Hi all,

Has anyone got any pros or cons for leaving the LPG gas bottle on the top of the 4WD while cooking ?

I have been told that you can and you can't do it. The can't do it said that the bottle has to be below the stove or it can damage to stove. The can do had never heard of this and said as long as the bottle always remains upright then there should be no issues.

We are using 9kg bottles, and while getting it up/down is not that much issue, I would rather leave it on top if possible.

Hmm, I wonder if there is an issue with atatic elecricity as the cynlinder is not 'grounded' other than by the gas itself...

The bottle can be left on top whilst cooking.Keep it upright and the gas pressure is delivered to the stove at the correct pressure via the gas regulator on the outlet valve of the cylinder.Only concern is the hose is long enough to reach the cooker from the roofrack?

Hi John, I'am no expert, but the contents in your cylinder are actually a liquid and the appliance runs of the vapour. It would therefore seem to me that regardless what level the cylinder was in relation to the appliance it would only draw of vapour provided the cylinder was upright so all should be OK?
But....... gas is a pretty volatile product & therefore suggest you check with your friendly LPG distributor. ( not the swap & go man at the Servo) Best of luck & cheers.

John,

I have been leaving the gas bottle on the roof rack and using the BBQ on the ground for some time now and I have not had any problems.

I will turn the gas bottle off first and allow the gas to run out of the hose before I turn the taps off at the BBQ.

Dont know about cooking but LPG has an expansion rate of 240 litres of gas for every litre of liquid. Just someting to think about when mounting your gas bottle. Even a small bottle will make a big bang so make sure its secure.
