One at the top,near the lid and another at the bottom.. put 2 or 3 peices of window screen on top of eachother and cover your hole from the inside.Homedepot sells 4 inch taps for flex.They are peel and stick taps.stand your bucket outside your room and run flex to the top..Fan hooks to the bottom with flex between.bucket and tap.Then another peice of flex from the fan to make it quieter.This will work for about 2 months then do another bag...DO NOT COOK WITH USED BRIQUETS...
