I'm a novice at using fire for heating our home, and my newish PE Summit is the primary heating source during cold weather. I burn everyday from mid October until sometime in March with two cut down ash trees in 2016. However, I don't burn overnight. This soot was from my 2nd year with the insert, and the installer's sweep told me it had to be professionally cleaned to keep up with the warranty (that was the last time he will ever get money from me). Just recently, I bought a sooteater and cleaned it myself yesterday. Approximatley 2 quarts of dried soot came down my 20 foot chimney liner So is 2 quarts too much and safe for all the wood I am burning, or should I clean more often? By looking at the characteristics of the soot, my wood is dried enough correct? Thank you
