Wow are you guys really having that much trouble with the creosote, I just get a ripping fire going with dry kindling to burn out any residual creosote in the primary firebox, let it go out, hit anything left with a torch then give it it's regular cleaning and then spray it down with fuel oil and transmission oil, done. I'm going to go and get some fresh wood chips today and fire up my new demonstation wood chip boiler. Running it beside the state highway right out in front of my home sure does attract a lot of interest, my show trailer is almost ready for the Bangor Maine logging expo. I will run it at about 20 shows this year ,shut it down between the shows and at the end of the season just scrape out the ash,( NO CREOSOTE ) it is impressive. I can't wait until next heating season as I will be burning wood chips next year instead of firewood, cleaning is simple, brush out the tubes and empty the ash pan, loading is once every 3 to 7 days and it's done with a small tractor instead of my back, almost as easy as burning oil or gas without the feeling of guilt
