Add some dilute sulphuric acid and a few pieces of granulated zinc to reduce any Fe3+ ions formed in the burning process back to Fe2+. The solution can then be made up to a known volume in a volumetric flask and volumes can be removed by pipette for titration with your original (very dilute) permanganate solution.
