Does anyone out there have problems with massive flow of creosote at the rear right side cleanout, behind the oven? If so, how have you dealt with it. I have been given the suggestion to freeze it, then chip out, by a welder friend. I don't understand why it has gotten so bad. The stove is brought up to high temps, for a spell every day, trying to keep the issue at bay. My wood is fir, and sometimes pine, so that doesn't help. I tried to stick to fir, but it really made no difference. Any experience out there? Thanks!
