wood burner and draught

[nskeates]

hello,

i had an open fireplace that had the basket for logs and coal but i replaced that with a wood burner. the chimney from the wood burner goes up into the othe chimney but i get a draught coming down from around the gap between the wood burner chimney and the original chimney.

is the anything i can use to stuff up there or expanding foam sort of thing to stop the draught. its ok when the log fire is on but when off the lounge gets very cold from the draught.

i have got a draught drawing thing on the very top of the chimney it rotates in the wind and should help the draught but that does not seem to do anything.

any help appreciated as its very cold in the lounge

Our woodburner is fitted with the chimney going up into a chimney liner. There is a stainless steel retention plate fitted at the bottom of the chimney with the woodburner chimney going up through it. The gap between the chimney liner and the chimney is filled with micafill. We do not have any draughts.
