :)

Just a note to readers - this process may seem like a lot of effort, but "positive displacement" is the only safe way to cut into a gas bottle. I do actually know someone who was injured by cutting into a gas bottle that hadn't been properly displaced of propane!

I also agree with the above statement. The $1 you spend on water will save you many hundreds of dollars in hospital and/or rebuilding your house bills.

I have a regular size propane tank like the ones for grills and stuff.. I wont to make a small stove out of it so i opened the valve to let the gas out and nothing came out so i started shaking the bottle and i could hear fluid in it what can i do to get the gas out? Is there some kind of safety device in the bottle that will only let it out if something is hooked up to it?

there is a shrader valve in the main valve you have to depress it like a tire valve stem
