I fitted a woodburner myself (well actually I've fitted it several times) and I've had nothing but problems. The main issue has been that within 10 minutes of lighting the woodburner theres an awful heady smell that gave us all sore throats and headaches, the smell would get unbearable. Weirdly enough, the smell never set off either the smoke alarms or the carbon monoxide alarm,we also had the installation checked by a professional fitter. I sold the woodburner and brought another new one. We had to wait for the paint to cure and then hoped we would be ok. Wrong, same problem. We then changed the flue liner for a better quality one and filled the chimney with vermiculite, still to no avail. We have now recently sealed the steel register plate etc with a silicon sealer thats specially designed for temperatures up to 1200oc and designed to be used for woodburner flue pipes and it seems to have at last cured the smell problem, but we've noticed that now everytime we light the burner it pours with steam from the register plate, does anyone else have this problem? Cheers
