I bought a sedore multi-fuel stove so far I love it but the smoke likes to roll out of chimney and go to the ground I am on a hill so it's always pretty windy . The cap is just a cheap one that the chimney installer used . I was thinking a better cap might be better ? The chimney is a custom 5.75 in liner cause the normal 6" is really 6"1/4 and it wouldn't go down my old 6 in tile chimney and it's about 18' feet and crests over the peak by 6 inches . If anyone has any questions about the sedore id be glad to look for them . The stove runs at about 500-600 degrees and the chimney pipe runs at 150-200 . Also the wood I'm burning is extremely dry maybe cut 5 yrears ago. Thanks for reading
