'Pressure' stoves
 

This may sound a really silly question, but I don't know the answer.

I have recently bought a Coleman Feather 442 dual fuel stove, and fired it up for the first time last night to see how well it boiled water. Part of the preparation during and after lighting is to pump up the pressure. My question is, do you let that pressure go before you pack it away, or should you carry it with the pressure still built up? I have read through the leaflet quite a few times now and it doesn't say you should, or shouldn't :-s

I just pack mine and don't give a thought to if it still has pressure or not for what it's worth.

The Trangia system says you need to let the pressure out - you do this by letting the flame go out and just let the 'gas' run out through the system - takes seconds. Makes sense to me - I wouldn't want to be carrying a pressurised fuel container on my bike.

I always leave mine pressurised, even over the winter when it isn't used. The one time I left it un-pressurised over the winter it leaked around the on/off valve to the point I couldn't use it when I went camping in the spring. Luckily, I left it with some pressure in it and went out for the day. When I got back I tried it again and it was back to it's usual self. This was a few years ago and I've not had a problem since.

I've had my 533 cooker for about 25 years and that was the only time it's ever let me down. If only everything else was as reliable as a Coleman stove.

Thanks for the advice, even though the responses are contradictory. I hadnt realised that by letting the flame burn down, it was depressuirsing the system. After the flame had died last night and the whole assembly had cooled down, I unscrewed the fuel filler to relieve the pressure but then wondered if it was the right thing to do.

I have a Coleman and never let the pressure drop bertween uses. Matt has a tranga which is different so I don't think the advic is contradictory. if you have a Coleman, pump it up - use it - pack it away.

Thanks George. I noticed that it was a different system, and I have seem it in his vids, but it was the "I wouldn't want to be carrying a pressurised fuel container on my bike" that was contradictory. Sorry for not explaining myself :-)
