Lopi insert installed two months ago. Quality, qualified installer did a great job. New Flue, Flue off-set, used stove that was looked over by the installer (who sells this stove).
Finally got around to building hearth on Thursday. Threw up some Durrock around the stove and noticed a very strong draft all of a sudden. Going to check w/ the installers on that - I suspect it's coming around the flue insert into the old firebox.
All was great until tonight. Threw a couple of firestarters in and a small piece of pine to get things going... noticed the draft wasn't very strong. Watched it for a few minutes. All of a sudden there's smoke coming out of the fan area (air intake).
Put out fire and trying to get the smoke out of the house.
W-T-F could cause a flue block this quickly?
