I have a St. Croix Afton Bay stove installed in my walk out basement. The installers vented it direct to the outside and just capped it off with no rise. When we use the stove we sometimes get a strong smoke smell (but no visible smoke) in the room. I'm wondering if the install could be affecting this? I'm considering modifying the exhaust so it has a vertical rise on the outside before it is capped off. I've included a couple pictures so you guys can see what I'm talking about.
