The thinness of the steel made everything feel “sharp”, but all the corners are rounded for safety, making the unit unlikely to actually damage you or your gear in use. Although it will run on car petrol, the additives in the fuel don't always burn off properly in the low-ish temperatures of a camping stove, leading to clogging up and consequent strip down & cleaning. Some of the constituents of car petrol aren't terribly healthy either (look up benzene, for example), and petrol stations often don't like you just buying a bottle full (min sale is usually 2 litres). It's better to use an additive free fuel such as Coleman fuel or Primus Powerfuel if possible (cheaper alternatives such as Aspen 4 or panel wipe do exist, but not so that you would find them during a trip). The wind is the enemy of such alcohol burners. You need to use a wind screen that wraps around the burner and the pot. That way you ensure that the flame is centered at the bottom of the pot. Another detail is that, depending on the environment temperature, once the alcohol is boiling inside the burner, the simmer ring is not airtight, therefore, the alcohol vapor will escape by any path and will continue to burn around the burner uncontrollably. Under these conditions, it is advisable to add a little water (a teaspoon or less) to the alcohol in the burner to waste energy producing water vapor that is not combustible and reduce the amount of alcohol vapor by cooling it a little. A ratio of 85% alcohol in water will work (try your own). As is well known, water is corrosive. It is advisable to dry the burner well when not in use. It fits nicely into the small mess tin and said tin can hold both this stove and the B26 with ease, making it quite a neat little system. The pot stands however are narrow to the mess tin making tipping rather frequent.

Petrol stoves can flare quite high at startup, so aren't good for use inside a tent, and often don't simmer well as the burner has to be kept hot enough to vaporise the fuel before it gets to the jet. If you have a pot that is less than 10cm in diameter, it will not fit on the pot stands. This is a real problem for most titanium mugs that are popular as pots. Mine falls though. I'd recommend a remote canister gas stove such as one of MSR Windpro, Optimus Vega, Primus Express Spider, Edelrid Opilio, Fire Maple FMS-118 (which was being sold very cheaply by Field & Trek as the Karrimor Alpine until fairly recently). The important point is that all these have a pre-heat tube passing through the stove flame, which allows you to run the stove with the canister upside down and avoid the normal gas performance problems in cold weather or at the end of the canister. Start the stove with the canister upright, then turn it over and adjust the flame.

It is provided with a screw cap, which will seal the unit and any remaining fuel for transportation. (Not long term storage) Buy 2, or combine it with another type of stove and you have a setup that will cook the finest of meals. The 3 pieces of stainless clip together and the steel insert for the burner just pushes in to place. It’s so simple, but is a little fiddly until you get used to it. Then drop the burner in to place in the central hole. Having removed the lid and not quite filled it with meths beforehand. I tried twice to use the cap to create a smaller flame but unless it was nearly completely open, the flame would go out moments after I put my saucepan on. The Triangle was not available, but now, in 2022, it has become available again in a slightly different design. It looks a bit better, but there was never a problem with the older one. It is rumoured that they discontinued it because of a patent or some such infringement.

Methylated spirit (meths). I do not recommend using anything else. Meths is readily available and cheap. It works the best and is safe. You can buy it in 5 litre containers which makes it really cheap. A few years later I had discovered Trangia had done just that, to create 'add ons' that would enable the design classic that is the faithful Trangia to run on other fuels including gas, so if I want to revisit that past idea again, it will at least be easier this time around, but just to alert you to the fact these days they don't just run on meths.

Specifications

Excellent build, folds super flat and is basically a no brainer to anyone owning a trangia, especially since it makes any setup a double burner solution while adding barely any weight nor bulk. Tried it outside for the first time. There was not much wind, plus my balcony floor is pretty well protected. The flames could get high enough to burn my hand (did a bit) when i used the removable handle for my saucepan. They were really unpredictable (from one side to the other) which made it dangerous. I don't put more then 2/3 of methylated spirits. Tested it 3 times all ready without the expected results. My next stove of which perhaps I will get next month will be a Stainless 'Wild Woodgas' stove so in terms of fuel I can use contained woody material to create flammable gas as fuel or I could use my Trangia meths burner in it, as my outdoor cooking needs have changed.

Using a flint and steel it is easy to light, and I've found a good puff will blow it out (although this isn't approved by Trangia). Failing that and inverted mug will starve the flame of Oxygen.Your mileage will vary, but in the real world, that’s how it works for me. What fuel does a Trangia use The best alternative fuel is EKOFUEL bioethanol, which is specifically stated as being for Trangia stoves. Trangia says it is fine to burn ethanol above 70%, but it will be sooty. Buying a Trangia Triangle – beware
