Flue sleeves

[Celticknots]

Hey guys,

I'm in the process of putting together a wood burner for my small canvas bell tent. I'm conscious of the fact that the tent one of the polish army poncho bell tents and that there is likely to be a lot of heat still in the flue when it meets the gap in the canvas.

Does anybody have and advice for an insulating sleeve or method by which i can protect the canvas and stop it burning the tent down?

Also, can anybody give advice on how much room i should put below the stove?

thanks guys

Im sure I saw someone on here used a sheet of silicon sewn into the tent and a tight fit to the flue.
