Ideas to help cover chimney area against rain?

[rumbaba]

Hi,

I have recently started living in a yurt in Bulgaria and it's my only home.

I am not bothered about having a window in bad weather so expected just to pull the felt/canvas/cotton package over the whole circular centre piece and be able to have the stove on (Mongolian trad drum). But the canvas around the stove fixings/pipe and metal sheet) burned even though I fixed a pad wrapped in foil around the stove pipe. Not good.

Ideas would be much appreciated. Not a very handy person so some kind of

material to pull over would be best. (Not perspex)
