I have a 2 flue chimney. In the upstairs fireplace I have a Neo 2.5 insert. Everything works great. 2 weeks ago for the first time I lit a fire in the fireplace in the basement. Everything seemed fine, but when I came upstairs my Neo was blowing smoke out of the fan exhaust. I have never had this issue before I lit the fire in the basement fireplace.
The Neo is connected to a 6" liner that runs the length of the chimney with a cap on it. What could cause this. As long as there is no fire in the basement everything works like it should. I have not had any issues in the past. Could it be pulling smoke from the other chimney flue? Do I need to just extend the liner on the upstairs flue? Where does the Neo draw air into the blower? Any help would be appreciated. Thanks!
