stove is a 2007 p68, this year I'm using enregex brand pellets in past I've used pelletsales.com hard and soft wood. My stove runs 24 hours a day as it is my only heat source I use. This year I started to notice creosote build up on my fire wall behind my burn pot and also to the right of burn pot on fire wall. It seems to not catch a flame since no flame touches fire wall, but is spreading to the right on fire wall quickly. I cleaned last week scraped creosote off and it came back more vigorously this week. More info, stove was installed professionally to spec with oak 2 years ago my lame,inept, dealer disconnected my oak after I noticed flames and sparks jetting out of my outside pipe, that was there only answer that day. Since then from reading post here, I have re-installed my oak,I was getting creosote with oak working and not working so I don,t see that as an issue.Only other thing is I run A air-o-swiss humidifier that puts out A good amount of mist, to the point that when it's running my gas kitchen range flame burn orange rather than blue, A mystery just solved A few days ago, however I have no idea why that is. Last week on a hope and a prayer I called my dealer, something I don't like to do since they don't have a service guy I can trust for any good advice ever, he's just a kid with one years experience behind him only seems to be there to clean stoves and change out simple parts, I was not surprised he had nothing to add, so I can only hope that someone out there might just know A little bit more as to why my stove is making this creosote. Is it even safe at this point?
