Hi i had a new jotul 602 woodstove put in my finished basement with an exterior double wall stainless chimney. it works great for heating my small home. but when i'm not using it i get a giant draft coming out. it makes my whole house smell like the inside of a chimney and i can see the wind coming out when i hold a lighter in front, it brings more cold in than i wanted. is there something i should do or am i stuck with it...
