double check you stove pipe and flue pipe, and just as important CHECK ALL OF YOUR SMOKE DETECTORS AND CARBON MONOXIDE DETECTORS!! Change the batteries and clean as needed. Even if you have hard-wired detectors, you need to ensure they are clean and are working properly. I consider taking these measures to be more important than anything else you can do to ensure you and your family's safety. If you do not have these devices in you home, SHAME ON YOU! Get them, especially as a woodburner! Be safe this heating season!!
