We bought a Century Hearth wood stove two years ago & are having problems with lots of soot on the roof & with a little bit of wind, on the back patio. Just tried to call CFM Corporation, got the wrong CFM Corporation, poor lady who answers the phone - and found out the one who made the stove has gone bankrupt. Went thru the manual, right size flue, right height from the roof. Have tried everything I read, soda cans, dried potato peels & nothing helps. Had the wood stove 2 yrs. (to the day), last stove for about 15 yrs. & no problems. Dry wood, pinion pine - small town, we clean it regularly ourselves. Last year wasn't bad, but more moisture this year & it mixes real well with the soot! Any suggestions, besides a new stove? Can the pipe be to high? Help!
