I bought the 360 Degrees Furno Stove from anaconda. On the packaging it says to use the stove with a 80% butane - 20% propane canister, certified to EN417. however i can't find a 80-20 canister, will using another type of canister cause unwanted hazards? and where can i find a canister of this type, i've tried rays outdoors,anaconda and bunnings.
