Canister stoves burn pressurized fuel that emerges from the canister in a vaporized state. As a result, they are much less prone to clogging and are generally extremely reliable. On the downside, they do not operate well below zero degrees Celsius.
Fuel mixtures containing propane, iso-butane, and butane are designed to keep the output constant as the pressure inside the canister decreases. High pressure propane burns first and then lower pressure isobutane and butane. Mixtures that contain propane also tend to perform better at lower temperatures.
Although canisters from different manufacturers may share the same type of valve, your stove is designed to burn a particular fuel mixture. MEC recommends that you use only the canisters designed for your stove. The wrong blend of fuels can clog your stove, cause flare-ups or fuel leaks, and may burn dangerously hot.
If your canister stove stops functioning due to a food boil-over, try pricking the jet with a wire tool to restore its function. If you notice an unusual gas-like smell, or notice fuel leakage due to a seal failure, do not use the stove! Check that the attachments are sound and that the canister is screwed on properly. Bring it by an MEC store for immediate attention.
