Don't surround the stove too closely with your windshield it can melt the rubber o ring inside, causing the gas to leak
Don't surround the stove too closely - it reflects the heat and causes the gas to expand and has been known to cause the cartridge to explode.
I use a 'poundshop aluminium Turkey tray' cut into an oblong, formed into a 3/4 circle and stands a few inches away from the stove. Keep the wind off but allows the reflected heat to dissipate.
In really cold weather the wind-break can be moved 'inwards' and the additional heat helps keep the gas flowing (as we all know, as gas is used the pressure reduces and the gas inside cools and we get 'ice' on the outside of the cartridge).
The best way is to use a pie dish - keeps the wind off and removes all possibility of reflected heat.
