Peter please don't screw around with 100% O2.
If you don't have the right none return valves etc its more than likely that you will put 100% O2 into your gas canister and it will blow up.
Personally I have done something equally stupid in the past on the ground and more by luck than judgment I got away with it.
It took 24hours and a skip full of water to sort out and I was extremely lucky.
From memory and this is out on a limb here.
I think a LPG bottle is at 2 bar at 20deg which is 30psi ish.
Anyway funny things happen at low pressurise when you try and cook. At FL180 boiling point is down to 75degs or less? so you can't make a decent cup of tea and other funny things happen. Which is one of the reasons they don't cook in space the water boils out of most things before it is cooked and you normally end up with warm charred billatong if your trying to cook meat
