Plenty of people have a log burner and chuck almost anything into it. In our house there are two burners. With one of them, the previous owner admitted that he chucked all sorts inside. With this burner, the flue was thick with tar, the stainless steel liner had rotted through and there was evidence of previous chimney fires.
We've just replaced this burner and had a new flue installed. The installer has told us to only burn stuff that has been unaffected by man - so no purchased machined wood or anything painted or stained. Also, no wood with a higher moisture content that specified by the burner manufacturer.
I guess we are lucky in that we don't have neighbours immediately close by. We're also not in a low emission zone. In our previous place, if I lit a match one of the neighbours would be around to complain about the smoke, well almost.
