If you have a pellet stove, it’s important to clean the chimney regularly. This will help keep your stove in good working order and prevent the build-up of ash that can cause problems. To clean the chimney, start by removing all of the ash from the top of the stove. Then, use a vacuum cleaner to suck all of the ash out of the chimney. Finally, use a brush to clean any dirt and debris from the top of the stove.
